[Templates] Using array indexes

[John Wang]

I just started using TT and had a question about iterating over an array. I want to put a fixed number of array items on a HTML row. Something like the following:

# Have an array of hash:
my @array = map {{id=>"abc$_"}} (1..99);
my $aref = [EMAIL PROTECTED];
my $vars = {
  aref => $aref
};

# Want to mimic this in template:
for ([EMAIL PROTECTED]) {
  print "<tr>" if $_ == 0;
  print "<td>$aref->[$_]{id}</td>";
  print "</tr>\n<tr>" unless ($_+1)%4;
  print "</tr>" if $_ == [EMAIL PROTECTED];
}

# To get this output:
<tr><td>abc1</td><td>abc2</td><td>abc3</td><td>abc4</td></tr>
<tr><td>abc5</td><td>abc6</td><td>abc7</td><td>abc8</td></tr>
<tr><td>abc9</td><td>abc10</td><td>abc11</td><td>abc12</td></tr>
<tr><td>abc13</td><td>abc14</td><td>abc15</td><td>abc16</td></tr>

I know how to do a simple iteration using [% FOREACH aref %] and I know about aref.size which would give the equivalent of scalar(@$aref) but I'm not sure how to accomplish the above. Any help would be great.

Thanks,
John
