[PHPTAL] access previous / next item in array?

2009-09-18 Thread GRolf 


I'm doing a

div tal:repeat=item items

Previous id: ???
Current id: ${item/id}
Next id: ???

/div



Is there any way to add a callback function that will be called on
each repeat, so I could easily put the next and previous id ?

I could loop through the array in PHP, before assigning to PHPTal
object, and set them. But that would mean looping through the array
twice (once before, once for output)...

If array is numerically indexed, then this will work:

tal:define=prev items/${php:repeat.item.index - 1}/id | nothing; next  
items/${php:repeat.item.index + 1}/id | nothing



RepeatController reads one item ahead and could store previous item, so if  
you're willing to change PHPTAL's code, it's possible to easily add  
something like repeat.item.next/repeat.item.prev.

[PHPTAL] ajax and phptal

2009-09-18 Thread hosemaria 
Hi 

I am working on ajax php website. Ajax makes using phptal more complicated.

My approach is to divide single page to several php files and every time at
single page i create new object of $tpl. It means that I have to use several
$tpl-execute() at the first page load. I think it is not optimal.

My question is whether there is most efective way to use phptal and ajax?

page.xhtml:

body
stuff
tal:block metal:use-macro=widget.xhtml/show_widget /
stuff
/body


widget.xhtml:

div metal:define-macro=show_widget
ajax me!
/div
tal:block metal:use-macro=show_widget /


This will let you either execute page.xhtml with all stuff in it, or  
execute widget.xhtml and just output that single fragment. You can use  
variables in use-macro (e.g. show_${name}), so you're not limited to  
one thing per file.
