How do I read element attribute from $form_state?
0
I set a data attribute on my autocomplete element using jquery like this $(event.target).attr('real-value','6');
How do I get this value from my $formstate or $form object in my form submit function? Using dpm $form[‘elementname’] doesn’t even show this atrribute.
I’ve tried formstate->getValue()
. Doesn’t work?
