So I think I'm pretty close to what I'm heading for. Here's what I'm doing:
my $field_EmailDL = $form_insert_data->get_field( { name => 'EmailDL'} );
$field_EmailDL->options($emailDL_array);
$emailDL_array contains the following:
$VAR1 = [
[
'label',
'mylabel1',
'value',
'myvalue1'
],
[
'label',
'mylabel2',
'value',
'myvalue2'
]
];
Now I realize that setting ->options() will essentially overwrite the
value of the 'EmailDL'. That's fine, I fix that up later.
What I'm trying to do now ( haven't found it in the docs ) is the way
to set one or more of the values in $emailDL_array to be selected.
The docs say:
"Its arguments must be an array-ref of items. Each item may be an
array ref of the form [ $value, $label ] or a hash-ref of the form {
value => $value, label => $label }. Each hash-ref may also have an
attributes key."
Can "selected" be one of those attributes? How would I specify it?
Based on the above, I've tried the following which doesn't work:
{ value => $value, label => $label, attributes => {selected => 'selected'} }
Should I be looking at another function altogether for setting 'selected' items?
Thanks again,
-Bobby
