注意：未定义索引：php 中的文件

Question

拜托，我在上传图片时遇到问题事实上，有我的代码： - 这是我的 html 表格：

            <div class="galery-upload">
                    <form action="include/galery-upload.inc.php" method="post" enctype="multipart/form-data">
                          <input type="file" name="filename">

                           <button type="submit" name="galery-upload-submit">UPLOAD</button>

                    </form>

                </div>

-这是 php 代码：

 <?php
$conn = mysqli_connect("localhost","root","","imguploads");
session_start();
$useruid =  $_SESSION['useruid'];
if (isset($_POST['galery-upload-submit'])) {
    $file = $_FILES['file'];
    if (empty($file)) {
        echo "no exist file";
    }
    else {


    $filename = $_FILES['file']['name'];
    $fileTmpName = $_FILES['file']['tmp_name'];
    $fileSize = $_FILES['file']['size'];
    $fileExt = explode('.',$filename);
    $fileActualExt = end($fileExt);
    $fileNameNew = "galery".".".uniqid($useruid, true).".".$fileActualExt ;
    $folder = "C:/xampp2/htdocs/miniprojet/galery/".$fileNameNew;
    move_uploaded_file($fileTmpName, $folder);
    }}
    ?>

并得到这个错误：注意：Undefined index: file in C:\xampp2\htdocs\miniprojet\include\galery-upload.inc.php on line 6 不存在文件

请提供任何解决方案!!!!!

Answer 1

您输入的名字是filename 所以：

$file = $_FILES['filename'];

注意：未定义索引：php 中的文件

Notice: Undefined index: file in php

php

upload

file
