PHP - Creating Object/class Properties Dynamically At Run Time
Hi there,
I am just wondering which way is the correct one if you want to create object properties/attribute dynamically at run time using magic method __set(), __get(), for example: class Foo{ public $data = array(); public function __set($name,$value){ $this->data[$name] = $value; } public function __get($name){ if ( isset($this->data[$name]) ){ return $this->data[$name]; } } } Or using the below way class Foo{ public function assign(array $data){ foreach($data as $key => $value){ $this->$key = $value; } } } I just encountered the second way in many places and I am totally confused . Is the __set() method called implicitly by the PHP engine in the second way or what? how come this is considered as a valid code ? your usual help is appreciated Similar TutorialsHi Can you call Class A's methods or properties from Class B's methods? Thanks. I'm doing some basic object coding to get my head around OOP PHP, but I've come across something I can't get to work. I've got two identical peices of code, MyClass is defined, MyClass2 is then defined as an extension of MyClass. MyClass has three properties Public, Private and Protected. In my first example I can access Public and Protected via a method in MyClass2, this class does NOT have a constructor. The second example has a constructor but I cannot access Public: Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <body> <?php ECHO "MyClass2 does not have a constructor, Public & Protected both echo correctly from MyClass2->printHello!!!<BR>"; /** * Define MyClass */ class MyClass { public $public; protected $protected; private $private; protected $varXXX; function __construct() { $this->public = "Public"; $this->protected = "Protected"; $this->private = "Private"; //$this->printHello(); } function printHello() { echo $this->public . "!!!<BR>"; echo $this->protected . "!!!<BR>"; echo $this->private . "!!!<BR>"; } } /** * Define MyClass2 */ class MyClass2 extends MyClass { // We can redeclare the public and protected method, but not private protected $protected = 'Protected2'; /* function __construct() { echo $this->public . "#<BR>"; echo $this->protected . "#<BR><BR>"; //echo $this->private . "???<BR>"; } */ function printHello() { echo $this->public . "???<BR>"; echo $this->protected . "???<BR><BR>"; //echo $this->private . "???<BR>"; } } $obj = new MyClass(); //echo $obj->public . "<BR>"; // Works //echo $obj->protected; // Fatal Error //echo $obj->private; // Fatal Error //$obj->printHello(); // Shows Public, Protected and Private $obj2 = new MyClass2(); //echo $obj2->public; // Works //echo $obj2->private; // Undefined //echo $obj2->protected; // Fatal Error $obj2->printHello(); // Shows Public, Protected2, Undefined ?> </body> </html> RESULTS IN: Public??? Protected??? Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <body> <?php ECHO "MyClass2 DOES have a constructor, Public does not work from MyClass2->printHello!!!<BR>"; /** * Define MyClass */ class MyClass { public $public; protected $protected; private $private; protected $varXXX; function __construct() { $this->public = "Public"; $this->protected = "Protected"; $this->private = "Private"; //$this->printHello(); } function printHello() { echo $this->public . "!!!<BR>"; echo $this->protected . "!!!<BR>"; echo $this->private . "!!!<BR>"; } } /** * Define MyClass2 */ class MyClass2 extends MyClass { // We can redeclare the public and protected method, but not private protected $protected = 'Protected2'; function __construct() { echo $this->public . "#<BR>"; echo $this->protected . "#<BR><BR>"; //echo $this->private . "???<BR>"; } function printHello() { echo $this->public . "???<BR>"; echo $this->protected . "???<BR><BR>"; //echo $this->private . "???<BR>"; } } $obj = new MyClass(); //echo $obj->public . "<BR>"; // Works //echo $obj->protected; // Fatal Error //echo $obj->private; // Fatal Error //$obj->printHello(); // Shows Public, Protected and Private $obj2 = new MyClass2(); //echo $obj2->public; // Works //echo $obj2->private; // Undefined //echo $obj2->protected; // Fatal Error $obj2->printHello(); // Shows Public, Protected2, Undefined ?> </body> </html> RESULTS IN: # << Missing the property's contents Protected2# ??? << Missing the property's contents Protected2??? Any ideas why I cannot access the property's contents in the second example when the only difference is that it has a constructor? I need to set a deep property if it is undefined or NULL such as shown below:
function setProperty($value, stdClass $config, $p1, $p2, $p3, $p4) {
if(!isset($config->$p1->$p2->$p3->$p4) || is_null($config->$p1->$p2->$p3->$p4)) {
$config->$p1->$p2->$p3->$p4=$value;
}
}
$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));
setProperty(321, $config, 'a','b','c','x');
setProperty(321, $config, 'a','b','c','y');
But I wish the function to work regardless of property depth and came up with the following. Recommendations for a cleaner way? Maybe I should be working with arrays and array_merge_recursive()?
