help with looping, make rows fill in within a loop, who is the man?

[rchandran0023]

Im trying to implement the "little pic poll" in my site, but in the source its coded to diplay the images and radio buttons in a table, and the way it renders on the screen is in a straight colomn down, i want to have the picts render in like maybe 4 element wide rows going down, so first fill in the first row, then the second, so on. but as it is now it just has the picts showing each under the other. I see the code thats doing this, within the while statements, but cant figure how to do it, by imbeding another loop or what? Ne help MUCH appreciated and i will respect u forever!!

Im showing all the source code, but its not all pertinant to my question. TY.

While it is often useful having plenty of the source code, its more useful having the relevant bit highlighted too us too

 

Also, for future refernce, if you use full php opening tags(<?php) we get syntax highlighting which makes it a whole stack easier to read.

 

Anyways, there is an FAQ on exactly this subject:

Hopefully that might guide you in the right direction.

Use modulus (%) to find out whenever the number of times you've printed data is a multiple of 4, then do a "</tr><tr>". IE.

 

// code

print "<td>data</td>";

if ($times_printed % 4 == 0) {
      print "</tr><tr>";
}

//code
