how to execute some code after a post(product) is created/updated in prestashop

[sinai]

Hi all,

 I want to know how can I execute some codes after a product is created/updated in prestashop.

I have done such things for wordpress via the functions.php file inside a theme. I want to know whether there is a similar way in prestashop or not?

I want to purge the cache server after a product is updated/created.

Thanks in advanced.

You can use action hooks, actionProductAdd and actionProductUpdate
You need this hooks on the module install and add function for each hook
Hook::exec are called on AdminProductController.php

Hook::exec('actionProductAdd', array('id_product' => (int)$this->object->id, 'product' => $this->object));
public function HookActionProductUpdate($params){
Var_dump($params['product']);exit;
}

Cordially.

Thank you tarek.fellah.

I found the AdminProductsController.php which is located in the path /home/username/public_html/controllers/admin.

I want to know whether this file is updated or not if someone updates its prestashop or change its theme? Because if it is updated whenever presta release a new version or by changing a theme, all my codes will disappear!

Thank you.

You can do like this on your module 

public function HookActionProductUpdate($params){
Var_dump($params['product']);exit;
}

This is what i do and it's working.
I don't think Prestashop will change hook names.

I am a little confused! because I am not an expert PHP developer. I just want to execute some simple php codes. May you please tell me where should I add the function and the hook?

I added a function at the end of the AdminProductsController.php file, and call it just after the line

Hook::exec('actionProductAdd', array('id_product' => (int)$this->object->id, 'product' => $this->object));

in function processAdd()

the function is as follows:

public function update_test()
    {
      file_put_contents("/home/username/public_html/controllers/admin/test.txt","OK");
      return ;
    }

but I get the following error:

Got error 'PHP message: PHP Fatal error:  Call to undefined function update_test() in /home/smilehyper/public_html/controllers/admin/AdminProductsController.php on line 1889

You should learn to create a module, i think you need only a simple module http://doc.prestashop.com/display/PS16/Creating+a+first+module

[sinai]

You are right. I studied a little about creating a simple module and then created a module and registered my desired action hooks. 

I am developing it now.

Thank you.

Does this hookactionProductAdd work in PS 1.7x?

I've tried to use it but it doesn't seem to fire when adding a product in backoffice.

@veijari Hook actionProductAdd does exist in PrestaShop 1.7 - https://devdocs.prestashop.com/1.7/modules/concepts/hooks/list-of-hooks/
