Folder id null when adding image to woocommerce cart

(@tazziedave)

When adding an image to the media library programatically during the creation of a woocommerce product cart item, the following function is called.

  
public function add_attachment_to_folder2( $metadata, $attachment_id ) {
    
    $folder_id = $this->get_default_folder($attachment_id);
    //error_log("add_attachment_to_folder2 folder_id $folder_id");
    if($folder_id !== false) {
      $this->add_new_folder_parent($attachment_id, $folder_id);
      
    }
    return $metadata;
  }


$this->get_default_folder($attachment_id);

returns null and not false, causing a db error on the add function.

Since I do not have the code you are using to add an image, I am not able to reproduce this issue.

Sorry,

It’s in response to this hook:

add_filter( 'woocommerce_add_cart_item', [ $this, 'create_image_in_cart_item' ], 10, 2 );

The handling, i’m doing is


public function create_image_in_cart_item( $cart_item, $cart_item_key ): array {

// $cart_item['wcp_image_uri'] is base64 png data
	$imageUri = $cart_item['wcp_image_uri'] ?? false;
	if ( ! $imageUri ) {
		return $cart_item;
	}

	unset( $cart_item['wcp_image_uri'] );  // Don't need this any more

	// Extract info from the data uri and ensure that it seems valid
	list ( $image_info, $image_base64 ) = explode( ';base64,', $imageUri );
	$ext = substr( $image_info, - 3 );

	if ( ! $image_base64 || 'png' !== $ext ) {
		return $cart_item;
	}

	// Create path and filenames
	$upload_dir = wp_upload_dir();

	$session_hash = uniqid();
	$path         = $upload_dir['path'] . "/wcp_item_images/$session_hash";

	$product      = wc_get_product( $cart_item['product_id'] );
	$product_name = str_replace( ' ', '-', $product->get_name() );

	$filename = "$product_name-$cart_item_key.$ext";

	// Save it if we can
	try {
		if ( wp_mkdir_p( $path ) ) {
			$filename = $path . '/' . $filename;
		} else {
			$filename = $upload_dir['basedir'] . '/' . $filename;
		}
		file_put_contents( $filename, base64_decode( $image_base64 ) );
	} catch ( Exception $e ) {
		return $cart_item;
	}

	// Create attachment
	$wp_filetype = wp_check_filetype( $filename );
	$attachment  = [
		'post_mime_type' => $wp_filetype['type'],
		'post_title'     => sanitize_file_name( $filename ),
		'post_content'   => '',
		'post_status'    => 'inherit',
	];

	$attach_id            = wp_insert_attachment( $attachment, $filename );
	if (! $attach_id) {
		return $cart_item;
	}
	$this->currentImageId = $attach_id;
	$cart_item['wcp_image_attachment_id']   = $attach_id;
	$cart_item['wcp_image_filename']   = $filename;

	// Do all image processing and save image formats metadata
        require_once( get_admin_path() . '/includes/image.php' );
	$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
	wp_update_attachment_metadata( $attach_id, $attach_data );

	return $cart_item;
}

It is necessary to first add the new folder to the folder table. Here is some of your code:

$session_hash = uniqid();
$path         = $upload_dir['path'] . '/wcp_item_images/$session_hash';
...
                if ( wp_mkdir_p( $path ) ) {

After creating a folder it is necessary to add it using add_media_folder:

add_media_folder($folder_name, $parent_folder, $base_path)
$parent_folder is the ID number of the parent folder.

Let change add_media_folder() from a private function to a public one. Now you can use the following to call add_media_folder()

global $maxgalleria_media_library;
 $new_folder_id = $maxgalleria_media_library->add_media_folder($folder_name, $parent_folder, $base_path);

Once the folder has.been added then add_attachment_to_folder2() will be able to find the ID number of new the folder and return it rather than null.
