Randomizing a Module - PHP Not Evaluating Variables

[Punktek]

I am trying to create a module that will rotate a random banner/module title. Right now I have this (It is a plugin in the parse_templates hook) :

$array_titles = array("Hellwig Products", "GAYLORDS Lids");

$array_images = array("http://www.fordtruckclub.net/images/adspace/hellwig.png", "http://www.fordtruckclub.net/sponsors/gaylords/gl_150.png");

$array_url = array("http://www.hellwigproducts.com/", "http://www.gaylordslids.com/");

$random_number = rand(0, 1);

And have this in the module template:

<div style="padding-bottom:$vba_style[portal_vspace]px">
	<table align="center" border="0" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" class="tborder" width="100%">
		<thead>
			<tr>
				<td class="tcat" colspan="$mods[colspan]">
				<if condition="$vba_style['portal_collapsemods']">
					<a href="#top" onclick="return toggle_collapse('module_$mods[collapse]')" style="float:$stylevar[right]"><img alt="" border="0" id="collapseimg_module_$mods[collapse]" src="$stylevar[imgdir_button]/collapse_tcat$modimgcollapse.gif" /></a>
				</if>
				<span class="smallfont"><strong>$vba_style[portal_blockbullet] <if condition="$mods['link']"><a href="$mods[link]">$array_titles[$random_number]</a><else />$array_titles[$random_number]</if></strong></span></td>
			</tr>
		</thead>
		<tbody id="collapseobj_module_$mods[collapse]" style="$modcollapse">
			<if condition="$show['tablerow']">
				<tr>
					<td class="$bgclass" style="background-color: #0A1225;">
					$array_images[$random_number]
					</td>
				</tr>
			<else />
				<a href="$array_url[$random_number]"><img src="$array_images[$random_number]" border="0" /></a>
			</if>
		</tbody>
	</table>
</div>
<if condition="$show['endform']"></form></if>

For some reason though, the variables aren't being evaluated, the module just looks like this:

module.png

So I'm not sure what I am doing wrong. Any help?

Try changing the hook location to something like global_start instead. I'm not sure if vB's templates will accept variables like that, so you may need to add something like this at the bottom of your plugin too and then change the variable in your template.

PHP Code:

$myrandom_img = $array_images[$random_number];
$myrandom_url = $array_url[$random_number];

I actually figured out the problem, I simply forgot to add them to the globalized variables in the Admin CP in vBA options.

Thanks though!
