Re: [PHPTAL] Need some help with a loop

[Iván -DrSlump- Montes]

Hi,

This is one of the cases where TAL is a bit strange to work with. The
following should work even if the HTML generated is not standards compliant.

<tal:block repeat="image images">
  <tal:block tal:replace="structure '&lt;tr&gt;'"
tal:condition="php:repeat.image.index % 5 == 0" />
  <td>
    <img src="${image/src}" />
  </td>
</tal:block>

Another option (better in my opinion) would be to split the list in chunks:

<tr tal:repeat="chunk php:array_chunk(images, 5)">
  <td tal:repeat="image chunk">
    <img src="${image/src}" />
  </td>
</tr>

ciao,
/imv