function setProperty($value, stdClass $config, array $properties) {
$property=array_shift($properties);
if(!count($properties)){
if(!isset($config->$property) || is_null($config->$property)) {
$config->$property=$value;
}
}
else {
if(empty($config->$property) || !is_object($config->$property)) {
$config->$property=new \stdClass();
}
setProperty($value, $config->$property, $properties);
}
}
$config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123]));
setProperty(321, $config, ['a','b','c','x']);
setProperty(321, $config, ['a','b','c','y']);
I have mysqli object in Database class base: [color=]database class:[/color] class Database { private $dbLink = null; public function __construct() { if (is_null($this->dbLink)) { // load db information to connect $init_array = parse_ini_file("../init.ini.inc", true); $this->dbLink = new mysqli($init_array['database']['host'], $init_array['database']['usr'], $init_array['database']['pwd'], $init_array['database']['db']); if (mysqli_connect_errno()) { $this->dbLink = null; } } } public function __destruct() { $this->dbLink->close(); } } Class derived is Articles where I use object dBLink in base (or parent) class and I can't access to mysqli methods (dbLink member of base class): Articles class: require_once ('./includes/db.inc'); class Articles extends Database{ private $id, .... .... $visible = null; public function __construct() { // Set date as 2009-07-08 07:35:00 $this->lastUpdDate = date('Y-m-d H:i:s'); $this->creationDate = date('Y-m-d H:i:s'); } // Setter .... .... // Getter .... .... public function getArticlesByPosition($numArticles) { if ($result = $this->dbLink->query('SELECT * FROM articles ORDER BY position LIMIT '.$numArticles)) { $i = 0; while ($ret = $result->fetch_array(MYSQLI_ASSOC)) { $arts[$i] = $ret; } $result->close(); return $arts; } } } In my front page php I use article class: include_once('./includes/articles.inc'); $articlesObj = new articles(); $articles = $articlesObj->getArticlesByPosition(1); var_dump($articles); [color=]Error that go out is follow[/color] Notice: Undefined property: Articles::$dbLink in articles.inc on line 89 Fatal error: Call to a member function query() on a non-object in articles.inc on line 89 If I remove constructor on derived class Articles result don't change Please help me I'm looking for any guidance on how to dynamically create css files. I want users to be able to select colors for fonts/backgrounds, borders, etc. from a form which they will submit and it will create a css file and put it in a certain folder. Can someone point me in the right direction? This code works: // create object $zip = new ZipArchive(); // open archive if ($zip->open('./download/zipfile.zip', ZIPARCHIVE::CREATE) !== TRUE) { die ("Could not open archive"); } but, I want to create the name of the zip file dynamically. The following code does not work ... doesn't give me an error, just doesn't create the zip file: // create object $zip = new ZipArchive(); $thisTime = time(); // open archive $thisZip = './download/'.$thisTime.'_download.zip'; $thisZip_b = $thisTime.'_download.zip'; if ($zip->open($thisZip, ZIPARCHIVE::CREATE) !== TRUE) { die ("Could not open archive"); } thanks in advance oh wise ones. mrsburnside What I want to do is create a table out of records from a table that shows an image and a radio button under the image (so I would imagine it would be in 2 rows). I want it to have 3 columns across. Here's what I have to get and output the results: $fabricsql = "SELECT * FROM Fabric f, Images i WHERE f.SKU = i.SKU"; //echo $fabricsql; $fabricResult = mysql_query($fabricsql); $i=0; while($fabricAssoc = mysql_fetch_assoc($fabricResult)){ //echo $fabricAssoc['SKU']. "+ ".$fabricAssoc['Name']; echo "<a href=\"\"><img src='../../".$fabricAssoc['ThumbPath']."' alt='".$fabricAssoc['Description']."' width='".$fabricAssoc['ThumbWidth']."' /></a><br /> <input type=\"radio\" name=\"fabricSelect\" value='".$fabricAssoc['SKU']."' id=\"RadioGroup1_".$i."