Add new directory structure. Tags will contain current and past releases, and stable will contain any bug fixes to the current stable release so users won't have to get the potentially broken trunk build to fix a screwup in stable.
Trunk updated to 0.9 git-svn-id: http://kusabax.cultnet.net/svn/repo/stable@176 73d99b7e-4f53-4972-b7b7-2ecd3c4d89ee

/**
|
||||
* Similar to the php foreach block, loops over an array
|
||||
*
|
||||
* Note that if you don't provide the item parameter, the key will act as item
|
||||
* <pre>
|
||||
* * from : the array that you want to iterate over
|
||||
* * key : variable name for the key (or for the item if item is not defined)
|
||||
* * item : variable name for each item
|
||||
* * name : foreach name to access it's iterator variables through {$.foreach.name.var} see {@link http://wiki.dwoo.org/index.php/IteratorVariables} for details
|
||||
* </pre>
|
||||
* Example :
|
||||
*
|
||||
* <code>
|
||||
* {foreach $array val}
|
||||
* {$val.something}
|
||||
* {/foreach}
|
||||
* </code>
