Prestashop 模块管理控制器页面未找到

如何解决Prestashop 模块管理控制器页面未找到

我想弄清楚如何在后台使用控制器。
我使用的 prestashop 版本是 1.7.7.4。
我想在后台创建一个页面。
我在“/modules/MyModule/controllers/admin/MyModuleController.PHP”中创建了一个控制器“MyModuleController”，但在后台出现消息“控制器 MyModuleController 缺失或无效"。
我究竟做错了什么？下面是我写的代码：

/modules/MyModule/MyModule.PHP

<?PHP

class MyModule extends Module
{
    public function __construct()
    {

        $this->name = 'MyModule';
        $this->tab = 'administration';
        $this->version = '1.0.0';
        $this->author = 'Firstname Lastname';
        $this->need_instance = 0;
        $this->ps_versions_compliancy = [
            'min' => '1.6','max' => _PS_VERSION_
        ];
        $this->bootstrap = true;

        parent::__construct();

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

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

    }

    public function install()
    {
         // Install Tabs
        $tab = new Tab();
        $tab->active = 1;
        $tab->class_name = "MyModuleController";
        $tab->module = 'mymodule';
        $tab->name = array();
        $tab->id_parent = (int)Tab::getIdFromClassName('SELL');
        $tab->position = 3;
        foreach ($lang as $l) {
            $tab->name[$l['id_lang']] = $this->l('Mon module');
        }

        $tab->add();

        parent::install();
    }

    public function uninstall()
    {
        // Uninstall Tabs
        $tab = new Tab((int)Tab::getIdFromClassName('Mymodule'));
        $tab->delete();

        // // Uninstall Module
        parent::uninstall();
    }
}

/modules/MyModule/controllers/admin/MyModuleController.PHP

<?PHP
class MyModuleController extends ModuleAdminController
{
    public function __construct()
    {
        parent::__construct();
        $this->bootstrap = true;
        $this->id_lang = $this->context->language->id;
        $this->default_form_language = $this->context->language->id;
    }

    public function initContent()
    {
        parent::initContent();
        return echo 'hello';
    } 
}
?>

解决方法

遵循 Prestashop 默认模块：

模块 ps_linklist：

$this->name = 'ps_linklist';
    $this->author = 'PrestaShop';
    $this->version = '3.2.0';
    $this->need_instance = 0;
    $this->tab = 'front_office_features';
    $this->tabs = [
        [
            'class_name' => 'AdminLinkWidget','visible' => true,'name' => 'Link Widget','parent_class_name' => 'AdminParentThemes',],];

您的管理员控制器的名称必须以“Admin”开头
