User avatar-ACF fields

我正在运行wp multisite，并在我的功能中为我的本地化身使用ACF自定义字段（用户编辑）。我添加的php：

add_action(\'get_avatar\', \'tsm_acf_profile_avatar\', 10, 3);
function tsm_acf_profile_avatar( $avatar, $id_or_email, $size, $default, $alt ) {

$user = \'\';

// Get user by id or email
if ( is_numeric( $id_or_email ) ) {

    $id   = (int) $id_or_email;
    $user = get_user_by( \'id\' , $id );


} elseif ( is_object( $id_or_email ) ) {

    if ( ! empty( $id_or_email->user_id ) ) {
        $id   = (int) $id_or_email->user_id;
        $user = get_user_by( \'id\' , $id );
    }

} else {
    $user = get_user_by( \'email\', $id_or_email );
}

if ( ! $user ) {
    return $avatar;
}

// Get the user id
$user_id = $user->ID;

// Get the file id
$image_id = get_user_meta($user_id, \'avatar\', true); // CHANGE TO YOUR FIELD NAME

// Bail if we don\'t have a local avatar
if ( ! $image_id ) {
    return $avatar;
}

// 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];
// Get the img markup
$avatar = \'<img alt="\' . $alt . \'" src="\' . $avatar_url . \'" class="avatar avatar-\' . $size . \'" height="\' . $size . \'" width="\' . $size . \'"/>\';

// Return our new avatar
return $avatar;
 }

这在主博客（博客1）上效果很好，但问题是，当我在子网站（博客2）上添加用户时，我的头像字段在博客2中是空的，而且在这之后，如果我在博客2上上传头像，那么博客1上的同一个用户会得到一些随机用户的随机图像。

我不知道为什么会发生这种情况，欢迎提供任何帮助。

非常感谢。

<?php // Define user ID // Replace NULL with ID of user to be queried $user_id = NULL; // Example: Get ID of current user // $user_id = get_current_user_id(); // Define prefixed user ID $user_acf_prefix = \'user_\'; $user_id_prefixed = $user_acf_prefix . $user_id; ?>

add_action(\'get_avatar\', \'tsm_acf_profile_avatar\', 10, 3); function tsm_acf_profile_avatar( $avatar, $id_or_email, $size, $default, $alt ) { $user = \'\'; // Get user by id or email if ( is_numeric( $id_or_email ) ) { $id = (int) $id_or_email; $user = get_user_by( \'id\' , $id ); } elseif ( is_object( $id_or_email ) ) { if ( ! empty( $id_or_email->user_id ) ) { $id = (int) $id_or_email->user_id; $user = get_user_by( \'id\' , $id ); } } else { $user = get_user_by( \'email\', $id_or_email ); } if ( ! $user ) { return $avatar; } // Get the user id $user_id = $user->ID; // Get the file id $image_id = get_user_meta($user_id, \'avatar\', true); // CHANGE TO YOUR FIELD NAME // Bail if we don\'t have a local avatar if ( ! $image_id ) { return $avatar; } // 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]; // Get the img markup $avatar = \'<img alt="\' . $alt . \'" src="\' . $avatar_url . \'" class="avatar avatar-\' . $size . \'" height="\' . $size . \'" width="\' . $size . \'"/>\'; // Return our new avatar return $avatar; }
