That and,
$sql=mysql_query ("SELECT * FROM tbl_posts WHERE post_id = '$id'");
will work just fine if you are sure you need quotes around $id, or just
$sql=mysql_query ("SELECT * FROM tbl_posts WHERE post_id = $id");
if not... all that quoting when there is no need to can drive a person
crazy!
Try:
session_start();
require_once('db.inc.php');
if(!isset($_GET['id']))
{ // request variable 'id' is not set, dump back to main
header('Location: main.php');
}
else
{ // request variable 'id' is set, let's get the data
// add any error checking on 'id' here, ie: $_GET['id'] < 0, etc.
mysql_select_db('tbl_posts')
$sql=mysql_query("SELECT * FROM tbl_posts WHERE post_id = $_GET[id]");
// this line is not a typo!
$r=mysql_fetch_array($sql);
}
.... also, you can substitute $_GET and $_POST with $_REQUEST if you don't
care how 'id' is passed to your script.
