Answer 1

在您的HTML上，(form-data)

中存在拼写错误

更改

<form name="myform" action="insertup.php?id=<?php echo $id; ?>" method="post" enctype="multipart/form_data">

到

<form name="myform" action="insertup.php?id=<?php echo $id; ?>" method="post" enctype="multipart/form-data">

Answer 2

在您的HTML中，form必须是enctype="multipart/form-data"，而不是enctype="multipart/form_data"。

<form name="myform" action="insertup.php?id=<?php echo $id; ?>" method="post" enctype="multipart/form-data">

然后，$_POST['image']第1行条件中的insertup.php可能为空，请将其更改为

if($_POST["cname"] != "" && $_POST["desc"] != "" && !empty($_FILES["image"]["name"])) {

$ path =＆＃34; Image /＆＃34;。$ _ FILES [＆＃34; image＆＃34;] [＆＃34; name＆＃34;];
