ACF User Roles Field

ACF User Roles Field is a Wordpress plugin that adds a new ACF field allowing to select user roles.

Note that this plugin doesn't manage content access. It only shows a select field with all user roles as choices.

Installation

• Download the latest version on GitHub.

• Extract the archive and copy the folder (acf-user-roles-field) to the Wordpress plugins folder (/wp-content/plugins/).

• Go to the Wordpress plugins manager on your website (your-website.ext/wp-admin/plugins.php) and enable the plugin ACF User Roles Field. Note that you can enable auto-updates.

Usage

Admin

Go to the ACF administration page (your-website.ext/wp-admin/edit.php?post_type=acf-field-group), add a new field group and choose the field User roles:

Front-end

To display the field value, the shortcode acf_user_roles_field can be used. By default, it'll look at custom fields for the current post where the shortcode is added. For example, the following shortcode:

[acf_user_roles_field name="FIELD_NAME"]

is the same as this one:

[acf_user_roles_field name="FIELD_NAME" type="post"]

To get the field value from another post, use the attribute id:

[acf_user_roles_field name="FIELD_NAME" id="POST_ID"]

If the field is linked to a user, set the type user in the shortcode. By default, it'll look at custom fields for the current user:

[acf_user_roles_field name="FIELD_NAME" type="user"]

To specify a specific user, set the attribute id:

[acf_user_roles_field name="FIELD_NAME" type="user" id="USER_ID"]

By default, user roles are displayed as an HTML list. Example:

<ul>
	<li>Author</li>
	<li>Subscriber</li>
</ul>

To display them as a simple text list, the attribute separator can be set. Example:

[acf_user_roles_field name="FIELD_NAME" separator=", "]

User roles will be displayed as follows:

Author, Subscriber

Hooks for developers

The following filter hook is available:

• acf_user_roles_field_html: filter allowing to manipulate the HTML code before it's displayed

For example, to display the user roles with an ordered list, use the filter in your functions.php theme file as follows:

function user_roles_in_ordered_list($html, $user_roles, $atts) {
	return str_replace(
		['<ul ', '</ul>'],
		['<ol ', '</ol>'],
		$html
	);
}
add_filter('acf_user_roles_field_html', 'user_roles_in_ordered_list', 10, 3);

Here's another way:

function user_roles_in_ordered_list($html, $user_roles, $atts) {
	$custom_html = '<ol>';
	
	foreach ($user_roles as $user_role) {
		$custom_html .= '<li>' . $user_role . '</li>';
	}
	
	$custom_html .= '</ol>';
	
	return $custom_html;
}
add_filter('acf_user_roles_field_html', 'user_roles_in_ordered_list', 10, 3);
