How to pass SELECTED value from form

[DaPrince]

Need help on how to pass the selected value in a form to the DB

Here goes

echo "<form name=\"Register\" action=\"modules.php\" method=\"post\">";

some irrelevant code
..
..
and then the select box

 
echo "<select name=\"user_avatar\" onChange=\"showimage()\" class=\"pn-normal\">";
                  $handle = opendir('images/avatar');
                   while ($file = readdir($handle)) {
                            $filelist[] = $file;
                        } 
                        asort($filelist);
                        while (list ($key, $file) = each ($filelist)) {
                            ereg(".gif|.jpg", $file);
                            if ($file != "." && $file != ".." && $file != "index.html" && $file != "CVS") {
                                echo "<option value=\"$file\"";
                                if ($file == $user_avatar) {
                                    echo " selected";

                            } 
                            echo ">$file</option>";

                        } 

                    }


		echo "</select>";



		echo "</font></td>"			
	."</tr>";
		echo"</table>";
			echo "<table align=\"center\" width=\"100%\" bgcolor=\"$bg_color2\" cellspacing=\"1\" cellpadding=\"3\" border=\"0\">";
			echo"<tr>"
				."<td width=\"50%\" bgcolor=\"$bg_color2\" align=\"center\"><font class=\"pn-normal\">"
					."<input type=\"hidden\" name=\"profileid\" value=\"$profileid\">"
					."<input type=\"hidden\" name=\"user_avatar2\" value=\"$user_avatar\">"
					."<input type=\"hidden\" name=\"module\" value=\"".$ModName."\">"
					."<input type=\"hidden\" name=\"req\" value=\"DoModifyMember\">"
					//."<input type=\"hidden\" name=\"authid\" value=\"" . pnSecGenAuthKey() . "\">"
					."<input type=\"submit\" value=\""._SAVECHANGES."\"></form></td>
				</tr>";
			echo"</table>";

and then show the selected image chosen from the SELECTBOX (and JavaScript function)

<img src=\"images/avatar/$avatar\" name=\"avatar\" alt=\"$file\" align=\"top\">

The JavaScript onChange code

function showimage()
{
if (!document.images)
return
document.images.avatar.src= 'images/avatar/' + document.Register.user_avatar.options[document.Register.user_avatar.selectedIndex].value
}

The dropdown works excellent. The value I need passed is the selected image from the dropdown-box.

Hope You get what I need

Hi,

you can get the posted value with e.g.

$avimg = $_POST['user_avatar'];
