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 = $originalAttributes['username'];
});
Be careful, prior to Laravel 7
getOriginal
ignores attribute type casting.
In Laravel 4.0 and 4.1, you can check with isDirty() method:
User::updating(function($user)
{
if ($user->isDirty('username')){
doSomething();
}
});
