addCSS and addJS not working

ralfillo · April 11, 2016

Hi guys,

I'm following a module creation book, however when I try to do addCss ( and JS ) in the CSS and the JS files don't appear in the <head>.

This is the file mymodcomments.php

<?php

class MyModComments extends Module{

public function __construct(){

$this->name = 'mymodcomments';

$this->tab = 'front_office_features';

$this->version = '0.1';

$this->author = 'Just Me';

$this->bootstrap = true;

parent::__construct();

$this->displayName = $this->l('My Module of product comments');

$this->description = $this->l('With this module, your customers will be able to grade and comments your products');

}

public function processConfiguration(){

if (Tools::isSubmit('mymod_pc_form')){

$enable_grades = Tools::getValue('enable_grades');

$enable_comments = Tools::getValue('enable_comments');

Configuration::updateValue('MYMOD_GRADES', $enable_grades);

Configuration::updateValue('MYMOD_COMMENTS', $enable_comments);

$this->context->smarty->assign('confirmation', 'ok');

}

public function assignConfiguration()

{

$enable_grades = Configuration::get('MYMOD_GRADES');

$enable_comments = Configuration::get('MYMOD_COMMENTS');

$this->context->smarty->assign('enable_grades', $enable_grades);

$this->context->smarty->assign('enable_comments',

$enable_comments);

}

public function getContent(){

$this->processConfiguration();

$this->assignConfiguration();

return $this->display(__FILE__, 'getContent.tpl');

}

public function install(){

parent::install();

$this->registerHook('displayProductTabContent');

return true;

$this->registerHook('header');

}

public function processProductTabContent(){

if (Tools::isSubmit('mymod_pc_submit_comment')){

$id_product = Tools::getValue('id_product');

$grade = Tools::getValue('grade');

$comment = Tools::getValue('comment');

$insert = array(

'id_product' => (int)$id_product,

'grade' => (int)$grade,

'comment' => pSQL($comment),

'date_add' => date('Y-m-d H:i:s'),

);

Db::getInstance()->insert('mymod_comment', $insert);

$this->context->smarty->assign('new_comment_posted', 'true');

}

public function assignProductTabContent(){

$enable_grades = Configuration::get('MYMOD_GRADES');

$enable_comments = Configuration::get('MYMOD_COMMENTS');

$id_product = Tools::getValue('id_product');

$comments = Db::getInstance()->executeS('SELECT * FROM

'._DB_PREFIX_.'mymod_comment WHERE id_product =

'.(int)$id_product);

$this->context->controller->addCSS($this->_path . 'views/css/

mymodcomments.css', 'all');

$this->context->controller->addJS($this->_path . 'views/js/

mymodcomments.js');

$this->context->smarty->assign('enable_grades', $enable_grades);

$this->context->smarty->assign('enable_comments',

$enable_comments);

$this->context->smarty->assign('comments', $comments);

}

public function hookDisplayProductTabContent($params){

$this->processProductTabContent();

$this->assignProductTabContent();

return $this->display(__FILE__, 'displayProductTabContent.tpl');

}

?>

I created both files (mymodcomments.css and mymodcomments.js) in the right path.

I've been trying to fix this problem for hours but I can't find the solution, I'd really appreciate your help.

Thanks!

hello

i did it before as this way

first add $this->registerHook('header') in public function install of ur module then add $this->context->controller->addJS($this->_path . 'views/js/

mymodcomments.js'); in public function hookHeader(). (for appear ur css or js in head)

see blocktopmenu module for example.

Hi lexical_error,

I just did the changes that you recommended me but it's still not working

Do you have any other ideas?

Thanks

lexical_error · April 11, 2016

addcss and addjs should be in hookHeader function

public function hookHeader()

{

$this->context->controller->addCSS($this->_path . 'views/css/

mymodcomments.css', 'all');

$this->context->controller->addJS($this->_path . 'views/js/

mymodcomments.js');

}

Finally I coped most of the code from the repository from the book: https://github.com/FabienSerny/mymodcomments/commit/df34711810227e95177e07836b002d63530f0832

I adjusted it a bit and it works, it's a pity that I don't understand why wasn't working before

<?php


class MyModComments extends Module{


public function __construct(){
$this->name = 'mymodcomments';
$this->tab = 'front_office_features';
$this->version = '0.1';
$this->author = 'Just Me';
$this->bootstrap = true;
parent::__construct();
$this->displayName = $this->l('My Module of product comments');
$this->description = $this->l('With this module, your customers will be able to grade and comments your products');
}


public function install(){
  parent::install();
  $this->registerHook('displayProductTabContent');
  return true;
  }


public function processProductTabContent(){
     if (Tools::isSubmit('mymod_pc_submit_comment')){
 $id_product = Tools::getValue('id_product');
 $grade = Tools::getValue('grade');
 $comment = Tools::getValue('comment');
 $insert = array(
'id_product' => (int)$id_product,
'grade' => (int)$grade,
'comment' => pSQL($comment),
'date_add' => date('Y-m-d H:i:s'),
);
 Db::getInstance()->insert('mymod_comment', $insert);
 $this->context->smarty->assign('new_comment_posted', 'true');
     }
} 


public function assignProductTabContent()
  {
  $enable_grades = Configuration::get('MYMOD_GRADES');
  $enable_comments = Configuration::get('MYMOD_COMMENTS');


  $id_product = Tools::getValue('id_product');
  $comments = Db::getInstance()->executeS('
   SELECT * FROM `'._DB_PREFIX_.'mymod_comment`
   WHERE `id_product` = '.(int)$id_product);


  $this->context->controller->addCSS($this->_path.'views/css/mymodcomments.css', 'all');
  $this->context->controller->addJS($this->_path.'views/js/mymodcomments.js');


   $this->context->smarty->assign('enable_grades', $enable_grades);
   $this->context->smarty->assign('enable_comments', $enable_comments);
   $this->context->smarty->assign('comments', $comments);
  }


public function hookDisplayProductTabContent($params){
  $this->processProductTabContent();
  $this->assignProductTabContent();
  return $this->display(__FILE__, 'displayProductTabContent.tpl');
  }


public function processConfiguration(){
if (Tools::isSubmit('mymod_pc_form')){
$enable_grades = Tools::getValue('enable_grades');
$enable_comments = Tools::getValue('enable_comments');
Configuration::updateValue('MYMOD_GRADES', $enable_grades);
Configuration::updateValue('MYMOD_COMMENTS', $enable_comments);
$this->context->smarty->assign('confirmation', 'ok');
}
   }

}

?>

Thank you very much. I have the same book and get the same error. Now is the error resolved with your hint

Hello, I also encountered the same problem. CSS and JS files were not imported into the page. Following the previous advice I added a hookHeader function :

    public function hookHeader()
    {
        $this->context->controller->addCSS($this->_path . 'views/css/mymodcomments.css', 'all');
        $this->context->controller->addJS($this->_path . 'views/js/mymodcomments.js');

    }

And I added this function in my install() function. I reset my module and great! It works!

    public function install()
    {
        parent::install();
        $this->registerHook('displayProductTabContent');
        $this->registerHook('header');

        return true;
    }

Thanks for your advice!

Denis

Check this: https://devdocs.prestashop-project.org/8/themes/getting-started/asset-management/

ps8modules.com · June 29, 2023

hookHeader is not supported in new versions of Prestashop. Use hookDisplayHeader. Next, run your css and js only on certain pages.

ps8modules.com · June 29, 2023

public function hookDisplayHeader()
{
  if (in_array( $this->context->controller->controller_name, array('index','category', 'product')) {
    addcss and js}
}
