Get previous attribute value in Eloquent model event

Question

Is there a way to see the old/previous value of a model's attribute in its saving or updating event?

eg. Is something like the following possible:

User::updating(function($user)
{
    if ($user->username != $user->old->username) doSomething();
});

Ok, I found this quite by chance, as it's not in the documentation at present...

There is a getOriginal() method available which returns an array of the original attribute values:

User::updating(function($user)
{
    if ($user->username != $user->getOriginal('username')) {
        doSomething();
    }

    // If you need multiple attributes you may use:
    // $originalAttributes = $user->getOriginal();
    // $originalUsername = $originalAttributes['username']; 
});

Be careful, prior to Laravel 7 getOriginal ignores attribute type casting.

getOriginal has one parameter which is the name of the field you looking for. – Martin Tonev Oct 22 '18 at 08:23

Do you know if that returns the previous object or it returns the first value ever? – Jacobo Apr 01 '19 at 23:43

be carefult, it ignores the model type casting. – Yevgeniy Afanasyev Jul 16 '19 at 06:54

Do note that ever since Laravel 7.x, this method has been renamed to `getRawOriginal()`. See upgrade guide: https://laravel.com/docs/7.x/upgrade – Robin van Baalen Apr 27 '21 at 03:57

@RobinvanBaalen - I haven't tested it, but the new behaviour of getOriginal since Laravel 7 actually seems *more* desirable for doing these comparisons, as I expect the current attribute value has already had casting applied... – coatesap Sep 15 '21 at 07:02
This is not working btw – Mohammad Zarifiyan Mar 24 '23 at 14:10

In Laravel 4.0 and 4.1, you can check with isDirty() method:

User::updating(function($user)
{
    if ($user->isDirty('username')){
        doSomething();
    }
});

This doesn't get the previous value – Sandy Jul 09 '20 at 12:42
still works like a peach in Laravel 9. Thanks! – Inigo May 22 '23 at 08:13

You could overload the methods, then call the parent method.

and now we can do it right here `class AppServiceProvider extends ServiceProvider` in `boot` method. – Bhargav Nanekalva Oct 23 '16 at 15:22
