I have a function that creates a template, assigns variables and returns the output.
I would like to change those variables in another php file, how can I do that ?


display_product.php :
Code:
<?php
function get_product_details_html(){
 $tpl = $GLOBALS['tplEngine']->createTemplate('product_details_html.tpl');
 $tpl->assign('product_detail_html_zone', 'some html code');
.....
}
}


product_details.php :
Code:
<?php
$output = get_product_details_html();
$output .= hook_get_product_details_html();
echo $output;


myPersonalModule.php :
Code:
<?php
  function hook_get_product_details_html() {

[i]... here I would like to access to the current template and change some variables....[/i]
  }
}

I think the variables are always retrievable once assigned.
Code:
$currentTemplateVar = $tpl->getTemplateVars("product_detail_html_zone");

Your template call should be the last thing you do in your code.
There should be no "retrieve something from template" necessary.
