好的......我一直在看这件事，我不得不承认失败。
我正在拼凑一个WordPress主题的选项页面，我正在获取
“警告：call_user_func_array（）[function.call-user-func-array]：第一个参数应该是一个有效的回调函数，在/ home / bahia001 / public_html / test / wp-includes /中给出'flaunt_one_theme_options'第405行上的plugin.php“错误。
我知道这可能是由于我曾经将这些代码片段放在一起的错误命名法，但我需要一些指导。我是PHP的新手。
这是我的代码：
<?php
//Theme Options

wp_enqueue_script('media-upload');

add_action('admin_print_scripts', 'my_admin_scripts');
add_action('admin_print_styles', 'my_admin_styles');
}
add_action('admin_menu', 'flaunt_one_create_menu');
function flaunt_one_create_menu() {
add_menu_page('Flaunt One Options', 'Flaunt One Options', 'administrator','folio-themes-setup', 'flaunt_one_theme_options',get_bloginfo('stylesheet_directory')."/images/flaunt16.png",63);
add_action( 'admin_init', 'register_mysettings' );
}

答案 0 :(得分：2)
看起来错误正在发生，因为当您在代码末尾插入 flaunt_one_options_validate 函数时，该函数无法通过 $ input <接收您要发送的内容/ strong>变量。
function flaunt_one_options_validate( $input )
在页面上，我必须声明输入变量并具有一些值。这需要在调用函数之前以正确的格式（强或数字等）可读。
首先尝试使用静态值测试函数，以便您知道该函数正在运行。然后尝试使变量动态化。
希望这有帮助，一旦你完成了这个更新这篇文章。
