hi all, i have 3 tables (tl_subject,tl_playlist and tl_playlistitem) representing three levels ...parent, child and child's child.
When i edit a playlistitem the "Go back" link returns me to the subject (first level) rather than the playlist (second level).
The link has an href of "do=ModuleName".
I assume it needs to say "do=ModuleName&table=tl_playlist"

Where can i change this to refer back to the middle table (list)?

i have never tried, never seen and i don't know if its even possible to make a 3-child relationship with TL like you have, but I guess its possible.

perhaps you have setup your DCA incorrectly. this has happened to me many times. check examples like Newsletter or News, which uses the parent child relationship.

cheers thyon, but i can't find anything similar.
i figure it should be something to do with href in the global operations, but i don't see how to apply it to the go back link (it seems controlled from elsewhere?).
The 3 level arrangement works fine for me otherwise.... the good thing about not knowing what you're doing is that you don't know that you can't do it!!

I've seen this too. It only appears/happens when you have parent-child-child (type1-type4-type4) relations...

yes andreas, thats exactly how its set up. It just affects returns to the middle table.
Is this a bug?
Or is there something i can do to force the goback link to say "do=ModuleName&table=tl_playlist"

I use it like this - I think it's a bug

Please check against the latest version (2.6beta2). It includes a fix if I remember correctly.

thanks leo, i'll test it

Leo, it does exactly the same in 2.6 beta2.
Any idea how I can override it?

Very nice new version by the way... it installed easily, no problems at all yet... those "save and new" buttons are a treat! I'll play around more with it soon.

It doesn't for me Leo, nor in 2.6.0 or 2.6.1
Could you tell me where the code is that creates these buttons so i can have a go at solving this?
I can't figure where the buttons are generated from.

The Back button is being generated in DC_* drivers. Usually that would be system/drivers/DC_Table.php.
So the trick is to add '&ptable=parent_table&pid=pid' to the edit (or whatever) button link of the child row and modify DC_Table.php to account for that (see the attached patch). Where parent_table and pid refer to a parent table we would like to get back to.

I have tested that trick on 3 tables (parent->child->child), but apparently any number of nested tables will do just fine.

thanks very much vu1tur, i'll check this out.

just in case you missed this in the other post, but I forgot that the News Module does a 3-level parent-child-child, using below, so its worth a look.

tl_news_archive => tl_news => tl_news_comments

Thanks Thyon...
i've been a bit sidetracked recently but i'll take a look soon at yours and vu1tur's suggestions.

Hi,
vu1tur thanks, but i need to solve this without modifying any system files.
That was a great help to see whats happening....

Within $return (in the DC_Table.php),

Code:

$this->Input->('id')

returns a value ok, but

Code:

$this->Input->('pid')and $this->Input->('ptable')

do not return anything,
so the back button just points to the module startpage (?do=MyModule).
Thats the source of this problem

Thyon, the news module doesn't seem be modified anywhere to counter this that i can see.... although it is three-tiered it isn't of the sorting type (type1-type4-type4) like mine, but rather 1:4:2 so it may not affect it.

Andreas suggested it is a bug affecting only 1:4:4 sorting types, Leo said he "thought he fixed it", then ignored me when i said it wasn't, and vu1tur says you can modify DC_Table to get round it. So to me it sounds like a big bug.

Its beyond me. I would have had two modules released two months ago if it wasn't for two faults... this and a problem with the "save and edit button" also misdirecting when you go from the second table to the third.

Does anyone know how i can simply make the "saveNedit" button and the "goback" button not show from commands in the DCA?
Cheers, Murray.
