Select2 - saving ID and Text in two database fields
Select2 - saving ID and Text in two database fields

Hello,
I’m currently in the process of including select2 in the editor and can’t continue at one point.
Basically loading and saving works through the ID and Ajax via fn.dataTable.Editor.
However, besides the ID, I also have to save the content / text in an separate field of the database.
Is there a solution?

Yes - use
dependent()on your Select2 field to set the label of the selected value as ahiddenfield.dependent()will run whenever the Select2 value changes, so they two will always be in sync.Allan
p.s. Would a join not be a better option for this?
Hello Allan,
thanks for the quick reply and the helpful hint.
I think I'm on the right path (or miles away ;-)).
My current attempt:
editor.dependent( 'MyFieldWhitSelect2', function ( val, data ) {
if (val == null || val == ""){
} else {
var Text = editor.field('MyFieldWhitSelect2');
editor.field('MyHiddenTextField').val( Text.? );
}
});
How can I read the text of Select2 in the editor?
PS: Inner Join is for a variety of reasons probably more a problem (free text input must also be possible).
That looks about right. In the [Select2 documentation
(https://select2.org/programmatic-control/retrieving-selections#using-a-jquery-selector) you would use something like:
Use
field().input()to get thehtmlelement for the field.Allan
Hello allan,
many many thanks!
I could finally implement with your help a very good solution.
Another problem has now emerged.
If an entry of select2 contains a very long text and this is selected, the edit-window is widened across the screen width and the user can’t save anymore.
I still need help regarding the problem with the window width.
What is the event that trigger the window width when selecting an item in select?
Select2 has a
widthoption which would seem to be ideal here. Set it to beelementperhaps.Allan
Thanks for the feedback. I could solve it by another, very special way (no return of the selected text).
