Answer 1

Try this..

You can send data to server by data option in ajax and the type which defines. The default type is GET method

Use " data: {name:name,address:address},"

 $.ajax({
                    type: "GET",
                    url: "<?php echo base_url(); ?>controller/updatesocial", 
                    data: {name:name,address:address},
                    dataType: "text",  
                    cache:false,
                    success: 
                        function(data){
                            alert(data);  //as a debugging message.
                        }

                });

It might creating problem with "&&", Try data: encodeURIComponent(key) in ajax.

Answer 3

function updateSocial(name){
            var address = $("#" + name).val();
            var key = name +"&&"+ address;
            //alert(key);
            $.ajax({
                type: "GET",
                url: "<?php echo base_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();
    }
}

Answer 4

As far as I know ,the problem is at you "var key",change it to : var key = "name="+name+"&"+"address="+address;

Answer 5

Replace this line

var key = name +"&&"+ address;

TO-

var key = name +"-"+ address;

Also explode on server with (-), Try it
