making ditto output n elements each

I would like to use ditto to output say 3 elements for each <tr> in my table and each of them in a <td> like this:

<tr>
  <td>
     element1 of row1
  </td>
  <td>
     element2 of row1
  </td>
  <td>
     element3 of row1
  </td>
</tr>
<tr>
  <td>
     element1 of row2
  </td>
  <td>
     element2 of row2
  </td>
  <td>
    element3 of row2
  </td>
</tr>

How can I achieve this using a Ditto template?

make your summary template:

<tr>
  <td>
[+element1+]
  </td>
  <td>
[+element2+]
  </td>
  <td>
[+element3]+
  </td>
</tr>

Put the Ditto call inside the <table> </table> tags.

Thank you for your reply but still i do not fully grasp it. How do i tell ditto what [+elementN+] is and how do i control it?

Right now i access the title,id and a custom tv directly (one element at a time) in the following simple summary template:

<a href="[~[+id+]~]">[+title+]</a>
<a href="[~[+id+]~]"><img src="[(base_url)]/[+tvproduct-image-thumb+]" /></a>

I didn’t know it is possible to describe the output of more than one element inside only one summary template. What exactly do i need to do to make that work?

Isn’t that what you want to do with the table?

<table>
[[Ditto? &tpl=`myTpl`.... ]]
</table>

then the myTpl chunk would have the inner part:

<tr>
  <td>
<a href="[~[+id+]~]">[+title+]</a>
  </td>
  <td>
<a href="[~[+id+]~]"><img src="[(base_url)]/[+tvproduct-image-thumb+]" /></a>
  </td>
</tr>

The <tr> ... </tr> part gets repeated for each document being processed.

I believe he is talking about printing the whole ditto items in talbe cells three per row..

You can use the [+item[x]+] placeholder where x is a number of the ditto item

Indeed that is what i am trying to say. Using this approach I’d run into problems though as far as I can tell. Combining the suggestions of both your and susans post I’d get something like this:

<tr>
  <td>
[+item[1]+]
  </td>
  <td>
[+item[2]+]
  </td>
  <td>
[+item[3]+]
  </td>
</tr>

But this would not suffice since it would only refer to the first 3 documents. When I try thinking further I come to the conclusion that i would need to add some kind of offset based on the current [+id+] and the number of documents Ditto has allready processed. However I don’t know how I would achieve this since i php code included in chunks does not get evaluated. Am I missing something? Is there a way to make Ditto aware of the offset i need when i make it process 3 items each loop run?

I hope I described the desired effect sufficiently now. I’d be grateful for further suggestions.

Sorry, [+item[1]+] etc tags can’t be used in Ditto templates, only in document content outside Ditto call.. Here’s how this could be done in current Ditto version..

<?php
$modx->runSnippet("Ditto", array("sortBy"=>"editedon", "sortDir"=>"asc", "displayArchive"=>"0", "summarize"=>"all", "paginate"=>"1"));
$total = $modx->getPlaceholder("total");
$output="";
$count = 0;
for($i=0;$i<$total;$i++) {
   if($count == 0) {
      $output .= "<tr>";
   }
   $output .= "<td>".$modx->getPlaceholder("item[$i]")."</td>";
   if($count == 2 || $i==($total-1)) {
      $output .= "</tr>";
      $count = -1;
   }
   $count++;
}
return $output;
?>

Ditto should get new parameter where you could use some [+item+] and Ditto should do that offset counting.. but until then, I think this is the only way without modifying Ditto..

And it worked indeed, for the website we are developing i’d say it is sufficient. I implemented it last wednessday and it took only minor changes to your code (only the Ditto parameters). Thanks a lot for your help!
