我希望你做得很好。好的，我有这个曾经工作过的脚本。当我添加文件输入。它开始不起作用了。我检查了我的线路和所有。它应该制作，但我不知道它为什么不起作用。我希望你能帮助我。提前致谢

尝试将<form action="Sign_Up.php" method="post">转换为<form action="Sign_Up.php" method="post" enctype="multipart/form-data">
答案 1 :(得分：0)
你必须要处理两件事。首先，如果您要将图像图像发送到服务器，则必须在multipart/form-data中发送，然后您必须使用move_uploaded_file()
所以进行这些更改
<form action="Sign_Up.php" method="post" enctype="multipart/form-data">
和
if( isset($_FILES['ImageFile']['tmp_name']) )
{ $uploads_dir = '/uploads';
move_uploaded_file(($_FILES['ImageFile']['tmp_name'], "$uploads_dir/($_FILES['ImageFile']['name']");
$user->image = $_FILES['ImageFile']['name'];
}
希望它有所帮助：）
答案 2 :(得分：0)
您在'执行代码'的末尾缺少花括号}。
此外，由于您正在使用文件，因此您需要在表单中提供enctype="multipart/form-data"，如下所示：
<form action="Sign_Up.php" method="post" enctype="multipart/form-data">
$this->image = $row['Image'];不应直接插入数据库，因为它是一个关联数组。而是尝试"','". $this->image['name'] ."')";
如果要将图像保存在服务器上，则需要将其从临时目录中移出。在insert语句之后，您可以添加：
$uploads_dir = '/upload/path'; //path you want to move the file to
move_uploaded_file($this->image['tmp_name'], $uploads_dir . "/" . $this->image['name']); // move_uploaded_file($from_where, $to_here)
