When the hook actionAdminDeleteAfter is triggered

[Peter_17]

Hi,

when those hooks are triggerd? Prestashop 8.1.6.

actionAdminDeleteAfter
actionAdminDeleteBefore
actionAdminProductsControllerDeleteAfter
actionAdminProductsControllerDeleteBefore

I guess that when I delete a product in BO.
/adminstrator/index.php/sell/catalog/products-v2

I can install a module with any of this hook but function connected with any of this hooks is not executed when I delete a product.

Why?

In the same module I successfully used a hook actionAdminDuplicateAfter

How else should I execute a function after product deletion?

A test module for the hook:

At least it should show an error because $PCDA is not defined.

<?php

declare(strict_types=1);

 

if (!defined('_PS_VERSION_')) {

exit;

}

 

class DhPcda extends Module

{

public function __construct()

{

$this->name = 'dhpcda';

$this->tab = 'administration';

$this->version = '1.0.0';

$this->author = 'aaa.pl';

$this->need_instance = 0;

$this->ps_versions_compliancy = [

'min' => '1.8.0.0',

'max' => _PS_VERSION_,

];

$this->bootstrap = true;

 

parent::__construct();

 

$this->displayName = $this->trans('AAA PCDA', [], 'Modules.Dhtestduplicate.Dhtestduplicate');

$this->description = $this->trans('Test: ActionAdminProductsControllerDeleteAfter', [], 'Modules.Dhtestduplicate.dhtestduplicate');

}

 

public function install()

{

if (Shop::isFeatureActive()) {

Shop::setContext(Shop::CONTEXT_ALL);

}

return parent::install() &&

$this->registerHook('actionAdminProductsControllerDeleteAfter');

 

}

 

public function uninstall()

{

return parent::uninstall();

}

 

public function isUsingNewTranslationSystem()

{

return true;

}

 

public function hookActionAdminProductsControllerDeleteAfter($params) {

 

$aaa = $PCDA;

file_put_contents("../modules/pcda/dev_logs/array_params_PCDA.json",json_encode($params));

$db = \Db::getInstance();

}

 

}

Hi,

Here are few Debugging tips:

• Add a log entry at the beginning of the hook method to check if the method is called at all.
• Make sure the file path where you are trying to write the logs is correct and writable.
• Navigate to the product deletion page and delete a product. Then check the logs to see if the hooks are being triggered.

Thanks!

You could use object hook, it works like this action<yourobjectname>DeleteAfter. In your case this will be actionProductDeleteAfter. This hook will be called after product is deleted.

[Peter_17]

Thanks for help.

The hook actionProductDeleteAfter is not called after product deletion. This is the same situation as with hooks:
actionAdminDeleteAfter
actionAdminDeleteBefore
actionAdminProductsControllerDeleteAfter
actionAdminProductsControllerDeleteBefore
and
actionAdminProductDeleteAfter

I checked that I can use other hooks like actionCategoryUpdate, actionListModules, actionAdminDuplicateAfter.
For example the function hookActionCategoryUpdate is called correctly and json file is written to the directory.

I tested it on the local installation and on the hosting configured for Prestashop.

Are you sure its registered correctly? Because Object hooks are allways called after save,add,delete action.
Edit:
Here is proper way, i'm using it myself but on PS 1.7.8
public function hookactionObjectProductDeleteBefore($params){

On PS 1.7.8 this code works (json files are saved):

    public function install()  
    {
 
        return parent::install() &&
            $this->registerHook('actionObjectProductDeleteAfter') &&
            $this->registerHook('actionObjectProductDeleteBefore');

    }

    public function hookactionObjectProductDeleteAfter($params) {
          
        file_put_contents("../modules/testduplicate/dev_logs/array_params_after.json",json_encode($params));
        
    }

    public function hookactionObjectProductDeleteBefore($params) {
          
        file_put_contents("../modules/testduplicate/dev_logs/array_params_before.json",json_encode($params));
        
    }
    }

but it does not work on PS 8.1.6

Which hooks should I use on PS 8.1.6?

Maybe the problem is file_put_contents function? Try to use built in prestashop logger.
PrestaShopLogger::addLog('actionObjectProduct '.json_encode($params));

    public function delete()
    {
        // @hook actionObject<ObjectClassName>DeleteBefore
        Hook::exec('actionObjectDeleteBefore', ['object' => $this]);
        Hook::exec('actionObject' . $this->getFullyQualifiedName() . 'DeleteBefore', ['object' => $this]);

        $this->clearCache();
        $result = true;
        // Remove association to multishop table
        if (Shop::isTableAssociated($this->def['table'])) {
            $id_shop_list = Shop::getContextListShopID();
            if (count($this->id_shop_list)) {
                $id_shop_list = $this->id_shop_list;
            }

            $id_shop_list = array_map('intval', $id_shop_list);

            $result &= Db::getInstance()->delete($this->def['table'] . '_shop', '`' . $this->def['primary'] . '`=' .
                (int) $this->id . ' AND id_shop IN (' . implode(', ', $id_shop_list) . ')');
        }

        // Database deletion
        $has_multishop_entries = $this->hasMultishopEntries();

        // Database deletion for multilingual fields related to the object
        if (!empty($this->def['multilang']) && !$has_multishop_entries) {
            $result &= Db::getInstance()->delete($this->def['table'] . '_lang', '`' . bqSQL($this->def['primary']) . '` = ' . (int) $this->id);
        }

        if ($result && !$has_multishop_entries) {
            $result &= Db::getInstance()->delete($this->def['table'], '`' . bqSQL($this->def['primary']) . '` = ' . (int) $this->id);
        }

        if (!$result) {
            return false;
        }

        // @hook actionObject<ObjectClassName>DeleteAfter
        Hook::exec('actionObjectDeleteAfter', ['object' => $this]);
        Hook::exec('actionObject' . $this->getFullyQualifiedName() . 'DeleteAfter', ['object' => $this]);

        return $result;
    }

This is delete function from objectmodel in PS8. So it should work exacly like on ps1.7

Thanks for help.

Searching for a string: 'public function delete()' I found in a file /classes/Product.php a line:

Hook::exec('actionProductDelete', ['id_product' => (int) $this->id, 'product' => $this]);

So I wrote my code this way:

    public function install()
    {   
        return parent::install() &&
        $this->registerHook('actionProductDelete');
    }
    

    public function hookactionProductDelete($params)
    {
          
        file_put_contents("../modules/testduplicate/dev_logs/array_params_APD.json",json_encode($params));

        PrestaShopLogger::addLog('hookactionProductDelete'.json_encode($params));     
        
    }

and it works

I guess it's not 100% the same hook as 'actionProductDeleteAfter' but in my module it will work good enough.
