HELP!! If statement problem..
hi everyone, i'm a very newbie in wap programming. I'm creating my first wap system and there is a problem which i could not solve even i have tried a lot of samples.
The problem is in the if statement which comparing the variable with database value for login. Below is the code: Code:
<?php
session_start();
session_register('username');
header("Content-type: text/vnd.wap.wml");
echo "<?xml version=\"1.0\"?>";
echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""
. " \"http://www.wapforum.org/DTD/wml_1.1.xml\">";
?>
<wml>
<card id ="card1" title="Ordering">
<p>
<?
print '$category--<br/>';
if ($category == 'chinese')
print "Yes!!";
else
print "NO!";
?>
</p>
</card>
</wml>
The value of $category is empty when it is in the IF statement. But when I print '$category'; the value is there. HELP... and Thanx..

Where does $category come from?
Your php should be PHP Code:

ooh... Thanks a lot, it is working now. But now i've encountered a new problem.
Code:
//Generate random number
$salt = "abchefghjkmnpqrstuvwxyz0123456789";
srand((double)microtime()*1000000);
$i = 0;
while ($i <= 7)
{
$num = rand() % 33;
$tmp = substr($salt, $num, 1);
print " $pass = $pass . $tmp";
$i++;
}
print '$pass--<br/>';
The variable in $pass is empty, also when i print the $pass = $pass.$temp. Thanks for your help. I'll really appreciate it.
