I want to add a custom message on date_format validation in laravel but conldn't find any thing.How i can add a custom message I have used this

$messages = [ 'postmeta.event_type.required' => 'event type is required', 'postmeta.event_type.date_format' => 'This is not working i want to add a custom message here', ];

    $rules = [
        'postmeta.start_date' => 'required|date_format:Y-m-d',
        'postmeta.end_date' => 'required|date_format:Y-m-d',
        'postmeta.start_time' => 'required|date_format:H:i:s',

In {project}\resources\lang path, you can see different types of languages. for change validation message it just enough find the field intended in validation.php and change the message.

you should change this:

'date_format' => 'The :attribute does not match the format :format.',

UPDATED:

in laravel V9 the lang folder is at the root of the project.
