I'm developing a website for specific EVENTS. Each EVENT lasts for three months and has fixed start date and end date, and they repeat each year: Event 1: Jan. 1st – Mar. 31st Event 2: Apr. 1st – Jun. 30th Event 3: Jul. 1st – Sep. 30th Event 4: Oct. 1st – Dec. 31st I have two functions FUNCTION 1: should run 3 days before start of the event. FUNCTION 2: should run 1 day before start of last month of the event. Functions should execute only that specific event and not other future or past events. Here how the functions should run for each Event: Event 1: Jan. 1st – Mar. 31st Function 1: on Dec 29 Function 2: last day of Feb Event 2: Apr. 1st – Jun. 30th Function 1: on Mar 29 Function 2: last day of May Event 3: Jul. 1st – Sep. 30th Function 1: on Jun 28th Function 2: Last day of Aug Event 4: Oct. 1st – Dec. 31st Function 1: on Sept 28th Function 2: last day of Nov What I'm doing right now is checking today's date and comparing it to the event date. If event start date is > today and event start date < 3 then run function one. My problem/questions: As of now, I have to remember to execute the functions manually on a specific date. How can I make this automated? Can I execute the function using server Cron job? Will that be a good practice? How would you approach in checking the event date to today? I feel there maybe better way of checking the date to run the function instead of what I'm doing. I hope my question is not vague and makes sense. Thank you.

up votedown votefavorite I've been scraching my head for hours over this problem. I'm basically trying to fetch values from a loop inside a function to pass it to another foreach loop to get the desired results. And it is not working as I intend to. please, point me in the right direction. Here is the code: function ff($s) { $project=""; foreach ($s as $i=> $r ){ $r["friend_one"] == $_SESSION['uname'] ? $friends[]= $r["friend_two"] : $friends[] = $r["friend_one"]; $friend=$friends[$i]; $totalids=$project->totalids($_SESSION['uname'],$friend); } return $totalids; } $totalid= ff($f); print_r($totalid); foreach ($totalid as $v){ $id=$v['user_id']; //other logic to get desired result }

Hello! I'm starting to learn php and for practice I tried to resolve a simple exercise. the idea is to write a php function that inputs a tabe and returns +1 if positive numbers in the table are more than the negative ones. and return -1 if negative numbers in the table are more than the positive ones. 0 if they are equal. this is my code for the function starting from line 8 function plusmin ($tab) { $n = count($tab); $plus = 0; $min = 0; for ($i = 0; $i <= $n; $i++) { if ($tab[$i] > 0){ $plus++; } elseif ($tab[$i] < 0){ $min++; } } if ($plus > $min) { $result = "+1"; } elseif ($plus < $min) { $result = "-1"; } elseif ($plus == $min){ $result = "0"; } return $result; } and just to test it I created a table manually $tab[0] = 1; $tab[1] = -5; $tab[2] = -4; $tab[3] = 7; $tab[4] = -8; $tab[5] = -3; $tab[6] = 2; $tab[7] = 0; $tab[8] = -6; $tab[9] = -9; $k = plusmin($tab); echo $k; when I execute it It works, it shows for the case -1 but the browser shows this error Notice: Undefined offset: 10 in C:\Users\ahmed\PhpstormProjects\Exam 2013\tab.php on line 13 line 13 is this one if ($tab[$i] > 0){ Notice: Undefined offset: 10 in C:\Users\ahmed\PhpstormProjects\Exam 2013\tab.php on line 16 line 16 is this one elseif ($tab[$i] < 0){ I dunno what's the problem. and I know it will turn out to be a stupid problem but hey that's how we all learn. could anyone help? Thanks in advance

Hi all, I am trying to pass 4 variables from one php page to another php page containing a google maps api. The variables I am passing are geo coordinates. at the end I want to show the map on my php page however I am struggling with linking php and javascipt together. This is what I have so far: external function page: http://pastebin.com/NAKHmKxW [PART OF MAIN PHP PAGE] <div class="row"> <?php include_once("function_maps.php"); initMap($latitude, $longitude,$row['Latitude'],$row['Longitude']); ?> </div>

Hey friends, I just started learning php. I want to know the difference between == and === I exactly want to know the comment section of the given code below. Thanks. <?php $mystring = 'abc'; $findme = 'a'; $pos = strpos($mystring, $findme); // The !== operator can also be used. Using != would not work as expected // because the position of 'a' is 0. The statement (0 != false) evaluates // to false. if ($pos !== false) { echo "The string '$findme' was found in the string '$mystring'"; echo " and exists at position $pos"; } else { echo "The string '$findme' was not found in the string '$mystring'"; } ?>

