  2. Hello everyone, I am trying to submit a comment in a comment box and send it to the DB but is not happening. The connection is good as I am logging in and all but no data is sent to the DB when I post the comment. It doesn't show in my comment section either. Form <!--comment section--> <?php if(isset($_SESSION['id'])) { echo "<form method='POST' action='" . setComments($conn) . "'> <input type='hidden' name='uidUsers' value='".$_SESSION['id']."'> <input type='hidden' name='posted' value='" . date('Y-m-d H:i:s') . "'> Comments: <textarea rows = '5' cols = '15' name='body'></textarea><br><br> <button name='commentSubmit' type='submit'>Comment</button> </form>"; }else { echo "Log in to comment!"; } getComments($conn); Function to set and get comments function setComments($conn) { if (isset($_POST['commentSubmit'])){ $user_id = $_POST['uidUsers']; $body = $_POST['body']; $posted = $_POST['posted']; $sql = "INSERT INTO comments (uidUsers, posted, body) VALUES ('$user_id', '$posted', '$body')"; $result = mysqli_query($conn, $sql); } } function getComments($conn) { $sql = "SELECT * FROM comments"; $result = mysqli_query($conn, $sql); while ($row = $result->fetch_assoc()){ $id = $row['uidUsers']; $sql2 ="SELECT * FROM users WHERE uidUsers='$id'"; $result2 = mysqli_query($conn, $sql2); if($row2 = $result2->fetch_assoc()){ echo "<div class='comment-box'><p>"; echo $row2['uidUsers'] .

  4. Hi, I am making a CMS and I can't get the search page to work right. The CMS is for a new local DJI store and I can't get anything to show up when I search for those who have paid for insurance on their drones. And when I enter a first or last name that multiple people have in common, like Mike or Smith, the info doesn't display correctly, The first customer is displayed correctly, but no one else is. searchcodefirst.php searchcodeinsurance.php searchcodelast.php
  5. Hi everyone, I'm having troubles with query from database. I want to select all from one table and select sum from second table in the same time. Is this possible? Here is my script: $conn = mysqli_connect('localhost', 'root', '', 'test'); if (!mysqli_set_charset($conn, "utf8")) { printf("Error loading character set utf8: %s\n", mysqli_error($conn)); } $sql = "SELECT first_id, first_name FROM first"; $sql = "SELECT sum(total) as SumTotal FROM second"; $result = mysqli_query($conn, $sql); while ($data = mysqli_fetch_array($result)) { echo '<tr>'; echo '<th>'.$data['first_id'].'</th>'; echo '<th>'.$data['first_name'].'</th>'; echo '<th>'.$data['SumTotal'].'</th>'; echo '</tr>'; } mysqli_close($conn); Thanks!
  6. If anyone could help, I'm not getting an error message and I've tried changing the code around a few times and outputting errors.

  8. Hello guys. I got a problem that whenever you register on my page, the registration is successful, no errors, successful redirection to login page, but the registration does not write the information into database and I have no idea why... I'm sure that i'm connecting correctly, to the correct table, with the correct commands, but it kinda does not work... BTW (This registration and login and all worked a few weeks ago, but I got an sudden internal server error, so I had to delete and reupload all files, and I had to change database. I changed the database, created the same table with the same columns, also I overwrote ALL old database information to the new (password, dbname,name) and, so page works fine, but that registration does not...I'm including my code for registration and registration form) Registration process CODE: <?php include_once 'db_connect.php'; include_once 'psl-config.php'; $error_msg = ""; if (isset($_POST['username'], $_POST['email'], $_POST['p'])) { // Sanitize and validate the data passed in $username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING); $email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL); $email = filter_var($email, FILTER_VALIDATE_EMAIL); if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { // Not a valid email $error_msg .= '<p class="error">The email address you entered is not valid</p>'; } $password = filter_input(INPUT_POST, 'p', FILTER_SANITIZE_STRING); // Username validity and password validity have been checked client side. // This should should be adequate as nobody gains any advantage from // breaking these rules. // $prep_stmt = "SELECT id FROM members WHERE email = ?

