Customizing data before filling the form
You may wish to modify the data from a record before it is filled into the form. To do this, you may define amutateFormDataBeforeFill() method on the Edit page class to modify the $data array, and return the modified version before it is filled into the form:
Customizing data before saving
Sometimes, you may wish to modify form data before it is finally saved to the database. To do this, you may define amutateFormDataBeforeSave() method on the Edit page class, which accepts the $data as an array, and returns it modified:
Customizing the saving process
You can tweak how the record is updated using thehandleRecordUpdate() method on the Edit page class:
Customizing redirects
By default, saving the form will not redirect the user to another page. You may set up a custom redirect when the form is saved by overriding thegetRedirectUrl() method on the Edit page class.
For example, the form can redirect back to the List page of the resource:
Customizing the save notification
When the record is successfully updated, a notification is dispatched to the user, which indicates the success of their action. To customize the title of this notification, define agetSavedNotificationTitle() method on the edit page class:
getSavedNotification() method on the edit page class:
null from the getSavedNotification() method on the edit page class:
Lifecycle hooks
Hooks may be used to execute code at various points within a page’s lifecycle, like before a form is saved. To set up a hook, create a protected method on the Edit page class with the name of the hook:beforeSave() method will be called before the data in the form is saved to the database.
There are several available hooks for the Edit pages:
Saving a part of the form independently
You may want to allow the user to save a part of the form independently of the rest of the form. One way to do this is with a section action in the header or footer. From theaction() method, you can call saveFormComponentOnly(), passing in the Section component that you want to save:
$operation helper is available, to ensure that the action is only visible when the form is being edited.
Halting the saving process
At any time, you may call$this->halt() from inside a lifecycle hook or mutation method, which will halt the entire saving process:
Authorization
For authorization, Filament will observe any model policies that are registered in your app. Users may access the Edit page if theupdate() method of the model policy returns true.
They also have the ability to delete the record if the delete() method of the policy returns true.
Custom actions
“Actions” are buttons that are displayed on pages, which allow the user to run a Livewire method on the page or visit a URL. On resource pages, actions are usually in 2 places: in the top right of the page, and below the form. For example, you may add a new button action next to “Delete” on the Edit page:Adding a save action button to the header
The “Save” button can be added to the header of the page by overriding thegetHeaderActions() method and using getSaveFormAction(). You need to pass formId() to the action, to specify that the action should submit the form with the ID of form, which is the <form> ID used in the view of the page:
getFormActions() method to return an empty array:
Creating another Edit page
One Edit page may not be enough space to allow users to navigate many form fields. You can create as many Edit pages for a resource as you want. This is especially useful if you are using resource sub-navigation, as you are then easily able to switch between the different Edit pages. To create an Edit page, you should use themake:filament-page command:
getPages() method:
form() for this page, which can contain other fields that are not present on the main Edit page:
Adding edit pages to resource sub-navigation
If you’re using resource sub-navigation, you can register this page as normal ingetRecordSubNavigation() of the resource:
Custom page content
Each page in Filament has its own schema, which defines the overall structure and content. You can override the schema for the page by defining acontent() method on it. The content() method for the Edit page contains the following components by default:
components() array, you can insert any schema component. You can reorder the components by changing the order of the array or remove any of the components that are not needed.
Using a custom Blade view
For further customization opportunities, you can override the static$view property on the page class to a custom view in your app:
resources/views/filament/resources/users/pages/edit-user.blade.php:
