After_Setup_Theme、全局变量和主题定制器

我使用的是在函数中定义的全局变量after_setup_theme. 此变量未在主题自定义程序中获取更新更改。

Let me explain this with an example:

add_action( \'customize_register\', "example_customizer_register");
function example_customizer_register($wp_customize) {

        $wp_customize->add_setting( \'example_settings[example-variable]\', array(
            \'type\'      => \'option\',
            \'default\'   => false,
            \'sanitize_callback\' => \'esc_attr\'
        ) );
        $wp_customize->add_control( \'example_settings[example-variable]\', array(
            \'label\'    => \'Example Setting\',
            \'type\' => \'checkbox\',
            \'section\'  => \'title_tagline\',
        ) );    
}

add_action("after_setup_theme", "example_after_setup_theme");
function example_after_setup_theme(){
    global $example_settings;
    $example_settings = get_option( "example_settings", array());
}


add_action("wp_head", "example_wp_head");
function example_wp_head(){
    global $example_settings;
    if (isset($example_settings["example-variable"]) && true == $example_settings["example-variable"]) {
        echo "Example Setting";
    }   
}

此代码正在主题自定义程序的站点标识部分添加一个示例设置，但该设置不起作用。如果我改变；

add_action("after_setup_theme", "example_after_setup_theme");

至

add_action("wp", "example_after_setup_theme");

它正在工作。但我需要它after_setup_theme. 有什么解决方案吗？

add_action("after_setup_theme", "example_after_setup_theme"); function example_after_setup_theme(){ global $example_settings; $option_key = "example_settings"; $example_settings = get_option( $option_key, array() ); // Check if wp_customize was posted if( isset( $_POST[\'wp_customize\'] ) && $_POST[\'wp_customize\'] == "on" && !empty( $_POST[\'customized\'] ) ){ // All the variables we need to look for $variables_to_find = array( \'example-variable\' ); // Get the customized data $customized = json_decode( stripslashes( $_POST[\'customized\'] ), true ); // Make sure it\'s a proper array if( !empty( $customized ) && is_array( $customized ) ){ // Lopp the customized items foreach ($variables_to_find as $sub_key) { // The key in the settings array $key = "{$option_key}[{$sub_key}]"; // If a different value was posted if( array_key_exists( $key, $customized) ){ // Replace it in the current object with the one submitted $example_settings[ $sub_key ] = $customized[ $key ]; } } } } }

RESTORE_CURRENT_BLOG()与MULTIME SWITCH_TO_BLOG()，然后删除$GLOBALS[‘_wp_Switched_Stack’]

与相关this answer, 哪些国家每次switch_to_blog() 你need 调用restore_current_blog() 否则，WP会认为它处于“切换”模式，并可能返回不正确的数据。我已经做了一些测试，可以确认这是一个问题。（它还回答了我在工作中遇到的一个关于文件上传URL的问题，对此我竖起大拇指。）在我的测试（详情如下）中，我发现有两种方法可以继续：始终配对switch_to_blog() 具有restore_current_blog()</使用switch_to_blog(),
