Where to put/how to handle enums in Laravel?

Answer 1

You have several options for handling enums. Before we look at a few though, I would first strongly encourage you not to use the DB enum column type.

Database enums are problematic for a number of reasons. I suggest reading this article for example:

http://komlenic.com/244/8-reasons-why-mysqls-enum-data-type-is-evil/

So with that let's look at a few other options.

Using Laravel config

Since you're using Laravel, one very simple option is to stick an array of options in a config file.

Say you create a new file config/enums.php with the following:

return [
    'phone_types' => [
        'CELL' => "Cellular",
        'HOME' => "Home",
        'WORK' => "Work",
    ]
];

You can now access config('enums.phone_types') anywhere in your code, including your Blade template.

Using a PHP package

@Banford's answer shows how to do basic enum-type behavior with class constants. If you like that approach, I recommend looking at this article and package which builds on this concept to provide strongly type enums:

https://stitcher.io/blog/php-enums

https://github.com/spatie/enum

You would create a class like this:

/**
 * @method static self cell()
 * @method static self home()
 * @method static self work()
 */
class PhoneTypes extends Enum
{
}

And now you can call PhoneTypes::home() in your app. Check out the documentation for that package to see how you can create a map of values, if you want.

Using DB relationships

If you really want to manage your options in the database, I'd create a separate phone_types database table and create a relationship with your customers table. This is still a much better option than using enum column type.
