我最近一直在尝试使用PHP，到目前为止一直很好，直到碰到一堵墙为止。这是我的一小段代码。它允许我上传单个文件，但是我想要的是能够上传多个文件。这是PHP和HTML文件：<html><head> <meta charset="utf-8" /> <title>Ajax upload form</title><script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><script type="text/javascript" src="https://www.google.com/jsapi"></script><script type="text/javascript"> function sendfile(){ var fd = new FormData(); for (var i = 0, len = document.getElementById('myfile').files.length; i < len; i++) { fd.append("myfile", document.getElementById('myfile').files[i]); } $.ajax({ url: 'uploadfile.php', data: fd, processData: false, contentType: false, type: 'POST', success: function(data){ alert(data); } }); } </script></head><body> <form action="uploadfile.php" method="post" enctype="multipart/form-data" id="form-id"> <p><input id="myfile" type="file" name="myfile" multiple=multiple/> <input type="button" name="upload" id="upload" value="Upload" onclick="sendfile()" id="upload-button-id" /></p> </form></body></html>和PHP文件：<?php $target = "uploadfolder/"; //for($i=0; $i <count($_FILES['myfile']['name']); $i++){ if(move_uploaded_file($_FILES['myfile']['tmp_name'], $target.$_FILES['myfile']['name'])) { echo 'Successfully copied'; }else{ echo 'Sorry, could not copy'; } }// ?>任何帮助将不胜感激。
