Solution

  • Is it possible to create two input box with same name?

    Yes. Element ids must be unique, but names do not.

    Is there any problem while the form is submitted?

    PHP will discard all but the last one unless the name ends in [].

    <input name="foo[]">
<input name="foo[]">

    will be accessible via

    $_POST['foo'] # an array
