Question

I'm trying to get values from two different tables and combine to display on json format. The table exp_channel_data contains event and exp_calendar_events contain date and month of event(field start_month and start_day), but the value of start_month and start_day is assigning to every event and displaying. I should show like this.

    // looping through all results
    // products node
    $response["events"] = array();
    while ($row = mysql_fetch_array($result)) {
        // temp user array
