wp_insert_post( $post, $wp_error );

This function inserts posts,pages or your custom post type in the database.

This function's first parameter is $post, which type is array. You must set this parameter. This array has many keys, merely you can omit to put in default values. Keys are listed below :

'ID' => If you set this value, that doesn't mean it will create a post with that ID number. But it will update the post with that ID number with the other values specified in this array.
So if you want to insert a new post, this key must be blank or not set.

'post_content' => The content of the post

'post_name' => The name(slug) for your post

'post_title' => The title of your post.

'post_status' => Set this key to your need. Default value is 'Draft'

'post_type' => This key set the value for your post. Default value is 'post'

'post_author' => The user ID number of the author. Default is the current user ID.

'post_parent' => Sets the parent of the new post if any. Default 0.

This keys are main keys.
Other keys which rarely used are : 'menu_order', 'to_ping', 'pinged', 'post_password', 'guid', 'post_content_filtered', 'post_excerpt', 'post_date', 'post_date_gmt', 'comment_status', 'post_category', 'tags_input', 'tax_input', 'page_template'.

Some important notes which you have to remember are :

1. If you set a post_status of 'future' you must specify the post_date in order for WordPress to know when to publish your post.

This function's second parameter is $wp_error. This is optional parameter. This will allow return of WP_Error object on failure if it is set to true.

Example :

// Create post object
$example_post = array(
'post_title' => 'Test post',
'post_content' => 'This is test post.',
'post_status' => 'publish',
'post_author' => 1
);

// Insert the post into the database
wp_insert_post( $example_post );

What is hook??

Hooks are the backbone of WordPress. They enable plugin developers to “ hook ” into
the WordPress workfl ow to change how it works without directly modifying the core
code. This enables users to easily upgrade to newer versions of WordPress without losing
modifi cations.
