Rgpost not getting field value [RESOLVED]

add_filter( 'gform_pre_submission_18', 'time_calculation' );
function time_calculation($form){
	$getvalue = rgpost("input_18_5_1");
	if (!empty($getvalue)){
		echo $getvalue;}
	else echo ("no value");

I am trying to do time calculation when user hits submit, but before an entry is made. Following guides and documentations online, rgpost() is what I am looking for. But it did not return the field value, the above snippet echos no value.

The field value I try to grab is the Time Widget in 12 hour format, input_18_5_1 is the hour input.

I have tried to use the number widget’s calculation function, but the duration did not show up in real time as user make changes.

Rather than using echo for debugging, I would recommend you to enable logging.

That would allow you to add custom logging statements to your code. For example to dump the full contents of $_POST to the log to confirm if there’s really a value for that input or something wrong with rgpost:

GFCommon::log_debug( __METHOD__ . '(): $_POST content => ' . print_r( $_POST, true ) );

Per your instructions Sam, the core log file did not have an item for this debug call. Then do we assume, rgpost() is not working properly?

Hello. I am not sure why your logging is not working. rgpost is definitely still working, and gform_pre_submission is still working.

The time values are submitted as an array for the field, so you can’t use rgpost alone. Try like this:

// form 18 only
add_filter( 'gform_pre_submission_18', 'time_calculation' );
function time_calculation( $form ){
	// time field is ID 5
	$time = rgpost("input_5");
	$hour = $time[0];
	$min  = $time[1];
	$ampm = $time[2];
	if (!empty($hour)){
		GFCommon::log_debug( __METHOD__ . "(): Hour is {$hour}." );
	else {
		GFCommon::log_debug( __METHOD__ . "(): Hour is not set." );

Thank you so much Chris! With this method, I was able to review the data in logging.
I believe the fix is you have defaulted input_5 for time field. I was using the ID from inspect element instead of name, will take note for future uses.
