[SOLVED] OO problems

[beredon]

Hi all.

 

First off, here's my error:

Fatal error: Call to a member function fetch() on a non-object in /dash/class/clsPage.php on line 26

 

Here's the line:

public function setContent($newContent)   { $this->content = $this->S->fetch($newContent); }

 

Here's the class that contains the offending code:

class Page {
private $S;
private $content;
public function setContent($newContent)   { $this->content = $this->S->fetch($newContent); }
public function __construct($newTemplate, $newTitle, $newHeading, $newContent) {
	$this->S = new Smarty();
	$this->S->template_dir = '/dash/templates';
	$this->S->compile_dir  = '/dash/smarty/templates_c';
	$this->S->cache_dir    = '/dash/smarty/cache';
	$this->S->config_dir   = '/dash/smarty/configs';
}
}

 

Here's how I instantiate the Page class:

$P = new Page('template.intranet.tpl', APP_NAME, APP_NAME, '');

 

And that works fine. So the Page constructor instantiates the Smarty object and stores a reference to it in $S.

 

Finally, here's the line that calls the Page->setContent function:

$P->setContent('intranet.login.tpl');

 

It appears that $S is instantiated properly from within the Page constructor (Because I can set the $S variables after I instantiate it), but then the reference is lost when it leaves the constructor. fetch() is a valid, accessible function inside the Smarty class.

 

Any help is greatly appreciated.

I fixed this error by moving the $this->S->fetch($newContent) statement from the setContent function into the class' __destruct function where it displays the template's content. It's a work-around, and I'm still unsure why the original code was working, but this method works very well and I'm happy with it.
