File redirect after form submission

Hi guys,
Can anyone help with following script below. When a new user signs up to the site. The info is then displayed in this form below in CMS backend. It is then up to the admin to decide on a action and submit the form. There is a section in the CMS that the admin can edit the contacts. When the contact is submitted they want the contact then to be displayed in the edit contacts section. What would be the correct way to do this. I hope I have explained myself correctly.


<p>If there are any applications to process, they will appear in the list below.</p>

<div class="hr"><hr /></div>

<?php

$signups = mysql_find_all("SELECT * FROM SignUps");

foreach ($signups as $r) {

?>

<div class="contactSearchResult">

<table summary="Contact information">
 <tr>
  <td><strong>Name:</strong> <?php echo htmlentities("{$r['first_name']} {$r['last_name']}"); ?></td>
  <td><strong>Phone:</strong> <?php echo htmlentities($r['phone1']); ?></td>
 </tr>
 <tr>
  <td><strong>Job Title:</strong> <?php echo htmlentities($r['title']); ?></td>
  <td><strong>Email:</strong> <?php echo htmlentities($r['email1']); ?></td>
 </tr>
 <tr>
  <td valign="top"><strong>Company:</strong> <?php echo htmlentities($r['company']); ?></td>
  <td valign="top"><strong>Address:</strong><p style="margin-left: 20px;"><?php echo nl2br(htmlentities(preg_replace("/([\
]+)/","\
","{$r['street1']}\
{$r['city1']}\
{$r['country1']}"))); ?></p></td>
 </tr>
 <tr>
  <td align="center" colspan="2">

<form method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>">
<input type="hidden" name="action" value="submit" />
<input type="hidden" name="ID" value="<?php echo $r['id']; ?>" />

<label>Action:</label>
<select name="case">

</select>
<a href=""

</form>
  </td>