Hi I am really struggling here i want this to check for fobidden words in an effort to stop sql injection. I cant seem to get it to work function secureit() { global $items_check; $unallowed = array('href', 'www', 'UPDATE', 'INSERT', 'DELETE', 'SET', 'OFFSET', 'ORDER BY', 'union', 'UPDATE', 'DROP TABLE', 'CREATE TABLE'); foreach($unallowed as $field) { if(stristr($items_check, $field) == TRUE) { $mess = 'NO Thanks "'.$items_check .'" is forbidden content!'; return $action = "0"; } } } The idea is that it checks the $items_check against a list of banned words if it finds one it doesnt allow the remaining script to execute.

Hi Folks, Firstly I am new, I have read several topics here and learned a lot, I would class myself as 'slightly better than basic', but my knowledge is mostly gained from reading code. I am making a simple POST form for work, the data gets inserted into MySQL, nice and easy, I can make it work if I write out the statement completely, BUT I need to make a new form, it will have HUNDREDS of input fields, I really don't want to write the code, and I figured programmatically is a good way to go anyway as forms change and new forms may be required, so I set about building a function to completely handle my post data, bind it to a statement and insert it into a table, I have scrapped it a half dozen times already because something fundamentally doesn't work, but I am very close! The function can write the statement, but I need to bind the POST values before I can insert, something going wrong here and I would appreciate some help, I have a feeling it's a problem with an array, but anyway I will show you what I have, give you some comments as to my reasoning, and hopefully you can help me with the last bit public function getColumnNames($table){ $sql = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE table_name = :table"; try { $stmt = $this->dbh->prepare($sql); $stmt->bindValue(':table', $table, PDO::PARAM_STR); $stmt->execute(); $output = array(); while($row = $stmt->fetch(PDO::FETCH_ASSOC)){ $output[] = $row['COLUMN_NAME']; } $all = array($output); $a1 = array_slice($output, 1); // I don't want column 1, it contains the ID, its auto incremented. $a2 = array_slice($a1, 0, -3); // I don't want the last 3 columns as they have default values $selected = array($a2); // contains all the columns except those excluded by array_slice, columns now match all of the input fields on the form foreach ($selected as $row){ $fields = "`" . implode('`, `', $row) . "`"; // I'm making `fields` here, $bind = ":" . implode(', :', $row); // And making :values here } return array ( "raw" => $all, "fields" => $fields, "bind" => $bind ); } catch(PDOException $pe) { trigger_error('Could not connect to MySQL database. ' . $pe->getMessage() , E_USER_ERROR); } } public function addRecord(){ $col = array(); $col = $this->getColumnNames("table"); $raw = array($col['raw']); $fields = array($col['fields']); $bind = array($col['bind']); $columnList = implode('`, `', $fields); $paramList = implode(', ', $bind); $sql = "INSERT INTO `{$this->dbtable}` ($columnList) VALUES ($paramList)"; return $sql; // this returns something like: INSERT INTO `table` (`field1`, `field2`, `field3`) VALUES (:field1, :field2, :field3)"; perfect I thought, now I just need to bind the values from $_POST... then I get stuck.

I' stuck with writing function for searching replaced numbers and would really appreciate if someone can tell me what I'm doing wrong. My table structure looks like: CREATE TABLE servis.zamjene_brojeva ( id INT(11) NOT NULL AUTO_INCREMENT, vrijeme TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, pocetni_broj VARCHAR(55) DEFAULT NULL, zamjenski_broj VARCHAR(55) DEFAULT NULL, glavni_broj VARCHAR(55) DEFAULT NULL, postoji_zamjena INT(1) DEFAULT NULL, PRIMARY KEY (id) ) My function looks like this: //funkcija za traženje zamjene brojeva function zamjena_broja($kataloski_broj){ //Traženje zamjenskog broja $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE glavni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $row = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row["zamjenski_broj"]; $broj_zamjena = mysql_num_rows($rezultat_zamjena); return $kataloski_broj; //Traženje druge zamjene broja if ($broj_zamjena <> 0) { $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE pocetni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $broj_zamjena2 = mysql_num_rows($rezultat_zamjena); $row2 = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row2["zamjenski_broj"]; return $kataloski_broj; //Traženje treće zamjene if ($broj_zamjena2 <> 0) { $upit_zamjena = "SELECT pocetni_broj, zamjenski_broj, glavni_broj FROM zamjene_brojeva WHERE pocetni_broj = '$kataloski_broj'"; $rezultat_zamjena = mysql_query($upit_zamjena) or die (mysql_error()); $broj_zamjena3 = mysql_num_rows($rezultat_zamjena); $row3 = mysql_fetch_array($rezultat_zamjena); $kataloski_broj = $row3["zamjenski_broj"]; return $kataloski_broj; } } } In pocetni_broj is old number and in glavni_broj is new number. But it can happen that number in glavni_broj is old and I need to search in pocetni_broj to see if there is even newer number and it can happen 5 or 6 times like that. I need to find all the numbers that are connected, but I'm not getting that. What am I doing wrong?

