很简单的一个小例子 jQuery Mobile + PHP 通过超全局 $_FILES 上传,然后用move_uploaded_file()方法把上传的图片移动到到本地服务器下的文件夹,

下面是html和php的代码

复制代码 代码如下:<!DOCTYPE html><html><head>                <meta charset = "utf-8">                <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css">                <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>                <script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script></head><body>        <div data-role="page" id="upload" >               <div data-role="header"  >                                <h1>校园祭</h1>                                <a href="#pageone" data-rolr = button data-icon="home" class="ui-btn-left" >首页</a>                </div>                <div data-role="content" >                <form action="upload_file.php" method="post" enctype="multipart/form-data" data-ajax="false">                                <input  id="uploadimg" name="file"  type="file"  runat="server" method="post"                                                enctype="multipart/form-data" data-inline="true"  data-ajax="false" />                                 <center><button  data-inline="true"  >上传</button></center>                </form>                </div>                <div data-role="footer" data-position="fixed" data-fullscreen="true">                                <h1>创新实验</h1>                </div>       </div></body></html>

复制代码 代码如下:<?php         if ($_FILES["file"]["error"] > 0)         {                 echo "Return Code: " . $_FILES["file"]["error"] . "<br />";         }         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("upload/" . $_FILES["file"]["name"]))                 {                         echo $_FILES["file"]["name"] . " already exists. ";                 }                 else                 {                         move_uploaded_file($_FILES["file"]["tmp_name"],                        "upload/".$_FILES["file"]["name"]);                         echo "Stored in: "  ."upload/". $_FILES["file"]["name"];                 }         } } ?>

代码很简单,但是使用过程中却发现一个问题,自己试了好久都上传不了询问了小伙伴后,发现问题所在是文件权限不足,从而限制了网页上传图片到文件夹中.所以解决办法就是把文件夹的权限问题解决掉.

复制代码 代码如下:$ cd /var/www$ sudo chmod -R  777  html

ok,现在就可以将文件上传到服务器的文件夹了.
