Rows and cells and rows and cells...

Why isn't this working?? Specifically, why are no rows and cells being printed? All I get is the stuff before and after this segment of code.

code:

foreach $i (@images) 
     {
     if ($i == 0) 
        {
        print "<tr>\n"; 
        }
     elsif ($i > 0) 
        {
        print "<td>something here</td>\n";
        }
     else 
        {
        print "<td> </td>\n";
        }
     $i+=1;
     if ($i == 5) 
        {
        print "</tr>\n";
        $i = 0;
        }
     }

[/code]

Any suggestions would be welcomed!

Make sure you have
print "Content-type:text/html\n\n";

Yes, I do have that...

It is printing the other bits --

code:

print "<table border=0 cellpadding=0 cellspacing=0 bgcolor=\#ffffcc width=450>";
[/code]

Prints and so does:

code:print "</table>\n";
[/code]

Which are the lines above and below the previous snip...

I am thinking there must be something wrong with the list (from my last post about how to get a multi-dimensional list read into the code), but I am at a loss.

I am getting no errors when testing, just nothing in between the table tags.

Ack!

Your problem is that

code:

for $i (@images) { ... }
[/code]

Loops over the ACTUAL ELEMENTS of the array, as opposed to their indices.  I'm not too sure what your code is supposed to do, because of that misunderstanding.

Here's a possible solution:

code:for $img (@images) {
  print "<tr>\n" if !$c++;
  print "<td>$img</td>\n";
  $c = 0, print "<tr>\n" if $c == 4;
}
[/code]
