【问题描述】：

这个功能，看起来很标准，我真的没有一个活动按钮来上传到我的数据库中的列表？

if(isset($_POST['submit'])) //THis is how you upload a picture to a website
    $file = $_FILES['file'];
    print_r($file);

    $fileName = $_FILES['file']['name'];
    $fileTmpName = $_FILES['file']['tmp_name'];
    $fileSize = $_FILES['file']['size'];
    $fileError = $_FILES['file']['error'];
    $fileType = $_FILES['file']['type'];

    $fileExt = explode('.', $fileName);
    $fileActualExt = strtolower(end($fileExt));

    //array for
    $allowed = array('jpg', 'jpeg', 'png', 'pdf');

    if(in_array($fileActualExt, $allowed))
        if($fileError === 0) 
            if($fileSize < 1000000) 
                $fileNameNew = uniqid ('',true). ".". $fileActualExt;
                $fileDestination = '_uploads/'. $fileNameNew;
                move_uploaded_file($fileTmpName);
                header("Location: index.php");
                echo "success";
            elseecho "Your file is too big hoe";
        
        elseecho "good try, youll have to upload again";
    
    elseecho "You cannot upload file of this type";


echo $_POST['value'];
//if $_POST == "yes"

$encodedStr = base64_encode('yes.txt'); //may need to encode inside of a seperate function
//may need to implement a search based on user input
//if search matches the stored access value, then decode the .txt document
echo $encodedStr; //cannot concat a string by itself, must make into a numeric value
$decodedStr = base64_decode ($encodedStr);
echo nl2br($decodedStr);

?>

上面的代码有什么不寻常的地方吗？ php新手。

【问题讨论】：

这段代码没有必须显示上传按钮的部分（我理解你想要的），但是如果你发送一个包含这个脚本的地址的 Post 请求，它应该上传它。能否请您为我重新说明问题？

试试这个来上传图片。
