//This gets 'away' or 'online':
//(Or something like it in your tables)
$query = "select status from whatever where username = '$username';
.
.
.
//Choose a table based on their logged in status:
if ($status == 'away'){
$table = 'away_table';
}
else{
$table = 'online_table';
}
//Now build a query with that table:
$query = "select stuff from $table where username = '$username'";
This is just ONE way of doing it.
Depending on your table structure, there could be other, better, faster
ways to do it.
We'd need to know more about the 'away' and 'online' table[s] and a bit
more info to really help you...

That doesn't even look like PHP code. In PHP variables have $ in front
of them, and you are only sending a query, you aren't assignining
anything to the variables. And further, your actual SQL query is
already applying that restriction, so any usernames returned by the
query will by definition have their seatnums be set to 'seat1' in the
database.

Re: [PHP] if then else statement not working
What am i doing wrong here, the output is always 'empty'
if (seatnum == seat1) {
echo username;
} else {
echo 'empty';
}
?>
Just guessing since I'm not sure what you're trying to do, but...
$result = mysql_query("SELECT username FROM users WHERE seatnum='seat1'")
or die(mysql_error());
list($username) = mysql_fetch_array($result, MYSQL_NUM);
if ($seatnum == "seat1") {
echo $username;
}else {
echo 'empty';
}
?>
What I'm not seeing is where you set $seatnum in the first place and why
you're doing the if/else at all since your mysql query will only return a
username *if* seatnum='seat1' already so the above code I'm guessing will
always print out $username (or blank if the query returns no results).
Anyway, the above should get you going in the right direction...

mysql_query() returns a resource, not the results themselves.
read: http://us3.php.net/manual/en/function.mysql-query.php especially
the 2nd example to see what else you need to do to get to your results.
hint: mysql_fetch_assoc()

It was something like
if ( a=b ) ? a=1 ; a=2;
$a = ($a == $b) ? 1: 2;
which meand: if $a is equal to $b then set $a to 1 otherwise set $a to
2. that is equivalent to:
if ($a == $b) {
$a = 1;
} else {
$a = 1;
}
btw: its called the 'tertiary' syntax (because its the third form)
Anybody know what the correct syntax is?

Re: [PHP] if... then... else with HTML
Alternatively, and this is what I would do because it would be easier to
maintain should you want to change the content later on, you could use
includes as per the following:
\n\nTry This\n\n\n");
if(condition)
include("html_block_1.html");
else
include("html_block_2.html");
print("\n");
?>
I suppose it would depend on how big your HTML blocks are.
Either way -- using includes or using the method below -- will work, and
with neither method will you have to escape out your special characters.
