[PHPTAL] true:

[Levi Stanley]

Interesting discussion.  So basically if I wanted to do something using 
true: I would do something like this:

<table id='dynamic_stats_table'>
<!-- Title bar of dynamic stats table -->
<tr>
   <td tal:repeat="stats_column stats_title" tal:condition="true: 
stats_column/hasAccessToView" tal:content="stats_content/getTitle"/>
</tr>
<!-- Now show the data -->
<tr tal:repeat="stats_row stats_info">
   <td tal:repeat="stats_column stats" tal:condition="true: 
stats_column/hasAccessToView" 
tal:content="stats_row/getData/${stats_content/getTitle}"/>
</tr>
</table>

Actually, was looking for something like that, ended up using a php: 
which I know I will have to fix later if I were going to go to Petal, or 
some other TAL implementation.  Is there another way to do this without 
using php_tales, php: or true:  Just interested in knowing.

Best regards,
Levi
