wp_insert_post() │ WP 1.0.0
Safely inserts/updates a post in the database.
The function sanitizes the input data, performs certain checks, and fills in missing variables (e.g., if the post date is not provided, it will be set automatically).
It expects escaped data. This means that if the function is called with non-POST data, you need to process the data array with the wp_slash() function before passing it.
IMPORTANT! You must specify 'post_author' => user_id if the code is executed outside the context of a logged-in user, for example, via CRON, REST, etc. By default, the function assigns the ID of the current user, and if no user is available, it assigns 0, which can cause various bugs.
Note that various hooks such as save_post and wp_insert_post are triggered by this function. Callback functions for these hooks may rely on $_POST/$_GET data, which may not be available on the frontend. This can lead to errors if the function is used on the frontend—check for issues in the hook callbacks.
Categories
Categories must be passed as an array of numbers matching the category IDs in the database. This applies even if only one category is provided.
See also: wp_set_post_terms()
Security (Post Title Sanitization)
The function processes the input data using sanitize_post() , which validates and sanitizes all fields. Therefore, there's no need to sanitize the data beforehand.
However, you might need to remove HTML tags or other non-standard characters from the post title. WordPress doesn’t do this automatically for titles. Use sanitize_text_field() for this, especially when posts can be submitted from the frontend:
// Create the post data array
$post_data = array(
'post_title' => sanitize_text_field( $_POST['post_title'] ),
'post_content' => $_POST['post_content'],
'post_status' => 'publish',
'post_author' => 1,
'post_category' => array( 8, 39 )
);
// Insert the post into the database
$post_id = wp_insert_post( $post_data );
Emoji Note
Since version 4.2, with the introduction of emoji support, the function automatically converts emoji characters in 'post_title', 'post_content', and 'post_excerpt' fields if the table encoding is utf8, not utf8mb4. The wp_encode_emoji() function is applied to these fields.
Returns
Int|WP_Error.
Post ID if the insertion was successful.
0 if $wp_error is disabled and an error occurs.
WP_Error object if $wp_error is enabled and an error occurs.
Usage Template
$post_data = [
'ID' => <post id>,
'menu_order' => <order>,
'comment_status' => 'closed' | 'open',
'ping_status' => 'closed' | 'open',
'pinged' => ?,
'post_author' => <user ID>,
'post_content' => <the text of the post>,
'post_date' => Y-m-d H:i:s,
'post_date_gmt' => Y-m-d H:i:s,
'post_excerpt' => <an excerpt>,
'post_name' => <the name>,
'post_parent' => <post ID>,
'post_password' => ?,
'post_status' => 'draft' | 'publish' | 'pending' | 'future' | 'private',
'post_title' => <the title>,
'post_type' => 'post' | 'page' | 'link' | 'nav_menu_item' | custom post type,
'post_category' => array( <category id>, <...> ),
'tags_input' => array( <tag>, <tag>, <...> ),
'tax_input' => array( 'taxonomy_name' => array( 'term', 'term2', 'term3' ) ),
'to_ping' => ?,
'meta_input' => [ 'meta_key'=>'meta_value' ],
];
$post_id = wp_insert_post( wp_slash( $post_data ) );
Usage
$post_id = wp_insert_post( $postarr, $wp_error, $fire_after_hooks );
$postarr(array) (required)
An array of data to be inserted into the database. The keys must match the columns in the wp_posts table, and the values will be inserted into the corresponding columns.
If you specify an ID, the function updates the post instead of creating a new one.
ID (int) Default: 0.
post_author (int) Default: Current user ID.
post_date (string) Y-m-d H:i:s .Default: Current time.
post_date_gmt (string) Y-m-d H:i:s .Default: Derived from $post_date .
post_content (string) Default: ''
post_content_filtered (string) Default: ''
post_title (string) Default: ''
post_excerpt (string) Default: ''
post_status (string)
If the status is future , you must specify the post_date to schedule the post.
Default: 'draft'.
post_type (string) 'post' | 'page' | 'link' | 'nav_menu_item' | custom post type .Default: 'post'.
comment_status (string) Default: 'default_comment_status' option value.
ping_status (string) Default: 'default_ping_status' option value.
post_password (string) Default: ''
post_name (string) sanitize_title() .Default: Sanitized title.
to_ping (string) Default: Empty.
pinged (string) Default: Empty.
post_parent (int) Default: 0
menu_order (int) Default: 0
post_mime_type (string) Default: ''
guid (string) Default: Empty.
import_id (int) Default: 0.
post_category (int[]) [ cat, cat2, ... ] .Default: 'default_category' option value.
tags_input (array) [ tag, tag2, ... ] .Default: Empty.
tax_input (array) [ 'tax_name' => [ 'term', 'term2' ] ] .
Default: Empty.
meta_input (array) [ 'meta_key' => 'meta_value' ] .Default: Empty
page_template (string)
Note: The page_template field was removed. Page templates are now set using the _wp_page_template meta-field, which stores the name of the PHP template file.
$wp_error(bool)
Set to true to return a WP_Error object on failure.Default: false
$fire_after_hooks(bool) (WP 5.6)
Whether to run the wp_after_insert_post() function, which triggers hooks after the function completes.Default: true
Examples
In the data array passed to the function, at least the post_title and post_content keys must be specified; otherwise, the post will not be created. Values for other important but unspecified fields, such as post_date and post_author , will be generated automatically.
#1 A simple example of inserting a new post into a WordPress Database
// Create an array
$post_data = array(
'post_title' => 'Заголовок записи',
'post_content' => 'Здесь должен быть контент (текст) записи.',
'post_status' => 'publish',
'post_author' => 1,
'post_category' => array(8,39)
);
// Insert data into database
$post_id = wp_insert_post( wp_slash($post_data) );
Categories must be passed in the array, even if one category is specified. For example: 'post_category' => array(8)
#2 Insert the post and check for errors
$post_id = wp_insert_post( $POST['post_data'], true );
if( is_wp_error($post_id) ){
echo $post_id->get_error_message();
}
else {
// you can now use $post_id to add, for example
// meta field using add_post_meta() or update_post_meta()
}
#3 Insert post with custom taxonomy and post meta data
$post_arr = array(
'post_title' => 'Test post',
'post_content' => 'Test post content',
'post_status' => 'publish',
'post_author' => get_current_user_id(),
'tax_input' => array(
'hierarchical_tax' => array( 13, 10 ),
'non_hierarchical_tax' => 'tax name 1, tax name 2',
),
'meta_input' => array(
'test_meta_key' => 'value of test_meta_key',
),
);