Hi everyone, I would like to know if: I have three different forms to create three different mysql codes. Now my code will generate the three mysql codes correctly but each time I tried to generate the second mysql code using another form, the previous will get wiped and therefore I can only have one mysql code working at the moment. (I apologize in advanced if my issue is not clearly stated.) Attached is the code that I have right now. I am trying to get all three mysql codes (Searchsql, Filtersql, Panelsql) correct so I can pass all three mysql queries to a function where it can combine all three queries into one array using the array_intersect function. Please kindly let me know your opinion on the problem and I would really appreciate the help. $object = new Three; class Three { public $Panel, $Search, $Filter; function save_Three() { while($Prow = sqli_fetch_array($Panel, MYSQLI_BOTH)) { $PanelName = $Prow ['name']; } while($Srow = sqli_fetch_array($Search, MYSQLI_BOTH)) { $SearchName = $Srow ['name']; } while($Frow = sqli_fetch_array($Filter, MYSQLI_BOTH)) { $FilterName = $Frow ['name']; } $Combined = array_intersect($Panel, $Search, $Filter); foreach ($Combined as $item) print $item; } } $Panelsql = "SELECT DISTINCT aID, name from test.article"; if (isset($_GET['pid'])) { $pID= $_GET['pid']; echo "$pID"; $Panelsql = "SELECT DISTINCT aID, name from test.a_m, test.platform, test.message, test.article where aid in (SELECT DISTINCT assocAID from test.a_m, test.platform, test.message where assocMID in (SELECT mID from test.message, test.platform where pID=$pID and pID = assocPID))"; } else if (isset($_GET['mid'])) { $mID= $_GET['mid']; $Panelsql = "SELECT DISTINCT aID, name from a_m, message, article where aid in (SELECT DISTINCT assocAID from a_m, message where mID=$mID and mID = assocMID)"; } else { $Panelsql = "SELECT DISTINCT aID, name from article"; } $object->Panel = $Panelsql; $aRegions = $_POST['RegionSelected']; $Filtersql = 'SELECT * FROM test.article'; if(isset($aRegions)) { $Filtersql .= ' WHERE 1 AND ('; foreach ($aRegions as $word) if($word==$aRegions[count($aRegions)-1]) { $Filtersql .= " Region = '". $word ."')"; } else { $Filtersql .= " Region = '". $word ."' OR"; } } //Population filtering function $aPopulations = $_POST['PopulationSelected']; if(isset($aPopulations)) { if(!isset($aRegions)){$Filtersql .= ' WHERE 1 AND ('; } else { $Filtersql .= ' AND ('; } foreach ($aPopulations as $word) if($word==$aPopulations[count($aPopulations)-1]) { $Filtersql .= " Population = '". $word ."')"; } else { $Filtersql .= " Population = '". $word ."' OR"; } } $object->Filter = $Filtersql; $Searchsql="SELECT * FROM test.article"; if (isset($_POST['search'])){ $st= ($_POST['search_box']); $Searchsql .= " WHERE name LIKE '%{$st}%' OR abstract LIKE '%{$st}%' OR Summary LIKE '%{$st}%' OR Keyword LIKE '%{$st}%' OR population LIKE '%{$st}%'OR region LIKE '%{$st}%'"; } $object->Search = $Searchsql;

I have included language file and function file in my index.php include 'includes/functions.php'; include 'languages/english.php'; english.php contains <?php $lang['success']['a'] = 'Settings have been updated.'; $lang['error']['b'] = 'Database error. Please try again later!'; ................................. ?> functions.php <?php function testFunction($id, $settings, $db){ $query = 'UPDATE table_name SET a = a + :a WHERE id = :id'; $update = $db->prepare($query); $update->bindParam(':a', $settings['a'], PDO::PARAM_INT); $update->bindParam(':id', $id, PDO::PARAM_INT); $success = $update->execute(); if($success){ print $lang['success']['a']; }else{ print $lang['error']['b']; } } ................................................. ?> Now if i print testFunction(); i got Undefined variable: lang in ............. If i include 'languages/english.php'; in testFunction() then everything works. Any other way to make $lang working without including language file in testFunction(). (Sorry for my bad english) print testfunction(2, $settings, $db);

