Add this before ajax `console.log($('#signupform').serialize());` — BEingprabhU, Jan 25 '18 at 05:50
Can you post the screenshot of your console in your question?? — BEingprabhU, Jan 25 '18 at 05:55
Open Chrome Dev tools. Click `network` and submit the form, then click the post url in the network tab (should be the last request) and hit `preview` — Alex, Jan 25 '18 at 05:58
Because of the form serializing you are getting an error. I feel so!! — BEingprabhU, Jan 25 '18 at 06:05

Your Javascript Ajax function

      var frmData = $('#signupform').serialize();
      $.ajax({
        type:"post",

        data:{frmData:frmData},
        dataType: "JSON",
        url:"<?php echo base_url('index.php/your_controller_name/your_function_name')?>",       
        success:function(data)
         {

          }
        });

Your controller function

   public function add()
   {
        $postData=array();
        parse_str($this->input->post('frmData'),$postData);

        //prepare post data
        $postData = array(
            'username' => $postData['username'],
            'password' => $postData['password'],
            'email' => $postData['email'],
            'mobileno' => $postData['mobileno'],
            'address' => $postData['address']
        );       
   }

When you use serialize in java script then you must retrieve data using parse_str function of php then you will get exact post data from encoded string .

I've never had to use `parse_str` with serialized data from js. — Alex, Jan 25 '18 at 05:56

As you mentioned in error error: jquery.min.js:4 POST http://localhost/managment//index.php/welcome/add you can see worng direction of URL

Whats wrong

http://localhost/managment//index.php/welcome/add  
                          ^^

WHat should I can do for this

Change url:"../welcome/add", to url:"http://localhost/managment/index.php/welcome/add", `

or

var base = <?php echo base_url() ?>
url: base+"index.php/welcome/add"

Make sure

In application/config.php base Url should be http://localhost/managment/
