programmatically add post & attachment (about 7000 posts)

First you add the posts, then you add the attachments via the postmeta table. Each attachment appears to need two entries in postmeta, one for _wp_attached_file and one for its meta data _wp_attachment_metadata.

i too m stuck in like same thing…..
I am really confused and messed up now a days in solving this up.
I am getting post_title, post_content and other things in $_REQUEST… as well as an image file. I want to save all that as a post in wordpress database. Can u help me up?
here is what m getting on my page…….
<?php
require_once(“wp-config.php”);
$user_ID; //getting it from my function
$post_title = $_REQUEST[‘post_title’];
$post_content = $_REQUEST[‘post_content’];
$post_cat_id = $_REQUEST[‘post_cat_id’]; //category ID of the post
$filename = $_FILES[‘image’][‘name’];

//I got this all in a array

$postarr = array(
‘post_status’ => ‘publish’,
‘post_type’ => ‘post’,
‘post_title’ => $post_title,
‘post_content’ => $post_content,
‘post_author’ => $user_ID,
‘post_category’ => array($category)
);
$post_id = wp_insert_post($postarr);

?>

I dont know what to do next :(. This will get all the things in database as post. but what about attachment and its post meta .??? can anybody help me up?

@n3v3rl0v3 you can add post meta by using
<?php add_post_meta($post_id, $meta_key, $meta_value, $unique); ?>
