Adding the visual editor to category description the proper way

Open up your Prestashop root folder, then navigate to controllers/admin and open AdminCategorisController.php in your favorite code editor.

Locate the renderForm method, at about line 321 (Prestashop 1.5.4.0). Inside it, locate the following snippet

				array(
					'type' => 'textarea',
					'label' => $this->l('Description:'),
					'name' => 'description',
					'lang' => true,
					'rows' => 10,
					'cols' => 100,
					'hint' => $this->l('Invalid characters:').' <>;=#{}',
				),

Change so it looks like this:

				array(
					'type' => 'textarea',
					'label' => $this->l('Description:'),
					'name' => 'description',
					'lang' => true,
					'rows' => 10,
					'cols' => 100,
					'hint' => $this->l('Invalid characters:').' <>;=#{}',
					'autoload_rte' => true
				),

As you can see we have added ‘autoload_rte’ => true. This enables the visual editor. Save and access a category page in the back office to see the visual editor.

However, this way your changes will inevitably be overrridden at the next prestashop update you do. We need to use an override.

Using an override for the controller

Back to your prestashop root, go to override/controllers/admin and create a file called AdminCategorisController.php. Paste the following snippet inside

Change so it looks like this:

<?php

Class AdminCategoriesController extends AdminCategoriesControllerCore
{

?>

Note: We are extending a prestashop class (controller in this case). If you want to know more about this, head over here.

In the original AdminCategoriesController, copy the whole renderForm function we just modified, and paste it inside our new override.

Okay, at this point you might notice that the method is calling parent::renderForm(); at the end, right before the closing bracket. Therefore, change the following line

return parent::renderForm();

to

return AdminController::renderForm();

Tip: if we didn’t do this, the original one would have overridden this one no matter what, and no changes would have taken place

Lastly, head over to the root folder again then cache/ and delete the class_index.php file, so that our changes take place. At this point, you can also restore the original adminCategoriesController to its defaults, since we are extending it in a maintainable way.

Here is the complete override (you can download it as a project file)

…And! if you would like more freedom with the visual editor, or simply the possibility to add html / javascript / css content everywhere in Prestashop/s front office, have a look at my module HTML Block!
