Hi, I am trying to do something like that as well, here is what i got so far:
lets say you have a custom field with the name “field_1” and one with the name “field_2” and you want the field to return the $value as an array:
make sure that you custom field html got some input with name="field_1" and name="field_2" in the function update_value(); of your custom field put something like:
if( $value ) {
//an array to hold your values
$all_values = array();
$all_values['field_1'] = $value['field_1'];
$all_values['field_2'] = $value['field_2'];
return $all_values;
}
the value of your field is now an array like:
`[“value”]=>
array(2) {
[“field_1”]=>
string(4) “one ”
[“field_2”]=>
string(3) “two”
}
