php文件上传与多文件上传其它没有多大的区别,多文件上传只是我们把表单名改成数组形式,而获取利用foreach遍历就可以实现多文件上传了,动态多文件上传只要在js加一个动态增加多文件上传框,同样在php处理时就遍历一下数组就成了.
最简单的实例如下,代码如下:
- <form action="" method="post" enctype="multipart/form-data">
- <p>Pictures:
- <input type="file" name="pictures[]" />
- <input type="file" name="pictures[]" />
- <input type="file" name="pictures[]" />
- <input type="submit" value="Send" />
- </p>
- </form>
- <?php
- foreach ($_FILES["pictures"]["error"] as $key => $error) {
- if ($error == UPLOAD_ERR_OK) {
- $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
- $name = $_FILES["pictures"]["name"][$key];
- move_uploaded_file($tmp_name, "data/$name");
- }
- }
- ?>
下面分享其它朋友的例子,代码如下:
- <?php
- //filename:multi_upload.php
- if($ifupload)
- {
- $path=AddSlashes(dirname($PATH_TRANSLATED))."/upload/";
- for($i=1;$i<=8;$i++)
- {
- $files="afile".$i;
- if(${$files}!="none")
- {
- if(copy(${$files},$path.${$files."_name"}))
- {
- }
- }
- }
- print "<b>You have uploaded files successfully</b><br>";
- print "<a href="multi_upload.php">Return</a>";
- exit;
- }
- ?>

如果我们要动态不确定性的多文件上传怎么实现下面也有实例,代码如下:
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
- <title>文档上传</title>
- </head>
- <body>
- <script language="javascript"><!--
- 动态添加文件选择控件-->
- function AddRow()
- {
- var eNewRow = tblData.insertRow();
- for (var i=0;i<1;i++)
- {
- var eNewCell = eNewRow.insertCell();
- eNewCell.innerHTML = "<tr><td><input type='file' name='filelist[]' size='50'/></td></tr>";
- }
- }
- // --></script>
- <form name="myform" method="post" action="uploadfile.php" enctype="multipart/form-data" >
- <table id="tblData" width="400" border="0">
- <!-- 将上传文件必须用post的方法和enctype="multipart/form-data" -->
- <!-- 将本页的网址传给uploadfile.php-->
- <input name="postadd" type="hidden" value="<?php echo "http://".$_SERVER['HTTP_HOST'].$_SERVER["PHP_SELF"]; ?>" />
- <tr><td>文件上传列表
- <input type="button" name="addfile" onclick="AddRow()" value="添加列表" /></td></tr>
- <!-- filelist[]必须是一个数组-->
- <tr><td><input type="file" name="filelist[]" size="50" /></td></tr>
- </table>
- <input type="submit" name="submitfile" value="提交文件" />
- </form>
- </body>

提交文件代码:
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">

- <title>文件上传结果</title>
- </head>
- <body>
- <?php
- if ($_POST["submitfile"]!="")
- {
- $Path="./".date('Ym')."/";
- if (!is_dir($Path))//创建路径
- { mkdir($Path); }
- echo "<div>";
- for ($i=0;$i<count($filelist);$i++)
- { //$_FILES["filelist"]["size"][$i]的排列顺序不可以变,因为fileist是一个二维数组
- if ($_FILES["filelist"]["size"][$i]!=0)
- {
- $File=$Path.date('Ymdhm')."_".$_FILES["filelist"]["name"][$i];
- if (move_uploaded_file($_FILES["filelist"]["tmp_name"][$i],$File))
- { echo "文件上传成功 文件类型:".$_FILES["filelist"]["type"][$i]." "."文件名:"
- .$_FILES["filelist"]["name"][$i]."<br>"; }
- else
- { echo "文件名:".$_FILES["filelist"]["name"][$i]."上传失败</br>"; }
- }
- }
- echo "</div><br><a href="$postadd" href="$postadd">返回</a></div>";
- }
- ?>
- </body>
- </html>
另:错误信息说明
从 PHP 4.2.0 开始,PHP 将随文件信息数组一起返回一个对应的错误代码,该代码可以在文件上传时生成的文件数组中的 error 字段中被找到,也就是 $_FILES['userfile']['error']。
UPLOAD_ERR_OK
其值为 0,没有错误发生,文件上传成功.
UPLOAD_ERR_INI_SIZE
其值为 1,上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值.
UPLOAD_ERR_FORM_SIZE
其值为 2,上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值.UPLOAD_ERR_PARTIAL
其值为 3,文件只有部分被上传.
UPLOAD_ERR_NO_FILE
其值为 4,没有文件被上传.
UPLOAD_ERR_NO_TMP_DIR
其值为 6,找不到临时文件夹。PHP 4.3.10 和 PHP 5.0.3 引进.
UPLOAD_ERR_CANT_WRITE
其值为 7,文件写入失败。PHP 5.1.0 引进.
注意:以上值在 PHP 4.3.0 之后变成了 PHP 常量.
