我有来自Wordpress的以下PHP模板。我正在尝试使用JQuery Validation插件为表单字段添加一些验证。这些字段标题为“newsletter_first_name”，“newsletter_last_name”和“newsletter_email”，我希望用户只有在填写完所有字段后才能提交表单，并且用户已承诺捐赠致慈善机构。但是，在使用Jquery Validation插件编辑表单时，表单仍然提交并且验证不起作用。
这与PHP函数内部的表单有什么关系吗？有没有人有任何关于如何解决这个问题的提示？注意 - 这不是Contact Form 7构建的表单。
我的代码如下：
function sell_media_free_downloads_cart_form() {
$value = get_post_meta( $_POST['product_id'], 'sell_media_free_downloads', true );
if ( empty( $value ) )
return;
?>
<form method="post" name="donate" id="donate">
<style type="text/css">.total-container, .button-container, .sell-media-form fieldset { display: none; }</style>
<div class="sell_media_free_downloads_cart_form">
<h3><?php _e( "Free Download - Voluntary Charity Contribution", "sell_media" ); ?></h3>
<p class="medium"><?php _e( "All of our photos are free to download, subject to a voluntary donation to charity.", "sell_media" ); ?></p>
<!--<form id="newsletter_form" name="newsletter_form" action="javascript://" method="POST">-->
<div id="free_download_form">
