How to limit Meta Slider to editor only (not authors)

Hi there,

One method would be to add something like this to your theme’s functions.php file:

function check_user_role($roles,$user_id=NULL) {
	// Get user by ID, else get current user
	if ($user_id)
		$user = get_userdata($user_id);
	else
		$user = wp_get_current_user();

	// No user found, return
	if (empty($user))
		return FALSE;

	// Append administrator to roles, if necessary
	if (!in_array('administrator',$roles))
		$roles[] = 'administrator';

	// Loop through user roles
	foreach ($user->roles as $role) {
		// Does user have role
		if (in_array($role,$roles)) {
			return TRUE;
		}
	}

	// User not in roles
	return FALSE;
}

// Define roles to check
$roles = array('editor','administrator',);

// Check roles
$in_role = check_user_role($roles);

// Do something based on role
if ($in_role) {
  // User in role, do something
} else {
  // User not in role do something else
  remove_all_filters( 'media_buttons_context' );
}

This code to check the role of the logged-in user is here:
https://wpbandit.com/code/check-a-users-role-in-wordpress/

The code that we’ve added if the user is not an editor or an administrator is:
remove_all_filters( ‘media_buttons_context’ );

Please note that this applies to all custom buttons, so if you have other plugins that add buttons in the same place, those will be removed too. The default ‘Add Media’ button will remain.

Thanks,

Thanks a lot for your help Dave.
