make new folder in plugin after whatever you want your folder name, remember that file name and folder name same .
make folder in this folder wp-content/plugins/

viral is your plugin folder and viral.php is your plugin file
now add code in viral.php file.
viral.php
<?php
/**

add_action('admin_menu','viral_menu');
function viral_menu(){
add_menu_page(
'viral', // page title
'viral', // menu title
'manage_options', // by-default admin site
'dashboard', // this is called page slug
'my_function',// callback function which we called
'dashicons-dashboard', // this is our icon
6 // this is our plugin position
);
//we have only one sub menu then why its showing 2?
//lets make this one
add_submenu_page(
'dashboard', // parent slug beause we need submenu of this menu
'first submenu', // page title
'first submenu', // menu title
'manage_options', // by-default admin site
'dashboard', // menu slug
'my_function' //call function which we click on sub menu and open that page
);
add_submenu_page(
'dashboard', // parent slug beause we need submenu of this menu
'second submenu', // page title
'second submenu', // menu title
'manage_options', // by-default admin site
'second-submenu', // menu slug
'second_submenu' //call function which we click on sub menu and open that page
);
add_submenu_page(
'dashboard', // parent slug beause we need submenu of this menu
'third submenu', // page title
'third submenu', // menu title
'manage_options', // by-default admin site
'third-submenu', // menu slug
'third_submenu' //call function which we click on sub menu and open that page
);
}
//directory
define("PLUGIN_DIR_PATH", PLUGIN_DIR_PATH(__FILE__));
function my_function(){
include_once PLUGIN_DIR_PATH . '/include/first.php';
}
function second_submenu(){
include_once PLUGIN_DIR_PATH . '/include/second.php';
}
function third_submenu(){
include_once PLUGIN_DIR_PATH . '/include/third.php';
}
//now we make table and page automatically when we activat our plugin
require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
register_activation_hook(__FILE__,'table_activate');
register_activation_hook(__FILE__, 'create_page');
//deactivate hook
//drop table when plugindelete
function table_activate(){
global $wpdb;
$sql = "CREATE TABLE `wp_registration` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(30) NOT NULL,
`last_name` varchar(30) NOT NULL,
`email` varchar(30) NOT NULL,
`password` varchar(15) NOT NULL,
`phone_no` bigint(10) NOT NULL,
`reg_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1";
$wpdb->query($sql);
}
// when we click on activate table made automatically when our plugin activate
//now we make our page too
function create_page()
{
$page = array();
$page['post_title'] = "custom page";
$page['post_content'] = "this is our custom page when you active out plugin this page also created with plugin";
$page['post_statud'] = "publish";
$page['post_slug'] = "custom-page";
$page['post_type'] = "page";// this slug make you choice either page or post which is ?
$post_id = wp_insert_post($page);
add_option("custom_plugin_page", $post_id);
}
register_deactivation_hook(__FILE__, 'deactivate');
//in this tutorial we deactivate our plug in and deactivate out table too.
function deactivate(){
global $wpdb;
$sql = "drop table wp_registration";
$wpdb->query($sql);
}
//now we are going to fetch all our post in one page
?>
make another folder in wp-content/plugins/viral
exmaple : wp-content/plugins/viral/include
viral is your plugin folder and include is subfolder of your viral folder
now make another file in inlcude folder name first.php
example : wp-content/plugins/viral/includefirst.php
first.php
<?php
$args = array(
'post_type' => 'post',
'orderby' => 'ID',
'post_status' => 'publish', //we fetch our publish post
'order' => 'DESC',
'post_per_page' => -1 //here how much post you want to show
//if you erite -1 then your all post arwe fetch if you write 2 then your 2 post are fetch
);
$result = new WP_Query($args);
if($result->have_posts()){
while($result->have_posts()){
$result->the_post();
?>
<h1> <?php the_title(); ?></h1>
<?php the_content(); ?>
<?php
}
wp_reset_postdata();
}
else{
echo "oh sorry for that but there have no post yet!";
}
?>
