    <?php
    function upload_multi($path,$photo,$i){
    $uploaddir = './'.$path;//文件存放目錄
    if(!file_exists($uploaddir))//如果目錄不存在就新建
    $uploaddir=mkdir($uploaddir);
    $piece = explode('.',$photo['name'][$i]);
    $uploadfile = $uploaddir . '/'.md5($piece[0]).'.'.$piece[1];
    $result = move_uploaded_file($photo['tmp_name'][$i], $uploadfile);
    if(!$result){
    exit('上傳失敗');
    }
    return basename($uploadfile);
    }
    if($_POST['tijiao']){
    extract($_POST);
    $i=0;
    foreach ($_FILES["pictures"]["error"] as $key => $error) {
    if ($error == UPLOAD_ERR_OK) {
    upload_multi($email,$_FILES["pictures"],$i);
    }
    $i++;
    }
    }
    ?>
    <script language="javascript">
    function go_up(){
    document.getElementById('new_up').innerHTML+='<input type="file" name="pictures[]" /><br>';
    }
    </script>
    <form action="index.php" method="post" enctype="multipart/form-data">

    <input type="file" name="pictures[]" /><br>
    <div id="new_up"></div>
    <input type="button"" name="add_img" value="新增上傳" onclick="go_up()"/><br>
