Couple of things, firtsly could you use code tags to place code in a post.
Secondly welcome to the forums.
OK one of your first problems was your initial for statement had seom variables named wrongly
for($cvchk = 1; $cchk <= $c; $cchk ++)
then there were a few other problems to such as at no point were you specifying to start from any number other than 1, so it would always count from 1-4.
you were also echoing the value of cchk for no reason.
here is the code i come up with not the best for many reasons, such as im not a great programmer/scripter plus i don't know the PHP language but here it is anyway
<?
$c = $_POST['col'];
$r = $_POST['rw'];
?>
<?
for($cvchk = 1; $cvchk <= $c; $cvchk ++)
{
$x = $cvchk;
for($rchk = 1; $rchk <= $r; $rchk ++)
{
if ($x > 4)
{
$x = 1;
}
echo $x." ";
$x += 1;
}
echo "<br />";
}
?>
As you can see i also check to see if x goes above 4 if so it returns it to 1, this ensure that it doesn't produce this outcome
1234
2345
3456
4567
Also this is unchecked but to make this work for any number of rows, so the highest number = the number of ros simple change this
if ($x > 4)
{
$x = 1;
}
.....
if ($x > $r)
{
$x = 1;
}
Hope this helped if you need anything else just ask.
