Caricamento del frontend semplice dell'avatar locale
Domanda
sto usando Semplici avatar locali Per caricare avatar utente personalizzati.
Come posso creare una pagina frontend con la funzione di caricamento Avatar?
Di seguito trovi il codice dal plug -in semplice degli avatar locali:
<?php
/**
* add field to user profiles
*/
class simple_local_avatars {
function simple_local_avatars() {
add_filter('get_avatar', array($this, 'get_avatar'), 10, 5);
add_action('admin_init', array($this, 'admin_init'));
add_action('show_user_profile', array($this, 'edit_user_profile'));
add_action('edit_user_profile', array($this, 'edit_user_profile'));
add_action('personal_options_update', array($this, 'edit_user_profile_update'));
add_action('edit_user_profile_update', array($this, 'edit_user_profile_update'));
add_filter('avatar_defaults', array($this, 'avatar_defaults'));
}
function get_avatar($avatar = '', $id_or_email, $size = '80', $default = '', $alt = false) {
if (is_numeric($id_or_email))
$user_id = (int) $id_or_email;
elseif (is_string($id_or_email)) {
if ($user = get_user_by_email($id_or_email))
$user_id = $user->ID;
} elseif (is_object($id_or_email) && !empty($id_or_email->user_id))
$user_id = (int) $id_or_email->user_id;
if (!empty($user_id))

if (!isset($local_avatars) || empty($local_avatars) || !isset($local_avatars['full'])) {

remove_filter('get_avatar', 'get_simple_local_avatar');
$avatar = get_avatar($id_or_email, $size, $default);
add_filter('get_avatar', 'get_simple_local_avatar', 10, 5);
return $avatar;
}
if (!is_numeric($size))

Ho provato molte varianti ma tutte fallite.
Potresti dare un suggerimento, quali pezzi di codice copierò nel mio file modello di frontend personalizzato?
Grazie mille.