\" /><br /><br />"; $i++; } Any help is much appreciated. I'm not even sure this is the best way to go about this so any suggestions are appreciated. I am creating a dynamic form in php. And i want to add fckeditor to this dynamic form. so any idea about to add fckeditor to a dynamically creating form in php??? Any Help please??? I have not created any code for this as I dont know where to start, or what its even called. I am on about trying to create a page dynamically depending on the id which is selected. Parts of the URL will change depending on what id is selected for example: 'http://www.facebook.com/home.php?sk=h. i am wanting to create a video website, where when the thumbnail of a video is clicked, a new page is loaded with that more details of the video and the video itself, and im guessing the url would change to identify the id of the video. I cannot create a page for every video by hand, as i will have many videos and this is not very efficient. I am just after the name of this technique or a pointer to a tutorial for how to achieve this. Thanks, Matlab I am trying to use Google's map API to dynamically create new maps. For example, I would like to be able to make a replica of this page using PHP. I just don't see where in the API it allows you to add all this information, such as adding categories, details, pictures, videos, etc. I've been researching for quite a while, and can't seem to come up with something that is similar to what I'm trying to do. Here is a link I found that shows you how to create maps, but I still don't see how to add all the information that you could if you did it manually! http://code.google.com/apis/maps/documentation/mapsdata/developers_guide_protocol.html#CreatingMaps It would be great if someone can point me in the right direction. Thanks! I was thinking of adding queries using a basic HTML form. To be able to do that I was thinking of having a Query sql table which has all the main create, insert, remove, update, delete and select general syntax into it. The idea is to be able to choose a query based on a HTML select option and add the values to a field, any idea how can you do that dynamically?
Hi all, Hope to find you all good. I have the following, which creates a php file. This works fine and without error. However, once created, the content of the page, which is got from the Database, is not showing.

Please note that this is just a project and will not be going live. It's for learning purposes and I am aware there are some vulnerabilities within parts of the code. Any assistance with the above issues though would really be appreciated. Thanks and have a ripper evening. Hi, I have two timepickers start time and end time.When I select start time,the end time should have all the times disabled before start time.I am having Add button.When add button is clicked,again two timepickers are added.In these two,I can't able to set mintime of end timepicker from start time.Here is the code <div id='adddiv'> <input type="hidden" name="count" id="count"> <p>From:<input type="text" style="width: 70px;" id="timepicker1" name="visiting_time_start"/> To:<input type="text" style="width: 70px;" id="timepicker2" name="visiting_time_end"/> <a href='#' id='sadd'><img src="<?php echo base_url();?>template/images/plus_button.png" alt="Add"></a> </p></div>
$(document).ready(function() {

For timepicker1 and 2 its working fine.For dynamically created timepickers,I am not able to set mindate and max date.Can anyone help me...Hi, I have decided to try and write some OO php. I have a simple class with one function. I am trying to instantiate an object of that class using the new operator but get an error. Parse error: syntax error, unexpected T_OBJECT_OPERATOR in C:\wamp\www\School\addcourse.php on line 38 Code: [Select] <?php $CDBController = new CMasterDataController; //THIS IS LINE 38 CMasterDataController->PerformQuery("SOME SQL HERE"); ?> I am including the file that contains this class (CMasterDataController) in this file (addcourse.php). The version of PHP i am using is 5.3.8. Does anybody know what I am missing? Thanks, Joe Hello everyone, I have a PHP Laravel CRUD application I made where I am using MVC style. I have controllers views and models. My database migration is made and my table in the database is made with php artisan migrate. I am using php 7.3 and laravel 5.8. On my create view I go to create a single object in my database and my errors are thrown saying nothing in text box (no input) If I comment out the errors then just I click my submit button and nothing happens nothing is entered into my db. I have looked at many different crud examples and I am not sure why my object isn’t being created. Here is what I have
//view create
@section('main')
<section id="section-content" class="text-center">
<div class="container contentdiv rounded">
<div class="row">
<div class="col-md-12">

