Hi, I want to make a select from mysql to show some data in page. To show a table with data from mysql but limited to only 5 and this to show total number of rows. I'm thinking to make two selects. SELECT count(*) FROM table1 and after that to use mysql_num_rows to count total number in that table. Then another SELECT name,prename FROM table1 LIMIT 1, 5 to show only first 5 rows. It's there a way to use only one select insted of two but having the same results ? Thanks

I am trying to use a <select> <option> to display text on a web page. The data comes from a database. This is what I am attempting: When an option is selected and submit button clicked them some text will be displayed. At the moment I do have text on the web page, but none of the selected options change this. I have four pieces of text: Page 1, Page 2 etc. At the moment Page 4 text is displayed. I would like each piece of text to be displayed. This is the php: <?php // Connect to the database $pdo = new PDO("mysql:host=localhost;dbname=###", "###", ""); $sql = "SELECT * FROM testdb ORDER BY id"; try { $stmt = $pdo->prepare($sql); $stmt->execute(); $data = $stmt->fetchAll(); } catch(Exception $ex){ echo ($ex -> getMessage()); } ?> This is the html: <form name="###" method="post" action="#"> <p></p> <select onchange="reload(this.form)"> <option>test one</option> <?php foreach ($data as $output) { ?> <option value=''><?php echo $output['header']; ?></option> <?php } ?> </select> <br> <button type="submit" value="submit">Submit</button> </form> <?php echo $output['pages']; ?> I would appreciate help with this. However, from previous attempts at adding data to a page I used isset() and I think $_POST(), possibly together. If these are the things I need to use, then please could you include their usage within any examples you feel would help. Thank you.

I have a php program that calls a function in my class to populate a select tag for display in the page. For some reason I cannot seem to discover, it retrieves the information, it correctly creates the option tags, but then when it displays the dropdown dialog box, the very top entry is missing. I sure could use another set of eyes on this to tell me what I'm missing as I know it has to be something simple. Here is the php page code that calls the function: if ($redisp==1) { $table_ex_entries .= "<table><tr>"; for ($x=0; $x<10; $x++) { //get the categories list with the selected one highlighted in the list $selected = $page->getGroupsForEntriesForm3($_SESSION['UID'],$entry_cat[$x]); //get the value for the off hours radio button if (isset($entry_offhrs[$x]) && $entry_offhrs[$x]=='y') { $set_checked_y = "checked='checked'"; $set_checked_n = ""; } else { if (isset($entry_offhrs[$x]) && $entry_offhrs[$x]=='n') { $set_checked_n = "checked='checked'"; $set_checked_y = ""; } else { $set_checked_n = "checked='checked'"; $set_checked_y = ""; } } $table_ex_entries .= "<tr>"; $table_ex_entries .= "<td><input size='12' name='date" . $x . "' type='text' value='" . $entry_date[$x] . "' id='datetimepicker" . $x . "'></td>"; $table_ex_entries .= "<td><input size='12' name='id" . $x . "' type='text' value='" . $entry_id[$x] . "'></td>"; $table_ex_entries .