  9. 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 = $stmt->get_result();
  10. Not sure what is going on I tried everything (well, that I could think of) . . . any ideas are welcome (hopefully new ones - getting frustrated :/) if ($mysqli->prepare("INSERT INTO solcontest_entries (title, image,content, user, contest) VALUES ($title, $image, $content, $userid, $contest")) { $stmt2 = $mysqli->prepare("INSERT INTO `solcontest_entries` (title, image, content, user, contest) VALUES (?, ?, ?, ?, ?)"); $stmt2->bind_param('sssss', $title, $image, $content, $userid, $contest); $stmt2->execute(); $stmt2->store_result(); $stmt2->fetch(); $stmt2->close(); } else { die(mysqli_error($mysqli)); } Error I get from die mysqli_error: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' of the site's lead ad, user_61609201, contest_1' at line 1" I have also tried $mysqli->query no change occured. I added the "if else die" statement because it was giving no errors, but not adding it to the database. It gives the error where $content is supposed to be inserted. Various combos and singles I tried for the variable: //$content = cleansafely($_POST['content']); //$content = mysqli_real_escape_string ($mysqli, $_POST['content']); //$content = cleansafely($content); $content = $_POST['content']; If any more information is needed please let me know.
  11. Hi guys, I am trying to display data to a user who submitted it. So, user A submits data to the db and also user B. I want it so that user A cannot see user B's data but only the data they have submitted. Hope that makes sense. Here is the code along with the table of data to be displayed. <div class="panel-body"> <div class="table-responsive"> <table class="table table-striped table-bordered table-hover" id="bookings_table"> <thead> <tr> <th class="text-center">Issue ID</th> <th class="text-center">Driver Name</th> <th class="text-center">Date Submitted</th> <th class="text-center">Fleet Number</th> <th class="text-center">Issue</th> <th class="text-center">Description</th> <th class="text-center">Priority</th> <th class="text-center">Status</th> </tr> </thead> <tbody> <?php $check = isset($_SESSION['username']); if($stmt = $link -> prepare("SELECT issue_id, driver_name, submit_date, fleet_number, issue_name, issue_description, issue_priority, issue_status FROM maintenance_requests WHERE username = ?")) { $stmt -> execute(); $stmt -> bind_result($issue_id, $driver_name, $submit_date, $fleet_number, $issue_name, $issue_description, $issue_priority, $issue_status); while($stmt->fetch()) { ?> <tr class="odd gradeX"> <td class="text-center"><?php echo $issue_id; ?></td> <td class="text-center"><?php echo $driver_name; ?></td> <td class="text-center"><?php echo $submit_date; ?></td> <td class="text-center"><?php echo $fleet_number; ?></td> <td class="text-center"><?php echo $issue_name; ?></td> <td class="text-center"><?php echo $issue_description; ?></td> <td class="text-center"><?php echo $issue_priority; ?></td> <?php if($issue_status == "Pending") { ?> <td class="text-center warning"><?php echo $issue_status;?></td> <?php }else if($issue_status == "Open"){ ?> <td class="text-center danger"><?php echo $issue_status; ?></td> <?php }else if($issue_status == "Repaired"){ ?> <td class="text-center success"><?php echo $issue_status ;} ?></td> </tr> <?php } $stmt -> close(); } mysqli_close($link); ?> If I remove the WHERE clause, it displays data from both users. Placing the WHERE clause shows no data. Can someone have a look and see where I am going wrong and maybe point me in the right direction? Many thanks in advance.
  12. $results = mysql_query("$select", $link_id); while ($query_data = mysql_fetch_row($results)) { $link_id = mysqli_connect("$db_host","$db_user","$db_password","$db_database"); if ($mysqli->connect_errno) { echo "Failed to connect to MySQL: (" . $mysqli->connect_errno .

  13. I am updating all my code from mysql to mysqli. Currently using PHP 5.4 but will update to 5.5 once all this updating is done. Anyway, I have this old function for making data safe for inserting into mysql database. I changed all instances of "mysql" to "mysqli"... function mysqli_prep($value) { $magic_quotes_active = get_magic_quotes_gpc(); $new_enough_php = function_exists("mysqli_real_escape_string") ; //i.e. PHP >= v4.3.0 if($new_enough_php) { //PHP v4.3.0 or higher //undo any magic quote effects so mysqli_real_escape_string can do the work if($magic_quotes_active) { $value = stripslashes($value) ;} $value = mysqli_real_escape_string($connection, $value); } else { //before php v4.3.0 // if magic quotes aren;t already on then add slashes manually if(!magic_quotes_active) { $value = addslashes($value); } // if magic quotes are active, then the slashes already exist } return $value; } When I load that page that calls this function, I get... Warning: mysqli_real_escape_string() expects parameter 1 to be mysqli, null given in (mypath) This is my $connection by the way, which works fine on other pages that need it... $connection = mysqli_connect('localhost', 'myusername', 'mypassword', 'mytable'); if (!$connection) { die("database connection failed: " . mysqli_error()); } Any ideas what I'm doing wrong?
