Here is my code so far i create statues field with many values the default is 'underage'and i make cron function (get_age_comp)  if the condition true the statues should be changed to ('getCard')  my challenge now to add these who their status changed to('getCard') to new model table called (' fci_military_states') and from there i can change the status to the 3rd status ('gotCard') and finally when i change the status in the this table the record must deleted automatic and the status change in the first table (fci_student)to ('gotCard').
