opening a URL

I would like some help

Basically I would liek to know how to open a URL depending on whethere a boolena variable is true or not

EG
if (true)
{
open URL etc
}
else
{
open different URL
}

you may consider to use redirecting header function.

header("Location:$url");

Hey can any1 help me....

I get users to login to authenticate and load a page if they have the right access (read in from a database)....

Then if they have access a form is loaded in which they fill it and submit it.......

The problem is when the user submits the information I cannot tell the database which row to put it in, as I can only pass the variables created by the HTML form....there is others (in particular a php variable $memberID which I also need to pass with the form so I can tell the database which row to put it in..........I cannot figure it out....

I would say that the header is your best bet, as rathaur stated. Just use something like

if($loggedIn == true)
header("location: loggedin.php");
else
header("location: error.php");

but remember you can't have any whitespace before outputingg headers on your page. If you do, add ob_start(); to the top of your page to buffer the output.

try using input type of hidden in your form ex:

echo " <input type ='hidden' name='memberID' value=$memberID>";
