I am developing an addon for EE. i could not find a way to make a variable with multi value behavior. like: i would like to write in the template: {location:lat} {location:lng} this can be (Pair Variables) but it is always about loops.
what is the proper and the write Array syntax to parse to get what i want in the template.
thank you in advance
The only add-ons which have an official method of using variable modifiers are fieldtypes, where your fieldtype class' replace_tag function controls {my_field}, replace_lat controls {myfield:lat}, etc.
If you want to use the modifier sytax in a plugin or module, you'd simply name your variables location:lat and location:lng in the array you pass to ee()->TMPL->parse_variables().
The standard way of accessing nested variables like this, given a variables array that looks like:
array(
array(
'location' => array(
'lat' => 'foo',
'lng' => 'bar'
)
)
);
... would be:
{location}
{lat}
{lng}
{/location}
$json['location'] = array( array('lat'=>$json['location']['lat'],'lng'=>$json['location']['lng']) );