My env is setup correctly I just don’t get the not creating object. I would to create my own php class for my website but i dunno the fundamentals of PHP CLASSES. Can anyone teach me how to create and use php class. best if you go into deeper explanations. My main subject is to create a social net site Write a class for feeding a horse. The Horse object should keep track of the last time it was fed and calculate when it is hungry. Assume there is another class that checks the horse every 10 minutes to see if it is hungry and if it is, it calls another method which feeds it. There should be about 3 methods on the class, but more can be added if needed. I am calling an object from another class in the constructor of first class but when I call it in another function it does not access it's object. Here is the code. Code: [Select] <?php /* This is controller.php used to control the flow of data between view.php and model.php. This file cotains all the controlling mechanism of the data It was created on 11th Feb 2011 By Narjis Fatima for an Open Source Project and contains all the includes to the database etc. */ include ("view.php"); include ("functions.php"); $name = stripslashes($_GET['username']); $email = stripslashes($_GET['email']); //echo "in controller.php"; check_validate_input($name, $email); $newUser = new controller($name, $email); $action=$_GET['t']; $newUser->display_view($action); class controller { public $my_model; //is an object of model class public $user_info;//=array('id' , 'username' ,'role','email','interests','location', 'homepage'); function __construct($name,$email) { $my_model = new model(); $user_info = $my_model->check_members($name,$email); echo "<pre>"; print_r ($user_info); } function __destruct() { } function display_view($token) { echo "In display function"; echo "<pre>"; print_r ($user_info); if ($this->user_info == NULL) { if (($token=="register")) { show_registration_form(); } else{ show_mailing_form(); } } if ($this->user_info['role'] == "admin") { $myView = new view(); $myView->view_admin_menu(); } if ($this->user_info['role'] == "user") { $myView = new view(); $myView->view_user_menu() ; } }//close of function display_view() } /* name and email cominfg from index.php would be checked by the controoler class to be checked if it a vaild name and email. The database would be connected n the model.php*/ ?> The code for model.php is as follows Code: [Select] <?php //This is model.php created on 10th Feb 2011 .It deals with daytabase connection // //By NArjis Fatima //For the project of EDUForge an Open Source Software //include ("register.php"); class model{ public $dbh; public $user_arr=array('username','password','email','location','interest','homepage'); //cunstructor of model class //function to connect to database function __construct(){ try{ $this->dbh = new PDO("mysql:host=localhost;dbname=phpfaqproject",'root',''); //echo "connected"; } catch(PDOException $e){ echo $e-> getMessage(); } } public function check_members($username,$email) { //get_connected(); $sql = "SELECT * FROM account WHERE (username='" .$username ."' AND email='" .$email."')"; $sth = $this->dbh->prepare($sql); $sth->execute(); $result = $sth->fetch(); /* echo('<pre>'); print_r($result);*/ return ($result); } public function insert_data($user_info) { //$user_info = $user_in; //$dbh; try{ $dbh = new PDO("mysql:host=localhost;dbname=phpfaqproject",'root',''); //echo "connected"; } catch(PDOException $e){ echo $e-> getMessage(); } $dbh->exec("INSERT INTO account (username, userpassword, email, role, location, interest, homepage) VALUES ('" .$user_info['username']."','".$user_info['password'] ."','".$user_info['email']."', 'user','".$user_info['location']."','".$user_info['interests'] ."','".$user_info['homepage']."')"); } } ?> Please somebody help me. I am really stuck. I am also sending my attachment. I have a class which is injected with various objects and those objects contain other objects where some of them contain content from various APIs, user data, etc. I would like to obtain a persistent copy of one of these sub-objects so I may modify my class and test it without having to recreate it each time. Anyway existing tools to automate this process? One thought is using reflection to access all the properties and recursively go over each which somehow creates some JSON file which can act as the input to some factory class to create the same instance? Or maybe some custom function which somehow creates some executable which reflects the bits and bytes in the PHP object? Thanks why is this not working? <?php class registration{ public $email = $_POST["email"]; public $username = $_POST["username"]; public $password = $_POST["password"]; //var $username = $_POST["confirmPassword"]; function validateFields(){ echo $this->$email; echo $this->$username; echo $this->$password; //echo $this->$confirmPassword; } } registration->validateFields(); ?> Im getting error: Parse error: syntax error, unexpected T_VARIABLE on the first property declaration $email. |
