Adding New field in PrestaShop 1.7 Admin Symfony Controller

In this blog, we are going to learn how to modify existing Symfony controller forms in PrestaShop.

In PrestaShop 1.7.x.x, the system has changed as we now rely on the Symfony Form component and can modify existing forms without template override.

So let’s understand how to add new fields and modify/remove existing fields. For this purpose we’ll use action<ClassName>FormBuilderModifier hook.

Suppose, we want to modify the customer form then we have to use the actionCustomerFormBuilderModifier hook.

Let’s be practical…

1) Modify and remove existing fields

Here we’ll remove the First name field and will modify the Last name field’s of the customer form

Current view of the form:

In the hook function, this is the example code 

public function hookActionCustomerFormBuilderModifier($params)
{
     /** @var $formBuilder \Symfony\Component\Form */
     $formBuilder = $params['form_builder'];
     $formBuilder->remove('first_name');
     $formBuilder->get('last_name')->setRequired(false);
 }

As we can see, the First name has been removed and the Last name field has been modified to a non-required field.

2) Add a new field

Now, we’ll add Mobile Number Field just after the Email field

public function hookActionCustomerFormBuilderModifier($params)
{
    /** @var $formBuilder \Symfony\Component\Form */
    $formBuilder = $params['form_builder'];
    $formBuilder->remove('first_name');
    $formBuilder->get('last_name')->setRequired(false);
    $allFields = $formBuilder->all();
    foreach ($allFields as $inputField => $input) {
        $formBuilder->remove($inputField);
    }
    foreach ($allFields as $inputField => $input) {
        $formBuilder->add($input);
        if ($inputField == 'email') {
            /** @var TextType::class \Symfony\Component\Form\Extension\Core\Type\TextType */
            $formBuilder->add(
                'mobile_number', 
                 TextType::class, 
                 ['label' => 'Mobile Number']
            );
        }
     }
  }

Hence, the text type field is created so we have to use namespace use Symfony\Component\Form\Extension\Core\Type\TextType;  in the module.

Methods of formBuilder class can be seen from these two files

i)<prestashop_root_directory>/vendor/symfony/symfony/src/Symfony/Component/Form/FormBuilderInterface.php

ii)<prestashop_root_directory>/vendor/symfony/symfony/src/Symfony/Component/Form/FormBuilder.php

Note: 

1) Here, we have modified only the view of the form. To save data of new fields, use these hooks

i) actionObject<ClassName>AddAfter

ii) actionObject<ClassName>UpdateAfter

2) If action<ClassName>FormBuilderModifier hook is not supported in some PrestaShop’s versions then the same functionality can be achieved by template override.

That’s all about this blog.
