When you look at it like that all together, I find its easier to
functionalize the whole process
<?php
include("header.php");
include("lib/funcs.php");
if(isset($_POST['submit'])){
processForm();
}else{
showForm();
}
function processForm(){
$url=$_SERVER['REQUEST_URI'];
$member_no=$_POST['member_no'];
$member_no=trim(htmlspecialchars($member_no));
$not_member=1;
if(isset($_POST['submit']) && $_POST['trigger']==6)
{
// echo $member_no;
$conn = mysql_connect($host,$user,$pass) or die("Could not
open the connection");
$dbselect = mysql_select_db($dbname,$conn) or die("could not
connect to the DB");
$id_query = "SELECT * FROM members WHERE
member_id='$member_no'";
$result = mysql_query($id_query) or trigger_error("SQL",
E_USER_ERROR);
$num_rows = mysql_num_rows($result);
//echo $num_rows;
if($num_rows>0)
{
echo'<META HTTP-EQUIV="refresh"
content="0;URL=member.php">';
}
else
{
if($not_member==0)
{
echo 'Our records indicate
that you are not a member yet, <a
href="member.php"> Click here</a> to become a member now';
}
}
}//end function processForm
function showForm(){
?>
<td width="420" class="whitebg">
<BR />
<h3 align="left">REFERENCE FOR MEMBERSHIP TO INFINITY LEARNERS
CLUB</h3>
<p>
In order to be able to refer members to Infinity LMRC, you need
to
be a registered member with us, Please enter your membership number
below and start referring.</p>
<table width="410">
<form action="<?php echo $url ; ?>" method="post" name="refer" >
<table>
<tr>
<td><label for="memberno">Membership Number</label></td>
<td><input type="text" name="member_no" class="myinput"
/></td></tr>
<tr><td> </td></tr>
<tr><td><input type="submit" name="submit" value=" OK !" /></td>
<td><input type="reset" name="cancel" value=" Cancel "
/></td></tr>
<tr><td><input type="hidden" name="trigger" value="6"
/></td></tr>
</td>
<?php include("footer.php");?>
</table>
</form>
</body>
</html>
<?php
}//end showForm function
?>
This gives way more control over the whole flow
