Redirect a login script
Hi,
I try to modify a script produced by Dreamweaver to make each user login to his/hers own page. I have a MySQL database called login with username, password and URL (to the page the individual user will land after login) - but I cannot make it work. So, what is wrong with this code?
mysql_select_db($database_ Liquid_FSt eer, $Liquid_FSteer);
$query_Recordset1 = "SELECT username, password, URL FROM login";
$GLOBALS['MM_UserGroup'] = $loginStrGroup;
$MM_redirectLoginSuccess = mysql_result($LoginRS,0,'U RL');
$Recordset1 = mysql_query($query_Records et1, $Liquid_FSteer) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Records et1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1 );
When I try to run it, I get the following error message:
Warning: mysql_result() expects parameter 1 to be resource, null given in /home/fsteer/public_html/i ndex.php on line 37

Sorry to have to tell you this, but I think you're starting your PHP learning in the wrong place. Dreamweaver contains some of the worst PHP code ever written, and trying to learn from it, use it, or modify it for specialized applications is a fools errand. Instead, buy this little book and give yourself a few weeks to work through the examples. It is very readable and comes with its own code library. And it covers many of the kinds of things that you will be interested in. It will not make you a pro, but it will help you get a good foundation in how PHP and MySQL work together.

I am not trying to learn PHP and I am happy with Dreamweaver. In this case I want to add a field to the login username and password called URL = so that I could redirect each user to its own page. I want to use Dreamweaver's login script and add the URL field to each record. I found this Micromedia article explaing how to do it:
Re: User Login to Redirect using PHP
Hi SoeedRacer21,
Try doing this:
Go back to the original code inserted by the login server behavior. You
don't need to create another recordset to get the page that you should
redirect to. That information can be pulled from the recordset that checks
the username/password. Add 'redirect' to the list of fields being retrieved
"username,password,redirec t".
add this code below "$GLOBALS['MM_UserGroup'] = $loginStrGroup;"
$MM_redirectLoginSuccess = mysql_result($LoginRS,0,'r edirect');
Hope this helps

At the very least, that line Must come After you have run the query, not before. When you run it before, there is nothing for it to get. And '$LoginRS' is supposed to be the results pointer from a query. I don't see a query that is setting that value. This link shows how it is supposed to work:

I do not know .php and I do not want to learn it, hence the reason for using Dreamweaver. I therefore did not understand your answer first time.
$MM_redirectLoginSuccess = mysql_result($LoginRS,0,'U
but mysql_result() is supposed to get the results of a mysql_query() and you haven't run one yet in your code above.