= "<td><input size='18' name='name" . $x . "' type='text' value='" . $entry_name[$x] . "'></td>"; $table_ex_entries .= "<td><select width='250' name='cat" . $x . "' value='" . $selected . "</select></td>"; $table_ex_entries .= "<td><input size='43' name='desc" . $x . "' type='text' value='" . $entry_desc[$x] . "'></td>"; $table_ex_entries .= "<td><input size='6' name='hrs" . $x . "' type='text' value='" . $entry_hrs[$x] . "'></td>"; $table_ex_entries .= "<td>Yes<input name='offhrs" . $x . "' type='radio' value='y' " . $set_checked_y . "> No <input name='offhrs" . $x . "' type='radio' value='n' " . $set_checked_n . "></td>"; $table_ex_entries .= "</tr>"; } $table_ex_entries .= "</table>"; } Here is the div in the html body (it displays fine as I have some javascript that determines which div to display based on the $redisp==1 show in the above code snippet) <div id="re_entry" style="display:none"> <p align="center"> *<b>Date/Category/Description/Hours are REQUIRED fields</b> <br>Please correct your entries and click Add Entries again to proceed. <br> </p> <?php echo $table_header; ?> <?php echo $table_ex_entries; ?> </div> And here is the function that it calls to create the option tags for the select tag in the first set of code building the html table. Oh and I do have categories preferences so it is retrieving just my list not the whole list in this function. public function getGroupsForEntriesForm3($uid,$category) { $out = ''; $cats = array(); $cat_id = array(); $catname = array(); $dbh = $this->rdb; //check to see if the user has set preferences for their list of categories $dbh->query("SELECT Categories FROM Users WHERE ID = :id"); $dbh->bind(':id', $uid); $row = $dbh->single(); $user_cats = (isset($row['Categories']) ? $row['Categories'] : ''); if ($user_cats == '') { //no special preference for categories so go get them all after getting the user's group ID $dbh->query("SELECT GID FROM Users WHERE ID = :id"); $dbh->bind(':id', $uid); $row = $dbh->single(); $gid = $row['GID']; $cats = $this->getCategories($gid); } else { //user has preference for categories so only go get the ones they have in their preference list to create the select options $dbh->query("SELECT ID, Name FROM Categories WHERE ID IN ($user_cats) ORDER BY Name"); $rows = $dbh->resultset(); $xx=0; foreach ($rows as $row) { $catname[$xx] = $row['Name']; $cat_id[$xx] = $row['ID']; $xx++; } } $dbh = NULL; $select_opt = ""; for ($xx=0; $xx<count($rows); $xx++) { //echo "category ID inside the function is set to " . $category . "<br>"; //echo "catname while while creating the select options set to " . $catname[$xx] . "<br>"; if ($category == $cat_id[$xx]) { //echo "match category is " . $category . " and cat_id[xx] is " . $cat_id[$xx] . " and catname[xx] is set to " . $catname[$xx] . " and xx is set to " . $xx . "<br>"; $select_opt .= "<option selected value='" . $cat_id[$xx] . "'>" . $catname[$xx] . "</option>"; } else { //echo "category is " . $category . " and cat_id[xx] is " . $cat_id[$xx] . " and catname[xx] is set to " . $catname[$xx] . " and xx is set to " . $xx . "<br>"; $select_opt .= "<option value='" . $cat_id[$xx] . "'>" . $catname[$xx] . "</option>"; } } return $select_opt; } Thanks in advance! Ches

