Form Requests

Classic Laravel 5 form request validation (opens new window).

Once you generated the module using Twill's CLI module generator, it will also prepare the App/Http/Requests/Admin/ModuleNameRequest.php for you to use. You can choose to use different rules for creation and update by implementing the following 2 functions instead of the classic rules one:

<?php

public function rulesForCreate()
{
    return [];
}

public function rulesForUpdate()
{
    return [];
}

There is also an helper to define rules for translated fields without having to deal with each locales:

<?php

$this->rulesForTranslatedFields([
 // regular rules
], [
  // translated fields rules with just the field name like regular rules
]);

There is also an helper to define validation messages for translated fields:

<?php

$this->messagesForTranslatedFields([
 // regular messages
], [
  // translated fields messages
]);

Once you defined the rules in this file, the UI will show the corresponding validation error state or message next to the corresponding form field.

Validating repeater fields

To validate repeater fields added to your model you can reuse the same rulesForCreate and rulesForUpdate methods.

If your repeater is named accordion_item and you want to add validation to the headline field you can use:

public function rulesForCreate()
{
    return ['repeaters.accordion_item.*.header' => 'required'];
}

Alternatively if your field is translatable you can use the helpers as defined above:

public function rulesForUpdate()
{
    return $this->rulesForTranslatedFields([], [
        'repeaters.accordion_item.*.header' => 'required'
    ]);
}
