php embeded in html after first submit html disappear

["Janet N" <janet9k@xxxxxxxxx>]

Hi there,

I have two forms on the same php page.  Both forms has php embeded inside
html with it's own submit button.

How do I keep the second form from not disappearing when I click submit on
the first form?  My issue is that when I click the submit button from the
first
form (register), the second form (signkey) disappear.  Code below, any
feedback is appreciated:


<form name="register" method="post" action="/DKIMKey.php">
<input type="submit" name="register" value="Submit Key">

<?php
if (isset($_POST['register']))
{
       $register = $_POST['register'];
}
if (isset($register))
{
       $filename = '/usr/local/register.sh';
       if(file_exists($filename))
       {
               $command = "/usr/local/register.sh ";
               $shell_lic = shell_exec($command);
                echo "<font size=2 color=blue>$shell_lic</font>";
       }
}
?>
</form>



<form name="signkey" action="/DKIMKey.php" method="post">  <label
domain="label">Enter the domain name: </label>
<input name="domain" type="text"> <input type="submit" name="makesignkey"
value="Submit"

<?php
if (isset($_POST['makesignkey']))
{
        $makesignkey = $_POST['makesignkey'];
}
if (isset($makesignkey))
{
  if(isset($_POST['domain']))
  {
        $filename = '/usr/local//keys/generatekeys';
        if(file_exists($filename))
        {
                $domain = $_POST['domain'];
                $command = "/usr/local/keys/generatekeys " . $domain;

                $shell_createDK = shell_exec($command);
                print("<p><font size=2
color=blue>$shell_createDK</font></p>");
        }
  }
?>
</form>
