Dropdown - value of foreign key [message #2621]

Hello,

I have imported a database in which:
- table SISTEME has primary key cod_sistem
and
- table ANSAMBLE has primary key cod_ansamblu and a foreign key cod_sistem

I related the tables within the framework: parent is SISTEME and child is ANSAMBLE related through cod_sistem.

I then changed the column cod_sistem in ANSAMBLE to be DROPDOWN and I was expecting when adding a new record to ANSAMBLE to have the DROPDOWN cod_sistem of this table populated with the values from SISTEME. This does not happen ... I get a DROPDOWN which is not populated....

I always exported to PHP and I noticed that the ansamble.class.inc for ANSAMBLE is very basic (see the file uploaded) if compared with the one from CLASSROOM eg crs_student.class.inc. What I get inside the class is just a function ansamble, but not others as _cm_formatData, _cm_getExtraData etc. I read #298 and #490 threads, but did not succeed to solve it...

Thanks!
Dan

Telling the framework that you want a field displayed as a dropdown (or radiogroup) is only half of the equation - you must also provide the framework with the entries to populate the dropdown or radiogroup. See How to incorporate dropdown lists or radio groups for details.

You might also want to take a look at:
