Answer 1

要使file输入正常工作，您需要指定表单的enctype。您需要enctype="multipart/form-data"。有关详细信息，请参阅PHP POST uploads。

Answer 2

 <form method="post" action="insert_file.php" enctype='multipart/form-data'>

原因：当您发出POST请求时，您必须以某种方式对构成请求主体的数据进行编码。

HTML表单提供了两种编码方法。默认值为application / x-www-form-urlencoded，它与URL末尾的查询字符串大致相同。另一个是multipart / form-data，是一种更复杂的编码，但允许将整个文件包含在数据中。（HTML 5引入了text / plain编码，它只对调试很有用......即使这样，其他人也可以使用合理的调试工具。）
