Posted: Sun Mar 01, 2009 1:25 am Post subject: {foreach} Use methods of objects stored in array |
|
|
Hello
I'd problems with accessing my getter-functions of my objects stored in an array. I didnt want to assign each object so I found this solution to access class-methods in a {foreach} even if the objects are stored in an array.
Please take a look at the following Wrapper and give me feedback!
Code: |
<?php
/**
* @author Michael Schnyder
* @version 2009-02-28
*
* Use this Class to have full access Object Arrays in Smarty Template Engine
*
* Smarty can handle Arrays of Object, but only if the Array ist returned from a Function, while running a smarty-tpl.
* If you assign an array of Objects to smarty, you won't be able to access them in an forach-loop. But if you have
* the ability to call a function of a Object wich returns an array of other objects, it is possible to use them.
*
* Example
* =======
*
* Assign variables to smarty NOT WORKING!!!
* -----------------------------------------
*
* PHP:
* class MyClass {
* private $foo;
* public function __construct($v) { $this->foo = $v; }
* public function getFoo() { return $this->foo; }
* }
*
* $smarty->assign('ObjectArray', array(new MyClass("bar"), new MyClass("bar2"));
*
* Smarty:
* {foreach from=$ObjectArray item=oi}
* {$i->getFoo()}
* {/foreach}
*
*
* Assign Wrapper to smarty, WORKING!!!
* ------------------------------------
*
* PHP:
* class MyClass {
* private $foo;
* public function __construct($v) { $this->foo = $v; }
* public function getFoo() { return $this->foo; }
* }
*
* class Wrapper {
* function giveMeArray() {
* return array(new MyClass("bar"), new MyClass("bar2"));
* }
* }
*
* $smarty->assign('ObjectArrayWrapper', new Wrapper());
*
* Smarty
* {foreach from=$ObjectArrayWrapper->giveMyArray() item=oi}
* {$i->getFoo()}
* {/foreach}
*/
class SmartyObjectArrayWrapper {
private $OAs;
function __construct() {
$this->OAs = array();
}
function addObjectArray($oa, $accessFunction) {
$this->OAs[$accessFunction] = $oa;
}
//Handle all other Functions
function __call($name, $arruments) {
if(array_key_exists($name, $this->OAs)) {
$res = $this->OAs[$name];
}
return $res;
}
}
?>
|
The trick is to call inside the tpl a function (of the Wrapper-Object) wich returns the array of objects in runtime of smarty an not while assign.
If have no Idea why it doesn't work with simplier way, can anyone tell me?

It looks you are working with singleton design pattern. Please try the following, if this works for you:
* Make the variable static too, to hold the objects, instead of just private.
* Assign the object by reference.
Another, {$i->getFoo()} looks irrelevant in this piece of code. |
