Friendly URL problem in front module

[Adib Aroui]

I am building a front module for a website that is using `301 Moved Permanently` option in `SEO and URLs` configuration. Wesbite uses Prestashop 1.6.1.9.

In module, I am defining the route like this:

public static $ModuleRoutes = array( 
  'module-aacategories-viewmapping-mapping' => array(
  'controller' => 'viewmapping',
  'rule' => 'mappings{/:tree}', 
  'keywords' => array( 'tree' => array('regexp' => '[/_a-zA-Z0-9-\pL]*', 'param' => 'tree'), ), 
  'params' => array( 
      'fc' => 'module', 
      'module' => 'aacategories', ) 
  )
);

In browser address bar, when I enter:

Quote

site.local/en/mappings/test-map/first-test

I get:

Quote

Please use the following URL instead:

site.local/en/index.php?controller=viewmapping&tree=test-map%2Ffirst-test&module=aacategories

This latter link gives 404. However, when I append `&fc=module` to the url, it goes to desired page.

The problems:

1- How to force Prestashop routing to append `&fc=module` at the end?

2- How to keep the friendly url in address bar and not be redirected?

Note: When I change configuration in SEO and URLs to no redirection, then it works. But it is not the configuration needed in prod.

Your help is much appreciated. Thanks in advance.

I was mistakenly declaring $php_self property in my module front controller.

This property is used in FrontController.php to decide which is the URL.

Thanks for your time guys.
