Using add_filter with Combobox?

Hello,

I’m using a combobox to display / filter regions on a real estate website. How can I add a new region to the combobox via my functions.php file? Basically, I want to combine a few towns into a single option.

I’ve used the code below to add options to a normal dropdown in the search but couldn’t get something similar to work for the combobox:

function edit_rent_range($input_object, $sfid) {
	if(($input_object['name']!='_sfm_rent_max')||($input_object['type']!='select'))
	{
		return $input_object;
	}
	
	if(!isset($input_object['options']))
	{
		return $input_object;
	}
	
	//create a new option we want to add
	$new_last_option = new StdClass();
	$new_last_option->value = "3000000";
	$new_last_option->label = "$35,000+";
	
	//add a brand new option to the bottom
	array_push($input_object['options'], $new_last_option);
		
	return $input_object;
}
add_filter('sf_input_object_pre', 'edit_rent_range', 10, 2);

Any help will be appreciated.

The problem would then be how would our plugin process that choice, unless the combined option would also be attached to any posts, in which case it would already be in the options, so all you would need to is remove those towns.

Thanks for the feedback. I was hoping it would be similar manually to choosing four or five towns in the combobox but instead of the user doing that, they click the new option which automatically selects those towns.

Possible?

It is not, I am sorry, unless, as I said, that ‘combined’ value was also in the meta data for each post.

Ok, thanks for the feedback. There are thousands of entries already so not really feasible to sort through all of those to add the combined option.

Ah. As you say, not feasible then. Can I close this thread?
