PHP文件上传并重命名为特定名称以覆盖以前的版本

Question

我正在尝试通过创建一个小型上传表单将 PDF 上传到菜单目录并为其指定特定名称以覆盖以前的版本，从而使一些同事可以轻松地在线更新菜单（两个 PDF）。

这是我目前所拥有的......

表格：

<section>
<form action="menu_uploader.php" method="post" id="menu_upload" name="menu_upload" enctype="multipart/form-data" >
<p><label for="wine_list_menu_upload">Wine List -> </label>&nbsp;<input type="file" name="wine_list_menu_upload" id="wine_list_menu_upload"></p>
<p><label for="food_flight_menu_upload">Food &amp; Flights -> </label>&nbsp;<input type="file" name="food_flight_menu_upload" id="food_flight_menu_upload"></p>
<p><input type="submit" name="submit" value="Upload" id="submit"></p>
</form>
</section>

PHP

<?php

if( ($_FILES["wine_list_menu_upload"]["type"] == "application/pdf") &&
    ($_FILES["food_flight_menu_upload"]["type"] == "application/pdf") &&
    ($_FILES["wine_list_menu_upload"]["size"] < 1048576*5) && 
    ($_FILES["food_flight_menu_upload"]["size"] < 1048576*5))
    {   
        if($_FILES["wine_list_menu_upload"]["error"] > 0 || $_FILES["food_flight_menu_upload"]["error"] > 0)    
            {echo "Error Code: " . $_FILES["wine_list_menu_upload"]["error"] xor $_FILES["food_flight_menu_upload"]["error"] . "<br>";}
                else
                    {move_uploaded_file($_FILES["wine_list_menu_upload"]["tmp_name"], "tasting-bar/menus/test/SEWC-Wine_Menu.pdf");
                     move_uploaded_file($_FILES["food_flight_menu_upload"]["tmp_name"], "tasting-bar/menus/test/SEWC-Food_Flight_Menu.pdf");
                        echo "Menus uploaded successfully!"; }
    }

else
  {
  echo "Invalid file type. Must be a PDF and under 5MB. Sorry!<br/>";
  echo "File Type - " . $_FILES["wine_list_menu_upload"]["type"] . "<br/>";
  echo "File Name - " . $_FILES["wine_list_menu_upload"]["name"];

  }

?>

我需要将“wine_list_menu_upload”重命名为“SEWC-Wine_Menu.pdf”并改名为“tasting-bar/menus/”和 “food_flight_menu_upload”重命名为“SEWC-Food_Flight_Menu.pdf”并改名为“tasting-bar/menus/”

我做错了什么？

Answer 1

尝试在 move_uploaded_file 之前添加这些行

chmod('tasting-bar/', 0777);
chmod('tasting-bar/menus', 0777);
chmod('tasting-bar/menus/test/', 0777);

如果是权限问题，应该这样解决
