Frontend Simple Local Avatar hochladen

Ich verwende Einfache lokale Avatare zum Hochladen benutzerdefinierter Benutzeravatare.

Wie kann ich mit der Avatar-Upload-Funktion eine Frontend-Seite erstellen?

Nachfolgend finden Sie den Code des Simple Local Avatars-Plugins:

    <?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))

Ich habe viele Varianten ausprobiert, aber alle sind gescheitert.

Könnten Sie bitte einen Hinweis geben, welche Codeteile ich in meine benutzerdefinierte Frontend-Vorlagendatei kopieren soll?

Vielen Dank.

Sergey, benutze dies an der Stelle, an der du das Formular platzieren willst, um den Avatar zu bearbeiten:

<?php
$myAv = new simple_local_avatars();
$myAv->edit_user_profile($profileuser); 
?>

hinzufügen

do_action('show_user_profile');
do_action('edit_user_profile');

zu Ihrer benutzerdefinierten Frontend-Vorlage

und beim Speichern hinzufügen:

do_action('personal_options_update');
do_action('edit_user_profile_update');

Wir benötigen zweite Parameter, die an die Aktionen übergeben werden:

  1. action edit_user_profile benötigt ein Wordpress-Benutzerobjekt (wir nehmen es aus der WP_User-Klasse)
  2. action edit_user_profile_update benötigt die Benutzer-ID

Die erste Aktion rendert das Upload-Feld und den aktuellen Avatar und die zweite führt den Upload selbst durch. Deshalb müssen wir es nach dem Klicken auf die Schaltfläche auslösen. Wir warten auf die Schaltfläche am Anfang des Codes. Nach dem Absenden wird die Seite aktualisiert und der Avatar aktualisiert (andernfalls wird er als defektes Bild angezeigt).

Hier ist mein Setup:

<?php if(isset($_POST['user_avatar_edit_submit']))
      {
           do_action('edit_user_profile_update', bbp_get_displayed_user_id());
      }
?>
<form id="your-profile" action="<?php bbp_user_profile_edit_url( bbp_get_displayed_user_id() ); ?>" method="post">
<?php 
    $this_user = new WP_User(bbp_get_displayed_user_id());
    do_action('edit_user_profile', $this_user);
?>

    <input type="submit" name="user_avatar_edit_submit" value="OK"/>
</form>

<?php get_header();
global $user_ID;
if ($user_ID) {
$user_info = get_userdata($user_ID);
$id = $user_info->ID;
}
 ?>
<?php if(isset($_POST['user_avatar_edit_submit']))
      {
           do_action('edit_user_profile_update', $id);
      }
?>

<form id="your-profile" action="" method="post">
    <?php
    $myAv = new simple_local_avatars();
    $myAv->edit_user_profile($user_info);
    ?>
    <input type="submit" name="user_avatar_edit_submit" value="OK"/>
</form>



<?php get_footer(); ?>