  14. I have the following general mySQL query: $query = sprintf( "SELECT a.A, a.B, ..., a.C, FROM a WHERE a.A = %s ORDER by a.A;", implode(" OR a.A = ", $_SESSION['values'])); for some records, B has a value, and for others, B is NULL. That is what I want. I extract the query with the following PHP: for ($i = 0; $i < $nrows; $i++){ $row = mysqli_fetch_assoc($result);//fetches data stored within each row extract($row); echo "<tr>"; foreach($row as $column => $field){ if($field == $...){ ... } elseif($field == $C){ echo"<td> <input type='text' name='C+[]' value='$C'> </td>"; } echo "</tr>" } In the resulting html table, records containing not null B fields are presented accurately, while records with null B fields incur a duplication of field C. This offset occurs at the beginning of the record, pushing the final field in the record outside the table boundaries. I think I've narrowed down the problem to the extract() function, as r_print readouts of every other variable in the script returns the accurate field names and values. But, running print_r on $row after extract() provides an identical printout to other variables in the script. What are some possible ways I can stop the duplication of field C from occurring? Happy to provide more information upon request.
  15. Me again.. I've struggled for the past 2 hours to insert article comments and link them to an existent article on the page. Now, the function that is displaying both comments and articles looks like this: function list_articles() { include('core/db/db_connection.php'); $sql = "SELECT blog.content_id, blog.title, blog.content, blog.posted_by, blog.date, article_comments.comments, article_comments.comment_by FROM blog LEFT OUTER JOIN article_comments ON blog.content_id = article_comments.blog_id WHERE blog.content != '' ORDER BY blog.content_id DESC"; $result = mysqli_query($dbCon, $sql); $previous_blog_id = 0; while ($row = mysqli_fetch_array($result)) { if ($previous_blog_id != $row['content_id']) { echo "<h5 class='posted_by'>Posted by {$row['posted_by']} on {$row['date']}</h5> <h1 class='content_headers'>{$row['title']}</h1> <article>{$row['content']}</article> <hr class='artline'>"; $previous_blog_id = $row['content_id']; } if (!empty($row['comment_by']) && !empty($row['comments'])) { echo "<div class='commented_by'>Posted by: {$row['comment_by']} </div> <div class='comments'>Comments: {$row['comments']}</div> <hr class='artline2'>"; } } } The function I'm running to insert comments into article_comments table function insert_comments($comments, $comment_by, $blog_id) { include('core/db/db_connection.php'); $comment_by = sanitize($comment_by); $comments = sanitize($comments); $sql = "INSERT INTO article_comments (comments, comment_by, blog_id) VALUES ('$comments', '$comment_by', '$blog_id')"; mysqli_query($dbCon, $sql); } This works - it does the insertion, however I have no clue on how I could target the $blog_id variable when the user submits the post... The below is the form I use <?php echo list_articles(); if (!empty($_POST)) { insert_comments($_POST['comments'], $_POST['username'], 11); } ?> <form method='post' action='' class='comments_form'> <input type='text' name='username' placeholder='your name... *' id='name'> <textarea name='comments' id='textarea' placeholder='your comment... *' cols='30' rows='6'></textarea> <input type='submit' name='submit' id='post' value='post'> </form> I bet you noticed that I've manually inserted 11 as a param for the last variable. This links to blog_id 11 (the foreign key) in my article_comments table. It is displaying the comment just fine. Is there any way to target $blog_id without having to insert a number manually? Something like how I am targeting the $comments variable using $_POST['comments'] ? Also, even if I can target that, how do I know which post is the user commenting to? Should I give them the option to choose in a drop-down list ? That seems awkward.. but it's the only solution I can think of.
