Select a specific value from an image object in a repeater field

I have a images in a repeater field added to the user settings page so a user can have a choice of avatar. Once they make the choice the ID of the chosen image object is added to their user meta.

Is there a way to use that image object id to select that specific images url for display as their avatar?

Hi @eggbeater

I believe you can do it like this:

function example_callback( $avatar, $id_or_email, $size, $default, $alt, $args ) {
    $user_image = get_field('user_image_field_name', 'user_1');
    $gravatar_url = str_replace('&','&',$args['url']);
    $avatar = str_replace($gravatar_url, $user_image['sizes']['thumbnail'] , $avatar);
    return $avatar;
}
add_filter( 'get_avatar', 'example_callback', 20, 6 );

Keep in mind that that code is an example for an image field, not a repeater field. Also, please change the “user_1” parameter. This page should give you more idea about it: http://www.advancedcustomfields.com/resources/how-to-get-values-from-a-user/.

I hope this helps.

I was actually able to solve this with a completely WP method.
Since I had the user’s chosen image ID stored in the user meta I was able to get the URL using that ID

<?
// Get the file id
$image_id = get_user_meta($userid, 'meta_field_key', true); // CHANGE TO YOUR FIELD NAME
// Get the file size
$image_url  = wp_get_attachment_image_src( $image_id, 'thumbnail' ); // Set image size by name
// Get the file url
$avatar_url = $image_url[0];
?>