What's wrong with this simple script to call 2 functions: if (up < max){ lower.onclick=min_function; } else if (up > min) { lower.onclick=max_function; }

Hi everyone. I am using Wordpress and have a calendar plugin I'm using to display events. I'm trying to get the output of a function to display differently in one of my templates (have the output on one line). By default the plugin is having the output appear on multiple lines. Is it possible to wrap the function in a div to target it and remove the line breaks? I haven't been able to find anything to force the output to be on a single line. I'm not sure if I'm doing something wrong since I'm a newbie at this, or if I'd need to use something else other than CSS since the function does use a class, as shown here in the plugin's docs. Any advice or tips would be grealty appreciated, as I'm really lost right now. Thanks for taking the time to read this, and of course, for any assistance! Sean This is what I've added to my template thus far: <div class="tribe-events-event-category-list"> <?php echo Tribe_Register_Meta::event_category( 'tribe_event_category' ) ?> </div> Here are a couple images of how the output is being displayed by default (on two lines). Again, I don't want to change the output everywhere on my site; only on a certain php template.

Hello All, I am trying to turn a PHP application I made about a year ago into a WordPress plugin. I'm reasonably new in the world of WordPress plugins and have what I think will be a simple question. My plugin creates a shortcode, and when the WordPress page with that short code on is loaded, the program calls a function and displays it. My question is, within that function, how do I create a link or button (or something else) which will run the chosen function. Here is what I mean: function welcome() { ?>Welcome. This is the first screen of the plugin. Click <a href="???">here</a> to register. } function register() { register here } How would I make the above piece of code work. My thanks in advance.

I need help with my code. I'm trying to make it so that when I hit the withdraw button the money is withdrawn and the new amount is shown in the text box. As of now, when I hit the money buttons the money is withdrawn. The withdraw button does nothing. I can't figure out what I did wrong. assignment7.html

Hi there i have recently started working with php so I will probably be a familiar name around here. I have been giving a task that I have got a bit stuck with. To give a brief overview I have products that are stocked in x number of warehouses, when a customer places an order depending on their location I will ship from the warehouse that is closest to them if it has all products in stock. I have the following two arrays The first represents a customers order containing the id of the product and the quantity they have selected. e.g. product id:35659, qty:1 Array ( [35659] => 1 [35699] => 1 [35734] => 2 ) The second array shows the quantity in stock for each product in each 3 warehouses that stock it e.g. 35659 being the product id, [9][114][126] being the warehouse and 10,1,0 being the quantity of stock for that item in the warehouse. Array ( [35659] => Array ( [9] => 10 [114] => 1 [126] => 0 ) [35699] => Array ( [9] => 8 [114] => 0 [126] => 5 ) [35734] => Array ( [9] => 10 [114] => 0 [126] => 0 ) ) function check_warehouse_stock($order=array(), $stock=array(), $warehouse=0) { foreach($order as $id => $qty) if($stock[$id][$warehouse] < $qty) return false; return true; } // $warehouses is an array of my warehouses already in their preference order foreach($warehouses as $w) { if(check_warehouse_stock($order, $stock, $w)) break; $w = false; } // $w is now the first warehouse with all the stock, or false if no warehouses have any stock So far I have got the above code which loops through each warehouse and goes into a function that checks each item in their order and sees if any item in their basket is below the quantity in the warehouse, if no items is below the quantity it returns true and that is the first warehouse with all items in stock, if no warehouse has all items in stock it returns false. This is where I am getting stuck, if no warehouse has all items in stock I need to go into a similar function and have some sort of rule that checks if no one warehouse has all products in stock I will ship from wherever has each product in stock starting with the closest and so on... e.g. if the first warehouse had 2 of the 3 items in stock and the second warehouse had 1 in stock we would ship 2 products from the first and 1 from the second. Any help would be greatly appreciated, even with just the logic on how to approach this. Thanks

