Module overriding class. Problem when reinstall. ReflectionException

[serralta]

Hi everybody.

 

I am trying to develop an easy module. It is my first one, so it may be some stupid problem but the fact is I'm stuck with it from some days ago.

 

I have a simple module that has a override/classes/Product.php class. It adds a simple single method. When I install it, all is fine. The overriden Product class is generated.

 

The problem is when I do some changes and I try to reinstall it (reseting it or uninstalling and installing, again, the result is the same). The method I added to the overriden class is not deleted completly when I uninstall the module. Only the name is removed but not the function body.

 

This causes a Fatal error: Uncaught exception 'ReflectionException' with message 'Class ProductOverrideOriginal_remove539defbda2a6c does not exist'

 

I paste the generated code.

 

When I install the module for first time I got:

class Product extends ProductCore {
	public function getLocalizationImage(Context $context = null)
	{
		return true;
	}  
}

When I reinstall it, or uninstall it the classe is left as follows:

class Product extends ProductCore {
	{
		return true;
	}  
}

Is it normal? What am I missing? The same problem if I do a second module that adds a DIFFERENT function to the Produt class. The second module I install has no name in its function declarations.

 

Any help would be appreciate.

Thanks!

hi,

 

delete all your file overrided in www/override

and read www/override/readme_override.txt which tel :

in order to reinstate the default behavior, you must delete the /cache/class_index.php file

I don't think delete /cache/class_index.php file would solve the problem.

 

I've found this workaround here

http://stackoverflow.com/questions/18996528/how-to-remove-override-when-uninstalling-the-module-in-prestashop

 

not a perfect solution but you have to manually remove any file generated in override directory.

 

still looking forward to better elegant solution.

What is in your "uninstall()" method?

Hi, this is my code for uninstall method:

    public function uninstall()
    {
        Configuration::deleteByName('PECSDIFIELDS_SHOW_REDLABEL');
        include(dirname(__FILE__).'/sql/install.php');

        return parent::uninstall();
    }

Hi,

I solved my problem, my mistake was in the class I was overriding; here I found the right way to create the override.
