PrestaShop Canvas Module

PrestaShop Canvas Module

This tutorial is about PrestaShop Canvas Module . This is a quite useful piece of code and a very important one too. let’s move forward and have a look.

First Step:

Create a directory as the same name as your module name in the following directory.


In my case, my module name is helloworld so directory name will be helloworld. The directory structure will look like.


Second Step

Now we create file name helloworld.php in the following location. You module directory name and file name must be same.


The file contains following code.


if (!defined('_PS_VERSION_'))

class Helloworld extends Module
  private $errors = null;
  public function __construct()
    // Author of the module
    $this->author = 'qaisarsatti';
    // Name of the module ; the same that the directory and the module ClassName
    $this->name = 'helloworld';
    // Tab where it's the module (administration, front_office_features, ...)
    $this->tab = 'others';
    // Current version of the module
    $this->version = '1.0.0';
    //  Min version of PrestaShop wich the module can be install
    $this->ps_versions_compliancy['min'] = '1.5';
    // Max version of PrestaShop wich the module can be install
    $this->ps_versions_compliancy['max'] = '1.7';
    // OR $this->ps_versions_compliancy = array('min' => '1.5', 'max' => '1.6');
    //  The need_instance flag indicates whether to load the module's class when displaying the "Modules" page
    //  in the back-office. If set at 0, the module will not be loaded, and therefore will spend less resources
    //  to generate the page module. If your modules needs to display a warning message in the "Modules" page,
    //  then you must set this attribute to 1.
    $this->need_instance = 0;
    // Modules needed for install
    $this->dependencies = array();
    // e.g. $this->dependencies = array('blockcart', 'blockcms');
    // Limited country
    $this->limited_countries = array();
    // e.g. $this->limited_countries = array('fr', 'us');
    // Name in the modules list
    $this->displayName = $this->l('Example');
    // A little description of the module
    $this->description = $this->l('Module Example');
    // Message show when you wan to delete the module
    $this->confirmUninstall = $this->l('Are you sure you want to delete this module ?');
    if ($this->active && Configuration::get('EXAMPLE_CONF') == '')
      $this->warning = $this->l('You have to configure your module');
    $this->errors = array();

So, that’s it from this tutorial. I strongly believe there is always room for improvement. So I am open for any suggestion and feedback. Please feel free to leave hat you are thinking in the comments section below. Cheers.
