[PHPTAL] MPTT to recursive macro
Hi Guys,
I have been experimenting with the Modified Pre-Order Tree Traversal
Pattern, my test case code is returning the results as expected however I am
having trouble with the metal macros to present it.
The example I am using has 3 levels (but is potentially unlimited depth due
to the MPTT pattern) and I am trying to port the example from the FAQ
around it, here is an array representation of the returned database object:
Array
(
[0] = Array
(
[CategoryID] = 1
[ParentID] = 0
[CategoryName] = Default Parent
[lt] = 1
[rt] = 14
[tree_depth] = 1
)
[1] = Array
(
[CategoryID] = 8
[ParentID] = 1
[CategoryName] = SysAdmin
[lt] = 2
[rt] = 7
[tree_depth] = 2
)
[2] = Array
(
[CategoryID] = 2
[ParentID] = 8
[CategoryName] = Linux
[lt] = 3
[rt] = 4
[tree_depth] = 3
)
[3] = Array
(
[CategoryID] = 3
[ParentID] = 8
[CategoryName] = Windows
[lt] = 5
[rt] = 6
[tree_depth] = 3
)
[4] = Array
(
[CategoryID] = 5
[ParentID] = 1
[CategoryName] = Code
[lt] = 8
[rt] = 13
[tree_depth] = 2
)
[5] = Array
(
[CategoryID] = 6
[ParentID] = 5
[CategoryName] = PHP
[lt] = 9
[rt] = 10
[tree_depth] = 3
)
[6] = Array
(
[CategoryID] = 7
[ParentID] = 5
[CategoryName] = Perl
[lt] = 11
[rt] = 12
[tree_depth] = 3
)
)
The example which best sums up what I am trying to achieve with the
resultset is:
ul metal:define-macro=output_list tal:condition=list
li tal:repeat=list_item list
${list_item/CategoryName}
tal:block tal:define=list list_item/sublist
metal:use-macro=output_list /
/li
/ul
tal:block metal:use-macro=output_list /
Obviously there is no sublist in the resultset so the example above is
useless for this purpose, I have spent a few hours experimenting with php
operator conditions trying to work around the lack of dimensions in the
array but as yet have had nothing work, so I was wondering if anyone with a
better idea of TAL can throw me some pointers of how I should approach this.
Thanks in advance.
Nick

Thanks Kornel, that's the conclusion I came to, thought it was worth asking though!
