我正在嘗試上傳多個文件到多個文件夾。不幸的是，收效甚微。多個文件上傳到多個文件夾 - PHP
任何幫助，將不勝感激
我有兩個表單字段：
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max; ?>" />
<input name="menu" type="file" class="input_event noBorder" title="Upload Menu" />
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max; ?>" />
<input name="img" type="file" class="input_event noBorder" title="Upload Img" />
我想用一個上傳圖像和其他上傳PDF格式的和/或Word文檔。 我還想將這兩個文件保存到相應的文件夾（/ imgs和/ docs）中。
有些事情我已經嘗試
- 都試圖擁有其中的兩個，每個指向正確的路徑
- 試圖多類來處理
- 添加陣列支架固定到每個文件輸入名稱字段（例如：
name="menu[]"）
我想我需要改變類中的某些東西;然而，我正在學習PHP，這個課程是從3本書，數十個谷歌搜索以及我在這裏找到的一些帖子拼湊在一起的。
正是我需要改變的地方仍然遠遠超出了我。
的對網頁PHP代碼相關部分：
$max = 400000;
if (isset($_POST['submit'])) { //MAIN IF STATEMENT
$destination = './uploads/menus_up/';
try {
$upload = new Upload_File($destination);
$upload->move();
$result = $upload->getMessages();
} catch (Exception $e) {
echo $e->getMessage();
}

這是很多上傳文件的代碼。你應該嘗試縮小問題的範圍。 – jeroen
是它有點過分;但我正在修補，然後認爲我會創建一個類，一次做所有的事情......錯誤處理，文件重命名，覆蓋保護等。不可否認，我有點被帶走了。但是，現在我花了這麼多時間在這件事上，我想完全完成它。不幸的是遇到了障礙。大聲笑 – kash101
這是沒有問題的，只是讓基本工作和添加功能（或方法調用），因爲你得到每一步工作。現在你應該擺脫它的大部分（至少在這裏），併發佈一個錯誤發生地點的例子。那究竟出了什麼問題。 – jeroen
