当查看file.module文件时,
function file_ajax_progress($key) {
$progress = array(
'message' => t('Starting upload...'),
'percentage' => -1,
);
$implementation = file_progress_implementation();
if ($implementation == 'uploadprogress') {
$status = uploadprogress_get_info($key);
if (isset($status['bytes_uploaded']) && !empty($status['bytes_total'])) {
$progress['message'] = t('Uploading... (@current of @total)', array('@current' => format_size($status['bytes_uploaded']), '@total' => format_size($status['bytes_total'])));
$progress['percentage'] = round(100 * $status['bytes_uploaded'] / $status['bytes_total']);
}
}
elseif ($implementation == 'apc') {
$status = apc_fetch('upload_'.$key);
if (isset($status['current']) && !empty($status['total'])) {
$progress['message'] = t('Uploading... (@current of @total)', array('@current' => format_size($status['current']), '@total' => format_size($status['total'])));
$progress['percentage'] = round(100 * $status['current'] / $status['total']);
}
}
error_log( $status['current'].'-------'.$status['total'].'-----'.$key );
drupal_json_output($progress);
}
在上述代码中,$status中本因记录文件的上传的大小和总的大小,但现在,$status中没有任何的值,求解决办法?????
