[RESOLVED] Someone Please Explain Me These...

[fr600]

I don't understand the underlined portion:

$res1 = mysql_query("UPDATE articles SET updated = NOW() WHERE id = \"$id\"".($hash=="" ? "" : " AND hash='$hash'"));
$res2 = mysql_query("UPDATE articles SET updated = NOW() WHERE id = \"$id\" AND clicks=0".($hash=="" ? "" : " AND hash='$hash'"));

Can anyone please explain me these?

Perhaps you're looking for an explanation of the ternary operator?

I have read that now but I find it difficult to understand. Is there any easyier way to write those 2 queries?

You should think of the ? as the words "then do" and the : as "else".

So basically, you have:

<?php
echo([b]([/b]If Statement[b])[/b] [b]?[/b] "then do statement"  [b] : [/b] "else statement");
?>

If the "IF Statement" is true, we do the "Then do statement", else, we do the "else statement".

OK, now I understand. Thanks.
