Add element in post array using php -


I have an $ _POST array and I would like to add a key at the very end.

So what am I doing, 

  array_push ($ _ POST ['ques_15'], '');

This works but I'm getting a warning 

  Warning: array_push () parameter 1 is array, zero given

How can I remove this warning without closing performance errors?

I think you just want to: 

  $ _ POST ['ques_15'] = '';

Add this end to $ _POST array value '' key ques_15

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module!
