Unable to install customtax module. The form is invalid and cannot be loaded.

[Cristian Capannini]

Hi i've create module to manage tax with table and admin interface.

The structure is:

/modules
   /ps_customtax
       ps_customtax.php
       customtax.tpl
       customtax.php
       /controllers
            /admin
               AdminCustomTaxController.php

The module to install appear in the admin panel but cannot install. Tried to put message to identify errors.
Can you help me for prestashop 8.1.0?
Thanks.

Hello,

There are multiple issues with the module. PrestaShop has a free module validator, where you can check as well: https://validator.prestashop.com/ (you need to check the Compatibility tab)

But, basically, in order to fix it, you need to do the following:
- rename the folder to 'customtax'
- rename the ps_customtax.php file to customtax.php
- rename the class from Ps_CustomTax to CustomTax
- remove the Tools::displayWarning calls

You should be able to install it at this point.

Your module is very non-compliant, causing errors.
The above link is the link to the official website to generate the DEMO module. It is recommended that you generate a test module, compare it carefully, and make corrections one by one.
