It saves the eval(template). eval() is kind of "bad", because it can't be cached by a PHP cache.

I'm coming back to post that this hack has sped up my site sooo much faster! Thanks ORban

Not having to edit templates and making installs easier for the end user. ;)

Uhm, you can add templates to product.xmls?

Also you might have modified the templates so the str_replace doesn't even work anymore.

You can do it with search and replace. Check out my Last 15 Searches hack. I did it in there. More products are being released that do this now. I do it whenever I can for the reasons stated above. ;)

Somebody might not have a $navbar.

So far, that hasn't happened yet and really shouldn't unless they are REALLY screwing with their templates. That is standard in alot of templates for vb. When I do search and replaces, I only work from the Master Template set (the default one) and no other products or hacks that I know of use that spot in that certain template. ;)

Why not add $last15searches to the navbar template?

Like $vbulletin->templatecache['navbar'] = $vbulletin->templatecache['navbar'].'.$last15searches'; or something, because would work with the template cache too.

Because the replace for that is a template edit. You would then have to manually edit the template. With the way I did it, you don't have to touch the template and it will be better on ungrades where vb adds to or changes to the template. ;)

No you don't? That's PHP code to be run in the plugin, instead of your str_replace.
