Hi Perch,
This is a great Friday morning puzzler.
I've written a recursive function that can be used on a category section to find the closest parent field with a value:
function getClosestParentWithTrue($section, $field, $recordNum){
//Retrieve the record
$record = mysql_get($section, $recordNum);
if($record){
//If the chosen field has a value
if(@$record[$field]){
return $record;
//If the chosen field doesn't have a value rerun the function
}elseif(@$record['parentNum']){
return getClosestParentWithTrue($section,$field,$record['parentNum']);
}
}
//If nothing else is found return an empty array
return array();
}
$item = getClosestParentWithTrue('animal_category','highlight',12);
showme($item);
So the system will get the record num from the section passed into the function, then if a record exists it will check if the field has a value, if it has it will return the value. If it doesn't have a value, the function will run again but using the records parent record num.
Cheers
