这可以通过存储插件的版本并检查该版本是否存在来实现，这意味着插件已安装，如果不存在，则可以设置默认选项“仅一次”。

检查插件是否已安装，如果未安装，则设置默认选项并存储插件版本，以避免在每次加载页面时重置选项

// check for new installation and setup default options
add_action( \'init\', \'check_plugin_version\' );
function check_plugin_version() {

    // this will run your default option setup if the version does not exist
    if ( ! defined( \'IFRAME_REQUEST\' ) && get_option( \'my_plugin_version\' ) == null ) {
        setup_options();
        update_option( \'my_plugin_version\', \'1.0.0\' );
    }
}
设置默认选项
// setup default options
function setup_options() {

    // here you can save your default options
    // the first time your plugin will run

    update_option( \'myoption_id1\', \'...\' );
    update_option( \'myoption_id2\', \'...\' );
    //etc

}

最好是在激活挂钩上设置默认值，如果用户在选项页面上删除此值，则添加回退。

register_activation_hook(   __FILE__, array($this, \'_plugin_activation\') );

public function _plugin_activation(){
    if(!get_option(\'price_list_options_option_name\')) {
    //not present, so add new options
    $options = array(
        \'price_list_section_title_0\'=> \'default title\',
        \'price_list_section_subtitle_1\'=> \'default subtitle\',
        etc...

    );

    add_option(\'price_list_options_option_name\', $options);
  }
}
您可以对“清理”自定义函数和\\u plugin\\u激活选项数组使用相同的选项数组（和默认值），以轻松获得相同的默认值。i、 e：在您的\\uu构造（）中，添加，$this->array\\u of\\u default\\u value=array（\'price\\u list\\u section\\u title\\u 0\'=>\'default title\'，\'price\\u list\\u section\\u subtitle\\u 1\'=>\'default subtitle\'，等等）；

从选项页保存选项值时，请选中$\\u POST name。

if(isset($_POST[\'price_list_section_title_0\')== \'\'){
    $default_value = $this->array_of_default_value[\'price_list_section_title_0\'];
    update_option(\'price_list_options_option_name\', \'price_list_section_title_0\', $default_value);
}
