Module that embeds JS in page doesn't work

[alexandru.topliceanu]

Hi guys,

 

I'm developing a prestashop module that embed a snippet of javascript in the footer of the site.

The problem: it doesn't show up!

I'm clearing smarty cache on install by using the following code in the hook

 

public function hookFooter ($params) {
 global $smarty;
 //force refresh of the cache
 $smarty->compile_check = true ;

 

 

I'm also instructing my clients to temporarily clear smarty cache in the Preference > Performace tab.

What am i missing? How can i clear the cache in a programmatic way and then enable it back?

 

Thanks for your help

Alex
