HTML PHP文件上传错误

已采纳

I am trying to upload a PDF file, but getting the "Invalid File" error. I have used the code from w3schools, but its not working. Here is the PHP code

    $allowedExts = array("pdf");
    $temp = explode(".", $_FILES["pdfFile"]["name"]);
    $extension = end($temp);
    if ((($_FILES["pdfFile"]["type"] == "application/pdf"))
    && ($_FILES["pdfFile"]["size"] < 1200000)
    && in_array($extension, $allowedExts))
      {
      if ($_FILES["pdfFile"]["error"] > 0)
        {
        echo "Return Code: " . $_FILES["pdfFile"]["error"] . "<br>";
        }
      else
        {
        echo "Upload: " . $_FILES["pdfFile"]["name"] . "<br>";
        echo "Type: " . $_FILES["pdfFile"]["type"] . "<br>";
        echo "Size: " . ($_FILES["pdfFile"]["size"] / 1024) . " kB<br>";
        echo "Temp file: " . $_FILES["pdfFile"]["tmp_name"] . "<br>";

        if (file_exists("../assets/pdf/" . $_FILES["pdfFile"]["name"]))
          {
          echo $_FILES["pdfFile"]["name"] . " already exists. ";
          }
        else
          {
          move_uploaded_file($_FILES["pdfFile"]["tmp_name"],
          "../assets/pdf/" . $_FILES["pdfFile"]["name"]);
          echo "Stored in: " . "../assets/pdf/" . $_FILES["pdfFile"]["name"];
          }
        }
      }
    else
      {
      echo "Invalid file";
      }

    Could you just check (by echo, var_dump or whatever suits you) the content of $_FILES["pdfFile"] ? Are you sure it fits ?

    And you did set the enctype of Your upload form as well ? http://www.w3schools.com/tags/att_form_enctype.asp

    And the form method is equal POST ?

    Could this be a problem with file permissions?

    Check if you have permission to write to folder ../assets/pdf/.
