Question

I am using this code on my website (It is included in 404.php):

<?php 
if (isset($_POST["op"]) && ($_POST["op"]=="send")) { 

/******** START OF CONFIG SECTION *******/
  $sendto  = "[e-mail]";
  $subject = "Website Contact Enquiry";

/******** END OF CONFIG SECTION *******/



  $message = $HTTP_POST_VARS['message']; 
  $headers = "From: $email\n";
  $headers . "MIME-Version: 1.0\n"
           . "Content-Transfer-Encoding: 7bit\n"
           . "Content-type: text/html;  charset = \"iso-8859-1\";\n\n";

$request = $_SERVER["REQUEST_URI"];
$self = $_SERVER["PHP_SELF"];
// Build the email body text
  $emailcontent = " 
----------------------------------------------------------------------------- 
   WEBSITE CONTACT ENQUIRY
----------------------------------------------------------------------------- 
$request
$self

$message


"; 
 if (!trim($message)) { 
  echo "<p>Please go back and type a Message</p><p><a href='javascript: history.go(-1)'>Click here to go back</a>.</p>"; 
}  


// Sends out the email or will output the error message 
 elseif (mail($sendto, $subject, $emailcontent, $headers)) { 
  echo "<br><br><p><b>Thank You </b></p><p>We will be in touch as soon as possible.</p>"; 

} 
} 
else { 
?>

And this is my form

<form action="http://www.ahornblume.ch/404.php" method="post">
<INPUT NAME="op" TYPE="hidden" VALUE="send"> 
<textarea name="message" cols="25" rows="4" placeholder="Wenn Sie eine Antwort wünschen,  vergessen Sie bitte ihre email Adresse nicht."></textarea><br>
<input name="submit" type="submit" value="Send Message"> 
</form> 

I am redirecting all 404 errors in my htaccess file like so:

ErrorDocument 404 /404.php

If I go to ahornblume.ch/404.php everything works and I can use the form to send emails.
But, if I go to ahornblume.ch/something the contact form doesn’t work.

Answer 1

Your form does not have an action specified so it will submit to the URL that was used to display the form.

In case of ahornblume.ch/404.php it will submit to 404.php and it will work.

In case of ahornblume.ch/something it will result in a 404 error that will just display the 404.php page, but the form post will have been discarded.

To fix, specify an action with an absolute path/404.php
