[SOLVED] conditional if statements not working in FireFox

[ostig]

I have an authentication script that checks for the validity of userid/password entered on a form by comparing to a table in MySQL. The script works fine in IE and Safari, but does not work in FireFox.

 

There are two conditional IF statements that are apparently not being processed when the user is in the FireFox browser, allowing them to enter in invalid data (or no data) and gain access because the script falls through to the "success" part of the code.

 

The IF statements:

//User Not Found
if(!$result || (mysql_numrows($result) < 1)){
    echo "<meta http-equiv='refresh' content='0;url=baduser.php?From=$olive&User=$user1'>" ;
    $baduser = "1";
    }

//See if the password for the user is correct
if ($baduser == "0") {
$query = "SELECT * FROM subscribers WHERE username='$user1' AND userpass='$pass1'";
$result = mysql_query($query)
    or die ("could not execute query");
    if(!$result || (mysql_numrows($result) < 1)){
    echo "<meta http-equiv='refresh' content='0;url=badpass.php?From=$olive&User=$user1'>" ;
    }
}

 

I am new to PHP , I am assuming there is a way around this but - no clue. Any pointers appreciated.

 

Thanks in advance.

The problem will be with your html not php,

 

php is server side and will not be affected by different browsers

This code is not browser dependent. Is this the whole script?

 

Instead of echoing <meta refresh tags for redirection use

 

header("Location: badpass.php?From=$olive&User=$user1");

if you want it all done in php try it like this;

 

//User Not Found
if(!$result || (mysql_numrows($result) < 1)){
    header('Location: baduser.php');
    exit();
    }

//See if the password for the user is correct
if ($baduser == "0") {
$query = "SELECT * FROM subscribers WHERE username='$user1' AND userpass='$pass1'";
$result = mysql_query($query)
    or die ("could not execute query");
    if(!$result || (mysql_numrows($result) < 1)){
       header('Location: baduser.php');
    exit();
    }
}

Unbelievable, the speed and the accuracy of the responses here on PHPFreaks.

 

Thank you BOTH so much for the help, the script is working now. Plus I have a new command to learn about, "header".

 

Cheers!
