Custom WordPress Plugin Update from Remote Server

How to simply set up a remote update of the WordPress plugin from your hosting?

This is not difficult .

1 Step – we will use Update Checker Library for this.

We have the Puc folder and plugin-update-checker.php. plugin-update-checker.php must be include into our WordPress plugin file.

/*
Plugin Update
*/
require 'plugin-update-checker.php';
$myUpdateChecker = Puc_v4_Factory::buildUpdateChecker(
	'//yourlink/testwp/maxtestplugin.json',
	__FILE__, //Full path to the main plugin file or functions.php.
	'maxtest-plugin'
);

Finished test plugin file. Add reference to the json file, and the name of the plugin.

<?php
/**
 * Plugin Name: Maxtest Plugin

 * Plugin URI:  maximumtheme.net
 * Version:     1.0.0
 * Author:      maxtestplugin

$myUpdateChecker = Puc_v4_Factory::buildUpdateChecker(
	'//yourlink/testwp/maxtestplugin.json',
