Prestashop: Mostrar el editor TinyMCE en la descripción de las categorías

En la descripción de las categorías de Prestashop, el editor TiniMCE viene desactivado (vete tú a saber por qué…) así que aquí os dejo un truco para poder activarlo en Prestashop 1.5.

Debemos sobreescribir la clase AdminCategoriesController. Para ello creamos el archivo AdminCategoriesController.php en la carpeta /override/controllers/admin.

Siempre trataremos de evitar modificar los archivos del core de Prestashop, así de paso, si algo del código no funciona y la tienda se te va al garete, borras el archivo y listo.

En ese archivo, copiamos el código del método renderForm del controlador original. El truco para activar el editor visual es buscar este trozo de texto:

[codesyntax lang=»php»]

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

[/codesyntax]

Y añadir la línea que activa el editor al final:

[codesyntax lang=»php»]

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

[/codesyntax]

el código completo del archivo AdminCategoriesController.php sería el siguiente:

[codesyntax lang=»php»]
