I am using this code to auto create a page when I activate my plugin..
function insert_page(){
// Create post object
$my_post = array(
'post_title' => 'My post',
'post_content' => 'This is my post.',
'post_status' => 'publish',
'post_author' => get_current_user_id(),
'post_type' => 'page',
);
// Insert the post into the database
wp_insert_post( $my_post, '' );
}
add_action('init', 'insert_page');
The issue now is whenever it loads the admin page it creates also a new page.. is there any way that it only auto create 1 page? when the plugin activate only it then create only 1 page?
also I have on my mind that when it created at wp_insert_post( $my_post, '' ) how can I get the post/page ID? so that I an determine if the page were already exist or not...

Hope this will help you.
These code is working fine with new WordPress.
Add this code in the file after activating this plugin the page will auto crated.
register_activation_hook( __FILE__, 'myplugin_activate' );
function myplugin_activate() {
//create a variable to specify the details of page
$post = array(
'post_content' => 'content', //content of page
'post_title' =>'Choose-plan', //title of page
'post_status' => 'publish' , //status of page - publish or draft
'post_type' => 'page' // type of post
);
wp_insert_post( $post ); // creates page
}
wp_insert_post()returns post id. Codex is your friend. Alsoinitisn't the right hook. seeregister_activation_hook. – Sisir Commented Apr 13, 2015 at 4:12
