使用php将文件上载到服务器

很好，很高兴见到你

我有一个与Angula，Laravel和Bootstrap的项目，我正在创建一个表格，以便能够通过项目的网站上传文件到服务器，我已经把这个代码放在下面，它不能正常工作，你能帮我告诉我我必须放的代码，或者告诉我哪里失败了

等待您的回答，接受诚挚的问候

多谢各位

这是在我的HTML中

<div class="container">
  <div class="row">
    <form method="post" action="test_act.php" enctype="multipart/form-data">
      <div>
        <span>Choose file</span>  
           <input type="file" name="fileToUpload" id="fileToUpload"><br/>
              <input type="submit" name="fupload" id="fupload">
       </div> 
     </form>
  </div>
</div>

选择文件

test_act.php

<?php 
include ("test_cls.php");
if(isset($_POST['fupload']))
{
    $dirpath="upload";
    $uploader   =   new Uploader();

    $uploader->setExtensions(array('jpg','jpeg','png','gif','doc','docx', 'pdf'));  //allowed extensions list//

    $uploader->setMaxSize(1);                          //set max file size to be allowed in MB//

    $uploader->setDir($dirpath);

    if($uploader->uploadFile('fileToUpload'))          //txtFile is the filebrowse element name //
    {   
        $suc_file  =   $uploader->getUploadName(); //get uploaded file name, renames on upload//
        echo $suc_file." successfully uploaded";
    }
    else                    //upload failed
        echo $uploader->getMessage(); //get upload error message
}
?>

test_cls.php（上传类）

您的代码运行正常

但是，您可以检查：

• 是否创建了上载目录
• 上载目录是否具有所需的权限
• 您的文件未超过php.ini定义的上载限制大小

您好，很高兴向您致意，感谢您的快速回复，我已经测试了权限，php.ini为10MB，我知道这是正确的，默认情况下，我只在服务器上创建上载文件夹，我必须在服务器上的何处创建上载文件夹？等待您的回复，收到诚挚的问候，非常感谢，您好。我的荣幸。这并不是因为当前用户拥有www数据用户（如果使用Apahce）所需的权限。小心！你的开发环境是什么（PHP版本，OS，…）？嘿@Aaron_Actu我试着调试submit按钮，我注意到它没有执行任何代码。我不知道为什么，我会设法找到一个解决办法，但如果你能帮我一把，那将是非常有帮助的。你能给我们发一张代码所在目录的照片吗？
