我使用add_theme_page() 在我的孩子主题中functions.php 实现了如下内容。。。

// other functions located here that create a custom options page in the Dashboard.
// THIS IS NOT A FILE PATH ISSUE ->  THE CUSTOM PAGE IS CREATED IN BOTH CASES.

function my_menu() {
    ...
    if ( \'save\' == $_REQUEST[\'action\'] ) {
        echo \'<meta http-equiv="refresh" content="0;url=themes.php?page=functions.php&saved=true">\';
        die;
    }
    add_theme_page(...)
}

add_action(\'admin_menu\', \'my_menu\');

注意：如果您正在运行中，您没有足够的权限访问此页面。«中的消息wp_die() 屏幕，那么你已经上钩太早了。你应该用的钩子是admin_menu.

这正是我在保存选项后遇到的错误。然而，我已经按照建议使用了正确的挂钩。

仅当我将函数移动到新文件并使用require_once 在内部funtions.php. 我按照this answer.

require_once(\'includes/functions-theme-options.php\');

当代码位于functions.php, 它工作得很好。

当代码移动到外部文件并引用时require_once(), 它会中断（根据上面引用的文档保存时出现的错误消息）。

显然，目前，我将其控制在function.php, 但也许有人能解释为什么我移动它时它会断裂。

EDIT

在里面functions.php 文件：

<?php

require_once(\'includes/functions-test.php\');

<?php

$themename = wp_get_theme();

function mytheme_admin() {

    global $themename;

    if ( $_REQUEST[\'saved\'] ) echo \'<div id="message" class="updated fade"><p><strong>\'.$themename.\' settings saved.</strong></p></div>\';

    ?>

    <div class="wrap">
        <h2><?php echo $themename; ?> Options</h2>
        <div style="border-bottom: 1px dotted #000; padding-bottom: 10px; margin: 10px;">Options specfic to this theme.</div>
        <form method="post">
            <p class="submit">
                <input name="save" type="submit" class="button button-primary" value="Save Options" />    
                <input type="hidden" name="action" value="save" />
            </p>
        </form>
    </div>

<?php               
}


function wp_initialize_the_theme_load() {
    if (!function_exists("wp_initialize_the_theme")) { 
        wp_initialize_the_theme_message();
        die;
    }
}

add_action(\'admin_menu\', \'mytheme_add_admin\');
