if (isset ($name)) {
    if (!empty($name)) {

    $location = 'uploads/';

    if  (move_uploaded_file($tmp_name, $location.$name)){
        echo 'Uploaded';    
        }

        } else {
          echo 'please choose a file';
          }

我收到通知:未定義索引"錯誤消息.enctype 包含在表單標簽中，所以我無法弄清楚它是什么.. 任何人都可以幫助我嗎??

i get an 'Notice: Undefined index' error message. The enctype is included in the form tag so i can't figure out what it is.. can anyone help me out??

推薦答案

第一次賦值拋出警告，如果什么都沒上傳，而且isset測試有點沒用..

The first assignment throws an warning, if nothing is uploaded and the isset test is a little bit useless..

您可以按如下方式更改代碼

You can change your code as follows

<?php

if (isset($_FILES["file"]["name"])) {

    $name = $_FILES["file"]["name"];
    $tmp_name = $_FILES['file']['tmp_name'];
    $error = $_FILES['file']['error'];

    if (!empty($name)) {
        $location = 'uploads/';

        if  (move_uploaded_file($tmp_name, $location.$name)){
            echo 'Uploaded';
        }

    } else {
        echo 'please choose a file';
    }
}
?>

<form action="test.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" value="Submit">
</form>
