Set Variables for a template

Sorry · Feb 8th 2012

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

PHP

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

if you want to pass more than one

Sorry · Feb 8th 2012

ok thanks for your fast reply, and then i get them how? (in the template) with {$item1} and {$item2} ?

Christopher Walz · Feb 8th 2012

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

Sorry · Feb 8th 2012

ah okay thanks unfortunately i have to go off for today, will try it tomorrow

Sorry · Feb 10th 2012

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:

PHP

<?php
// wcf imports
require_once(WCF_DIR.'lib/page/AbstractPage.class.php');




/**
 * Minecraft ServerStatus
 *
 * @author      Sorry
 * @copyright   fightcraft.de
 * @package     no
 * @license     ask admin@fightcraft.de
 */
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:

PHP

<?php
// wcf imports
require_once(WCF_DIR.'lib/page/AbstractPage.class.php');




/**
 * Minecraft ServerStatus
 *
 * @author      Sorry
 * @copyright   fightcraft.de
 * @package     no
 * @license     ask admin@fightcraft.de
 */
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:

PHP

<?php
// wcf imports
require_once(WCF_DIR.'lib/page/AbstractPage.class.php');




/**
 * Minecraft ServerStatus
 *
 * @author      Sorry
 * @copyright   fightcraft.de
 * @package     no
 * @license     ask admin@fightcraft.de
 */
class ServerStatusPage extends AbstractPage {
    // system
    public $templateName = 'serverstatus';




	
	/**
	 * @see Page::readData()
	 */
    public function readData() {
		$item1 = 'test';
		$item2 = 'test';
		parent::readData();
	}

 	/**
	 * @see Page::assignVariables()
	 */    
    public function assignVariables() {
		WCF::getTPL()->assign(array(
			'item1' => $item1,
			'item2' => $item2
		));
		parent::assignVariables();
	}
}




?>

okay thank you... and where can i look up which functions names (example: public function readData()) i have to use?

Christopher Walz · Feb 10th 2012

AbstractPage or AbstractForm, depends on which class you extend from

Sorry · Feb 10th 2012

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

Christopher Walz · Feb 10th 2012

PHP

public function readData() {
  parent::readData();
        $item1 = 'test';
        $item2 = 'test';

    }

try it likes this.

Sorry · Feb 10th 2012

again 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.

Sorry · Feb 10th 2012

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.

PHP

<?php
// wcf imports
require_once(WCF_DIR.'lib/page/AbstractPage.class.php');




/**
 * Minecraft ServerStatus
 *
 * @author      Sorry
 * @copyright   fightcraft.de
 * @package     no
 * @license     ask admin@fightcraft.de
 */
class ServerStatusPage extends AbstractPage {
	// system
	public $templateName = 'serverstatus';

	public $item1 = '';
	public $item2 = '';

	/**
	 * @see Page::readData()
	 */
	public function readData() {
		parent::readData();

		$this->item1 = 'test1';
		$this->item2 = 'test2';

	}

 	/**
	 * @see Page::assignVariables()
	 */    
	public function assignVariables() {
		parent::assignVariables();

		WCF::getTPL()->assign(array(
			'item1' => $this->item1,
			'item2' => $this->item2
		));
	}
}
?>

i knew that but i was a little bit confused...

thank you for your example. it works, i think a can work with it

Sorry · Feb 10th 2012

it works very well now now i've only to improve the design.

and i've to try foreach in the template within an array ... i'll hope it works

Sorry · Feb 10th 2012

if i want to do something like this:

PHP

{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

{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

Christopher Walz · Feb 11th 2012

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

PHP

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

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