Say 'no' to disposable emails.



Simple version - 4 steps:

  1. Paste this code instead of your input textfield for the email address:
    <script type='text/javascript' src='http://remailr.com/api/remailr_js.php'>
</script>
  2. Add the following id to your submit button:
    id='remailrSubmitButton'
    e.g.: 
    <input type='submit' name='submitDomain' value='Submit'
class='button' id='remailrSubmitButton'>
  3. Add the following to your form tag:
    onSubmit='return remailrCheckedMail();'
    e.g.: 
    <form name='submitForm' method='post' action='index.php'
id='submitForm' onSubmit='return remailrCheckedMail();'>
  4. Create a file remailr_ajax_call.php with the following content:
    <?php
header("Content-Type: text/xml");
echo file_get_contents("http://remailr.com/api/remailr_ajax_call.php?q=".$_GET['q']);
?>
    This file and the file with your form need to be in the same folder.

Explanation:

  1. The javascript will produce a textfield with the name 'userMail'. The field will be linked via an ajax call to the database of email domains that should be blocked.

  2. The submission of the form is blocked by disabling the submit button. The script disables a button with the id 'remailrSubmitButton' when a blocked email is entered.

  3. This ensures that the user passed by the email field when he clicks submit. The field can be filled after a reload or a back without having been checked.

  4. Cross-site ajax calls are not allowed. The seperate php file makes the ajax call.

A simple subscription form asking for an email address: newsletter.html 
<html>
