I started learning PHP about 2 weeks ago and have gotten as far as small database things..
I decided as a first project I would make some sort of system for my school library, however I can't see what is wrong with this code. The page shows up blank (I had a "or die()" after the mysql_connect function) with no info on it.
<?php
$var = $_POST['bookid'];
if(isset($var)) {

$con = mysql_connect("localhost","root","1234");
mysql_select_db("library");
$bookinfo = mysql_query("SELECT * FROM books WHERE bookid = $_POST['bookid']");
while($row = mysql_fetch_array($bookinfo))
{
echo $row['bookid'] . $row['id'];
}
}
echo "Test echo";
?>

The form sending the POST data sends <input type="text" name="bookid"/>
I am able to connect to the mysql db as I have tried with another page (which simply shows text on it from a db).
The "Test echo" does not show.
Anybody able to shed some light on this?
