PHP标头（位置：）重定向是否需要指向以“ http：//”开头的网站？

Question

I'm doing a bit of web development for a client of mine, and I've run into a roadblock.

**Here's what's going on: **

-We have multiple copies of the same contact form on our website, but we want each to redirect to a different landing page upon completion in order to track conversion rates.

-In this example, I'm working on the about page. When a user submits their request for more information, the page would ideally redirect to a unique Thank-You page (eg, www.sample.com/thank-you-about.html); however, it's not.

-The email will get sent off perfectly, but the redirection will never take place. No errors are thrown - nothing.

BEFORE I show the code, here's what I've tried in order to solve it on my own:

-I've created a body of HTML code underneath the .php code that the form sends its input to. To my knowledge, no redirect is taking place, so I've obviously not seen it yet.

-I've used the call "Header(Location:www.sample.com/thank-you-about.html)", but that's not doing anything either.

-I've tried using Javascript's "frame.location" method, and it doesn't seem to get any further than the php attempt.

-I've saved the source page and destination page as .php pages on the off-chance that using an .html extension is at the root of the problem; same outcome.

Really, the only thing left that I can think of is the connection type not satisfying the requirements for a Header() call. But wouldn't that output an error message?

Here's the contact form in question:

 <form id="contactForm" class="get-in-touch contact-form light" action="thank-you-about.php" method="post">
                        <input type="hidden" id="contact_nonce" name="contact_nonce" value="68592e213c"/><input type="hidden" name="" value="/"/>
                        <input type="hidden" name="contact-form-value" value="1"/>
                        <div class="iconic-input">
                            <input class="name" type="text" name="name" placeholder="Name*">
                            <i class="icons icon-user-1"></i>
                        </div>
                        <div class="iconic-input">
                            <input class="email" type="text" name="email" placeholder="Email*">
                            <i class="icons icon-email"></i>
                        </div>
                        <textarea class="msg" name="msg" placeholder="Message"></textarea>
                        <input type="submit" value="Send Message">
                        <div class="iconic-button">
                            <input type="reset" value="Clear">
                            <i class="icons icon-cancel-circle-1"></i>
                        </div>
                    </form>

Here's the current .php file, thank-you-about.php:

    <?php

// Define some constants
define( "RECIPIENT_NAME", "Sample" );
define( "RECIPIENT_EMAIL", "writewoodcopy@gmail.com" );
define( "EMAIL_SUBJECT", "New request from site sample webpage" );

// Read the form values
$success = false;
$senderName = isset( $_POST['name'] ) ? preg_replace( "/[^\.\-\' a-zA-Z0-9]/", "", $_POST['name'] ) : "";
$senderEmail = isset( $_POST['email'] ) ? preg_replace( "/[^\.\-\_\@a-zA-Z0-9]/", "", $_POST['email'] ) : "";
$message = isset( $_POST['msg'] ) ? preg_replace( "/(From:|To:|BCC:|CC:|Subject:|Content-Type:)/", "", $_POST['msg'] ) : "";
$messageInterests = "";
$subject = "";
$currentURL = isset($_POST['current-URL'])? $_POST['current-URL'] : "";

//Parse checkboxes, include them in message body
$interestArray = $_POST['interest'];
if(!empty($interestArray)){
    $messageInterests .= "INFORMATION OF INTEREST:   ";
    $N = count($interestArray);
    for($i = 0; $i < $N; $i++)
    {
        $messageInterests .= "\r\n" . $interestArray[$i];
    }
    $subject .= $messageInterests . "\r\n \r\n";
}
else {
    $subject = "GENERAL INQUIRY \r\n \r\n";
}

$subject .= $message;
$message = $subject;

// If all values exist, send the email
if ( $senderName && $senderEmail && EMAIL_SUBJECT && $message ) {
  $recipient = RECIPIENT_NAME . " <" . RECIPIENT_EMAIL . ">";
  $headers = "From: " . $senderName . " <" . $senderEmail . ">";
  mail( $recipient, EMAIL_SUBJECT, $message, $headers );
  header("Location: www.sample.com/thank-you-about.html"); /* Redirect browser */

}

?>

EDIT:: Before anyone asks, I know that no checkboxes are being parsed from this particular contact form. They come in handy on my client's service pages, while general inquiries are handled by the about page, contact us page, and homepage.

SECOND EDIT:: So, I fixed the absolute URL problem; however, the redirect problem is still persisting. Thank you all for being so patient!

Answer 1

Does a PHP Header(Location:) redirect need to point to a website starting with “http://”?

Yes, if you need to redirect to a file on a different domain , you'll have to specify the full absolute URL , this includes the protocol ( http , https , etc.), based on that, this doesn't work :

header("Location: www.sample.com/thank-you-about.html");

use:

header("Location: http://www.sample.com/thank-you-about.html");

---

If you need to redirect to a file on the same domain you can use a relative path:

header("Location: thank-you-about.html"); //thank-you-about.html is located on the same dir as the current script

or

header("Location: /thank-you-about.html"); //thank-you-about.html is located on the root dir of the domain

---

header() is used to send a raw HTTP header. See the » HTTP/1.1 specification for more information on HTTP headers.

Read more about the php header() function.

Answer 2

My suggestion would be to pass the redirect parameter as part of the action attribute, ie

     ...action="sendEmail.php?redirect=thank-you-about" method="post">

Then read it out server side and redirect accordingly.

 // do your sending email logic here, then redirect:
 $r = $_GET['redirect];
 switch($r){
   case: 'thank-you-about':
     header("Location: /thank-you-about.html"); die();
     // it might be tempting to go 'header("Location: /$r")' directly, but this would introduce quite a security vulnerability.

   break;

   case: 'otherpage':
    header("Location: /thank-you-other.html"); die();
   break;

   default:
      header("Location: /thank-you-default.html"); die();
   break;
  }
