Extenders for Custom Placeholders

Got it figured out, thanks to help from the guys on the MODx irc channel. Here’s the HOWTO on the Wiki.

No. err.... no execute Parser call in manager/index.php??

I meant add that to the index.php, not manager/index.php

Not sure if the $resource is needed

It is needed as the function must accept one value (the resource array) whether you utilize it or not.


It might be better (and faster) to use a field that has already been retrieved, like id, in place of the *.

@Susan: Thank you!

I am still totally lost as to what all the parameters mean.



the $placeholders[’example’] part I get, that will be the name of the placeholder, and the "exampleFunction" is the name of the function you’ll write to set that placeholder’s value. It’s all the rest that is over my head.

I just blindly used Heliotrope’s code and it worked once I got the $GLOBALS[’ditto_lang’] bit figured out from reading the ditto source, but I have no idea what that "*" is for.



This extender business is a very powerful resource!

If I understand mark answer, the => * means all field from the $resource array.

:-)

Hmm. So a print_r($resource) might prove beneficial...

Array
(
    [introtext] => we are pleased to announce blah blah...
    [id] => 366
    [published] => 1
    [pagetitle] => our fantastic announcement
    [createdon] => 1193124818
)

Then what is that inner array, array("pagetitle","*") doing?

In

the * means in both the frontend (visible result) and the backend (for filtering).

It might be better (and faster) to use a field that has already been retrieved, like id, in place of the *.

I mentioned this because Ditto would will try to process a non existent (the asterisk itself) field if * is the only thing in the first position of the array.
