There are three fields:
поле1 поле2 поле3 поле4 Добавить поле (кнопка) Скопировать (кнопка)
field1 - data (info)
field2 is a date (just a date, for example, in the format 02/19/2015 and not in any way)
field3 - how many times you need to repeat the field!
field4 - how many days
Add field - when you click on this button, nothing is copied, just dynamically all fields are added to the form ( field1 , field2 , field3 , field4 and copy button).
Copy - when you click copy, the field 3 and field 4 fields are checked, and the field field 1 and field 2 are copied down below the field .
Another button Delete - deletes 1 element and all child (copied) elements of this field ...
And just as it is a miracle, then consider the post request?
So far, I could make (more precisely, remake myself) the dynamic addition of fields.
