# Manually saving data

### FieldFoo::make('Foo')->custom()

If you want to be in control of how a field is saved add the `custom()` method to the field

```
    Input::make('My custom field', 'foo')
      ->custom()
      ->rule('required'),
```

### FieldFoo::make('Foo')->relation()

The `relation()` method does the same as `custom()`, it is just there for code readability 

```
    Select::make('Parent', 'parent_id')
      ->relation()
      ->rule('required'),
```

## saveFoo() - save the data

If you used the `custom()` or `relation()` method on your field, it will be excluded from the default save method, so **you must save them yourself** via the `saveFoo()` hook.

The method is executed **AFTER field validation** and **AFTER** the **model is created or updated,** meaning that you have access to `$this->model` even if it is a `create` form.

```php
protected function saveFoo($validated_field_value)
{
    //the validate field value is passed to the hook
    $field_value = $validated_field_value;
    
    //or get the field value via the fields name property
    $field_value = $this->foo;
    
    //or via form_data
    $field_value = data_get($form_data, 'foo');
    
    //save the data
    $this->model->foo = $field_value;
}
```

**You do NOT have to prefix with `FormData`**

* Example method name for an array field `form_data.people.name` will become `savePeopleName($validated_value)`
* Example method name for `form_data.some_field_name` will become `saveSomeFieldName($validated_value)`

Example; `form_data.price` 

```php
public function savePrice($validated_value)
{
    $this->model->price = $validated_value;
    $this->model->save();
}
```
