I tried above and other links related to my problem. But not get any solution.
Environment
- OS : Windows 7 - 64 bit
- Framework : CodeIgniter PHP MVC
- Client side: Javascript - Jquery
- Server side: NodeJS
- Database : MySQL
I need to make a http post call from server(Node + express)(server.js) to Codeigniter controller file.
I am using Jquery Ajax to make a post call in Node server.js file. But post call not working in client end.
Code Samples:
Controller - Welcome.php
<?php
Class Welcome extends CI_Controller {
public function __construct(){
parent::__construct();
$this->load->helper('url');
}
public function index(){
$this->load->view('welcome_view');
}
function testFunction(){
$getData = $this->input->post('sendData');
$rec_data = $this->Welcome_model->testFunction($getData);
echo json_encode($rec_data);
}
}
Model - Welcome_model.php
<?php
Class Welcome_model extends CI_Model
{
public function __construct(){
parent::__construct();
$this->load->helper(array('form','url'));
$this->load->database();
}
function testFunction($getData){
$this->db->query("INSERT INTO test_tbl(test) VALUES('$getData')");
if($this->db->affected_rows()>0){
$this->db->close();
return 'true';
}
else{
$this->db->close();
return 'false';
}
}
}
view -> welcome_view.php
<!DOCTYPE html>
<html lang="en">
<head>
<title>view file</title>
</head>
<body>
<div class="container">
<button id="btn-id">Click me</button>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
var socket_link = "socket_link";
var socket = io.connect(socket_link);
$(document).on('click','#btn-id',function(e){
var testData = "12345";
socket.emit('send_data', testData);
});
</script>
</body>
</html>
Node file -> server.js
var socket = require('socket.io');
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = socket.listen( server );
var port = process.env.PORT || 3000;
var $;
require("jsdom/lib/old-api").env("", function(err, window) {
if(err){
console.error(err);
return;
}
$ = require("jquery")(window);
});
server.listen(port, function(){
console.log('Server listening at port %d', port);
});
io.on('connection', function (socket){
socket.on('send_data', function(data)
{
console.log("test line: "+data);
$.ajax({
type: "POST",
url: "http://ip:port/welcome/testFunction",
data: "sendData="+data,
dataType: "text",
cache : false,
success: function(getData){
var parseData = $.parseJSON(getData);
console.log("parseData: "+parseData);
}
});
});
});
Node server started in my project. Server listening the port. Onclick button in view, socket will emit in view and socket will receive the data in server.js file.
I need ajax post call i need to done in server.js, which will call controller-> model-> data will be inserted into database.
Need an return value in view through server.js file.
How to check post call in browser..? How to achieve this.?
