Hi,

The XML data receieved was either invalid or not in the correct form for XML-RPC. Turn on debugging to examine the XML data further.

And My server class is mycontroller.php

Code:

class mycontroller extends Controller {

    function mycontroller()
    {
        parent::Controller();
        $this->load->library('xmlrpc');
        $this->load->library('xmlrpcs');
    }

    function index()
    {
        $config['functions']['call'] = array('function' => 'mycontroller.myfunction');
        $config['functions']['call2'] = array('function' => 'mycontroller.myfunction2');
        $this->xmlrpcs->initialize($config);
        $this->xmlrpcs->serve();
    }
    function myfunction($request)
    {
    $this->load->database();
    $parameters = $request->output_parameters();
    $function = $parameters['0'];
    $table = $parameters['1'];
    if ($this->db->get('product'))
    {
        $query=$this->db->get('product');
    foreach ($query->result() as $row)
        {
          $content= $row->Pro_Id;
          $content1= $row->CarName;
        }
    }
    else
    {
    $content = 'failure';
    }
    $response = array(
    array(
    'function' => array($function, 'string'),
    'table' => array($table, 'string'),
    'Pro_Id' => array($content, 'string'),
    'CarName' => array($content1, 'string'),
    ),
    'struct');
    return $this->xmlrpc->send_response($response);
    }
}

Please help me .
Thanks in advance.

Welcome to the CodeIgniter forums!

I'd suggest you do a var_dump on that array, as it appears to be empty.

I also var_dump on the array.
It gives me following message.

string(133) "The XML data receieved was either invalid or not in the correct form for XML-RPC. Turn on debugging to examine the XML data further."

This is my new mycontroller.php

Code:

class mycontroller extends Controller {

    function mycontroller()
    {
        parent::Controller();
        $this->load->library('xmlrpc');
        $this->load->library('xmlrpcs');
    }

    function index()
    {
        $config['functions']['call'] = array('function' => 'mycontroller.myfunction');
        $config['functions']['call2'] = array('function' => 'mycontroller.myfunction2');
        $this->xmlrpcs->initialize($config);
        $this->xmlrpcs->serve();
    }
    function myfunction($request)
    {
    $this->load->database();
    $parameters = $request->output_parameters();
    $function = $parameters['0'];
    $table = $parameters['1'];
    if ($this->db->get('product'))
    {
        $query=$this->db->get('product');
    foreach ($query->result() as $row)
        {
          $content= $row->Pro_Id;
          $content1= $row->CarName;
        }
    }
    else
    {
    $content = 'failure';
    }
    $response = array(
    array(
    'function' => array($function, 'string'),
    'table' => array($table, 'string'),
    'Pro_Id' => array($content, 'string'),
    'CarName' => array($content1, 'string'),
    ),
    'struct');
     var_dump($response);
    return $this->xmlrpc->send_response($response);
    }
}

I am also giving client part.

Code:

class xmlrpc_client extends Controller {

    function xmlrpc_client()
    {
        parent::Controller();
        $this->load->library('xmlrpc');
    }
    function index()
    {
        $server_url = 'http://127.0.0.1/CodeIgniter/index.php/mycontroller';
        $this->load->library('xmlrpc');
        $this->xmlrpc->set_debug(TRUE);
        $this->xmlrpc->server($server_url, 80);
        $this->xmlrpc->method('call');
        $request = array('optimisation','product');
        if ( ! $this->xmlrpc->send_request())
            {
            var_dump($this->xmlrpc->display_error());
            }
            else
            {
            var_dump($this->xmlrpc->display_response());
            }
    }
}

I'm sorry, I don't understand what's going wrong. I can only suggest that you keep var_dump()ing $parameters as you go, as for some reason, it's not be set the way it should be.

Also, I'd suggest changing this:

Code:

if ($this->db->get('product'))
{
    $query=$this->db->get('product');
    foreach ($query->result() as $row)
    {
        $content= $row->Pro_Id;
         $content1= $row->CarName;
    }
}

To this:

Code:

if ($query = $this->db->get('product')) # $query is set in the if statement to save running the query twice.
{
    foreach ($query->result() as $row)
    {
        $content = $row->Pro_Id;
         $content1 = $row->CarName;
    }
}
