Question

我正在尝试创建一个PDF文件上传器，但我的if语句提前删除，否则语句会产生语法错误。有没有办法使这个IF工作？

错误：

if ($_FILES['file']['error'] !== UPLOAD_ERR_OK) {
    die("Upload failed with error " . $_FILES['file']['error']);
}
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $_FILES['file']['tmp_name']);
$ok = false;
switch ($mime) {
   case 'image/jpeg':
   case 'application/pdf':
        $ok = true;
   default:
       die("Unknown/not permitted file type");
}

  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

    if (file_exists("../pdf/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists: ";
      echo "<p>Image URL: <strong>" . $preferences->PREF_SHOPURL . "/pdf/" . $_FILES["file"]["name"] . "</strong></p>";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "../pdf/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "pdf/" . $_FILES["file"]["name"];
      echo "<p>&nbsp;</p>";
      echo "<p>PDF URL: <strong>" . $preferences->PREF_SHOPURL . "/pdf/" . $_FILES["file"]["name"] . "</strong></p>";
      }
    }

else
  {
  echo "Invalid file";
  }
?>

用户进入上传PDF页面的上传页面，然后运行upload_pdf2上传。

Upload.php

<?php
include_once("includes/session.php");
confirm_logged_in();
//include_once("includes/functions_admin.php");
include_once("../includes/masterinclude.php");

$message = "";
$scrolltobottom = "";


$preferences = getPreferences();

//note this will also refresh the page after amending it
$pageTitle = "Site Administration: Image Upload";

include_once("includes/header_admin.php");
?>
<div class="body-indexcontent_admin">
