How To Create custom plugin field for flexi content

hi,
I'm new to FLEXIcontent for joomla 2.5. and I have a little problem.

In fact, I would like to know where to find a tutorial for creating plugin FLEXIcontent.
to be precise, I would like to create a version of the plugin "relation", but, I want that in the front end, the filed showns only items posted by the current user.

For example, I have a category called FLEXI with contennant articles posted by user1, user2 and user3. I want if user1 logs in and accesses the submission form item that the field "relation" only shows items sent by User1.

Thank you for your help, I hope I'm clear enough.
Sorry for my bad English "googletrad!"!

Hello,

It is better to avoid duplicating an existing field for minor changes, since you will be missing new features

what you ask can be done without duplciating the field type, but if want to duplicate the field type then please see this FAQ article for duplicating an exist field type:

How to Duplicate a Flexicontent Field to create a new Field Type

-- After creating a new custom field type "myrelation", then edit your existing field e.g. field15 and set it's type to be of field type "myrelation" instead of "relation"

NOTE: about custom coding on the new field type, this will require time on your part
[/list]

OK, I could not have imagined such a quick response. thank you.
since I'm new, and before I started the creation of a field "myrelation" (which will take me much longer I guess)
How can I do so without creating new field, with the current plugin "relation"?

Hello,
this is interesting/useful and is trivial to add

-- you can download latest version of relation field from here:
code.google.com/p/flexicontent/s ... 2Frelation

Click on each file, then click view "raw file" and save it on disk)
files:
en-GB.plg_flexicontent_fields_relation.ini
relation.php
relation.xml

if i don't make a mistake, i should modify this in relation.php line 215


$query = "SELECT i.title, i.id, i.catid, i.state, GROUP_CONCAT(rel.catid SEPARATOR ',') as catlist, i.alias FROM #__content AS i "
. (($samelangonly || $method_types>1) ? " LEFT JOIN #__flexicontent_items_ext AS ie on i.id=ie.item_id " : "")
. ' LEFT JOIN #__flexicontent_cats_item_relations AS rel on i.id=rel.itemid '
. ' LEFT JOIN #__users AS u ON u.id = i.created_by'
. $where
. " GROUP BY rel.itemid "
. $orderby
;

but i don't know how ton continue

Hello,
