Logging error messages and exception in PS

[veptune]

Hello,

I have real issues with logging exceptions / messages with Prestashop.

For example I made a module and I got :

The module testa is invalid and cannot be loaded.

So I add some debug stuff, but no messages are displayed in the dev file (debug mode is enabled), even the "exit" has no effect.

   public function __construct()
    {
        $this->name = 'testa';
        $this->version = '1';
        $this->author = 'nico';
        $this->bootstrap = true;
        $this->need_instance = 0;

        try
        {
            parent::__construct();
        }
        catch (Exception $e)
        {
            echo $e->getTraceAsString();
        }
       
        echo Tools::displayError('ÉEEEhec de l\'installation du module.');

        echo "ERROR THERE";
        exit();



}

 

I can do :

 $this->logger = SymfonyContainer::getInstance()->get('logger');
 $this->logger->info(sprintf('[%s] In %s', __CLASS__, __FUNCTION__));

but not in construct

What is the best way to add debug messages and exceptions, wherever in the code?

Thanks

How did to conclude that your module code is being loaded?

Are you able to see the module in the module list in the back office? Is the module enabled from the backend?

Yes, I can see it in the module list. And I got the error when I choose to install it.

I clear cache every time I change something.

Even if I add a typo in the code :

public function __construct()
{

fgfdg

...

I only got "The module testa is invalid and cannot be loaded."

I confirm I'm sure I update the code of this module and not another else.

Then, most probably issue is in the install function, not in the construct function.

Hi,

 

The issue may be due to an incorrect install() function or other implementation problems within your module. I would suggest that you please check the PrestaShop module documentation to ensure it follows the proper standards:

https://devdocs.prestashop-project.org/8/modules/creation/tutorial/ 

 

Also, you can check the custom module generator provided by PrestaShop for reference:
