How to get current value of answer? was created by sodiumchl
I see some plugins use something like this:
Code:
$dom = new \toolsDomDocument\SmartDOMDocument();
$dom->loadPartialHTML($this->event->get('answers'));
$input=$dom->getElementById("answer{$sgq}");
$currentValue=$input->textContent;

Yet some other uses
Code:
$currentValue = $_SESSION['survey_'.$oEvent->get('surveyId')][$sgq]; // This can not broke : it's set in EM::_validateQuestion

Indeed, in some cases, I get an empty string with the first method but not the second. Why? What's the difference?

When it's happen …

For the 1st must be used in beforeQuestionRender and get it by HTML already produced. Then need to be sure of {$sgq} .
the second can be used at more place.

If 1st is OK for the id (#answer{SGQ}) : it muts giove the same value.
BUT : there are no $input->textContent; for radio checkbox for example … ONLY for text input
