_FILES['file1']['tmp_name'] is empty when tried to upload file in php

本文关键字：文件 name file1 FILES tmp php | 更新日期: 2023-09-27

这个问题几天前就出现了。该脚本在本地主机和另一台在线服务器上运行良好。希望得到回应。我无法在服务器上上传文件。

    //$target_path = $target_path ."testpankaj".".".$ext;

        echo $_FILES['file1']['tmp_name'];
    if(move_uploaded_file($_FILES['file1']['tmp_name'], "images/" . $_FILES["file1"]['name'])) {
           echo "The file ".  basename( $_FILES['file1']['name']). 
        " has been uploaded";
        } else{
            echo "There was an error uploading the file, please try again!";
        }
    }
    ?>

if(isset($_POST['save']))

我认为这就是问题所在。输入似乎没有被定义。只需添加它，像这样:

<input type="submit" name="save" id="save" value="sent" />
