I need to edit 4 fields in a form as describe below :
id_level2 depending of the value of id_level1,id_level3 depending of the value of id_level2,id_level4 depending of the value of id_level3

in other words, i would like to select the child of his parent, and this 3 times in the same form

extract from fieds.ini :

[id_level1]
widget:label=”level1”
widget:type = select
vocabulary = listelevel1

[id_level2]
widget:label=”level2”
widget:type = lookup
widget:filters:id_parent_level=$id_level1

[id_level3]
widget:label=”level3”
widget:type = lookup
widget:filters:id_parent_level=$id_level2

[id_level4]
widget:label=”level4”
widget:type = lookup
widget:filters:id_parent_level=$id_level3

but it doesn’t work !

how can i do this ?

thanks for your help

Unfortunately filters are currently very limited, static, and handled server-side so you can’t currently do it this way. This is currently kind of a tricky thing to do. You would need to use some custom javascript.

I recall at least 3 or 4 threads in the forum where people discuss this and there are a few different solutions. All require some custom javascript right now.

Actually, I like the syntax you used in your fields.ini file for this. As it wasn’t hard to add support for this in the lookup widget, I have made some changes in SVN to support what you were trying to do.

You would need to update the files
HTML/QuickForm/lookup.php
js/RecordBrowser/RecordBrowser.js

from SVN
