Hi - Having put it off for a long time, I've started experimenting with Smarty
(2.6.9) and it's excellent! However, I've been having a bit of difficulty
working out the syntax required in {foreach} and {section} loops to access
multi-dimensional, associative arrays.
The situation:
I'm designing my templates to access values in a series of arrays which detail
document-scope and site-scope properties. The idea is that, using this
method, an array can be built by my application from any (changing) source
(database, xml file etc) without the templates being affected in any way
(i.e. MVC). An example of the document-scope array that I am feeding to the
templates is at the end of this message.
The problem:
I would like to add a sub-array for stylesheets to enable to the loading of
individual stylesheets for specific documents and/or server-side
style-switching. An example of the way I wrote this array was (it's inside
the $doc array) is at the bottom of this message.
However, because there can be more than stylesheet (and the array key is a
unique identifier for each stylesheet), the stylesheet values cannot simply
be accessed using $doc.stylesheets.css.linked.... and so on.
The question:
How do I loop through each of the stylsheets listed in the array
(linked.default, linked.alternate, linked.print, imported.extraRules)
inserting the values for rel, href and so on into the document html for each?
Right at the bottom of the email, I have put my really feeble attempt at doing
this for you everyone to have a laugh at! ;D
Thanks in advance for any help and suggestions,
Chris
