This plug-in is very useful for those who need to duplicate or delete fields within a form.

WHAT DOES:

1. You insert the form inside a div (container) that has a specific class eg. (Class = “contenitore_input”)
2. il div con classe “contenitore_input” verrà chiuso in un ulteriore div con un id specifico es:.(id=”contenitore_generale”)
3. the div with class “contenitore_input” will be closed in another div with a specific id eg. (id = “contenitore_generale”)
4. assign a reference attribute to each field to be duplicated eg. &lt input alt=”nome” &gt
   this attribute will be the fixed part of the “NAME” and “ID”, in this case:
   considering the field &lt input alt=”nome” &gt
   will become
   &lt input alt=”nome” name=”nome_ 1 ” id=”nome_ 1 ” &gt
   click on add …
   &lt input alt=”nome” name=”nome_ 2 ” id=”nome_ 2 ” &gt
   etc…
   This allows the page receiving the request to obtain the value of a specific input or simply differentiate between them
   also allows differentiation of the id to act on the elements via JS uniquely

ADVANCED FEATURES :

1. implementation of a sort of validation to the addition of fields:

• class to indicate the binding of a field
• class to indicate that a field must be numeric
• class to indicate that a field must contain an e-mail
• class to indicate that a field must contain a date in the format dd / mm / yyyy

2. callback functions are available after the addition and after removal of fields
3. duplication of all the attributes of duplicate fields for consistency
