php 文件上传问题

复制代码 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <?php /*  * Created on 2010-3-30  *  * To change the template for this generated file go to  * Window - Preferences - PHPeclipse - PHP - Code Templates  * 文件上传 */ if(isset($_POST['submit'])) {     $upfile=@$_FILES["upfile"];     $name=$upfile["name"];     $uptype=pathinfo($name,PATHINFO_EXTENSION);//上传文件类型     //echo $uptype;     $name=mktime().".".$uptype;     $type=$upfile["type"];     $tmp_name=$upfile["tmp_name"];     $error=$upfile["error"];     $size=$upfile["size"];     $path="../upload/";     switch($type) {         case "application/octet-stream":             $ok=1;             break;         case "application/pdf":             $ok=1;             break;         case "application/msword":             $ok=1;             break;     }     if(@!$ok) {         $tishi= "你上传的文件类型非法";     }else {         if(is_uploaded_file($upfile["tmp_name"])) {             move_uploaded_file($tmp_name,$path.$name);             $tishi= "上传成功";         }     } } ?> <script type="text/javascript"> parent.form_fox.file.value = "<?php echo $path.$name;?>";//这个把路径传给父窗口的一个文本框里 </script> <form action="" method="post" enctype="multipart/form-data">     <input type="file" name="upfile"/>     <input type="submit"name="submit" value="上传"/> <?php echo $tishi;?>     </form>

这个是upfile.php上传文件的.

复制代码  <form name="form_fox" onSubmit="return checkinput()" method="post" action="newsadd.php">                             <tr>                                 <td colspan="2" class="red">发布资料,技术文档,产品说明!!!</td>                             </tr>                             <tr>                                 <td width="80" align="center"><span class="left_txt2">资料标题：</span></td>                                 <td><input id="topic6" size="31" name="title" class="button01" />                                     <span class="red">*</span></td>                             </tr>                             <tr>                                 <td align="center"><span class="left_txt2">资料类别：</span></td>                                 <td><span class="left_txt">                                         <select name="c_id" id="c_id">                                             <?php                                             $query=$link->read_mysql("p_newsclass","where f_id=0 and lang='ch'");                                             while($row=mysql_fetch_array($query)) {                                                 $dalei[$row["id"]]=$row["name"];                                                 echo "<option value='".$row['id'].",".$row['f_id']."'>".$row['name']."</option>";                                                 $id=$row['id'];                                                 $query2=$link->read_mysql("p_newsclass","where f_id=$id");                                                 while($row=mysql_fetch_array($query2)) {                                                     echo "<option value='".$row['id'].",".$row['f_id']."'>┠".$row['name']."</option>";                                                 }                                             }                                             ?>                                         </select>                                         <span class="red">*</span></span></td>                             </tr>                             <tr>                                 <td align="center"><span class="left_txt2">文件上传：</span></td>                                 <td>                                     <iframe src="../common/upfile.php" name="ww" width="500" height="35" scrolling="No" frameborder="0" id="ww"></iframe>                                     <input type="text" name="file" id="file"/>//接收路径                                 </td>                             </tr>                             <tr>                                 <td align="center"> </td>                                 <td><input class="submit_button" border="0" name="I5" type="submit" value="确认发布" />                                     <input  size="15" name="key" class="button01" value="add" type="hidden" /></td>                             </tr>                         </form>

现在就是这个,在父窗口中接收不到路径,报错
'700')this.width='700';if(this.offsetHeight>'700')this.height='700';" title="Click Here To EnLarge">

你先试试直接返回路径，然后看看能正常放回吗？
还可以看下比较好的程序设计，借鉴下。
