Populate WordPress Advanced Custom Fields with remote JSON in backend - json

Question

I have custom post types called "Products". and using the AFC(Advanced Custom Fields) plugin with this post type.
Below is what ACF has in fields group
- one filed called 'Product Description' as text area
- three text fields called 'Feature 1, Feature 2,Feature 3'
What I want to achieve is to get the data from external JSON file and populate the above ACF fields in the backend. I did some research and found Wordpress offers wp_remote_get() function to request the remote file. But I have no clue where to begin with to use this function or any other approach to use external JSON and populate these fields. Will really appreciate it someone points me to the right direction or any tutorial that shows how to achieve that. Thanks

Answer 1

I figured it out. View the working code below.
// Get JSON and Decode
$json_request = wp_remote_get( 'http://wp-test/test/data.json');
if( is_wp_error( $json_request ) ) {
return false;
}
$json_body = wp_remote_retrieve_body( $json_request );
$json_data = json_decode( $json_body );
// Create the new post and populate the fields
foreach( $json_data->products as $item ) {
$title = $item->title;
$desc = $item->content;
$status = $item->status;
$new_post = array(
'post_title' => $title,
'post_content' => $desc,
'post_status' => $status,
'post_author' => $userID,
'post_type' => 'products'
);
$post_id = post_exists( $title );
if (!$post_id) {
$post_id = wp_insert_post($new_post);
}
}
