在WordPress中，你可以使用 add_action 函数添加一个钩子函数。钩子函数是在特定事件发生时自动触发的函数。
add_action 函数的第一个参数是钩子名称，第二个参数是要执行的函数名，第三个参数是函数的优先级（可选）。
例如，添加一个在文章保存后执行的钩子函数的代码如下：
function my_save_post_function( $post_ID, $post ) {
// 执行你的代码
}
add_action( 'save_post', 'my_save_post_function', 10, 2 );
这里， save_post 是钩子名称， my_save_post_function 是要执行的函数名，10是函数的优先级，2是传递给钩子函数的参数数量。
wp_reset_query() 函数用于重置WordPress的查询。在自定义查询或修改查询参数之后，你可能需要使用这个函数来重置到默认的查询。例如：
// 自定义查询
$args = array(
'post_type' => 'product',
'posts_per_page' => 10,
);
$custom_query = new WP_Query($args);
// 重置查询
wp_reset_query();
创建自定义的WordPress插件需要以下步骤：
使用 get_post 和 get_page 获取单个文章或页面的详细信息：
// 获取文章或页面的ID $post_id = get_the_ID(); // 获取文章或页面的详细信息 $post = get_post($post_id); // 获取文章或页面的标题 $title = $post->post_title; // 获取文章或页面的内容 $content = $post->post_content;
wp_enqueue_script 和 wp_enqueue_style 函数的使用：
wp_enqueue_script() ：此函数位于wp-includes/script-loader.php文件中。它会将JavaScript文件添加到WordPress网站的页脚中。您可以在主题的functions.php文件中调用此函数，以添加自定义的JavaScript文件。wp_enqueue_style() ：此函数位于wp-includes/script-loader.php文件中。它会将CSS文件添加到WordPress网站的部分中。您可以在主题的functions.php文件中调用此函数，以添加自定义的CSS文件。使用 wp_head 和 wp_footer 在主题中添加自定义内容：
wp_head() ：此函数位于wp-includes/general-template.php文件中。它会在文档的部分中输出内容。您可以在主题的header.php文件中调用此函数，以在部分中添加自定义内容。wp_footer() ：此函数位于wp-includes/general-template.php文件中。它会在文档的部分中输出内容。您可以在主题的footer.php文件中调用此函数，以在部分中添加自定义内容。
