Prestashop模塊支付鉤不觸發

Prestashop 1.6.1.6需要在支付鉤子中進行一些API調用。但是由於某些原因，鉤子沒有觸發，並且hookPayment方法沒有執行。當與具有hookPayment的PayPal模塊比較時，該鉤子被執行。我做錯了什麼？Prestashop模塊支付鉤不觸發

模塊代碼儘可能

<?php

如果（定義（ '_ PS_VERSION_'）！）出口一樣簡單;

類TestModule擴展模塊{

public function __construct() { 
    $this->name = 'testmodule'; 
    $this->tab = 'shipping_logistics'; 
    $this->version = '1.0.0'; 
    $this->author = 'Firstname Lastname'; 
    $this->need_instance = 0; 
    $this->ps_versions_compliancy = array('min' => '1.6', 'max' => _PS_VERSION_); 
    $this->bootstrap = true; 

    parent::__construct(); 

    $this->displayName = $this->l('Test Module'); 
    $this->description = $this->l('Description of my module.'); 

    $this->confirmUninstall = $this->l('Are you sure you want to uninstall?'); 
} 

public function install() { 
    if (!parent::install() || !$this->registerHook('payment')) 
     return false; 
    return true; 
} 

public function uninstall() { 
    if (!parent::uninstall()) 
     return false; 
    return true; 
} 

public function hookPayment($params) { 
    ddd($params); 
} 

}

安裝鉤子後在數據庫

mysql> select * from module where id_module=75; 
+-----------+------------+--------+---------+ 
| id_module | name  | active | version | 
+-----------+------------+--------+---------+ 
|  75 | testmodule |  1 | 1.0.0 | 
+-----------+------------+--------+---------+ 
1 row in set (0,00 sec) 

mysql> select * from hook_module where id_module=75; 
+-----------+---------+---------+----------+ 
| id_module | id_shop | id_hook | position | 
+-----------+---------+---------+----------+ 
|  75 |  1 |  1 |  4 | 
+-----------+---------+---------+----------+ 
1 row in set (0,00 sec) 

mysql> select * from hook where id_hook=1; 
+---------+----------------+---------+-----------------------------------------------------+----------+-----------+ 
| id_hook | name   | title | description           | position | live_edit | 
+---------+----------------+---------+-----------------------------------------------------+----------+-----------+ 
|  1 | displayPayment | Payment | This hook displays new elements on the payment page |  1 |   1 | 
+---------+----------------+---------+-----------------------------------------------------+----------+-----------+ 
1 row in set (0,00 sec)
