Selection of first dropdown determines second dropdown

QuestionsSelection of first dropdown determines second dropdown
Rudolf Wagner asked 4 months ago

Hello Abu,

I still need help. I managed to build the grid as desired: During the process of adding a new record, when I select a customer in the first dropdown only the jobs of this customer are shown in the second dropbox. When the input is finished the grid seems ok.

But when I update the browser all job entries disappear. The data in the database is not touched since I use IDs. But nevertheless this is not as expected. I guess I didn’t really understand the correct application of the event triggers. Sorry

Can you have a look into this?

Kind regards,

Here is my code (with focus on line 87-115):

I don’t want to be too pushy, but is there really no one who can help me with this problem? Or is there still a lack of information from my side?

Kind regards,

On line 112, Try adding:

$str = $g->get_dropdown_values("select pk as k, Bezeichnung as v from Auftraege");
$col["editoptions"]["value"] = $str,

To fill the list, you will need all key:value mappings but when you provide an [“onload”][“sql”] query, it limits them to your where condition for edit/add dialog.

Hope it solves your case and apologies for the late reply.
