There are few mistakes in your form

• there is no name attribute on input type text
• id of Hidden element should not be name (leading confusion)
• Hidden field should be inside form tag

i would prefer like this

PHP

<form>
<input type="text" id="email"  name="email"/>
<input type="hidden" id="hidden_email" name="hidden_email"/>
<input type="submit" id="send_btn"  class="button" value="SEND NOW" />
</form>

jQuery

$("form").bind('submit',function(e){
  e.preventDefault();
  var formEmail=$("input[name=email]").val();
  $("input[type=hidden][name=hidden_email]").val(formEmail);     
});

DEMO

$("form").submit(function(e){
e.preventDefault();
$("#name").val("new_hidden_value");
});

$('input#send-btn').click(function(){
  $('input#name').val($('input#name-emails').val());
  return true;
});

$('#send-btn').click(function() {
  $('#name').val($('#name-emails').val());
});

$(document).ready(function() {
    $("#send-btn").click(function(){
        $("#name").val($("#name").val(name-emails)));
    });
});    

Note that the above code will still submit the form afterwards, which I assume is what you want.

$('form').bind('submit',function() {
    $('#name').val($('#name-emails').val())
    alert($('#name-emails').val())
    return false
})

var value = $("#name").val();
$("#name").val(value);
