Special CMB2 Field that allows users to define an autocomplete text field for users
$cmb2->add_field( array(
'name' => 'Author',,
'id' => 'author',
'desc' => 'Type the name of the author and select from the options',
'type' => 'user_select_text'
'options' => array(
'user_roles' => array( 'role1', 'role2' ), // Specify which roles to query for.
),
) );The value returned is an array with the users id and name, eg:
array(
'id' => 1
'name' => 'Joe Blogs'
)This will be serialised if saved directly into the database.
If you wish to store the users ID only, you can use escape_cb and sanitization_cb to transform
the data.
/**
* Takes the id from the database and returns an array for user_select_text
* @param int $value
* @return array('name' => string, 'id' => int)
*/
function id_to_user_select_text($value) {
$user = get_user_by('id', (int)$value);
return array(
'name' => $user->display_name,
'id' => $user->ID,
);
}
/**
* Takes the array from user_select_text and returns the id for the database
* @param array('name' => string, 'id' => int) $value
* @return int
*/
function user_select_text_to_id($value) {
return $value['id'];
}
$cmb2->add_field( array(
// ...snip...
'escape_cb' => 'user_select_text_to_id',
'sanitization_cb' => 'id_to_user_select_text',
) );
