PHP - невозможно просмотреть загруженные файлы PDF

0 голосов
/ 13 апреля 2020

Я работаю над проектом php, имеющим функцию загрузки и скачивания pdf-файлов.

Я загружаю его после загрузки в моем браузере и сообщает, что не удалось загрузить документ PDF

см. Мой код. 

<?php

  require 'connection.php';

  if(isset($_POST['submit']))
  {
      //$insertquery = "insert into upload(department,year,semester,subject,doc,select_d) values('$department','$year','$semester','$subject','$doc','$select_d')";

      $uploadOk=1;
      $fileName=$_FILES['fileToUpload']['name'];
            $fileName=str_replace(' ', '', $fileName);
      $errorMessage="";
      $fileSize="";
      $fileExt="";

      if($_FILES['fileToUpload']['name']) 
      {
        $targetDir = "ss1/";
        $fileName = $targetDir . uniqid().basename($fileName);
        $fileSize = $_FILES['fileToUpload']['size'];
        $fileType = pathinfo($fileName, PATHINFO_EXTENSION);
        $fileExt = strtolower($fileType);

        if($_FILES['fileToUpload']['size'] > 10000000)
        {
          $errorMessage = "Sorry, your file is too large";
          $uploadOk = 0;
        }

        if(strtolower($fileType) != "pdf" && strtolower($fileType) != "doc")
        {
          $errorMessage = "Sorry, only pdf and docs files are allowed";
          $uploadOk = 0;
        }

        if($uploadOk) 
        {
          if(move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $fileName)) 
          {


          if (file_exists($fileName)) {
    echo "Sorry, file already exists.";
  }
           }
          else 
          {

            $uploadOk = 0;
          }

        }



      }


      if($uploadOk) 
      {
        $department = $_POST['department'];
        $year = $_POST['year'];
        $semester = $_POST['semester'];
        $subject = $_POST['subject'];
        $doc = $_POST['doc'];
        $select_d = $_POST['fileToUpload'];

        $fileName = $fileName;
        header("Content-type: application/pdf");
        header("Content-Length: " . fileSize($fileName));
        header('Content-Disposition: attachment; filename="'  .$fileName.'"');
        readfile($fileName);


      // $check=mysqli_query($con,"SELECT * FROM upload WHERE department='$department' AND year='$year'");
       if(mysqli_num_rows($check) == 0)
        {
          $query=mysqli_query($con,"INSERT INTO upload VALUES('','$department','$year','$semester','$subject','$doc','$fileName')");
        }

      }
