好的，这是允许用户添加电话号码的代码。在函数中粘贴此完整代码。php文件。这将在用户配置文件中为“电话号码”添加新字段，并在WordPress admin中为Phone添加一列用户表。

function new_contact_methods( $contactmethods ) {
    $contactmethods[\'phone\'] = \'Phone Number\';
    return $contactmethods;
}
add_filter( \'user_contactmethods\', \'new_contact_methods\', 10, 1 );


function new_modify_user_table( $column ) {
    $column[\'phone\'] = \'Phone\';
    return $column;
}
add_filter( \'manage_users_columns\', \'new_modify_user_table\' );

function new_modify_user_table_row( $val, $column_name, $user_id ) {
    switch ($column_name) {
        case \'phone\' :
            return get_the_author_meta( \'phone\', $user_id );
        default:
    }
    return $val;
}
add_filter( \'manage_users_custom_column\', \'new_modify_user_table_row\', 10, 3 );

EDIT

function new_modify_user_table( $column ) {
    $column[\'phone\'] = \'Phone\';
    $column[\'xyz\'] = \'XYZ\';
    return $column;
}
add_filter( \'manage_users_columns\', \'new_modify_user_table\' );

function new_modify_user_table_row( $val, $column_name, $user_id ) {
    switch ($column_name) {
        case \'phone\' :
            return get_the_author_meta( \'phone\', $user_id );
        case \'xyz\' :
            return \'\';
        default:
    }
    return $val;
}
add_filter( \'manage_users_custom_column\', \'new_modify_user_table_row\', 10, 3 );
