pre_upload_error filter-hook . WP 2.1.0

Filters whether to preempt the XML-RPC media upload.

Passing a truthy value will effectively short-circuit the media upload, returning that value as a 500 error instead.

Usage

add_filter( 'pre_upload_error', 'filter_function_name_6955' );
function filter_function_name_6955( $error ){
	// filter...

	return $error;
}

$error(true/false)

Whether to pre-empt the media upload.
Default: false
