data-request-flash

When included, displays error messages as flash notifications instead of native alert() dialogs. Also enables display of flash messages sent from the server via ajax()->flash().

<form
    data-request="onSuccess"
    data-request-flash>
    <!-- Form Contents -->
</form>

Supported Values

These values control which flash message types are displayed (from ajax()->flash()):

Value	Behavior
(empty)	Shows all standard types: success, error, warning, info
error,success	Shows only specified types (comma-separated)
-error	Shows all except specified types (negation with minus prefix)

Error Severity

Fatal errors (server errors, database failures) always display as alert() dialogs, even with this attribute enabled. Only recoverable errors (validation, business logic) are shown as flash messages.

// Shows as flash message with data-request-flash
return ajax()->error('Please check your input');

// Always shows as alert(), regardless of attributes
return ajax()->fatal('Database connection failed');

Combined with Validation

When used with data-request-validate, validation errors display both inline and as flash messages:

<form
    data-request-validate
    data-request-flash>

To show inline validation only (without flash messages for validation errors), exclude the validate type:

<form
    data-request-validate
    data-request-flash="-validate">
