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_1085' );
function filter_function_name_1085( $error ){
// filter...
return $error;
}
- $error(true|false)
- Whether to pre-empt the media upload.
Default: false
