SelectInput multiple=True

[ezra.j.rice]

I am attempting to use the multi select input gizmo, but cannot seem to get it to POST multiple selected values.

Gizmo creation code:

multi_select_input = SelectInput(display_text='Multi Selection',
                              name='multi_select',
                              multiple=True,
                              options=[('One', '1'), ('Two', '2')],
                              initial=['2'])

Pulling data from POST request:

if request.POST:

    input_selected = request.POST.get('multi_select', None)

The output of print(input_selected) is '2' when I had selected '1' and '2' prior to submitting.

Any ideas on why the gizmo doesn't send the entire list of selected options?

Try using the getlist() function: request.POST.getlist(“multi_select[]”).

Thanks Dustin! That got me really close to the solution. PHP requires the brackets, but for some reason that gave me an empty list whereas request.POST.getlist("multi_select") gave me the list of selected options.