I have a timeclock application where you can add entries into a table. One of the columns is a <select> dropdown tag. If you do not enter one of the required fields, I redisplay the values entered so the user can correct the entries and resubmit to save them. Everything saves (posts) except the <select> dropdown value. The dropdown does show properly, even with the properly selected value. But if you change the value, it doesn't update. It retains the original value. Here is the function from STOP_Timeclock.php class that does the form: public function add_entries_page($msg) { $redisp = $_SESSION['redisp']; $out = ''; $offhrs = "N"; $dbh = new Database; //display the last entry the user saved to the database $dbh->query("SELECT * FROM Entries WHERE UID = :uid and GID = :gid order by Date DESC Limit 1"); $dbh->bind(':uid', $_SESSION['UID']); $dbh->bind(':gid', $_SESSION['GID']); $rows = $dbh->resultset(); foreach ($rows as $value) { $msg .= "Your last entry was: " . date('m-d-Y',strtotime($value['Date'])) . " for: " . $value['Description'] . " - " . number_format($value['Hours'],2,'.','') . " hour(s) were recorded. <br>"; } $select = $this->getGroupsForEntriesForm($_SESSION['UID']); //$select2 = $this->getGroupsForEntriesForm3($_SESSION['UID'],$_SESSION['array_category']); $caption = 'If you leave the Date Box empty, it defaults to today. *<b>Date/Category/Description/Hours are REQUIRED fields</b> <br><br>'; $head = array(array('name' => 'head', '1' => 'Date *', '2' => 'Ticket ID', '3' => 'Ticket Name', '4' => 'Category *', '5' => 'Description of Work Done *', '6' => 'Hours *', '7' => 'Off Hours(Y/N)' )); if($redisp == 0) { $body = array(); unset($_SESSION['array_id']); unset($_SESSION['array_name']); unset($_SESSION['array_category']); unset($_SESSION['array_desc']); unset($_SESSION['array_hours']); unset($_SESSION['array_offhrs']); for ($i = 1; $i < 11; $i++) { $row = array($this->xhtml->input(array('type' => 'text', 'id' => "datepicker$i", 'class' => 'entries_field_1', 'name' => 'DATE[]' )), $this->xhtml->input(array('type' => 'text', 'name' => 'ID[]', 'class' => 'entries_field_2' )), $this->xhtml->input(array('type' => 'text', 'name' => 'NAME[]', 'class' => 'entries_field_3' )), $select, $this->xhtml->input(array('type' => 'text', 'name' => 'DESC[]', 'class' => 'entries_field_5' )), $this->xhtml->input(array('type' => 'text', 'name' => 'HOURS[]', 'class' => 'entries_field_6' )), $this->xhtml->input(array('type' => 'text', 'name' => 'OFFHOURS[]', 'value' => $offhrs, 'class' => 'entries_field_7' )) ); $body[$i] = $row; } } if($redisp == 1) { $body = array(); $name = $_SESSION['array_name']; $id = $_SESSION['array_id']; $category = $_SESSION['array_category']; $desc = $_SESSION['array_desc']; $hours = $_SESSION['array_hours']; $offhrs = $_SESSION['array_offhrs']; $dates = $_SESSION['array_dates']; $max_count = $_SESSION['max_count']; for ($i = 0; $i < $max_count; $i++) { $selected = $this->getCatName($_SESSION['UID'], $category[$i]); $row = array($this->xhtml->input(array('type' => 'text', 'id' => "datepicker$i", 'class' => 'entries_field_1', 'value' => $dates[$i], 'name' => 'DATE[]' )), $this->xhtml->input(array('type' => 'text', 'name' => 'ID[]', 'value' => "$id[$i]", 'class' => 'entries_field_2' )), $this->xhtml->input(array('type' => 'text', 'name' => 'NAME[]', 'value' => "$name[$i]", 'class' => 'entries_field_3' )), "$selected", $this->xhtml->input(array('type' => 'text', 'name' => 'DESC[]', 'value' => "$desc[$i]", 'class' => 'entries_field_5' )), $this->xhtml->input(array('type' => 'text', 'name' => 'HOURS[]', 'value' => "$hours[$i]", 'class' => 'entries_field_6' )), $this->xhtml->input(array('type' => 'text', 'name' => 'OFFHOURS[]', 'value' => "$offhrs[$i]", 'class' => 'entries_field_7' )), ); $body[$i] = $row; if(isset($_POST['CAT'])) { $_SESSION['cats'][$i] = $_POST['CAT']; } else { $_SESSION['cats'][$i] = $category[$i]; } } } $data = array_replace($head, $body); $table = $this->xhtml->table2($data, $caption, array('class' => 'add_time')); $table .= $this->xhtml->input(array('type' => 'submit', 'value' => 'Add Entries' )); $form = $this->xhtml->form(array(array($table), ), array('action' => BASE .

