Set Variables for a template

I haven't got so much skill, but I tried to make a Game Serverstatus Page but i didn't found something to assign any variable to the template :o

isn't this right? : WCF::getTPL()->assign('test', 'My Test Text');

Sorry ;)

Right :)
Add a @ before the dollar sign to get it as HTML -> {@$item1}

I tested but it doesn't work. ...don't know what im doing wrong.

if I understood it, then in the class i generate the wanted content and in the template i can make the output.

I tried this:

require_once(WCF_DIR.'lib/page/AbstractPage.class.php');

/**

 */
class ServerStatusPage extends AbstractPage {
    // system
    public $templateName = 'serverstatus';
    
    function __construct() {
      parent::__construct();
      //$error = 'error';
      //$item1 = 'item1';
      //$item2 = 'item2';
    
      $item1 = 'test';
      $item2 = 'test';
    
      WCF::getTPL()->assign(array(
            'item1' => $item1,
            'item2' => $item2
      ));
    }
}


and this:

class ServerStatusPage extends AbstractPage {
    // system
    public $templateName = 'serverstatus';

      //$error = 'error';
      //$item1 = 'item1';
      //$item2 = 'item2';
    
      $item1 = 'test';
      $item2 = 'test';
    
      WCF::getTPL()->assign(array(
            'item1' => $item1,
            'item2' => $item2
      ));
}


both does not work...
but in the first code i get this error: PHP notice in file C:\xampp\htdocs\wbb\wcf\templates\compiled\48_0_1_serverstatus.php (47): Undefined index: item1, in the second i get this: Parse error: syntax error, unexpected T_VARIABLE, expecting T_FUNCTION in C:\xampp\htdocs\wbb\lib\page\ServerStatusPage.class.php on line 23
so the first one seem to be better....

You don't have to use the constructor anymore, because you extend from the AbstractPage, which already has a constructor.
You class could look like this:

        $item2 = 'test';
        parent::readData();
    }
    
     /**

     */    
    public function assignVariables() {
        WCF::getTPL()->assign(array(

        parent::assignVariables();

AbstractPage or AbstractForm, depends on which class you extend from ;)

there shouldn't be any user input. so I think AbstractPage should be right.

i tried what you wrote but then i get this error:
error message: PHP notice in file C:\xampp\htdocs\wbb\lib\page\ServerStatusPage.class.php (32): Undefined variable: item1

Won't work. The problem is: Variables defined within ServerStatusPage::readData() aren't available within ServerStatusPage::assignVariables(). Either you have to use class variables or define the variables within ServerStatusPage::assignVariables() itself.
By the way: The problem with the version with your code within the constructor was: Your methoed calls the parent method before its own stuff is done. So the parent constructor method calls alle the class methods and tries to display the template. I recommed some learing of OOP, because this stuff is pretty common within WCF.

I realised that with OOP too but it's seems to be much more complicated...

It is not. If you're familiar with PHP you might know about variable scope, which means that you cannot access a variable defined outside a function unless you import it with "global" or pass it as argument. Try the example below, it works and shows you how to carry variables across different functions.

if i want to do something like this:

PHP Source code

 
1

{if isArray($infovalue)}{foreach from=infovalue item=value}{$value}<br/>{/foreach}{/if}

where do I have to place the funtion isArray? Or isn't that possible?

edit: or something like:

PHP Source code

 
1

{if $infovalue|is_array{*}don't know if that exists{*}}{foreach from=infovalue item=value}{$value}<br/>{/foreach}{/if}


now i found another solution, i rewrote a small part of the php script and it works like i want now :D

Why do you want to check if the given variable is a array?
You should know this by initialising it in your class:

PHP Source code

 
1
2
3

    public $array = array();
    public $string = '';
    public $integer = 0;


And please avoid double posts...WBB has a easy-to-use edit function.
