PHP表单重定向到PHP文件本身

我试图让一个联系人表单工作，我被重定向到PHP文件本身，我不知道为什么。我对PHP相当陌生，我不完全确定自己做错了什么。我希望被指向正确的方向。代码如下

谢谢

HTML:

请填写所有字段*

PHP:

---

这一行告诉表单将数据发送到哪个PHP文件：

<form id="contact_us" enctype="text/plain" method="post" action="form.php">

事实上，这很好。可以在包含表单的同一PHP文件中处理表单。只需将PHP表单处理放在顶部：

<?php

    if (isset($_POST['Email_Address'] && $_POST['Email_Address'] != ''){
        $to = 'zack@zfisch.com';
        $subject ='Dropset Work Request';

        $name = $_POST['Name'];
        $company = $_POST['Company'];
        $email = $_POST['Email_Address'];
        $message = $_POST['Description'];
        $message = <<<EMAIL

        From: $name

        $message

        Email: $email   

EMAIL;

        $header = $subject;

        if($_POST) {
        mail($to, $subject, $message, $header);
        $feedback = 'Email sent!';
        }
    }else{
>?
<p id='feedback'><?php echo $feedback; ?></p>
<form id="contact_us" enctype="text/plain" method="post" action="form.php">
    <input class="form_field" type="text" name="Name" placeholder="Full Name">
    <br>
    <input class="form_field" type="text" name="Company" placeholder="Company Name">
    <br>
    <input class="form_field" type="email" name="Email_Address" placeholder="Email Address">
    <br>
    <textarea class="form_field" rows="10" cols="20" name="Description" wrap="hard" placeholder="Project Description"></textarea>
    <br>
    <p id="required"><i>Please fill in all the fields*</i></p>
    <input class="submit" type="submit" value="SUBMIT">
</form>
<?php
    }
?>

只需删除
enctype=“text/plain”
即可，否则您的代码在HTML中是正确的，并尝试
回显反馈变量另一种方法是将所有代码写入HTML之上，如下所示：

     <?php

    if (isset($_POST['Email_Address'] && !empty['Email_Address']){
        $to = 'zack@zfisch.com';
        $subject ='Dropset Work Request';

        $name = $_POST['Name'];
        $company = $_POST['Company'];
        $email = $_POST['Email_Address'];
        $message = $_POST['Description'];
        $message = <<<EMAIL

        From: $name

        $message

        Email: $email   

        $header = $subject;

        if($_POST) {
        mail($to, $subject, $message, $header);
        $feedback = 'Email sent!';
        }
    }else{
>?
<p id='feedback'><?php echo $feedback; ?></p>
<form id="contact_us" enctype="text/plain" method="post" action="form.php">
    <input class="form_field" type="text" name="Name" placeholder="Full Name">
    <br>
    <input class="form_field" type="text" name="Company" placeholder="Company Name">
    <br>
    <input class="form_field" type="email" name="Email_Address" placeholder="Email Address">
    <br>
    <textarea class="form_field" rows="10" cols="20" name="Description" wrap="hard" placeholder="Project Description"></textarea>
    <br>
    <p id="required"><i>Please fill in all the fields*</i></p>
    <input class="submit" type="submit" value="SUBMIT">
</form>
<?php
    }
?>

删除
enctype=“text/plain”
，此
$header=$subject将失败。阅读手册@Fred ii-仍然重定向到浏览器中的form.php，一个空白页面，尝试回应$feedback；$feedback之后='Email sent！'；由于
form.php
不回显任何内容，因此预期结果是空白页面。您应该通过
header
函数重定向到另一个地方，或者在脚本末尾回显某个内容。。。重定向回当前php文件或处理当前php文件中的请求。heredoc结束标识符前的空格不应存在。理论上，这将抛出一个解析错误。埃雷多克：
action="form.php"
