I'd be so very grateful if you could give me the snippet for uploading videos to the media attachment. I'm using a external uploader and saving the data to a form field, which saves the URL to the custom field and then executes the above function but it doesn't seem to work.

`add_action('cred_save_data', 'my_save_data_action',10,2);
function my_save_data_action($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==3799810)
{
if (isset($_POST['wpcf-original-video']))
{
$file = $_POST['wpcf-original-video'];
function add_attachment_from_url( $file ) {
$file_array = array();
$file_array['name'] = wp_basename( $file );

    	// Download file to temp location.
    	$file_array['tmp_name'] = download_url( $file );

    	// If error storing temporarily, return the error.
    	if ( is_wp_error( $file_array['tmp_name'] ) ) {
        return $file_array['tmp_name'];
    	}

    	// Do the validation and storage stuff.
    	$id = media_handle_sideload( $file_array, 0, null );

		add_post_meta($post_id, 'wpcf-attached-video-id', $id, true);

    	}
}

}
}`

Hey there, I'm using following functions to set Woo-commerce featured image 👍

$product = wc_get_product( $product_id);
$image_id = media_sideload_image("$img_url_base/main.jpg", $product->get_id(), $product->get_title(), 'id');
if (!is_wp_error($image_id) && is_numeric($image_id)){
   $product->set_image_id($image_id); // add featured image of product
   $product->save();
}

Thankyou!
Very useful

I'm really new to this but was wondering where I should insert this snippet into? Another file or save the whole php file into a certain folder.

Works perfectly, thanks bro ^^

Very very very nice work!
Thanks bro!

Thanks alot!!!

Genial, funcionó perfecto!!!! Gracias

This is killer. Thank you!

if facing function error. you need to include these two files.

    include(ABSPATH . "wp-includes/pluggable.php");
    include_once( ABSPATH . '/wp-admin/includes/image.php' );

In addition add a slash to the class instance if you are on a namespaced class

$http = new \WP_Http();

I've haven't work with Wordpress in quite a while, but if I'm not mistaken, if you are facing this issue its because you are running the script somewhere where the necessary wordpress functions are not being included. The solution shouldn't be to include the scripts manually, but to run it in the correct environment. Whish I could be of more help, but I'm rusty with Wordpress atm .

hand down thanks
