因此，我正在上载一个图像文件，该文件可与以下代码一起使用，但它不会出现在媒体库中。我收到一条“文件有效，已成功上载”的消息，但我必须错过一个步骤。

if ( ! function_exists( \'wp_handle_upload\' ) ) {
require_once( ABSPATH . \'wp-admin/includes/file.php\' );
}

$files = array(\'tmp_name\' => $_FILES[$fieldname][\'tmp_name\'],
            \'name\' => $_FILES[$fieldname][\'name\']);



$overrides = array( \'test_form\' => false,
                \'action\' => \'to_be\',
                \'mimes\' => false);

$movefile = @wp_handle_upload( $files, $overrides );

if ( $movefile && !isset( $movefile[\'error\'] ) ) {
echo "File is valid, and was successfully uploaded.\\n";

} else {
/**
 * Error generated by _wp_handle_upload()
 * @see _wp_handle_upload() in wp-admin/includes/file.php
 */
echo $movefile[\'error\'];