SELECT user_id FROM users WHERE active = :active ORDER BY RAND() LIMIT 1 The above query works. But what if the users table is filled with thousands of users? Will this query break or be very slow? If so, what's the alternative solution to this?

Hi, Thanks for taking the time. I'm trying PDO for the first time and I'm trying to make a CRUD codebase. I can insert but I have trouble with the select statement and iterate through the data, Apache gives me this error: Fatal error: Uncaught Error: Call to a member function fetch_assoc() on boolean in index.php:38 This is line 38: $getName = $result; while( $row = $getName->fetch_assoc() ){ echo $row['name']; } This is my code: $pdo = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password); // set the PDO error mode to exception $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $pdo->prepare("SELECT name FROM users"); $stmt->execute(); // set the resulting array to associative $result = $stmt->setFetchMode(PDO::FETCH_ASSOC); $getName = $result; //Iterate through the data // line 38: while( $row = $getName->fetch_assoc() ){ echo $row['name']; }

Hello there friends I have an select box and I would like to define the alue of the selects with array. Like this: var price_list= new Array(); price_list["-"]=0; price_list["bronze"]=5; price_list["silver"]=10; price_list["gold"]=15; The I have a Selectbox where <form action="" id="metal" onsubmit="return false;" <select id="a" name="metals" class="form-select"> <option value="-">-</option> <option value="bronze">bronze</option> <option value="silver">silver</option> <option value="gold">gold</option> </select> And performig calculations with following script (that works fine if the value is directly in select). And obviously there is another select (#b) but that is just numbers so I didn show it here. $(document).ready(function() { function compute() { var a = $('#metals').val(); var b = $('#b').val(); var total = a * b * 1.22; $('#result').text(total); } $('#metals, #b').change(compute); }); I just get returned NaN If you have an answer then please hit

Im having trouble on my php script. it is working on my computer but when I put it in x10hosting it fails and gives an error 500. I tried tracing the problem and I found out that it happens if I call get_result. Here is the part code: $username = strtolower(filter_input(INPUT_POST, 'username')); $password = filter_input(INPUT_POST, "password"); $remember = filter_input(INPUT_POST, "remember"); $result = array(); include 'Connection.php'; $query = "SELECT Number, Username, Password, Alias, Level FROM user WHERE Username = ?;"; $stmt = $conn->prepare($query); if(!$stmt->prepare($query)) { die( "Failed to prepare statement."); } $stmt->bind_param("s", $username); $stmt->execute(); echo $stmt->error; //error hapens here $selectResult = $stmt->get_result();

I'm looking to replace a select dropdown with images. My current code for the drop down is <div class="app_services_dropdown_select"> <select name="app_select_services" class="app_select_services"> <option value="1" selected="selected">Class IV MOT (Up to 3,000KG)</option> <option value="2">Class VII MOT (3,000KG - 3,500KG)</option></select> <input type="button" class="app_services_button" value="Show available times"> </div> Which is generated by this code: $s .= '<div class="app_services">'; $s .= '<div class="app_services_dropdown">'; $s .= '<div class="app_services_dropdown_title">'; $s .= $select; $s .= '</div>'; $s .= '<div class="app_services_dropdown_select">'; $s .= '<select name="app_select_services" class="app_select_services">'; if ( $services ) { foreach ( $services as $service ) { $service_description = ''; // Check if this is the first service, so it would be displayed by default if ( $service->ID == $appointments->service ) { $d = ''; $sel = ' selected="selected"'; } else { $d = ' style="display:none"'; $sel = ''; } // Add options $s .= '<option value="'.$service->ID.'"'.$sel.'>'. stripslashes( $service->name ) . '</option>'; } } $s .= '</select>'; $s .= '<input type="button" class="app_services_button" value="'.$show.'">'; $s .= '</div>'; $s .= '</div>'; And I really want an image of a car as value 1 and a van as value 2, plus I really want it to submit on click rather than having the button. Is it possible to replace the dropdown with images instead or would I need to use a radio button, then style it using an image? You can see my current dropdown in use here

Hi. I have 2 problems which I'm hopeing someone can help me with. 1. For the following script to change the pages language, I would like it so that whichever option selected is set on the page (i.e. if you select Euskal, the select box stays set as Euskal, and not Espanyol as it does at the moment) <form name="Language" action="" method="post" id="Language"> <div class="btn-group"> <?php $uri = strtok($_SERVER["REQUEST_URI"],'?');; $url="http://".$_SERVER['HTTP_HOST'].$uri; ?> <span class="btn btn-primary"> <select name="lang" onchange="javascript:change_langs(this.form)"> <option value="Esp">Espanyol</option> <option value="Eng">English</option> <option value="Cat">Catalan</option> <option value="Bas">Euskal</option> <option value="Gal">Galego</option> </select> </span> </div></form> 2. I have 2 dropdown lists in the following format: <select class="form-control" name='category'> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="A"))?"selected='A'":""); ?> value='A'><?=getlg($lang,"A")?></option> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="b"))?"selected='b'":""); ?> value='b'><?=getlg($lang,"b")?></option> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="c"))?"selected='c'":""); ?> value='c'><?=getlg($lang,"c")?></option> </select> <select class="form-control" name='category'> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="D"))?"selected='D'":""); ?> value='D'><?=getlg($lang,"D")?></option> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="e"))?"selected='e'":""); ?> value='e'><?=getlg($lang,"e")?></option> <option <?php print ((isset($_GET["category"]) && ($_GET["category"]=="f"))?"selected='f'":""); ?> value='f'><?=getlg($lang,"f")?></option> </select> However, I require just one dropdown list with catagories A and D as the main item. Catagories b & c should be a sub category of A, and e & f should be a sub category of D Any help would be appreciated. Thanks

