RE: [Templates] Using array indexes

[Sergey Martynoff]

 

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. 

The "Table" plugin suits well for this case. You should use "inverted" table (rows becomes cols and vice versa) to get desired output. So rows=3 here really means number of columns.

 

[% USE table(aref, rows=3) %]

<table>
[% FOREACH cols = table.cols %]

    <tr>
    [% FOREACH item = cols %]
        <td>[% item %]</td>
    [% END %]

    </tr>
[% END %]

</table>
