passing data from view to controller with ajax

I'm currently doing an application which uses ajax in getting user inputs from form fields then concatenate it in a string, this works fine but I'm getting a "POST 500 (Internal Server Error")

and cannot pass the data. How do I pass a string from view to controller with ajax and access it in a controller.

Here are my codes:

the script

<script>
 // $(document).ready(function(){
 function saveData(){
 var con =  document.getElementById('tiks').value;
 // var dataString = {'conid':con};
  alert(con);
  var cct = $("input[name=csrf_token_name]").val();

  var base_url = <?php base_url(); ?>;

  $.ajax({
      url: base_url + "welcome/newShortestPath",
      type: "POST",
      data: {'conid':con, 'csrf_token_name':cct},
      success:function(){
        alert("SUCCESS KALUY-I   "+con);
        $('#myForm')[0].reset();
      }
  });
   }

controller

public function newShortestPath(){
    echo "REACHED";
    $var = $this->input->post('conid');
    //$this -> load -> model('edge_model');
    //$this->edge_model->setConstraints();

}

really need your help guys. thanks in advance. :)

UPDATE

Im no longer getting any error by fixing the errors at calling the base_url() function but at the same time I cant fetch the passed data, is there any other way fetching data from post to controller?

Tips:

Tip 1: You can setup all url: 

var url = <?php echo site_url('welcome/newShortestPath'); ?>;

Tip 2: Use site_url() instead base_url(). base_url must be used to resources (img, css, js, etc.) To build URL's use site_url()

you have to echo the base_url and wrap your var with ''

var base_url = '<?php echo base_url(); ?>';

Update

based on the error you are getting which is:

Fatal error: Call to undefined function base_url()

as you mentioned in your comment.

what you have to do is to go to application/config/autoload.php and find 

$autoload['helper'] = array();

then change it to

$autoload['helper'] = array('url');

or manually load the url helper:

$this->load->helper('url');