  16. Hi All, I get the following message when running a multiline query through mysqli. Here is my simplified code : $sql='SELECT CURRENT_USER();'; $sql.='SELECT CURRENT_time();'; $rs = @mysqli_multi_query($link,$sql); if (!$rs) { } else { do { if ($rs = mysqli_store_result($link)) { while ($row = mysqli_fetch_row($rs)) { echo "<br/> ". $row[0]; } mysqli_free_result($rs); } if (mysqli_more_results($link)) { echo "<br/>-----------------<br/>"; } } while (mysqli_next_result($link)); } If I use "while (mysqli_next_result($link) && mysqli_more_results($link));" instead of "while (mysqli_next_result($link))", I get no error message, but the current time (returned by the second query) won't display. Thanks for your help!
  17. I am trying to add a query to my script that updates a value in my database by subtracting "1".

  18. Hello my good people I'm doing a content manager system in PHP and mySQLi, following a serie of video tutorials. But in my project I am using a tree menu.

  19. Hi guys and Gals, This has my head wrecked to be honest. I am trying to upload an image to a directory, which is working. However, I also want to put the file name into MySQL. This will work if the image upload script is removed. With the script enabled, the file uploads but I get "Undefined index: userPic" from the following line: $userPic = mysqli_real_escape_string($mysqli, $_POST['userPic']); Here is the complete code: if(isset($_POST['Submit'])){//if the submit button is clicked $company_name = mysqli_real_escape_string($mysqli, $_POST['company_name']); $company_abn = mysqli_real_escape_string($mysqli, $_POST['company_abn']); $company_email = mysqli_real_escape_string($mysqli, $_POST['company_email']); $address = mysqli_real_escape_string($mysqli, $_POST['address']); $company_phone = mysqli_real_escape_string($mysqli, $_POST['company_phone']); $company_slogan = mysqli_real_escape_string($mysqli, $_POST['company_slogan']); $userPic = mysqli_real_escape_string($mysqli, $_POST['userPic']); // Upload Image if (isset($_FILES["userPic"]["name"])) { $name = $_FILES["userPic"]["name"]; $tmp_name = $_FILES['userPic']['tmp_name']; $error = $_FILES['userPic']['error']; if (!empty($name)) { $location = 'uploads/'; if (move_uploaded_file($tmp_name, $location.$name)){ echo 'Uploaded'; } } else { echo 'please choose a file'; } } $sql="UPDATE company_settings SET company_name='$company_name', company_slogan='$company_slogan', company_abn='$company_abn', company_email='$company_email', address='$address', company_phone='$company_phone', userPic='$userPic'"; $mysqli->query($sql) or die("Cannot update");//update or error } Has anyone got any ideas where I am going wrong (besides not using PDO) and how I can solve it? Thanks in advance.
  20. how i can make a insert using this fuctions I m learning php, as using this functions (mysqli abstract) but after update wont work any more. /** insert data array */ public function insert(array $arr) { if ($arr) { $q = $this->make_insert_query($arr); $return = $this->modifying_query($q); $this->autoreset(); return $return; } else { $this->autoreset(); return false; } } complement /** insert query constructor */ protected function make_insert_query($data) { $this->get_table_info(); $this->set_field_types(); if (!is_array(reset($data))) { $data = array($data); } $keys = array(); $values = array(); $keys_set = false; foreach ($data as $data_key => $data_item) { $values[$data_key] = array(); $fdata = $this->parse_field_names($data); foreach ($fdata as $key => $val) { if (!$keys_set) { if (isset($this->field_type[$key])) { $keys[] = '`' . $val['table'] . '`.`' . $val['field'] . '`'; } else { $keys[] = '`' . $val['field'] . '`'; } } $values[$data_key][] = $this->escape($val['value'], $this->is_noquotes($key), $this->field_type($key), $this->is_null($key), $this->is_bit($key)); } $keys_set = true; $values[$data_key] = '(' . implode(',', $values[$data_key]) . ')'; } $ignore = $this->ignore ? ' IGNORE' : ''; $delayed = $this->delayed ? ' DELAYED' : ''; $query = 'INSERT' . $ignore . $delayed . ' INTO `' . $this->table . '` (' . implode(',', $keys) . ') VALUES ' . implode(',', $values); return $query; } before update this class i used to insert data like this $db = Sdba::table('users'); $data = array('name'=>'adam'); $db->insert($data); this method of insert dont works on new class. if i try like this i got empty columns and empty values. thanks for any help complete class download http://goo.gl/GK3s4E
