Question

In my registration form I have a field called s_id. when i will input the s_id a field name s_name will be filled automatically. actually s_id is id of a old user and s_name is his name. So they are in database like id and name being used as s_id and s_name for a new user.

Here is my view code

<input type="text" name="s_id" id="s_id" onkeyup="get_user_name('id');" />
<input type="text" name="s_name" id="s_name" />

<script type="text/javascript">
    function get_user_name(id){
        var data = $('#'+id).val();
           jQuery.ajax({
              url: "<?php echo site_url('welcome/test');?>",
              type: "POST",
              data: { id:Data },
              cache: false,
              dataType: "text",
              success: function(data) {

            $("#name").val(data);            

            }
        });

    }

    </script>

What should be the controller and model function structure for this job?

Answer 1

In controller: You just need to echo the result.

Like this:

function temp()
{
   $uname=$this->name_of_model->get_username($_POST[['id']);
   foreach($uname->result() as $r)
   {
      echo $r;
   }
}
