q1)
i got a database with 2 diffrent tables,
i want to take out all the information that arent duplicated from
on of the tables, like this:
$sql = "SELECT t1.rubrik, t1.info, t2.priser FROM table1 AS t1, table2 AS t2
WHERE t1.arkiv = '0' ORDER BY t1.rubrik";
[/snip]
It's a SQL question, but I'll answer...
$sql = "SELECT DISTINCT(t1.rubrik), t1.info, t2.priser FROM table1 AS t1, table2 AS t2
WHERE t1.arkiv = '0' ORDER BY t1.rubrik";

q2)
i got like 100 matches from a database into a $num variable,
then i want to devide that by 3 aslong as it can be done, eg:
while ($num != 0) {
ïf ($num / 3 = true){
some code to display some fields from a database
$num = $num - 3;
}
else {
some other code to display
$num = 0;
}
}
basicly i want the if statement to check if its more then 3 posts left to
print out, if not its gonna print out the remaining last 1 - 2 post in a
diffrent way (for the looks)
[/snip]
if(($num / 3) == true)
Happy Holidays!
