Question

我写了php脚本来从管理面板上传文件并为用户下载。上传成功完成但下载文件后无法读取。如果是图像文件或pdf文件。上传的文件将复制到xamp / htdocs / myproject / admin / documents。并将路径存储到mysql数据库中。当我尝试下载它时，上传文件和下载文件的文件大小不同，无法读取。

上传脚本

if (isset($_POST['submit'])){ 
 $name = $_FILES['myfile']['name'];
 $tmp_name = $_FILES['myfile']['tmp_name'];

if ($name) {
  $location = "documents/$name";
  move_uploaded_file($tmp_name, $location);
  $query = mysqli_query($con,"INSERT INTO posts (name,path) VALUES ('$location')");
}

Answer 1

感谢大家帮助我。我昨天对我的脚本进行了更改并且它正在运行，但问题是当我尝试将其添加到我的项目时它无效。

我的上传脚本（在myproject / admin / application.php中写入）

if (isset($_POST['submit'])){
   $name = $_FILES['myfile']['name'];
    $tmp_name = $_FILES['myfile']['tmp_name'];

if ($name) {
  $location = "documents/$name";
  move_uploaded_file($tmp_name, $location);
  $query = mysqli_query($con,"INSERT INTO posts (name,path) VALUES ('$location')");   
}

download.php（写在myproject / download.php中）

<?php
 include('includes/connect.php');
  if (isset($_GET['dow']))  {
     $path = $_GET['dow'];
      $res = mysqli_query("SELECT * FROM posts WHERE path = '$path'");

header('Content-Description: File Transfer');
header('Content-Type: application/force-download');
header("Content-Disposition: attachment; filename=\"" . basename($path) . "\";");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($path));
ob_clean();
flush();
readfile($path); //showing the path to the server where the file is to be download
exit;
   }


 ?>

download.php b的链接脚本（用myproject / viewprofile.php编写）

<?php
  include('includes/connect.php');

  $sql = "SELECT * FROM posts";
  $res = mysqli_query($con, $sql);






    $path   = $row['post_path'];

     echo "<a href='download.php?dow=$path' class='btn btn-dark btn-theme-colored btn-flat mr-5' style='width:100%; margin-top:5px;'> DOWNLOAD RESUME </a> <br>";

 ?>

在PHP