Hello. I'm a newbie so sorry if this isn't the best forum to post my problem. I am using a MySQL and PHP to create a web app. I have authentication, and I can register users. I also have a form that users provide information and it is successfully inserting data into a table in my database. I will use fictional fields for my database table called meal_info: username dateStartedDiet numberMealsPerDay costPerMeal Problem: Select user-specific data from the MySQL database, using Session username to select only the current user's data, then display it and do some calculations. Here is thecode at the top, and I am fairly sure it's working: session_start(); //execute commone code require("common.php"); //includes code to connect to database, etc. if(empty($_SESSION['user'])) { // If they are not, we redirect them to the login page. header("Location: login.php"); // Remember that this die statement is absolutely critical. Without it, // people can view your members-only content without logging in. die("Redirecting to login.php"); } Here is the part of the code that has to do with displaying user data: $userID = $_SESSION['user']['username']; //create a variable that is the session username which is identical to the field in our MySQL table $query = "SELECT * FROM meal_info WHERE username = $userID"; //our SELECT statement $result = db->query($query); //execute the query $row_count = $result->num_rows;//count the rows in the table and place in variable to use in incremental loop code for ($i = 0; $i < $row_count; $i++) : $row = $result->fetch_assoc(); //for each row in the table, fetch and create and array $dateStart = $row['dateStartedDiet']; $numberMeals = $row['numberMealsPerDay']; $costMeal = $row['costPerMeal']; echo $dateStart; echo $numberMeals; echo $costMeal;

I have a table called "playlists", and a table called "musics". In the musics table, there is a column playlist_id which references the playlist that each music is contained. I'm using api calls to display information on the site with JavaScript, so I need to return a JSON. I need the json with the following structure: [ Playlists: [ { Name: "etc", musics: [ { name: "teste.mp3" }, { name: "test2.mp3" } ] }, ... ] ] And this is my code: $query = $con->prepare("SELECT * FROM playlists WHERE user_id = :id"); $query->execute(array("id" => $userID)); $playlists = $query->fetchAll(PDO::FETCH_ASSOC); foreach ($playlists as &$key) { $query = $con->prepare("SELECT * FROM musics WHERE playlist_id = :id"); $query->execute(array("id" => $key['ID'])); $songs = $query->fetchAll(PDO::FETCH_ASSOC); $key['musics'] = $songs; } There's a way to avoid this loop?

Hello, I don't know if this is possible. I want to make a switch between pages, lets say i have more than 100 pages and each page have a unique name.php. So what i want to do is when page equal to random-page.php SELECT * FROM `jobs` WHERE title LIKE '%news%' And for example how it should be, but i don't know what is exactly wrong here and how to fix it. $sql_q; $path=$_SERVER['PHP_SELF']; $page=basename($path); switch("$page") { case 'index.php': $sql_q = 'SELECT * FROM `jobs` WHERE `title` LIKE '%news%' LIMIT $p_num, $per_page'; break; case 'jobs.php': $sql_q = 'SELECT * FROM `jobs` WHERE `title` LIKE '%jobs%' LIMIT $p_num, $per_page'; break; case 'region.php': $sql_q = 'SELECT * FROM `jobs` WHERE `title` LIKE '%region%' LIMIT $p_num, $per_page'; break; } And here: $getquery = mysql_query("$sql_q"); Is that possible somehow ? Thanks.

