<div class="controls">
<input type="text" class="span4" id="inputEmail" name="firstname"  value="<?php echo $row['firstname']; ?>" placeholder="First Name" required>
<input type="hidden" id="inputEmail" name="id" value="<?php echo $get_id;  ?>" placeholder="First Name" required>     

</div>

Answer 1

If you want to make inputEmail a readonly field, you can use

<label class="control-label" for="inputEmail">First Name:</label>
<div class="controls">
<input type="text" class="span4" id="inputEmail" name="firstname"  value="<?php echo $row['firstname']; ?>" placeholder="First Name" required readonly>
<input type="hidden" id="inputEmail" name="id" value="<?php echo $get_id;  ?>" placeholder="First Name" required>  

Note that I've added the readonly at the end of the input tag in line 3.
