  • A self-creator: What pattern is this? php

    - by user151841
    I have several classes that are basically interfaces to database rows. Since the class assumes that a row already exists ( __construct expects a field value ), there is a public static function that allows creation of the row and returns an instance of the class. Here's a pseudo-code example : class fruit { public $id; public function __construct( $id ) { $this->id = $id; $sql = "SELECT * FROM Fruits WHERE id = $id"; ... $this->arrFieldValues[$field] = $row[$value]; } public function __get( $var ) { return $this->arrFieldValues[$var]; } public function __set( $var, $val ) { $sql = "UPDATE fruits SET $var = $val WHERE id = $this->id"; } public static function create( $id ) { $sql = "INSERT INTO Fruits ( fruit_name ) VALUE ( '$fruit' )"; $id = mysql_insert_id(); $fruit = & new fruit($id); return $fruit; } } $obj1 = fruit::create( "apple" ); $obj2 = & new fruit( 12 ); What is this pattern called? Edit: I changed the example to one that has more database-interface functionality. For most of the time, this kind of class would be instantiated normally, through __construct(). But sometimes when you need to create a new row first, you would call create().

    - by user547794
    Hello, I am trying to use this query to return every instance where the variable $d['userID'] is equal to the User ID in a separate table, and then echo the username tied to that user ID. Here's what I have so far: $uid = $d['userID']; $result = mysql_query("SELECT u.username FROM users u LEFT JOIN comments c ON c.userID = u.id WHERE u.id = $uid;")$row = mysql_fetch_assoc($result); echo $row['username'];

  • Thumbnailing and then Saving as a Blob with PHP in Wordpress

    - by Parris
    The below code seems like it should work; however, the blob in the database only contains 0 after the function is run. Does the below code look accurate? If not how can I fix it? $tmpName = $_FILES['picture']['tmp_name']; $fp = fopen($tmpName, 'r'); $binary = fread($fp, filesize($tmpName)); fclose($fp); $originalImage = imagecreatefromstring($binary); $tempImage = imagecreate(100,100); imagecopyresized($tempImage,$originalImage,0,0,0,0,100,100); ob_start(); imageJPEG($tempImage); $thumbnail = ob_get_contents(); ob_end_clean(); $wpdb->query("UPDATE ".$wpdb->prefix."items SET picture = $thumbnail WHERE id=$id'"); Thank :)!

  • How to implement callback functions inside classes (PHP)

    - by sombe
    I need to use a class callback method on an array inside another method (the callback function belongs to the class). class Database { public function escape_string_for_db($string){ return mysql_real_escape_string($string); } public function escape_all_array($array){ return array_filter($array,"$this->escape_string_for_db"); } } Is this the right way to go about that? (I mean, in terms of the second parameter passed to array_filter)

  • MySQL Table Loop using PHP

    - by JM4
    I have an online form which collects consumer data and stores in a dedicated MySQL database. In some instances, data is passed in the URL under the "RefID" variable which is also stored in the database and attached to each registration. I use the 'mysql_num_rows ($result)' to fetch all agent details on another page but this only returns ALL available details. My goal is as follows: GOAL I want to create an HTML table in which rows are automatically generated based on the list of all registrations on my site. A new row is created IF and ONLY IF a unique RefID is present on that particular record. In the event the field is NULL, it is reported on a single line. In short, the HTML table could look something like this: RefID - Number of Enrollments abc123 - 10 baseball - 11 twonk - 7 NULL - 33 Where abc123 is a particular RefID and 10 is the number of times that RefID appears in the DB. If a new registration comes in with RefID = "horses", a new row is created, showing "horses - 1". The HTML table will be viewable by account administrators needing to see the number of enrollments for a particular RefID (which they won't know ahead of time). Anybody have any suggestions?

  • Strange PHP array behavior overwriting values with all the same values

    - by dasdas
    Im doing a simple mysqli query with code ive used many times before but have never had this problem happen to me. I am grabbing an entire table with an unknown number of columns (it changes often so i dont know the exact value, nor the column names). I have some code that uses metadata to grab everything and stick it in an array. This all works fine, but the output is messed up: $stmt -> execute(); //the query is legit, no problems there $meta = $stmt->result_metadata(); while ($field = $meta->fetch_field()) { $params[] = &$row[$field->name]; } call_user_func_array(array($stmt, 'bind_result'), $params); while ($stmt->fetch()) { $pvalues[++$i] = $row; //$pvalues is an array of arrays. row is an array //print_r($row); print_r($pvalues[$i-1]); } $stmt -> close(); I would assume that $pvalues has the results that I am looking for. My table currently has 2 rows. $pvalues has array length 2. Both rows in $pvalues are exactly the same. If i use the: print_r($row) it prints out the correct values for both rows, but if later on i check what is in $pvalues it is incorrect (1 row is assigned to both indices of $pvalues). If i use the print_r($pvalues[$i-1]) it prints exactly as I expect, the same row in the table twice. Why isnt the data getting assigned to $pvalues? I know $row holds the right information at one point, but it is getting overwritten or lost.

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • A good php framework in 2012

    - by Jormundir
    I've done a lot of googling around this, and practically all of the answers I find are pre 2011, and are answered in the usual, here are the 5 most popular frameworks... So I'd like to update this topic for 2012, I'm going to build a web application with a pretty complex back-end system driving it, and I'd like to use a framework so I don't have to reinvent the wheel. My application will be hugely user based, so I would appreciate a built in authentication/validation system. (When this is missing it takes me a good 2 weeks of intense and frivolous research to try to pick the "best" one (I don't want to roll my own, I don't think I'd do a better job than what's out there). I've looked into a tried a few, so I'll give you what I like and don't like, but I don't want to bias answers too much. I don't like: Frameworks that auto-generate bloated code. If they have the feature, fine, but if I have to use it, I get frustrated. Backwards compatibility with php4, eww. I don't need backwards compatibility at all. I like: Getting up and running quickly (but without all the auto-generation bogus), what I mean by this is that all the essentials are there, so I don't have to come to a grinding halt to research what the best 3rd party plugin is to get the feature I need. Thorough documentation, good tutorials. Good presentation of these materials. Please explain why your framework suggestion is good, don't just give the name of a framework without any justification. Thanks!