I am trying to create a simple forum in a MVC architecture. This is my database setup (the relevant part): Table: forum_categories `forum_categories` ( `cat_id` INT( NOT NULL AUTO_INCREMENT, `cat_title` VARCHAR(255) NOT NULL, `cat_desc` TEXT NOT NULL, PRIMARY KEY (`cat_id`), UNIQUE KEY (`cat_title`) Table: forum_topics `forum_topics` ( `topic_id` INT( NOT NULL AUTO_INCREMENT, `cat_id` INT( NOT NULL COMMENT 'foreign key with forum_categories table', `user_id` INT(11) NOT NULL COMMENT 'foreign key with users table', `topic_title` VARCHAR(255) NOT NULL, `topic_desc` TEXT NOT NULL, `topic_date` DATETIME DEFAULT NULL, PRIMARY KEY (`topic_id`), FOREIGN KEY (`cat_id`) REFERENCES forum_categories (`cat_id`) ON DELETE CASCADE ON UPDATE CASCADE Example of the functionality, I would like to achieve: Category 1 has cat_id = 1 Category 2 has cat_id = 2 Topic 1 has cat_id = 1 Topic 2 has cat_id = 2 Now when category 1 is selected I just want topic 1 to show. If category2 is selected I just want topic 2 to show. This prepared SQL statement achieves that: PREPARE stmnt FROM 'SELECT * FROM forum_categories fc JOIN forum_topics ft ON fc.cat_id = ft.cat_id WHERE fc.cat_id = ? ORDER BY ft.topic_date DESC'; SET @a = 1; EXECUTE stmnt USING @a; My Problem: I would like to move this functionality into my PHP MVC structure.

Hi All, The Problem: I'm trying to learn how to take records from the NAME row of one table (i.e. Tom, Jim, Chris, Mike) and put them into a SELECT (drop down menu) box, then select a name and save it to a DIFFERENT table where the row is also called NAME, and THEN have that selection I just saved show in the SELECT box as SELECTED when the page refreshes. I have found a hundred websites showing how to bind a SELECT box to a table and put them into a SELECT box via $key => $val and even how to save it to ANOTHER textbox on the page, which is a lot easier, but never a step further as described in the first paragraph above. Seems unbelievable to me since it's so common. Maybe I'm just not using the proper search terms/keywords. Here's an example: Let's say you wanted to notify 3 people of your birthday. So, on the notification page, you would enter three names of people you would want notified all in separate input textboxes with [keys]. So, you enter John, Chris, and Tom into three text boxes and save the page. Done. Now, on another page, I have -- say .... five select boxes. For arguments sake, let's just say I click on all of them one at a time. In each of them, I would only see three names (John, Chris, and Tom). Now, in the first SELECT box I click on John. In the second select box I click on Chris, and on the third I click on Tom. Then save the form. I would like to see John, Chris, and Tom in the first three boxes after refreshing and I would like to see SELECT A NAME on the last two Select boxes that we never did anything with. Remember, there are NO default names in the first table with row called NAMES. They are populated by the user and saved to the row. I'm attaching an image of what the page looks like that I want to see the names and be able to select them. Does anyone have a link to a site that shows how to do this... or maybe have something very basic that would show me the process? Or, if not too difficult, maybe you could show me? Thanks in advance for any help!

