Advanced Custom Fields is the most popular custom fields plugin. It adds a slick interface to the backend which enables you to add different meta box types for custom field data entry. Then you can use code in your theme to output or return the value for your custom fields.
The only problem is, the code ACF provides only works when the ACF plugin is active.
If the plugin is deactivated or you decide you no longer want to use it, the code ACF provides to use in your theme will no longer work and possibly cause fatal or non fatal errors.
