我有这个代码，但我无法解决它的问题。任何帮助将不胜感激。请不要太快将它标记为副本而不给我一个解决方案，因为我已经完成了所有相似的问题并且他们没有回答我的问题，因为我已经检查了文件是否上传是为了处理它仍然得到这个错误UNDEFINED INDEX：

ERROR :)注意：未定义的索引：
中的fileToUpload答案 0 :(得分：1)
更改以下内容：
<form role="form" method="post" action="test2.php">
到
<form role="form" method="post" action="test2.php" enctype="multipart/form-data">
在尝试访问var之前还会检查var是否存在，可以使用
if(isset($_FILES['fileToUpload']){do something}else{error!}
另外建议您在html之前移动PHP代码。
答案 1 :(得分：1)
正如w3schools.com所说，您需要向表单添加enctype="multipart/form-data"。
multipart / form-data
不编码任何字符。使用具有文件上载控件的表单时，此值是必需的
所以改变这一行
<form role="form" method="post" action="test2.php">
到这个
<form role="form" method="post" action="test2.php" enctype="multipart/form-data">
