Making Coding Modifications To Website -- 2

Need some to do some minor coding. At present the system queries a marketplace to activate, verify the license, I want to add additional code to verify license that are bought on the website. I need someone to add the code that will. The code you are working in written in codeigniter framework, but you will have to access a database located in a wordpress database. 1) Check the following table postmeta for the license key. This is in the wordpress database. If there is no key then it will say invalid. If there is a key it will try to insert the key into the database connect. This database is not part of the wordpress database 2) If there is a key in the database connect it will say “This license key is currently activated on another site” 3) If there is no key in the database connect, it will insert the key into database “connect”. There might be other changes that have to be made. Also you should backup all files before you make changes. I have attached [login to view URL] (the code is shown below. [login to view URL] code that will be useful into making queries into postmeta table Budget $50.00 <?php defined('BASEPATH') OR exit('No direct script access allowed'); class Main extends CI_Controller { protected $package_dir = '../ci-folder/product-packages/'; function __construct() { parent::__construct(); $this->load->model('license_mdl'); $this->load->helper('download'); } public function index() { redirect('[login to view URL]'); } public function license_verify( $key ) { $this->load->database(); $verify = $this->envato_purchase( $key ); // Verify Envato purchase code if ($verify) { // Check DB for the key $used = $this->license_mdl->where( 'code', $key )->get(); if ($used) { $result = array( 'status' => FALSE, 'message' => "This license key is currently activated on another site." ); } else { // Saved key to the DB and return true $this->license_mdl->insert( array('code' => $key) ); $result = array( 'status' => TRUE, 'message' => "Valid License Key" ); } } else { $result = array( 'status' => FALSE, 'message' => "This license key is invalid." ); } // Return json result $this->output ->set_content_type('application/json') ->set_output(json_encode( $result )); } public function license_deactivate( $key ) { $this->load->database(); // Get the Code ID $activated = $this->license_mdl->where( 'code', $key )->get(); // Delete the Code $this->license_mdl->delete( $activated['id'] ); // Return json result $result = array( 'status' => TRUE ); $this->output ->set_content_type('application/json') ->set_output(json_encode( $result )); } public function download_woomobify( $key ) { // Verify license and download file $file_name = "" . $this->package_dir .
