ModuleAdminController | createTemplate() 'Unable to load template file'

[dylanwijnen1]

Hey there,

 

I'm developing a module and I am trying to use a custom template as its done in the product section from prestashop.

 

Looking at the code it shows the following code to use a custom template for different tabs:

this controller extends AdminController

if (method_exists($this, 'initForm'.$this->tab_display))
   $this->tpl_form = strtolower($this->tab_display).'.tpl';

$this->tpl_form_vars['custom_form'] = $data->fetch();

My code is the following placed inside the initContent method

And I am extending ModuleAdminController

    public function initContent()
    {
        if ($this->display == 'edit' || $this->display == 'add')
        {            
            $this->fields_form = array();
            $this->tpl_form = "my_form.tpl";
            
            $this->initMyForm();
        }
        
        parent::initContent();
    }

    public function initMyForm()
    {
        if (!$this->default_form_language)
                $this->getLanguages();

        $data = $this->context->smarty->createTemplate($this->tpl_form);
        
        //echo $this->getTemplatePath().$this->override_folder.$this->tpl_form;
        //echo "<pre>".print_r($data, true)."</pre>";
        //exit;
        
        $data->assign('languages', $this->_languages);
        $data->assign('default_form_language', $this->default_form_language);

        $data->assign('ad', dirname($_SERVER['PHP_SELF']));
        $data->assign('id_lang', $this->context->language->id);
        $data->assign('token', $this->token);
        $data->assign($this->tpl_form_vars);
        $data->assign('link', $this->context->link);
        //When fetching throws the following : Fatal error: Uncaught exception 'SmartyException' with message 'Unable to load template file
        $this->tpl_form_vars['custom_form'] = $data->fetch();
    }

I've double checked the path to the template which ModuleAdminController uses to create the template it is correct.

Yet when trying to display with $data->display(); it throws the exception described in the code above.

 

I'd rather not use the default $fields_form variable due to custom functionality I want in the backoffice.

Any help is appreciated, thanks in advance.

*EDIT*

After looking around I found the directory isn't added to smarty and prestashop ModuleAdminController doesn't do it itself. Fixed by adding this code

$this->context->smarty->addTemplateDir($this->getTemplatePath().$this->override_folder);
