Forgot -- Re: [PHPTAL] How do you print a grid with tal:repeat ?

Tue Feb 20 02:36:33 CET 2007

A while ago i posted a patch to PHPTAL to enable the use of tal:while,
and later added also tal:dowhile but didn't post the patch.

Here is one use of this to display a grid of 3 columns wide and as many
rows as required.

<table>
  <tal:block tal:while="php: next(items)">
  <tr>
    <td tal:define="item php:current(items)">
      <div tal:condition="item" tal:content="item">Default Text</div>
    </td>
    <td tal:define="item php:next(items)">
      <div tal:condition="item" tal:content="item">Default Text</div>
    </td>
    <td tal:define="item php:next(items)">
      <div tal:condition="item" tal:content="item">Default Text</div>
    </td>
  </tr>
</table>

Adding / removing columns can be done just by duplicating the cell code,
or the code could be rearranged slightly to allow a dynamic amount of
columns.

The use of a macro could help to define and contain the logic of what
the contents of each cell looks like if there is something to display,
or generic content if there is not.
