Hi Keith

We have a filter here for modifying all input fields:
https://gist.github.com/rmorse/7b59b45a14b1ca179868

Essentially, the only part you need from that is you need to loop through the options:

function remove_empty_options($input_object, $sfid ) {

	//ensure we are only filtering the correct field name - in this case the field we want to filter has the name <code>_sfm_attorneys</code>
	if(($input_object['name']!='_sfm_attorneys')){
		return $input_object;
	}
	
	if(!isset($input_object['options'])) {
		return $input_object;
	}
	$new_options = array();
	foreach($input_object['options'] as $option) {
		if ( trim( $option->label ) !== '' ) {
			array_push( $new_options, $option );
		}
	}
	$input_object['options'] = $new_options;
	return $input_object;
}
add_filter('sf_input_object_pre', 'remove_empty_options', 10, 2);

I haven’t actually tested this, but it looks to be correct.

You will need some PHP development skills to modify – that should go in your child themes functions.php.

Ross,

Thank you! This works perfectly.

How would I edit it to make the filter work on multiple fields? I’d want to apply it for the following fields:

_sfm_practice_areas, _sfm_industries and _sfm_attorneys

Hey Keith

So you would change:

if(($input_object['name']!='_sfm_attorneys')){
	return $input_object;
}

to:

$allowed_fields = array( '_sfm_practice_areas', '_sfm_industries', '_sfm_attorneys' );

if ( ! in_array( ($input_object['name'], $allowed_fields ) ) {
	return $input_object;
}

Thanks
