Entfernen der Gravatar.com-Unterstützung für WordPress und Simple Local Avatars

Gegenwärtig verwende ich Simple Local Avatars in mehreren meiner Blogs, damit Benutzer ihren eigenen benutzerdefinierten Avatar hochladen können.

Soweit ich weiß, verwendet Simple Local Avatars get_avatar, um zu überprüfen, ob ein benutzerdefinierter Avatar ausgewählt ist. Andernfalls wird standardmäßig Gravatar.com verwendet.

Wäre es möglich, das Gravatar.com-Bit irgendwie zu deaktivieren, Gravatar.com vollständig zu deaktivieren und nur einige lokal gehostete Bilder zurückzugeben, wenn kein benutzerdefinierter Avatar ausgewählt ist?

Ich hoffe, es wäre in Ordnung, dies hier zu posten, aber dies wäre die Simple Local Avatars-Datei

Wenn Sie eine superleichte Lösung wünschen und sich nicht mit ein wenig Code auseinandersetzen möchten, geben Sie dies in Ihren functions.php ein.

function __default_local_avatar()
{
    // this assumes default_avatar.png is in wp-content/themes/active-theme/images
    return get_bloginfo('template_directory') . '/images/default_avatar.png';
}
add_filter( 'pre_option_avatar_default', '__default_local_avatar' );

Alternativ, wenn Sie ein bisschen mehr Saft wollen, mit der Möglichkeit, alles im Admin zu verwalten, check out Add New Default Avatar .

UPDATE: Ich habe ein schnelles Plugin geschrieben, das neben Simple Local Avatars verwendet werden kann.

Die Beschreibung des Plugins sollte selbsterklärend sein, aber im Wesentlichen ist der Standardavatar http://wordpress-theme-path/images/default_avatar.png, der in functions.php Ihres Themas gefiltert werden kann, falls er an anderer Stelle vorhanden ist.

function __my_theme_default_avatar( $url )
{
    return 'http://somewhere/else.jpg';
}
add_filter( 'local_default_avatar', '__my_theme_default_avatar' );

Ich habe erfolgreich alle gravitar.com-Avatare durch mein eigenes, lokal gehostetes Avatar-Bild ersetzt, indem ich Folgendes zu der function.php-Datei meines Themas hinzugefügt habe:

define('DEFAULT_AVATAR_URL', get_template_directory_uri() . '/images/user.png');

function no_gravatars( $avatar ) {
    return preg_replace( "/http.*?gravatar\.com[^\']*/", DEFAULT_AVATAR_URL, $avatar );
}
add_filter( 'get_avatar', 'no_gravatars' );

Dies setzt voraus, dass Sie einen lokalen Standard-Avatar namens user.png im Unterverzeichnis images Ihres Themas haben.

Vergewissern Sie sich, dass im discussion settings Admin-Bereich "Show Avatars" (Avatare anzeigen) aktiviert ist.

Ich habe dies nicht mit Simple Local Avatars getestet, aber es funktioniert hervorragend mit Basic User Avatars (das ist eine leichte Gabelung von Simple Local Avatars).

TIP: Wenn Sie Ihren eigenen Standard-Avatar entwerfen, empfehle ich, ihn auf 300 x 300 Pixel einzustellen, damit er auf "Retina" -Bildschirmen gut aussieht, wenn WP ihn mit "150 x 150" anzeigt. . Dann können Sie die Dateigröße des Bildes erheblich reduzieren, indem Sie es unter tinyPNG.com komprimieren.

Avatare vollständig entfernen. Fügen Sie diesen Code in die Datei functions.php Ihres Themas ein.

add_action( 'init', 'qmas_remove_avatars' );
if (!function_exists('qmas_remove_avatars')) {
    function qmas_remove_avatars() {
        add_filter( 'bp_core_fetch_avatar', function () { return ''; } );
        add_filter( 'get_avatar', function () { return ''; } );
        add_filter( 'bp_get_signup_avatar', function () { return ''; } );
    }
}
