I am inserting some post into wordpress using the function wp_insert_post().
I want to insert some custom fields on each post and reading the documentation I though the meta_info parameter was used for that, I tried something like this:
$data = array(
'post_author' => 1,
'post_status' => 'publish',
'post_title' => $post->getTitle(),
'post_content' => $post->getContent(),
'post_category' => $post->getCategory(),
'tags_input' => $post->getTags(),
'meta_input' => array( "_test" => "testx1" )
);
$postID = wp_insert_post( $data );
The post gets inserted correctly and tags too. But there are no custom fields added. I know I could use add_post_meta() to add them but I still would like to know what the meta_input parameter is used for, because I did a search on the database for "testx1" after inserting the post and couldn't find any result.

Reset to default 7This part of wp_insert_posts() gives it away:
if ( ! empty( $postarr['meta_input'] ) ) {
foreach ( $postarr['meta_input'] as $field => $value ) {
update_post_meta( $post_ID, $field, $value );
}
}
where we see how the post meta fields are updated/added with update_post_meta().
Here's the inline description for meta_input:
Array of post meta values keyed by their post meta key. Default empty.
This was added in WordPress 4.4 and here's relevant ticket #20451 for more information.
Note that using the underscore in front of the the meta key _test will hide it from the custom fields metabox in the post edit screen.
The way I do it is via term_id not slug and it works:
//insert Art items into database
$arr = array('item 1', 'item 2');
// $arr = array('art item 1', 'art item 2');
foreach ($arr as $a) {
wp_insert_post(array(
//essentials
//'ID' => 1131,
'post_author' => 1,
'post_title' => $a,
'post_type' => 'post',
'post_content' => 'Something...',
'post_status' => 'publish',
'post_name' => 'post name',
'meta_input' => array( //(array) Array of post meta values keyed by their post meta key. Default empty.
'city' => '',// 'name' => $post['name']
'country' => ''// 'city' => $post['city']
),
'tax_input' => array(
'category' => array(33,32), //id numbers work, slugs tend to be ignored !!!
'post_tag' => array('one', 'two') //for tags slugs seem to work
),//(array) Array of taxonomy terms keyed by their taxonomy name. Default empty. Equivalent to calling wp_set_post_terms() / wp_set_object_terms()
//'tags_input' => array('una', 'trei'), //(array) Array of tag names, slugs, or IDs. Default empty. Equivalent to calling wp_set_post_tags().
), true);
}
