Forms Wordpress表格提交

我正在Wordpress中为客户重建一个站点。表单提交以前在静态站点上工作得很好，但在Wordpress中没有完全发挥作用

在我的主题中的后端php文件中，我有：

<?php get_header(); ?>

<?php

$responseModal = "";
$error = "";

if ($_POST) {

    if (!$_POST["firstName"] || !$_POST["lastName"]) {

    $error .= "A first & last name is required.<br>";

    }

if (!$_POST["email"]) {

    $error .= "An email address is required.<br>";

}

if (!$_POST["phone"]) {

    $error .= "A phone number is required.<br>";

}

if (!$_POST["subject"]) {

    $error .= "An event description is required.<br>";

}

if (!$_POST["cateringType"]) {

    $error .= "You did not specify the type of catering for your 
event.<br>";

}

if ($error != "") {

    $error = '<div class="alert alert-danger" role="alert"> . 
<strong>There were error(s) in your form:</strong><br>' . $error . 
'</div>';
    $responseModal = '<script type=\'text/javascript\'>
$(document).ready(function(){
$(\'#errorModal\').modal(\'show\');
}); </script>';

} else {

    $emailTo = "foo@example.com";
    $subject = "New Event Request";
    $body = "Name: " . $_POST['firstName'] . " " . $_POST['lastName'] 
.
        "\nEmail: " . $_POST['email'] .
        "\nPhone: " . $_POST['phone'] .
        "\nDate: " . $_POST['month'] . "/" . $_POST['day'] . "/" . 
$_POST['year'] .
        "\nDescription: " . $_POST['subject'] .
        "\nLocation: " . $_POST['location'] .
        "\nCateringType: " . $_POST['cateringType'];
    $headers = "From: " . $_POST['email'];
    if (mail($emailTo, $subject, $body, $headers)) {

        $responseModal = '<script type=\'text/javascript\'>
$(document).ready(function(){
$(\'#successModal\').modal(\'show\');
}); </script>';

    } else {

        $error = '<div class="alert alert-danger" role="alert"> . 
<strong>You message could not be delivered - please try again later. 
</strong></div>';
        $responseModal = '<script type=\'text/javascript\'>
$(document).ready(function(){
$(\'#errorModal\').modal(\'show\');
}); </script>';

    }
}
}

?>

<?php //get_template_part( 'content', get_post_format() );  ?>

<?php if ( have_posts() ) : ?>
<?php while ( have_posts() ) : the_post(); ?>
    <?php the_content(); ?>
<?php endwhile; ?>
<?php endif; ?>

<? echo $responseModal; ?>

在Wordpress的页面编辑器中，我有启动表单模式的代码（以及与本主题无关的其他html）：

联系我们有关餐饮的事宜
点击这里

页面的功能达到触发表单模式的程度，如果必填字段留空，则当用户尝试提交时会出现错误模式。但是，如果表单填写正确，则提交后不会出现成功模式，并且电子邮件不会在接收端收到消息。此外，页面内容消失，在提交失败后，您看到的只是主题模板。错误代码工作正常对我来说毫无意义，但它只有在实际提交时才会中断。

试试这个，更改：

<form method="post">

致：

<form method="post">

<form role="form" action="<?php the_permalink(); ?>" method="post">
