AJAX not passing data to CodeIgniter Controller

Question

Greeting StackOverflow! I am trying to pass data to controller using AJAX, but for some reasons it doesn\'t.

Controller:

public function updateSocial         


        

Answer 1

function updateSocial(name){
            var address = $("#" + name).val();
            var key = name +"&&"+ address;
            //alert(key);
            $.ajax({
                type: "GET",
                url: "controller/updatesocial/"+key, 
                dataType: "text",  
                cache:false,
                success: 
                    function(data){
                        alert(data);  //as a debugging message.
                    }

            });
        }

You are sending data using GET method so you have to send it by appending url and your controller will be

public function updateSocial(){
    $key = $this->uri_segment(3);
    if($key != null){
        list($name, $address) = explode("&&", $key);
        $this->db->query("UPDATE social SET address = '" . $address . "' WHERE name = '" . $name . "'");
        echo "Affected rows: " . $this->db->affected_rows();
    }
}
