这是php＆html文件。截至目前，我能够使用文件上传名称进行上传。我的目标是将文件名更改为“ newfilestring”的格式（已注释掉），然后添加已上传文件的扩展名。我已经测试了多种方法和教程，但没有一个起作用。任何反馈将不胜感激。

当前格式-> example.pdf

所需格式-> date-firstname-lastname-extension

Answer 1

您可以使用

$extension = pathinfo($fileName, PATHINFO_EXTENSION);
$targetFilePath = $targetDir.$date.'-'.$firstName.'-'.$lastname.'.'.$extension;

重命名文件。

Answer 2

添加类似这样的内容：

$newFileName = $date.$lastname.$firstname.'.'.$extension; //如果这些变量已在其他位置提供

然后在移动文件时使用它：

if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetDir.$newFileName )){ //等等

尚未对此进行测试，但是希望可以将您带入正确的轨道...

已更新：尝试以下操作：

$date = date('m-d-Y');
if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
    // Allow certain file formats
    $targetDir = "C:/xampp/htdocs/uploaded-file/";
    $fileName = basename($_FILES["file"]["name"]);
    $filename_array = explode(".",$fileName ); // get file name
    $extension = $filename_array[1]; // second portion of file name - extension
    $targetFilePath = $targetDir.$fileName;
    $newFileName = $date.$lastname.$firstname.'.'.$extension;

    $allowTypes = array('jpg','png','jpeg','gif','pdf','xlsx');
    $empid = $_SESSION['id'];

    if(in_array($extension, $allowTypes)){
        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetDir.$newFileName )){
            // Insert image file name into database
            $insert = $con->query("INSERT into fileupload (filename, dateuploaded,empid) VALUES ('".$fileName."', NOW(), '".$empid."')");
            if($insert){
                $statusMsg = "Your timesheet: ".$fileName. " has been uploaded successfully.";
            }else{
                $statusMsg = "File upload failed, please try again.";
            }
        }else{
            $statusMsg = "Sorry, there was an error uploading your file.";
        }
    }else{
        $statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, xlsx & PDF files are allowed to upload.';
    }
}else{
    $statusMsg = 'Please select a file to upload.';
}

在使用move_uploaded_file上传到文件路径之前更改文件名