  21. I need urgent help! For two days I've been trying to find the source code to upload image to database and display, after trying all the codes I kept getting all sorts of errors. I'm using phpmyadmin. Fatal error: Call to undefined function finfo_open() in C:\xampp\htdocs\geology\file_insert.php on line 51 Second help needed is to display or restrict 3 latest posts only. I want to display only 3 latest posts sort by latest date posted. I'm not sure how to loop this through. Another thing is, when the user clicks on the title of a specific article, a new window will appear to display only the data that belong to it (Title, Publisher, Content...) For example, there are 3 articles (rock, mineral, salt) user clicks on Rocks, a new window appear showing all Rocks info. <?php $sql = "select * from article ORDER by article_postdate DESC"; $result = mysqli_query($conn, $sql); while($row = mysqli_fetch_assoc($result)) { ?> <h3><a href="#"><?php echo $row["article_title"]; ?></a></h3> <p class="byline"><span><?php echo $row["article_postdate"]; ?><br> Published By:<?php echo $row["author_id"]; ?></p></a></span></p> <p><?php echo $row["article_details"]; ?></p> <td><a href = "edit.php?article_id=<?php echo $row['article_id']; ?>">More...</a></td> <?php } ?>
  22. Hi I'm using php file to retrieve the amount of records in my database, but all of a sudden I get 0 results. It worked fine a few days ago. I got PHP 5.2.* on my host. Here is the current script that I use. Did I made a mistake somewhere? <?php $con=mysqli_connect("******","*****","*****","****"); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } $sql="SELECT * FROM mxit"; if ($result=mysqli_query($con,$sql)) { $rowcount=mysqli_num_rows($result); //printf("Result set has %d rows.\n",$rowcount); // Free result set mysqli_free_result($result); } mysqli_close($con); ?>
  23. I created a recipe site that displays various dishes, and I'm tickled pink that I got it to work (first time doing this!) But I'd like to have pages that displays dishes by its category. The column that houses this is called "category" which has 7 total: Appetizers & Beverages, Soups & Salads, Side Items, Main Dishes, Baked Goods, Desserts, and Cookies & Candy. I have this page connected to a "connection.php" page, but here's the code in question: <!-- Page Title--> <div class="row"> <div class="col-lg-12"> <h1 class="page-header">Appetizers & Beverages</h1> </div> </div> <!-- /Page Title --> <!-- Displayed Data--> <?php $sql = "SELECT id, category, bilde, title FROM oppskrift_table ORDER BY title "; $result = mysqli_query($con, $sql); if(mysqli_num_rows($result) > 0 ){ while($row = mysqli_fetch_assoc($result)){ ?> <div align="center" class="col-md-3"> <a href="#"> <img class="img-responsive img-cat" src="bilder/rBilder/<?=$row['bilde']?>" width="250" alt=""> </a> <h4 style="max-width:250px;"> <a href="#" class="dishes"> <?=$row['title']?> </a> </h4> </div> <?php } } ?> <!-- END Displayed Data--> </div> How can I tweak this so that only the category Appetizers & Beverages shows up on the page?
  24. can someone assistance me with converting this code over to mysqli. I know that mysqli requires 2 parameters instead of one... i tried $user = mysqli_real_escape_string($g_link, $en['user']); but no connection was passed. $user = mysql_real_escape_string($en['user']); $pass = mysql_real_escape_string($en['pass']); $sql = "SELECT m_id, m_user, m_pass, m_email, m_del FROM $membtable WHERE m_user='".$user."' AND m_pass='".$pass."' AND m_del!=1"; $result = mysql_query($sql); $line = mysql_fetch_assoc($result); Db Connection $g_link = false; function GetDbConn() { global $g_link; if( $g_link ) return $g_link; $g_link = mysqli_connect($db_server, $db_user, $db_pass) or die("Error " . mysqli_error($g_link)); mysqli_select_db($g_link, 'cialdb') or die('Could not select database.'); return $g_link; }
  25. I'm a beginner here and i am learning the basic in converting from MySQL to MySQLi. I am currently working on this registration page which I would want to convert to MySQLi. Please advise me how to modify this script, I would prefer the procedural style. The MySQLi coding is not working because it would notg insert into the database like the MySQL coding would, would appreciate if your can help me.
