提交表單後$ _POST中沒有任何值

我剛剛開始使用PHP進行編碼，並且遇到一些問題以使此代碼有效。我試圖從$_POST更改爲$HTTP_POST_VARS，但我仍然無法獲得價值，任何人都可以指出我做錯了什麼，以及如何修復此代碼？

<?php 


$email_address = "[email protected]"; 
// your e-mail address goes here 

$email_subject = "Online Enquiry"; 
// the subject line for the e-mail goes here 

$from_email_name = "[email protected]"; 
// the from address goes here 

$redirect_to_page = "thankyou.html"; 
// enter the web address where the user should be sent after completing the form 

//********************************* 
// DO NOT EDIT BELOW THIS LINE!!!** 
//********************************* 


$mailTo = "$email_address"; 

$mailSubject = "$email_subject"; 

$mailBody = "The form values entered by the user are as follows: \n\n"; 

foreach($_POST as $key=>$value) 
{ 

$mailBody .= "$key = $value\n"; 

} 



$mailBody .= "\n\n"; 


$fromHeader = "From: $from_email_name\n"; 


if(mail($mailTo, $mailSubject, $mailBody, $fromHeader)) 
{ 

    print ("<B><br></b>"); 

} 

echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$redirect_to_page\">"; 

?>

我的HTML表單。

<form action="contact.php" method="post"> 
<input type="text" class="textbox" value=" Your Name" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Your Name';}"> 
<input type="text" class="textbox" value="Your E-Mail" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Your E-Mail';}"> 
<div class="clear"> </div> 
<div> 
<textarea value="Message:" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Your Message ';}">Your Message</textarea> 
</div>       
<div class="submit"> 
<input type="submit" value="SEND " /> 
</div> 
</form>

」並在這個PHP的東西新im「運行時，你在時間的兒子 –

表單提交後嘗試打印'$ _POST）;'。 –

你沒有在$ _POST中使用任何東西。你只是測試是$ _POST不是空的。 '$ key'和'$ value'也是未定義的。你需要一個'foreach（$ _ POST作爲$ key => $ value）'，很可能。 –

請參閱var_dump（$ _ REQUEST）。默認表單提交使用$ _GET對象。「