I have searched this forum as well as over 200 other forums and have not found the answer that is specific to my question. I have shortened my code drastically to assist in resolving this quickly - I have a search form that has criteria for the search criteria with "virtual" "columns" in an array but it's not working. If I search one column at a time it works just fine but when I try to search 8 columns with one select I get the following error: SELECT Error: Unknown column 'achievements' in 'where clause'. When a user selects search in Achievements, I need it to look at all 8 columns that are associated with achievements and bring back the results that match - the same as if the user selects search in Associations, I need it to look at all 5 columns and bring back the results that match. My shortened code is as follows: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Search</title> </head> <body> <form name="search" action="" method="POST"> <p>Search:</p> <p> Achievements/Associations: <input type="text" name="find1" /> in <Select NAME="field1"> <Option VALUE="achievements">Achievements</option> <Option VALUE="associations">Associations</option> </Select> <br><br> Secondary Education: <input type="text" name="find2" /> in <Select NAME="field2"> <Option VALUE="edu1sectype">Highest Certificate Attained</option> <Option VALUE="edu1secname">Highest Grade Passed</option> <Option VALUE="edu1secinst">Name of High School</option> <Option VALUE="edu1secdate">Date Completed</option> <Option VALUE="edu1secinsttyp">Type of Institution</option> <Option VALUE="subjects">Subjects</option> </Select> <br><br> <input type="hidden" name="searching" value="yes" /> <input type="submit" name="search" value="Search" /> </p> </form> <?php $searching = $_POST['searching']; $find1 = $_POST['find1']; $field1 = $_POST['field1']; $find2 = $_POST['find2']; $field2 = $_POST['field2']; if ($searching =="yes") { echo "<br><b>Searched For:</b> $find1 $find2<br>"; echo "<br><h2>Results</h2><p>"; //If they did not enter a search term we give them an error // Otherwise we connect to our Database include_once "connect_to_mysql.php"; mysql_select_db("table_name") or die(mysql_error()); // We preform a bit of filtering $find = strtoupper($find); $find = strip_tags($find); $find = trim($find); $find = mysql_real_escape_string($find); $field = mysql_real_escape_string($field); $data = mysql_query("SELECT * FROM table_name WHERE upper(".$field1.")

Hello All, I've added search to my CMS and one column of data in particular is a date column. My whileLoop spits out data I want however it sorts the date field ASC but I need is DESC. I've tried adding the ORDER BY in several different ways however I keep getting an error... what would be the best approach to get it to sort the way I want using my current SELECT statement $search_sql = " SELECT * FROM tracking INNER JOIN sender ON tracking_sender_id = sender_id INNER JOIN method ON tracking_method_id = method_id WHERE (tracking_recepient LIKE '%" . $_POST['search'] . "%')"; the above code works fine but the output sorts ASC, can seem to add the ORDER BY in an appropriate manner to get it DESC. Any advice ? Thank you in advance

Hi I'm Steven, 68 yo from Melbourne, Australia. Very - and I mean VERY - new to PHP. Need to retrain for a new career. Posted a query elsewhere

I have the following code: <?php require_once("../db_settings.php"); require_once("../classes/dbHandler.class.php"); require_once("../classes/helpers.class.php"); $db = new DBConnection(); $fetchItems = new dbHandler($db, 'exp_weblog_data'); $return_arr = array(); if (isset($_GET["term"])) { $param = htmlspecialchars($_GET["term"]); $items = $fetchItems->getResultsByTerm($param, 'field_id_5', 10); /* Toss back results as json encoded array. */ echo json_encode($items); } else if(isset($_GET['debug'])) { $param = 0; $items = $fetchItems->getResultsByTerm($param, 'field_id_5', 10); $printArry = new helpers(); $printArry->printArray($items); } It basically pulls information from table "exp_weblog_data" and column "field_id_5". I need it however, to pull relevant information from another table called "exp_weblog_titles" and the column "title". If anyone could help me on this matter I would really appreciate it

Hi guys. I'm strunggling with one mysql query. Please help.

How can I reduce result to show me only product 1 and product 2 based on ID from URL ???? Thanks for any help.

I have a list of students entered into a mysql table using the following fields: id, name, surname, address, towncode, streetcode, Another two tables has been designed so to normalize the schema: One is the Streets table streetcode, streetname, towncode .. and the other one is towns with the following fields: towncode, townname Now i need to design a form using php to filter students depending on the town (I select using the SELECT element of a form) , and as well on the street (I select using the SELECT element of a form) which fall under that town. Can someone help me out with this issue. Sorry but I am new to PHP!!!!!!!

