Form validation
|
||
|
|
========
|
||
|
|
|
||
|
|
`model-form` uses laravel's validation rules to verify the data submitted by the form:
|
||
|
|
|
||
|
|
```php
|
||
|
|
$form->text('title')->rules('required|min:3');
|
||
|
|
|
||
|
|
// Complex validation rules can be implemented in the callback
|
||
|
|
$form->text('title')->rules(function ($form) {
|
||
|
|
|
||
|
|
// If it is not an edit state, add field unique verification
|
||
|
|
if (!$id = $form->model()->id) {
|
||
|
|
return 'unique:users,email_address';
|
||
|
|
}
|
||
|
|
|
||
|
|
});
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also customize the error message for the validation rule:
|
||
|
|
|
||
|
|
```php
|
||
|
|
$form->text('code')->rules('required|regex:/^\d+$/|min:10', [
|
||
|
|
'regex' => 'code must be numbers',
|
||
|
|
'min' => 'code can not be less than 10 characters',
|
||
|
|
]);
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want to allow the field to be empty, first in the database table to face the field set to `NULL`, and then
|
||
|
|
|
||
|
|
```php
|
||
|
|
$form->text('title')->rules('nullable');
|
||
|
|
```
|
||
|
|
|
||
|
|
