Smarty

[himerus]

I'm just looking for something that will be either called from smarty or from my PHP file in a footer section that will determine if a specific template file/files have been included earlier in the page, and if it has, it should add an aditional template to the footer, or simply, assign a variable specifying such..

Example... template A is a custom template that may or may not include another template inside of it...

Template A:
text
text
text
<!--{include file="templateb.tpl"}-->
text
text
text


I need to determine if the templateb.tpl has been included at the end of my script. If it was done inside smarty, it would simply add another line of html, or if from PHP, it would assign a variable that would be handled in the footer...

I didn't see anything right off from searching, or in the documentation...

I'm sure it's an easy solution, TIA for advice.

for some clarification, what I need is to know if a certain template or template has been called ANYWHERE throughout the page that has been compiled...

it would be called last, and display custom content dependant on if the template in question has been called.

Could you do something like:

$smarty->assign('include_b', true);

Then in the templates:

{if $include_b}{include file="template_b.tpl"}{/if}

{if $include_b}do footer logic here{/if}

In other words, don't rely on testing if a template got included, instead have your template behaviors act upon an explicitly assigned value, which includes template inclusion and footer text.

The problem I see is that Smarty doesn't really know. Smarty doesn't make any attempt to keep or record the internal structure of a template.

There may be better ideas out there but one thing you can consider is using a prefilter. Prefilters allow you to modify the template sourcecode before it is processed by Smarty. In practice, you would have your prefilter scan the template sourcecode for {include} tags that match your criteria. You could then do something to match your needs, either insert an additional {include} tag for your tracking template in-place or set some global variable with a status indicator of some sort -- or what-have-you. You'll have to roll up your sleeves some but it might do the trick.

On-the-other-hand, you would likely be way better-off writing a custom plugin function for those special types of includes. You could still accept the 'file' parameter and your function could fetch the template and return it along with doing whatever other processing and/or appending any other data that it involves.

Yet another idea is to provide a custom resource that would potentially concatenate two templates if the requested path matched your criteria. You could then set this as the default resource type if you wanted that behaviour always.

One last thing I can think of is to override smarty::_include() -- but that's crazy talk.

Okay, my solution is this... I've added a function into the smarty core that caches the template names that have been called in an array, where I can call that with my php script later, and take action if needed, not just on this situation, but with others I may need to be aware of templates being dynamically called throughout the called page.

I have everything working except I'm not sure which part of the smarty core is including files that have been included in a template, and not called from PHP. It is working properly for any template called using fetch() or display(), but where in the core files are that scan and include these sections? {include file=""}