Hello! Second post here. I'm new to PHP and have an idea of what needs to be done, but im not sure the best way to impliment it. Basically im looking for direction on whether I should use JS, AJAX, Jquery, or something else. from browsing around im guessing its going to be a combination of AJAX and Jquery to get this accomplished. Please advise on the best method to acomplish this. Thanks =) The user needs to populate txtAddr and hit btnGen. The function will then confirm txtAddr is equal to a variable. If it is equal, populate other 2 text fields (txtKey & txtDest) with predefined variables. <form action="frmGen" method="post"> <input name="txtAddr" type="text"> <!-- User enters text here -- Confirm txtAddr.text = $VarAddr -- If True, continue. If False, display DIV message --> <input name="txtDest" type="text"> <!-- Text field is filled with value from server/SQL when btnGen is pressed--> <input name="txtKey" type="text"> <!-- Text field is filled with value from server/SQL when btnGen is pressed--> <input name="btnGen" type="button"> <!-- assuming txtAddr is True, display strings in 2 text fields above & store all values from 3 text boxes in SQL --> </form>

I am trying to create a script (from a tutorial I try to adapt to my own needs) and I am running into a few problems. Here I go... I have an /includes folder which contains the following: database.php and functions.php with the following content: database.php <?php // Database connectivity stuff $host = "localhost"; // Hostname for the database. Usually localhost $username = "root"; // Username used to connect to the database $password = "root"; // Password for the username used to connect to the database $database = "blog"; // The database used // Connect to the database using mysqli_connect $connection = mysqli_connect($host, $username, $password, $database); // Check the connection for errors if (mysqli_connect_errno($connection)) { // Stop the whole page from loading if errors occur die("<br />Could not connect to the database. Please check the settings and try again.") . mysqli_connect_error() . mysqli_connect_errno(); } ?> functions.php <?php // Functions file for the system function show_posts($user_id) { $posts = array(); $sql = "SELECT body, stamp from posts where user_id = '$user_id' order by stamp desc"; $result = mysqli_query($connection, $sql); while ($data = mysqli_fetch_assoc($result)) { $posts = array( 'stamp' => $data->stamp, 'user_id' => $user_id, 'body' => $data->body ); } return $posts; } function show_users() { $users = array(); $sql = "SELECT id, username FROM users WHERE status = 'active' ORDER BY username"; $result = mysqli_query($connection, $sql); while ($data = mysqli_fetch_array($result)) { $users[$data->id] = $data->username; } return $users; } function following($user_id) { $users = array(); $sql = "SELECT DISTINCT user_id FROM following WHERE follower_id = $user_id"; $result = mysqli_query($connection, $sql); while ($data = mysqli_fetch_assoc($result)) { array_push($users, $data->user_id); } return $users; } ?> And here's the code that I run to display the users in users.php <?php $users = show_users(); foreach ($users as $key => $value) { echo $key . " " . $value; } ?> That throws me the following errors: Notice: Undefined variable: connection in /Applications/MAMP/htdocs/blog/includes/functions.php on line 22 Warning: mysqli_query() expects parameter 1 to be mysqli, null given in /Applications/MAMP/htdocs/blog/includes/functions.php on line 22 Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in /Applications/MAMP/htdocs/blog/includes/functions.php on line 24 I've tried to pass the $connection value to the show_users(); function with no results... any help would be appreciated. I am able to display the users from the database if I introduce the following code in users.php, but I want to try and keep things as clear as possible, without cluttering the files unnecessary. <?php $users = array(); $query = "SELECT id, username FROM users WHERE status = 'active' ORDER BY username"; $result = mysqli_query($connection, $query); if ($result) { while ($member = mysqli_fetch_assoc($result)) { echo strip_tags($member['username']) . "<br />"; } } else { echo "There are no posts to display. Why not add a new one?"; } mysqli_free_result($result); mysqli_close($connection); ?> PS: The users.php file also has require('includes/database.php'); and require('includes/functions.php'). I guess I'm trying to recreate the last bit of code into a working function... and I can't seem to do it. Any help is appreciated. I hope it makes an sense... -- Andrei

So this is my 2nd PHP class ever. And this right here is part of my final. I'm sure you all know what the "shuffle" function does.

Hi guys, I am trying to understand these questions regarding function and how or where can i get some knowledge to understand and create the code. questions are: 1. Open the text file “status.txt” as read only using variable $handle to store the file handle. 2. Begin a session. (what does it mean begin session? does it mean start using the if condition?) 3. Return the number of elements in array $days. 4. Convert an array $data with five elements into a string that is delimited by tab. (what does it mean by delimited by tab?) 5. Check if the form text item "status" obtained via get method is empty. Thank you in advance!
