We know that WordPress is currently most popular blogging CMS. With WordPress, you can do many things. There are a lot of plugins that's help you to create your site amazing. Actually, plugins can be called the soul of WordPress.

Use the plugin on your site help to improve your site but remember the uses of additional plugin can slow your site. Moreover, malicious code hidden into many free/Nulled plugins. That's make your site harmful by hacker. Now you say, "I saw many people using this plugin, but nothing happen".

Hmm, you are right. But i know many people whose sites installed the plugin, after a few month there site has been hacked. So, are you stop using the plugin? Definitely not. But which work can be done easily by entering a few line of code, there don't need use any plugins. I used these method to my WordPress theme projects. That's what's i am going into this series.

FTP/cPanel File Manager is the best way to use these code. Because when editing with WordPress (Appearance > Editor > functions.php ) if you do anything wrong then you can't access your site. Paste these code at the end of your theme function.php file before ;?>
If you have an idea about PHP then you can put code whatever you like.

global $wpdb;
$get_post_info = get_post($post_ID);
if ( $get_post_info->post_status == 'publish' && $_POST['original_post_status'] != 'publish' ) {
// Get all of the emails from the database
$wp_user_email = $wpdb->get_results("SELECT DISTINCT user_email FROM $wpdb->users");
// Send emails to each of registered users
foreach ( $wp_user_email as $email ) {
// Email subject
$subject = 'New Posts from Codiblog.Com ';
// Messages:new post url:+ URL
$message = 'View this new post now:' . get_permalink($post_ID);
// Send email
wp_mail($email->user_email, $subject, $message);

add_action('publish_post', 'newPostNotify');

if ($attached_image) {
