如何让我的PHP表单重定向工作？

Question

我创建了一个包含以下html和php代码的表单，基本上它运行检查以查看垃圾邮件问题是否已成功完成，在这种情况下它应该处理表单，发送电子邮件并将用户重定向到thankyou .html页面。 但是，目前，成功时，表单只是重新加载相同的页面，并没有重定向到感谢页面，但是我收到了确认电子邮件...

在下面的代码中是否有一些我错过/出错的东西来阻止这个行动？

<form id="form" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
    <table>
        <tr>
            <td align="right"><label for="name">Name:<span class="error"><?php echo $nameErr;?></span></label></td>
            <td><input type="text" name="name" id="name" /></td>
        </tr>
        <tr>
            <td align="right"><label for="email">Email:<span class="error"><?php echo $emailErr;?></span></label></td>
            <td><input type="text" name="email" id="email"  /></td>
        </tr>
        <tr>
            <td align="right"><label for="telephone">Telephone:<span class="error"><?php echo $telErr;?></span></label></td>
            <td><input name="telephone" type="text" id="telephone" /></td>
        </tr>
        <tr>
            <td align="right"><label for="field">Anti-spam question:<span class="error"><?php echo $spamErr;?></span></label></td>
            <td><input name="field" type="text" id="field" value="Complete the Beatles lyric: all you need is...?"  onfocus="if(this.value==this.defaultValue) this.value='';"  onblur="if(this.value == ''){this.value='Complete the Beatles lyric: all you need is...?';}" /></td>
        </tr>
        <tr>
            <td align="right"><label for="message">Message:</label></td>
            <td><textarea name="message"></textarea></td>
        </tr>
        <tr>
            <td colspan="2" align="right"><img src="images/contactdots.gif" width="338" height="10" alt="" /></td>
        </tr>
        <tr>
            <td colspan="2" align="right"><input id="button" type="Submit" value="SUBMIT" alt="submit" /></td>
        </tr>
    </table>
<?php

if($_SERVER['REQUEST_METHOD'] == "POST"){

// Pick up the form data and assign it to variables
$name = stripslashes($_POST['name']);
$email = stripslashes($_POST['email']);
$tel = $_POST['telephone'];
$comments = stripslashes($_POST['message']);
$field = strtolower($_POST['field']);
$spam_check = 'love';
if($field == $spam_check){
// Build the email (replace the address in the $to section with your own)
$to = 'my@email.com';
$subject = "The Vintage Affair Web Quote enquiry";
$comments = "Name: $name \nEmail: $email \nTelephone: $tel \n\nDetails: $comments";
$headers = "From: my@email.com" . PHP_EOL . "Reply-To: my@email.com";

// Send the mail using PHPs mail() function
mail($to, $subject, $comments, $headers);

// Redirect
header("Location: thankyou.html");
}
else{ echo '<div class="spam">*You got the Beatle\'s lyric wrong, please try again*</div>'; }
}

?>
</form>

Answer 1

问题是你在调用header（）之前输出数据，它不会像这样工作。

将所有PHP放在表单上方。

Answer 2

header()必须在ANY输出之前发送，如果它是空格或字符串。

您必须先检查表单提交，如下所示：

<?php

if( isset($_POST['myform'] )
{
 if( spam_check($_POST['myform']) === true )
 {
   header("Location: thankyou.html");
 }
 else 
 { 
  echo '<div class="spam">*You got the Beatle\'s lyric wrong, please try again*</div>';
 }
}
else
{
  display_form();
}
?>

dispay_form（）是一个显示所有HTML的函数，可能是HTML文件的file_get_contents() 。

Answer 3

我遇到了同样的问题，我找到了这个解决方案：

if (!headers_sent()){
    header('Location: thankyou.html');
}
else {
    echo '<script>';
    echo 'window.location.href="thankyou.html";';
    echo '</script>';
    echo '<noscript>';
    echo '<meta http-equiv="refresh" content="0; url=thankyou.html" />';
    echo '</noscript>';
}

我希望它对你有用

Answer 4

试试吧：

header("Location: thankyou.html");
exit();

Answer 5

好吧，问题是你在运行支票之前实际输出了屏幕上的内容。 在您输入HTML代码的任何输出之前发送标头。

使用ob_start（）; ob_end_flush（）函数; 在文件的开头配对的东西

<?php 
   ob_start(); // this stores the output in a buffer for later use
?>

html code here

<?php



if($_SERVER['REQUEST_METHOD'] == "POST"){

    // Pick up the form data and assign it to variables
    $name = stripslashes($_POST['name']);
    $email = stripslashes($_POST['email']);
    $tel = $_POST['telephone'];
    $comments = stripslashes($_POST['message']);
    $field = strtolower($_POST['field']);
    $spam_check = 'love';

    if($field == $spam_check){
        // Build the email (replace the address in the $to section with your own)
        $to = 'my@email.com';
        $subject = "The Vintage Affair Web Quote enquiry";
        $comments = "Name: $name \nEmail: $email \nTelephone: $tel \n\nDetails: $comments";
        $headers = "From: my@email.com" . PHP_EOL . "Reply-To: my@email.com";

        // Send the mail using PHPs mail() function
        mail($to, $subject, $comments, $headers);

        // Redirect
        header("Location: thankyou.html");
   }
    else echo '<div class="spam">*You got the Beatle\'s lyric wrong, please try again*</div>';
}

ob_end_flush(); // this is for printing the buffered output
?>

ob_end_flush（）函数; 在末尾

Answer 6

把表格放在php代码下面
