1.7.6 : ajout de champ dans fiche client backend

[Grazulex]

bonjour,

depuis des jours je me bas pour afficher des champs supplémentaires dans la fiche client dans la backend depuis un nouveau module de paiement que je dois faire.

j'ai tout essayer, le hook, l'override,...rien n'y fait.

je suis en mode multi-boutiques.

voici mon code actuel.

<?php

if (!defined('_PS_VERSION_')) {
    exit;
}

class Facture extends PaymentModule
{
    public $hooks = [
        'actionAdminCustomersFormModifier',
        'actionAdminCustomersControllerSaveAfter',
        'paymentOptions',
        'paymentReturn',
    ];

    public function __construct()
    {

        $this->need_instance = 0;
        $this->ps_versions_compliancy = [
            'min' => '1.7.0',
            'max' => _PS_VERSION_
        ];
        $this->controllers = [
            'payment',
            'validation'
        ];

        parent::__construct();

        $this->displayName = $this->l('Facture Mensuelle');
        $this->description = $this->l('Paiement via facture mensuelle');
    }
