PHP dropdown sticky
<p>I have a database populated drop down list. </p>

<pre><code>$options4=""; 



    while ($row = mysql_fetch_array($result)) { 

        $id=$row["Client_Code"]; 
        $thing=$row["Client_Full_Name"]; 
        $options4.="&lt;OPTION VALUE=\"$id, $thing\"&gt;".$thing; 
    } 
    ?&gt;

    &lt;FORM name="form" action="&lt;?php echo $_SERVER['PHP_SELF']; ?&gt;" method="POST"&gt;

    &lt;SELECT NAME="ClientNamefour" OnChange="this.form.submit()"&gt;

        &lt;OPTION VALUE=0&gt;Client
        &lt;?php echo $options4?&gt; 

      &lt;/SELECT&gt;
    &lt;/FORM&gt;
</code></pre>

<p>Once this changes it pulls a client name from a database and brings up some information there is a form that can be filled out to insert more information into a database. Once that form is filled out this page sends the information to another page with the code to insert the data into the database. Then I am using a header at the end of that code to send it back to this page. But when it comes back to this page I want it to comeback to the client they selected before and not a blank screen. So how do I make a DB populated list automatically comeback to the previous selection using php?</p>
