Replace Navbar Link with Image

[Dax IX]

I'm doing something totally wrong here, and if someone could give me a little help I'd really really appreciate it.

I'm trying to replace some navbar links with images, and it's not working. I'm using an edited template and a plugin.

vbcms_navbar_link:

<vb:if condition="$vboptions['selectednavtab'] == 'vbcms'">
<li class="selected">
    <a class="navtab" href="{vb:raw vboptions.site_tab_url}{vb:raw session.sessionurl_q}">{vb:rawphrase site}</a>
    <ul class="floatcontainer">
        {vb:raw template_hook.vbcms_navbar_start}
        <vb:if condition="$links">
            <vb:each from="links" value="link">
                <li><a href="{vb:raw link.url}"><vb:if condition="$pngexists"><img src="$pngexists" border="0" /><vb:else />{vb:raw link.title}</vb:if></a></li>
            </vb:each>
        <vb:else />
            <li class="hidden">&nbsp;</li>
        </vb:if>
        {vb:raw template_hook.vbcms_navbar_end}
    </ul>
</li>
<vb:else />
    <li><a class="navtab" href="{vb:raw vboptions.site_tab_url}{vb:raw session.sessionurl_q}">{vb:rawphrase site}</a></li>
</vb:if>

Plugin:

PHP Code:

$pngtitle = '{vb:raw link.title}';

$pngtitle = str_replace(' ', '', '$pngtitle');

$pngexist = '/home/starship/public_html/fora/images/buttons/' . $pngtitle . '.png';

if (file_exists($pngexists)) {

$pngexists = '/fora/images/buttons/' . $pngtitle . '.png';

} 


First of all, I'm not sure what hook to use for this plugin.

Other than that, should this work?

Thanks!

I just realized that I have this in the wrong forum.

Could a moderator please move it to vB4 programming?

Thanks!

using the same template, I've read a little more about template variables, but I'm still trying to figure this out.

Forgive my ignorance in programming.

PHP Code:

$pngtitle = '{vb:raw link.title}';

$pngtitle = str_replace(' ', '', '$pngtitle');

$pngexist = '/home/starship/public_html/fora/images/buttons/' . $pngtitle . '.png';

if (file_exists($pngexists)) {

$pngexists = '/fora/images/buttons/' . $pngtitle . '.png';

}else{

$pngexists = '';

}

/* render template and register variables */
$templater = vB_Template::create('navbar');
    $templater->register('pngexists', $pngexists);
$templater->render();

Again, please forgive my ignorance here, but how do you translate the template variable {vb:raw link.title} to php for my plugin?
