RE: RE: RE: [PHP] cell iterations in loop

Ok, after a few hours of messing here and there I've got it to work. you can adjust for any number of columns, and the pictures and it makes solid tables. Thanks, for all of the help <snip> <table width="450" border="1" align="center"> <?php //set this number to the columns you would like $columns = 7; $pictures = 25;//could be from a database query echo "<tr>\n"; for ($x=1; $x<=$pictures; $x++) { echo "<td>".$x."</td>\n"; if ($x % $columns == 0) { $loopcount++; if ($loopcount < $x ) { echo "</tr>\n"; } else { echo "</tr>\n<tr>"; } } } $test = (($loopcount + 1) * $columns); $td = (($loopcount + 1) * $columns) - ($x -1); if($td != $columns) { for ($x=0; $x<$td; $x++) { echo "<td><b>EMPTY</b></td>\n"; } } #also added in if($x % $columns != 0) { #then we know that it did not end completely, so echo you're final </tr> echo "</tr>\n"; } ?> </table> </snip> Jerry Lake - jerryl@europa.com Interface Engineering Technician Europa Communications - http://www.europa.com Pacifier Online - http://www.pacifier.com -----Original Message----- From: dempsejn@georgetown.edu [mailto:dempsejn@georgetown.edu] Sent: Thursday, April 26, 2001 2:26 PM To: Jerry Lake Cc: php-general@lists.php.net Subject: Re: RE: RE: [PHP] cell iterations in loop ahhhhh, i got it... ok, try this: $length is arbitrary... $x is your counter... do the loop as before, but each time through the loop, $loopcount++; So, if you do the loop 5 times, $loopcount == 5. Then, at the end, $length - ($loopcount*$x) gives you the amount of <td> </td>'s to echo. Put another for loop with these parameters after you've printed your normal td's...you could do this all in one for loop, and would just need some more if statements... i think this is what you need...let me know how it goes... -jack ----- Original Message ----- From: "Jerry Lake" <jerryl@europa.com> Date: Thursday, April 26, 2001 5:20 pm Subject: RE: RE: [PHP] cell iterations in loop > Right, I understand that > if I use <td></td> it is blank space > if I use <td> </td> it is an empty cell > > right now $length is set at 42 (this is arbitrary) > and there needs to be two empty cells at the end of > the last row. if length is 41 I will need 3 and 40 > will need 4. but if I don't know what the value of > $length is going to be on a dynamic page such as > showing "x" amount of images from a folder.
