在HTML中有(form-data)
变化
<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 $id; ?>" method="post" enctype="multipart/form-data">
后并未奏效...... – user3733306
什么是不工作？您是否正在做的print_r（$后）的$ _FILES – Anish
在你的HTML中的错字，在form必须是enctype="multipart/form-data"，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']上的insertup.php 1线你的病情很可能是空的，所以它改成
if($_POST["cname"] != "" && $_POST["desc"] != "" && !empty($_FILES["image"]["name"])) {
值混得insertup.php值不是从edit.php页移动到页面insertup.php ...... plz帮助 – user3733306
如果固定'ENCTYPE 'attr，并且文件输入真的有'name = image'，它应该可以工作。 – panther
what's的print_r（$ _ FILES）的'输出;'？ – panther
它显示阵列（）........ print_r的 – user3733306