I have a database with the table name "Controllers" and the primary ID and other fields. Each time their is an event (alarm) the database creates a new table the name being based on the primary ID from one of the rows from the table "Controllers" to which the event relates to. Thus for example a Table "Alarm212" is created (the 212 is one of the primary ID's in the Table "Controllers") Is it possible and what would such a php statement be so that when viewing the data in the Table "Controllers" on a Web Page the php function is run for a particular row when a button is clicked, which then runs the php based on the "Controllers" primary ID in that particular row so it finds and the appropriate Table and then displays the info from this Table "Alarms212" , etc... New tables, Alarms 213, Alarms 214, are continually being added to the database. Any guidence will be appreciated.

hi there, i have the following query, which is supposed to return the valid sales lead counts and average the costs and count the leads during the past 30 days.

Hi all GURU's, I have a problem with UTF-8 characters when I post values/data from my MySQL database into the OPTIONs that I use when using a SELECT in my FORM. The PHP script files are in format UTF-8. The database, the tables and the columns are all set in UTF-8. The charset in the META-tag for the html output is set to UTF-8. All other text that is fetched from the database shows my characters (Swedish å ä ö) the right and correct way, EXCEPT when I echo the data in the OPTIONs in my SELECT box. What can I do? Sincerely, Andreas

I have been working on a code for a blog from scratch and now I have gotten the code to not throw errors but it is also not returning results. In this blog post I have created tags that can be attached to each blog post for easy reference. I have created a count of the tags on the right hand side which gives the name and a count for how many blog post use that tag. It is a link that you can click and the next step that I am having an issue with is just showing those blog post associated with that tag. I have written the code and as of right now is throwing no errors so I cannot look up how to fix it even though I have been working on it for hours. Here is the call that I am using once you click the link to pull up the results. blog_tags.php <?php include "includes.php"; $blogPosts = GetTaggedBlogPosts($_GET['tagId'], $DBH); foreach ($blogPosts as $post) { echo "<div class='post'>"; echo "<h2>" . $post->title . "</h2>"; $body = substr($post->post, 0, 300); echo "<p>" . nl2br($body) . "... <a href='post_view.php?id=" . $post->id . "'>View Full Post</a><br /></p>"; echo "<span class='footer'><strong>Posted By:</strong> " . $post->author . " <strong>Posted On:</strong> " . $post->datePosted . " <strong>Tags:</strong> " . $post->tags . "</span><br />"; echo "</div>"; } ?> Next is the function for displaying the link and counting the tags includes.php function getTagCount($DBH) { //Make the connection and grab all the tag's TAG TABLE HAS TWO FIELDS id and name $stmt = $DBH->query("SELECT * FROM tags"); $stmt->execute(); //For each row pulled do the following foreach ($stmt->fetchAll() as $row){ //set the tagId and tagName to the id and name fields from the tags table $tagId = $row['id']; $tagName = ucfirst($row['name']); //Next grab the list of used tags BLOG_POST_TAGS TABLE HAS TWO FILEDS blog_post_id and tag_id $stmt2 = $DBH->query("SELECT count(*) FROM blog_post_tags WHERE tag_id = " . $tagId); $stmt2->execute(); $tagCount = $stmt2->fetchColumn(); //Print the following list echo '<li><a href="blog_tags.php?tagId=' . $tagId . '"title="' . $tagName . '">' . $tagName . '(' . $tagCount . ')</a></li></form>'; //End of loop - start again } } This next part is the function used to pull and display the blog post. includes.php function GetTaggedBlogPosts($postTags, $DBH) { $stmt = $DBH->prepare("SELECT blog_post_id FROM blog_post_tags WHERE tag_id = :postTagId"); $stmt->bindParam(":postTagId", $postTags, PDO::PARAM_INT); $stmt->execute(); if(!empty($stmt)) { $blogstmt = $DBH->prepare("SELECT * FROM blog_post WHERE id = :blog_id ORDER BY id DESC"); $blogstmt->bindParam(":blog_id", $stmt, PDO::PARAM_INT); $blogstmt->execute(); } else { echo "Something went wrong....Please contact the administrator so that we can fix this issue."; } $postArray = array(); $result = $blogstmt->fetchAll(PDO::FETCH_ASSOC); foreach($result as $row){ $myPost = new BlogPost($row["id"], $row['title'], $row['post'], $row['author_id'], $row['date_posted'], $DBH); array_push($postArray, $myPost); } return $postArray; } Any ideas why it is not displaying?
