Function and usage of remove_role() in wordpress


Answers ( 1 )


    The remove_role() function in WordPress is a straightforward yet powerful tool used to manage user roles within a WordPress site. Here's a detailed explanation of its function and usage:


    • Purpose: The primary function of remove_role() is to delete a specified user role from the WordPress site.
    • Operation: When this function is called, it removes the role along with all associated capabilities from the WordPress installation. It's important to note that this action is irreversible; once a role is removed, it cannot be reinstated with the same function. You would need to recreate the role and its capabilities if needed again.


    • $role (string, required): This parameter specifies the name of the role you want to remove. The role name should be provided as a string. For instance, roles like 'editor', 'author', 'contributor', etc., can be targeted for removal.

    Sample Usage:

    Here's an example of how remove_role() can be used in a WordPress theme or plugin:

    if ( function_exists( 'remove_role' ) ) {
        remove_role( 'custom_role' );

    In this snippet:

    1. Check for Function Existence: First, it checks if the remove_role() function exists. This is a good practice to avoid errors in cases where the WordPress environment might not have this function defined (though it's rare for standard installations).
    2. Remove Role: The function remove_role('custom_role') is called to remove a role named 'custom_role'. Replace 'custom_role' with the actual name of the role you wish to remove.

    Important Notes:

    • Backup: Always back up your WordPress site before performing operations like removing roles, as these changes affect user access and capabilities.
    • Reusability: If you need the role again in the future, you'll have to recreate it manually.
    • Usage Scope: This function is typically used by developers in custom themes or plugins to modify the user role structure of a WordPress site for specific needs.

    By using remove_role(), WordPress developers can customize the user role and capabilities setup to suit the specific needs of their website or application.
