Feature: #102159 - Support additional parameters for TCA slug prefix userFunc 

Description 

TCA slug prefix user functions now receive the full TCA field configuration and the field name as additional parameters.

User function implementation 

The prefix user function receives two additional keys alongside the existing parameters:

• fieldName - The name of the slug field
• config - The full TCA configuration array of the slug field

namespace MyExtension\Utility;

class SlugUtility
{
    public function generatePrefix(array $parameters): string
    {
        // Standard parameters (always available)
        $site = $parameters['site'];
        $languageId = $parameters['languageId'];
        $table = $parameters['table'];
        $row = $parameters['row'];

        $fieldName = $parameters['fieldName'];
        $config = $parameters['config'];

        return '/default/';
    }
}

Available parameters 

The user function receives an array with the following keys:

• site - The current site object
• languageId - The current language ID (int)
• table - The table name (string)
• row - The current record data (array)
• fieldName - The name of the slug field (string)
• config - The full TCA configuration array of the slug field

Impact 

Extension developers can access the complete TCA field configuration and the field name inside prefix user functions.
