Question

我想一次上传多个文件。我已经成功测试了单个文件上传的代码（删除了每个循环）然后它全部工作。文件正在上传并检查文件大小/文件类型。但是当我尝试输入for循环以便能够执行多个文件时，它返回＆＃34; 不允许使用此文件扩展名，请上传JPEG或PNG文件 ＆＃34;

HTML代码：

    <form action="fileUpload.php" method="POST" enctype="multipart/form-data">
    <table>
        <tr><td>File 1</td> <td><input name="file_upload[]" type="file" class="multi"/> </td></tr>
        <tr><td>File 2</td> <td><input name="file_upload[]" type="file" class="multi"/> </td></tr>
        <tr><td></td> <td> <input type="submit" name="upload" value="Upload"><input type="reset"> </td> </tr>
    </table>
    </form>

PHP代码：

    foreach ($_FILES['file_upload']['tmp_name'] as $key => $tmp_name)
    {

            $rootDir = getcwd(); // get current working directory

            $uploadDirectory = "/uploads/";     

            $fileExtensions = ['jpeg','jpg','png', 'pdf', 'docx',]; // Get all the file extensions

            $fileType = $_FILES['file_upload']['type'][$key];
            // $fileExtension = strtolower(end(explode('.',$fileName)));
            $fileExtension = pathinfo($_FILES["file_upload"]["tmp_name"][$key]);

            $uploadPath = $rootDir . $uploadDirectory . basename($fileName); 

            // echo $uploadPath;


    }

?>

Answer 1

更改：

$fileExtension = pathinfo($_FILES["file_upload"]["tmp_name"][$key]);

到：

$fileExtension = pathinfo($_FILES["file_upload"]["name"][$key]);
$fileExtension = $fileExtension['extension'];

以前，您的代码会检查临时文件扩展名。
