Calling the {include} function from a function-plugin?

Hi!
I want to make a built-in template editor for my page.
so every template that is displayed should get a header with a "edit" link when in edit-mode.
i have a main template that has the HTML-head and the main layout, and {include}s for the menu and the main content ...

I thought of not using the {include} function but an other (plugin) function {content} that automatically adds the header with the "edit" link.

so this function-plugin should check if edit-mode is active (assigned bool variable "edit_mode_active"?) and then either display a template that has the header and uses {include} to actually display the template or just displays it without header.

so i thought of something like this:
instead of {include} i use my own {content}:
Code:
function smarty_function_content($params, &$smarty){
   if($smarty->get_template_vars("edit_mode_active")){
      execute "{include file=$params["file"]}"; //???
   }else{
      execute "{include file='edit_header.tpl' content=$params["file"]}"; //???
   }
}

the edit_header.tpl could contain something like this:
Code:
<p><a href="edit_template.php?file={$content}">Edit</a></p>
{include file=$content}
just adding a link to the template (also could show a border or something)

this {content} function should now be used instad of {include} to automatically add headers if needed.

i used "execute" as pseudocode in the function.
is there a better way to execute smarty functions like they were in the template but from PHP in a function plugin?
Or is there at least a eval-function to execute smarty code?

thanks in advance!
greets from lower austria!

Sure.... but it is always best to return the content from a function -- so to emulate the include functionality of the template, just use the API fetch function: http://smarty.php.net/manual/en/api.fetch.php and return the result (also, you can assign any template variables that are required before you do the fetch).

Another idea is to implement a custom resource that does the checks for you -- that way you can still use normal {include} calls. Its all in the manual -- but feel free to ask if you need more help Wink
