module extends ObjectModel or override without using override directory

[web20matrix]

I need to parse any variable passed to any static page in Prestashop and replace anything that starts with "http" (in plain text) with "a href"s. I already have the regular expression but I need to know how can I do that using a module without modifying the core functions and without using override directory for classes or controllers.

 

The variables needs to be parsed BEFORE sending the result to tpl files; I already found a solution overriding ObjectModel class but I need to do this inside a module. The problem is that it is not clear to me how I can do that because ObjectModel grabs data from database using its constructor.

 

Somehow I need to override ObjectModel constructor within my module and be able to parse the database values before sending data to any tpl included on page.

can't you just override ObjectModel, and do whatever you want in the constructor function?

[web20matrix]

yes I did override the constructor but I was wondering if I can do that within the module somehow... perhaps using hooks ?

[web20matrix]

simply put, I am trying to develop a standalone module that grabs all data from database before it is displayed and replaces text based on a regular expression. Overriding ObjectModel is not a solution because someone else might override it too

Module does not extend the ObjectModel, so the answer is no. i think anyway you cut it, you will have to override some core class
