Hi Javier
You can do this with the current version..
Take a look at the docs here:
https://www.designsandcode.com/documentation/search-filter-pro/action-filter-reference/#Filter_Input_Object
Nearly any value in any input object can be changed if you dig deep enough into the $input_object there are all kinds of things that can be changed.
Tested locally, and updated to match your field name _sfm_precio, this should do the trick:
function filter_range_dropdown($input_object, $sfid)
{
if($input_object['name']=='_sfm_precio')
{
//udpate this field before rendering
//if we want to filter the options generated, we need to make sure the options variable actually exists before proceeding (its only available to certain field types)
if(!isset($input_object['options']))
{
return $input_object;
}
//now loop through the options in the field
foreach($input_object['options'] as $option)
{
//update every label, and prefix and suffix with $
$option->label = "$ ".$option->label." $";
}
}
//always return the input object, even if we made no changes
return $input_object;
}
add_filter('sf_input_object_pre', 'filter_range_dropdown', 10, 2);
Hope that helps
