网站联系表无法正常工作

Question

我对编码还很陌生，但是我的网站联系表存在问题。填写表格并单击提交按钮后，我将无法接收电子邮件。 我对PHP一无所知，很明显有些东西丢失或不正确。我只包含了文件的相关部分...感谢您能提供的任何帮助！

<div id="page_4"> 
	<div id="wrapper">    
	  <form action="contact form.php" method="post">
		<label for="fname">Name</label>
		<input type="text" name="name" placeholder="Full name...">
		<label for="email">Email</label>
		<input type="text" name="email" placeholder="...">
		<label for="phone">Phone</label>
		<input type="text" name="phone" placeholder="...">
		<label for="subject">Subject</label>
		<input type="text" name="subject" placeholder="..."> 
		<label for="detail">Project Detail</label>
		<textarea name="detail" placeholder="Please use detail if possible..." style="height:200px"></textarea>
		<label for="deadline">Project Deadline (MO/DY/YR)</label>
		<input type="text" name="deadline" placeholder="..."> 
		<a href="mailto:mark@markabove.com"><input type="submit" value="Submit"></a>
	  </form>
	</div>
</div>        

<?php
	
if (isset($_POST['submit'])) {
	
$name = $_POST['name'];	
$subject = $_POST['subject'];	
$mailfrom = $_POST['mail'];	
$message = $_POST['message'];	
	
$mailTo = "mark@markabove.com";	
$headers = "From: ".$mailFrom;
$txt = "You have recieved an e-mail from ".$name."\n\n".$message;	
	
mail($mailTo, $subject, $txt, $headers);
header("Location: contact.html?mailsend");	
	
}
	
?>

表单操作标签的URL中有一个空格。也许将其更改为contact-form.php。
