Redirect upon successful form submission

Hi,

I have 2 pages on php, the first page has a small form to accept a
membership number from the user, which checks for membership number in the
DB, if the membership no does not exist, gives an error saying 'you are not
a member click here to become a member now', this bit works fine.

The problem is the following bit 'if the user is a member, i want the user
to be directed to another page.

this is what i did to get the result since header("Location:....") wont
work, as already the form has been printed on the page.

echo''; but the
problem is that this takes couple of seconds, till then the page is very
much visible which doesnt look good.

Any help on this is much appreciated.

Thanks,
Vinay.

What about holding the form in the buffer, and then dealing with the
buffer before sending the form?

Thanks Bastien,

To be honest I have no clue as to how to hold the form in the buffer. I've
copied the code below, that might help I guess.


include("lib/funcs.php");
$url=$_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'';

}

else
{

$not_member=0;
}


}
?>

Re: Redirect upon successful form submission

you could also validate the form in a seperate php file with no output
and then redirect to the "error" and the "another page" ?

Yep, that would work, but then if the user is not a member, then the link to
the membership should be printed on the form that has the validation and not
the one that has the form?

When you look at it like that all together, I find its easier to
functionalize the whole process


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'';

}
else
{

if($not_member==0)
{
echo 'Our records indicate that you are not a member yet, href="member.php"> Click here to become a member now';
}

}

}//end function processForm

function showForm(){
?>
