Ditto’s extender is an opportunity for defining custom placeholders and/ or filters without interfering into snippet’s core code.

Particularly, a custom filter is an interesting thing — it is a callback function that the core code executes on each item in the final dataset.

countDocs extender counts returned documents and sets placeholder with the calculated value.

How to use countDocs

# 1) put countDocs.extender.inc.php file into /assets/snippets/ditto/extenders folder
# 2) call your Ditto as:
[[Ditto? &parents=`3,4,5` &display=`1` ... &extenders=`countDocs` &tpl=`@CODE:[+count+]` ... ]]

In the above example, Ditto counts documents within 3, 4, and 5 containers. Please notice the display parameter set to 1 — placeholders are being attached to each document within the returned dataset while we (most likely) need to obtain this value in one copy.

PHX and countDocs extender
Comment #2 on: 2011-08-03, 18:49
Hi, first of all, great work on this extender.

Ive been using the extender on one of my sites and have recently started using the PHX plugin.

I noticed that when the PHX plugin is active your extender doesnt work.

All I get is: "&tpl either does not contain any placeholders or is an invalid chunk name, code block, or filename. Please check it."

Any chance of help on with this ?

Sorry for huge delay with this response (due to some implementations/experiments on this site I have accidentally turned off notifications on new comments so I noticed your question only today while reviewing database :(

Standalone PHx plugin (that you have started to use) conflicts with Ditto snippet that comes with its own implementation of PHx. I don't remember the essence of this conflict, but this issue has been discussed on MODx forum from time to time.
