根据上面的评论，您不能直接使用此功能。因此，我们需要按照下面给出的步骤添加此功能。

在评论表单中添加性别字段

// Add the actions to show gender field on comment form
add_action( \'comment_form_logged_in_after\', \'wti_additional_comment_field\' );
add_action( \'comment_form_after_fields\', \'wti_additional_comment_field\' );

function wti_additional_comment_field() {
    echo \'<p class="comment-form-gender">\'.
            \'<label for="gender_male">\' . __( \'Gender\' ) . \'</label>\'.
            \'<input id="gender_male" name="gender" type="radio" value="male" checked="checked" /> \' . __( \'Male\' ) .
            \'<input id="gender_female" name="gender" type="radio" value="female" />\' . __( \'Female\' ) .
        \'</p>\';
}

// Add the action to save the gender in comment
add_action( \'comment_post\', \'wti_save_comment_meta_data\' );

function wti_save_comment_meta_data( $comment_id ) {
    $gender = wp_filter_nohtml_kses( $_POST[\'gender\'] );
    add_comment_meta( $comment_id, \'gender\', $gender );
}

// Add the filter to have custom avatar
add_filter(\'get_avatar\', \'wti_custom_avatar\', 10, 5);

function wti_custom_avatar($avatar, $id_or_email, $size, $default, $alt) {
    global $comment;

    if ( is_object ( $comment ) && !empty ( $comment ) ) {
        // Remove to avoid recursion
        remove_filter( \'get_avatar\', \'wti_custom_avatar\' );

        // Get the comment id and gender for that comment
        $comment_id = get_comment_ID();
        $gender = get_comment_meta( $comment_id, \'gender\', true );

        // Assign the image url as per gender
        if ( $gender == \'female\' ) {
            $default = \'default_female_avatar_url\';
        } else {
            $default = \'default_male_avatar_url\';
        }

        // Get the avatar with default url
        $avatar = get_avatar( $comment, $size, $default );

        // Add the filter again
        add_filter( \'get_avatar\', \'wti_custom_avatar\', 10, 5 );
    }

    return $avatar;
}

安装BuddyPress，然后创建xProfile字段，如名称、位置、，gender 等等然后简单地写一个条件语句来查找成员的性别。i、 e伪代码：

if gender == male then do this
