Customize Value Postfix

Hi Andrew

Your link went offline so I couldn’t see. I’m guessing you tried something like the following section of code (this adds a prefix / postfix outside the select field itself).

Also, notice the name doesn’t have the brackets _sfm_distance:

function filter_input_object($input_object, $sfid){
	
	if(($input_object['name']!='_sfm_distance')){
		return $input_object;
	}
	
	//add/override prefix & postfix to the field
	$input_object['prefix'] = "Prefix ";
	$input_object['postfix'] = " Postfix";
	
	return $input_object;
}
add_filter('sf_input_object_pre', 'filter_input_object', 10, 2);

However if you wanted to change the labels (or in this case append text to it) it would be like:

function filter_input_object($input_object, $sfid){
	
	if(($input_object['name']!='_sfm_distance')){
		return $input_object;
	}
	
	//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 we know there are options we can loop through each one, and change what we need
	foreach($input_object['options'] as $option){
		$option->label .= " miles";
	}
	
	return $input_object;
}
add_filter('sf_input_object_pre', 'filter_input_object', 10, 2);

Thanks

PS – I’ve actaully tested both of these just now with my own field, so there shouldn’t be syntax errors.

Thank you Ross. This works great except it also adds it to the ‘Change All Items’ label. So it’s displaying as:

Distance miles
5 – 15 miles
15 – 25 miles

whereas I just want:

Distance
5 – 15 miles
15 – 25 miles

Would that be possible?.

Ah sure, then change the foreach loop to:

	//now we know there are options we can loop through each one, and change what we need
	foreach($input_object['options'] as $option){
		
		if($option->value!=''){
			$option->label .= " miles";
		}
	}
