当我提交下面的表格时，我得到了一个未定义索引“商店”的错误，当我给“提交”按钮命名并测试它是否存在（isset）时，我的回答很不令人满意，这是我的代码：

PS：只有在加载视频时才能发生，上传照片时效果很好，欢迎任何帮助
答案 0 :(得分：0)
大约在代码中间，
// Valid file extensions
$extensions_arr = array("mp4","avi","3gp","mov","mpeg");
// Check extension
if (in_array($videoFileType, $extensions_arr)) {
if (($_FILES['video']['size'] >= $maxsize) || ($_FILES["video"]["size"] == 0)) {
// do stuff
因此，您的代码正在检查您上传的文件是否在$extensions_arr中具有任何扩展名（.mp4，.avi，.3gp，.mov，.mpeg）。
上传文件后，它会检查文件大小，并确保文件大小不大于0也不大于最大文件大小。顺便说一句，为了使其更具可读性，为什么不只使用
if (in_array($videoFileType, $extensions_arr)) {
if (($_FILES['video']['size'] <= $maxsize) || ($_FILES["video"]["size"] > 0)) {
// do stuff
并检查文件大小是否小于最大大小但大于0？
这里的问题是您没有在代码中的任何地方声明$shop，也许您是说$target_file？
