What is Accessor in Laravel?
As we know laravel accessor is very userful feature. It is used for creating the virtual attribute on the object which you want to access it as database column name.
So for example if you want to show full name and in your database table (users) has first_name and last_name columns, you can write:
public function getFullNameAttribute()
{
return $this->first_name . " " . $this->last_name;
}Then you can call $user->full_name and it will return the first and last name collectively. Naming convention for accessor is a snake_case attribute, so getFullNameAttribute function would be accessible through $user->user_name.
prefix must be added as get and suffix would be Attribute
