secure md5 authentication with mysql

I have added users into my mysql database using
$password = "mypassword";

$secure_password = md5($password);
mysql_connect(etc...etc...)
INSERT INTO dbname etc...

Anyway, that all works fine, but no I want to authenticate users securely using my login page.

My fields are user_name & user_pass. I have connected to my database but can't authenticate users correctly.

I have tried...

$access_password = md5($user_pass);

if($user_pass == "username" && $access_password == "password"); but to no avail!

Suggestions and help appreciated

Thanks

RE: secure md5 authentication with mysql

Try to get the line according to user/password using something like:

php Code:

Original - php Code
<?php $r = mysql_query( "select from users where username = '$user_pass' and password = '".md5($access_password)."'" ); if ( mysql_numrows( $r ) < 1 ) { die( "Access Denied" ); } else { // Access granted } ?>

 
<?php
$r = mysql_query( "select from users where username = '$user_pass' and password = '".md5($access_password)."'" );
 
if ( mysql_numrows( $r ) < 1 ) 
{
  die( "Access Denied" );
}
else
{
  // Access granted 
}
?>
