I finally got the answer to the problem.
To make this code work:
global $user_ID;
$new_post = array(
'post_title' => 'My New Post',
'post_content' => 'Lorem ipsum dolor sit amet...',
'post_status' => 'publish',
'post_date' => date('Y-m-d H:i:s'),
'post_author' => $user_ID,
'post_type' => 'post',
'post_category' => array(0)
);
$post_id = wp_insert_post($new_post);
we need to make sure that wordpress’ bootstrap has been started… WordPress bootstrap ensures that all wordpress configuration has been loaded into the memory. This includes all the core functions etc.
Coming back to the original problem of “inserting posts programatically”, we need to call wp_insert_post() at the appropriate place after starting the wp bootstrap.
For this create a new php file like www.yourdomain.com/wpinstalldir/autoposts.php
<?php
/**
* Writes new posts into wordpress programatically
*
* @package WordPress
*/
/** Make sure that the WordPress bootstrap has run before continuing. */
require(dirname(__FILE__) . '/wp-load.php');
global $user_ID;
$new_post = array(
'post_title' => 'My New Post',
'post_content' => 'Lorem ipsum dolor sit amet...',
'post_status' => 'publish',
'post_date' => date('Y-m-d H:i:s'),
'post_author' => $user_ID,
'post_type' => 'post',
'post_category' => array(0)
);
$post_id = wp_insert_post($new_post);
?>
Now when you will execute this script at www.yourdomain.com/wpinstalldir/autoposts.php your post will be created. Easy and simple!
Just adding the line require(dirname(__FILE__) . '/wp-load.php'); made all the difference.
