Determine if CodeIgniter’s Model Save() is Insert or Update

I have been playing with this functionality.

If I use

PHP Code:

$this->getInsertID() 


instead of

PHP Code:

insertID() 


CI does not throw an error.

I've checked the DB and all seems in order.

Therefore it looks like I can use the save() function to insert and update, and return the insert id when an insert is performed.

PHP Code:

public function addEditData($vals) {
        if($this->save($vals)) {
            log_message('notice', '[SUCCESS] {file}-{line}, Data Saved - '.session('user_name'));
            
            if($insertID=$this->getInsertID()) {
                return $insertedID;
            }else{
                return true;
            }
            
        }else{
            log_message('notice', '[ERROR] {file}-{line}, Failed to Add/Edit Data - '.session('user_name'));
            return false;
        }
    }
