Module - controller is never recognised

[Ikoshop]

Prestashop 8.2, trying to add a controller to a module.

File, called AdminYourCustomController.php in the controllers/admin directory of the module. Defined as 

class AdminYourCustomController extends ModuleAdminController{...}

called from my module

            $this->context->smarty->assign([
                'my_url' => $this->context->link->getAdminLink('AdminYourCustomController', true, [], ['action' => 'synchronizeProducts']),
            ]);

module uninstalled, reinstalled, cache cleared, read/write rights to the controller file checked and the controller is not recognised when called either by getAdminLink or a direct call to the URL of the controller.

I've seen on some old posts that a tab needed to be added and initialised in the install() method. I tried this but it didn't do anything.

Does anyone have a working solution for adding a controller in 8.2 ?

Yes, you need to add tab in installation function like this:

        // add admin cotroller support
        if (!$this->existsTab($this->tab_class)) {
            if (!$this->addTab($this->tab_class, -1)) {
                return false;
            }
        }
        // #add admin cotroller support

    public function existsTab($tab_class)
    {
        $result = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('SELECT id_tab AS id
        FROM `' . _DB_PREFIX_ . 'tab` t WHERE LOWER(t.`class_name`) = \'' . pSQL($tab_class) . '\'');
        if (count($result) == 0) {
            return false;
        }

        return true;
    }

where $tab_class = 'AdminYourModuleName';

    private function addTab($tab_class, $id_parent)
    {
        $tab = new Tab();
        $tab->class_name = $tab_class;
        $tab->id_parent = $id_parent;
        $tab->module = $this->tab_module;
        $tab->name[(int) Configuration::get('PS_LANG_DEFAULT')] = $this->l('Any simple name for module');
        $tab->add();

        return true;
    }

Link in old form:

$this->context->link->getAdminLink('AdminYourModuleName') . '&ajax=true&id_lang=' . $id_lang

 

[Ikoshop]

Thanks.

I've tried it both your way and another way (see below). The tab gets added to the database but when I try to access the controller it still gives an error every time.

 

    public function install()
    {
        Configuration::updateValue('IKOSTOCK_LIVE_MODE', false);

        include(dirname(__FILE__).'/sql/install.php');

        return parent::install() &&
			$this->installTab() &&
			$this->registerHook('displayDashboardToolbarTopMenu');
    }

    private function installTab()
    {
        $tab = new Tab();
        $tab->class_name = 'AdminYourCustomController';
        $tab->module = $this->name;
        $tab->id_parent = (int) Tab::getIdFromClassName('AdminCatalog'); // Default tab, or use AdminCatalog
        $tab->active = 1;

        foreach (Language::getLanguages(true) as $lang) {
            $tab->name[$lang['id_lang']] = 'Custom Controller';
        }

        return $tab->add();
    }

Try to remove tab before new installation

[Ikoshop]

I just saw your update.

 

            $this->context->smarty->assign([
                'synchronize__url' => $this->context->link->getAdminLink('AdminYourCustomController', true, [], ['action' => 'synchronizeProducts'])  . '&ajax=true&id_lang=' . $this->lang,
            ]);

Like this, I no longer get the controller error, instead I get redirected to 

http://localhost:8081/admin985hli9ksojm6m5owdr/index.php?controller=AdminYourCustomController&action=synchronizeProducts&token=8c99384214334d3313e19be1bc689148&ajax=true&id_lang=1
 

and a page not found error.

removing the tab from the dB and reinstalling doesn't change anything. I don't see a tab displayed anywhere on the product admin screen, despite it being in the database

As I understand, you have working link now. Use it for ajax method in javascript.

Also create methods in your admin controller.

[Ikoshop]

No, I don't have a working link and I cannot get the controller to work. I've tried many other methods, with front and admin controllers, but none of the controllers are found when trying to access them from a direct URL in the format {sitename}/module/{modulename}/{controllername} or 

{sitename}/index.php?controller={AdminControllerName}

There must be something fundamentally wrong with my Prestashop installation as everything that is supposed to work does not when it comes to recognising the existence of controllers.

[webprog]

Check that your controller is in yourmodule\controllers\admin folder

Name - AdminYourModule.php

And have code like this:

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

class AdminYourModuleController extends ModuleAdminController
{
    public function initContent()
    {
        parent::initContent();

....

	}
}

Checked and rechecked lots of times.

I wondered if I needed a vendor/autoload.php file for it to work? I tried to make one with composer but when I load the page which accesses the module it throws the error 

 

Warning: include(/var/www/html/modules/mymodulename/vendor/composer/../composer/InstalledVersions.php): Failed to open stream: No such file or directory

I don't use vendor folder.

So, when you enter this link: http://localhost:8081/admin985hli9ksojm6m5owdr/index.php?controller=AdminYourCustomController&action=synchronizeToPrestaShop&token=8c99384214334d3313e19be1bc689148&ajax=true&id_lang=1

You can see the Return values from your controller, right?

[Ikoshop]

No, I  just see 'page not found'.

For proper functioning, the controller must return the return values. Try this link:

http://localhost:8081/admin985hli9ksojm6m5owdr/index.php?controller=AdminYourCustom&token=8c99384214334d3313e19be1bc689148

without vars and corrected link to controller.

[Ikoshop]

Once again: page not found.

I think I will have to abandon this approach and try find a solution which does not use a controller.

Does anyone have a working solution for adding a controller in 8.2 ?

Make sure the controller is in the correct folder.
It should be as the following:  modules/your-module/src/Controller/AdminYourCustomController.php
It looks like you forgot the /src/ folder.

And maybe you could also share your namespacing and autloader config?
