Plugin Problem

Here is the template code:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>

<div id="slider">

</div>

<vb:literal>
<script type="text/javascript">
$(window).load(function() {
var total = $('#slider img').length;
var rand = Math.floor(Math.random()*total);
	$('#slider').nivoSlider({
		effect:'random',
		slices:15,
		animSpeed:500,
		pauseTime:7000,
                startSlide:rand,
		directionNav:false,
		directionNavHide:true,
		controlNav:false,
		controlNavThumbs:false,
                controlNavThumbsFromRel:false,

		captionOpacity:0.8,
		beforeChange: function(){},
		afterChange: function(){},
		slideshowEnd: function(){}
	});
});
</script>

I also did an experiment where the plugin called a non-existent template. Not sure if an Internal Server Error would normally cause this, but it did.

I tested to make sure - using a non-existent template should just result in a (more or less) empty string.

If you haven't already, maybe try this code:

PHP Code:

$templatevalues['banner_rotator'] = "Test Banner Rotator";
vB_Template::preRegister('header', $templatevalues); 


I'm not really an expert on these kinds of thing, but based on what I've seen before I'm kind of getting a feeling like it's a problem other than what you're doing, like maybe a php configuration issue or something wrong with the vb installation. Is this a new install of vb? Did you try running "Suspect File Versions" under Maintenance in the adminCP?

This is an upgrade to vB 4.1.4 from 3.8.4.

I changed the plugin code and that stopped the Internal Server Error. Not sure why

$templater->render()

was crashing the system, but it seems to have been the cause.

But the images in the slider won't load. Not sure what's up with that, but that's a different problem entirely.

[kh99]

Well, in retrospect I guess that didn't help much since you already knew it was the call to render causing the problem. But taking it out isn't really a fix since you should be able to reder a template there if you want.

Could that rendering command being deleted cause the images not to load? Those are called in the template itself.

Also, should it be

$template->render()

as opposed to

$templater->render()

with emphasis on the r in templater?

[Lynne]

$templater->render() is correct since that is what he defined.

Try this for preregistering:

vB_Template::preRegister('header', array('templatevalues' => $templatevalues));

And did you already define $templatevalues as an array somewhere?

[Lynne]

Also, is it *any* template you render via a plugin on that site that causes issues, or just this one? If it is any template, then I would suspect something like mod_security or suhosin to be the problem. Have you run diagnostics > problematic webserver modules?

I added that line but it didn't fix the problem. And I haven't definre $templatevalues as an array anywhere.

Nope... just this plugin. And our host said that mod_security was blocking it but they whitelist it for us.

Problematic Webserver pops up with No to "Module Loaded" and "AJAX Unicode Issue".

Just a minor update. When I add your code:

vB_Template::preRegister('header', array('templatevalues' => $templatevalues));

This is the error I get:

Fatal error: Call to a member function render() on a non-object in /home/fpaul46/public_html/forum/includes/class_core.php(4257) : eval()'d code on line 2

[thunderclap82]

No other ideas?

[kh99]

Ah, yeah, I can't believe I didn't think of this before, but did you try a different hook location, like maybe parse_templates? The one you're using is actually in the vB_Template code and is called when a variable is registered, so that could be causing strange things to happen.
