PHP重定向問題

Question

我很難讓頁面在表單提交後重定向。我遵循了迄今爲止能夠找到的建議，但沒有運氣。任何幫助將不勝感激。

<?php 
//If the form is submitted 
if(isset($_POST['submit'])) { 

$subject = "CONTACT FORM"; 
//Check to make sure that the name field is not empty 
if(trim($_POST['contactname']) == '') { 
    $hasError = true; 
} else { 
    $name = trim($_POST['contactname']); 
} 

//Check to make sure sure that a valid email address is submitted 
if(trim($_POST['email']) == '') { 
    $hasError = true; 
} else { 
    $email = trim($_POST['email']); 
} 

//If there is no error, send the email 
if(!isset($hasError)) { 
    $emailTo = 'email@domain.com'; 
    $body = "Name: $name \nEmail: $email"; 
    $headers = 'From: Bond Limo (Newsletter Signup) <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email; 

    mail($emailTo, $subject, $body, $headers); 
    $emailSent = true; 

    } 
} 
?> 

    <?php if(isset($hasError)) { //If errors are found ?> 
    <p class="error">Please check if you've filled all the fields with valid information. Thank you.</p> 
    <?php } ?> 
    <?php if(isset($emailSent) && $emailSent == true) { 

    header("Location: http://www.website.com"); 

    } 
    ?> 

    <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" class="side-form">

您的頭文件未被處理。爲了處理標題並重定向，您必須在標題後調用die()函數。像這樣：

<?php 
    if(isset($emailSent) && $emailSent) { 
     header("Location: http://www.website.com"); 
     die(); 
    } 
?> 

此外，您的代碼可以通過不再檢查：<?php if(isset($hasError)) { //If errors are found ?>再次優化。相反，只是上面的連接，如果語句，並使用else語句，像這樣：

// If there is no error, send the email 
if (!isset($hasError)) { 
    $emailTo = 'email@domain.com'; 
    $body = "Name: $name \nEmail: $email"; 
    $headers = 'From: Bond Limo (Newsletter Signup) <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email; 

    $emailSent = mail($emailTo, $subject, $body, $headers); 
} else { 
    // Errors found 
    <p class="error">Please check if you've filled all the fields with valid information. Thank you.</p>
