[TUTORIAL] How to (finally) override Prestashop Modules’ core files

[NemoPS]

Although it's about core development, this topic will certainly interest template developers as well.

YES!

 

We can finally override modules from other modules, since the nre 1.6.0.11. Yes, no mention in the changelog

 

Here is my tut!

Thanks great and quick tutorial :-)

 

Think it is good option to theme developers to pack overrides in one module.

 

Also to watch out for possible conflicts when doing overrides.

Thanks for this very useful info and for explanation how it works.

Good tutorial Nemo, however there is no need to delete class_index.php

[oldlastman]

No, you can only override base file of the module

[NemoPS]

Oh, there is a bug concerning class_index.php in .09, but it should be there in .11, is it not? My version has it

[Krystian Podemski]

What bug? Overrides for modules works properly from 1.6.0.13

And class_index is not there? I admit I didn't try out that  version yet. 1.6.0.9 has a bug in PrestashopAutoload.php, the class_index file never gets generated

[Krystian Podemski]

Modules are not autoloaded so there is no need to autoload overrides, and I didn't notice any problems with class_index.php regeneration

Can't get this to work with blocklayered

I want to tweak the title output this way https://www.prestashop.com/forums/topic/392632-page-title-coming-in-the-category-heading-after-selecting-a-layed-in-layered-navigation-module/?do=findComment&comment=1917643

 

I'm trying to override ajaxcall() within 'blocklayered.php':

if (!defined('_CAN_LOAD_FILES_'))
    exit;

class BlockLayeredOverride extends BlockLayered
{
    
    public function ajaxCall(){ ...

[NemoPS]

I'm not sure that will work, since the file is included manually in blocklayered-ajax.php

[javierllinas]

That's what I thought. I don't know if blocklayered-ajax.php can be overriden somehow...

[NemoPS]

Nope, it's actually an "external" file so it can't. You might want to hardcode the modification and keep a backup of it in case your upgrade

[javierllinas]

That's true.

 

What I'm going to do is duplicate the module, as I modified some tpl, to build a 'new' one.

 

What we learn here is that we cannot override all kind of modules, I guess.

 

As always, thanks for the feedback Nemo1

 

All the best.

[NemoPS]

Yeah, correct.

Also, Some of them have private methods which cannot obviously be overridden. Which also makes overrides useless in the first place

Quote from website:

 

Since this silence towards the community is getting pretty annoying, I hope the Prestashop team will soon try to have more consideration for the user and developers base, informing us when such a new feature is released. Just a small code snippet for them:

2

if($prestashop - $community)

    die();

 

I think they heard you

 

Probably many developers still don't know about it as the introduction was a little "silent":
