[SOLVED] parent::initContent() Not working, getting only .tpl content

[Rycka]

Hello,

I'm learning how to create PrestaShop module, by it's Documentation here: https://devdocs.prestashop-project.org/1.7/modules/creation/displaying-content-in-front-office/

I saw dozens of posts like this, and there is no SOLUTION??? Does this mean PS Documentation is lying?!

My Controller Front-end page is not embedding with main theme, which parent::initContent() should do, but it's doing NOTHING... I'm just seeing 'This is my view' of my display.tpl in white screen, no main theme content. Debug mode shows no errors, and yes I deleted my cache, set to force Template Compilation, tried dozens of "SOLUTIONS", and nothing...

Here's my code:

Try add to __construct() this line:

$this->controllers = array('display');

so it should looks like:

public function __construct() {
        $this->name = 'manomodulis';
        $this->tab = 'front_office_features';
        $this->version = '1.0';
        $this->author = 'Rytis Plečkauskas';
        $this->need_instance = 0;
	$this->controllers = array('display');
        $this->ps_versions_compliancy = [
            'min' => '1.6',
            'max' => _PS_VERSION_
        ];
        $this->bootstrap = true;

        parent::__construct();

        $this->displayName = $this->l('Mano Modulis');
        $this->description = $this->l('Mano pirmas PrestaShop modulis.');

        $this->confirmUninstall = $this->l('Ar tikrai nori ištrinti šitai?!?');

        if (!Configuration::get('MANOMODULIS_ARGERAS')) {
            $this->warning = $this->l('No name provided');
        }
    }

Hi, endriu107, thanks for your response, but however it's still not working.

[endriu107]

There is more errors like:

class manomodulisdisplayModuleFrontController extends ModuleFrontController

should be: 

class manomodulisDisplayModuleFrontController extends ModuleFrontController

[endriu107]

Inside file modules\manomodulis\views\templates\front\display.tpl content should be like this:

{extends file='page.tpl'}

{block name='page_content'}
THERE CONTENT TO DISPLAY
{/block}

Thank you endriu107, that worked. I tried these solutions before, but I didn't had this line: $this->controllers = array('display'); Looks like everything together got it working. Thanks again.
