Change small features and fix save problem in PHP app

I've a PHP app that I've to fix and complete save/update process Manager user permission (I'll send details for manage admin flag) Make select fields (in forms) and filter fields (in [login to view URL] page) with border style as in other forms Check Delete; show a confirmation modal popup and don't open new page (I remeber that delete doesnt' delete an events but set [login to view URL] to 1) In edit mode of each event don't allow to change Date/State/City/Town/Address/<wbr />Cap value ... allow only when insert new event, but not when update already created events In Utenti table we have a field named [login to view URL], when you create or update Events you've to save this value (for the logged in user) in [login to view URL] Check Save/Update process for events and locations (but I think that these are OK) Title, Address, City, State, Town, Date are required Fields All select fields in each event form must be filled! (and in edit mode, filled with selected value of the selected record) I need code day by day
