php怎么一个file上传多张图片？？？？？？？？？

高人 指路。。

<?php

刚不久写的一个文件上传的类！上面已经有说明了，你参考一下，不明白的话，可以问我，或者加入我们的QQ群讨论！

swfupload 可以实现你的功能而且带进度条的 测试地址 http://www.ll96.cn/sufup 下不到的话我可以给你一个

<input type='file' name=file[] size =22> <input type='file' name=file[] size =22> <input type='file' name=file[] size =22> <input type='file' name=file[] size =22> $_FILES['file'][]//他的类型是一个数组。明白原理就简单了。

<?php class upLoad { var $savepath = 'F:/wamp/www/data/'; //file save dir var $saveurl = ' http://127.0.0.1/data/'; var $format = 'jpg,gif,png,tif,bmp'; //Establishment document extension var $maxsize = 5242880; //file size is 5M; var $ext; //extension var $filepath; //file path var $filename = ''; //file name var $fileinfo = array(); //info,他返回上传后的文件路径，URL，名称，大小，扩展名，方便引用 function upLoad($path='',$url='',$maxsize='',$format = '') { if($path != '') { $path = (substr($path, -1) == "/") ? $path : $path.'/'; $this->savepath = $path; } if($url != '') { $url = (substr($url,-1) == '/') ? $url : $url.'/'; $this->url = $url; } $this->maxsize = ($maxsize == '') ? $this->maxsize : $maxsize; $this->format = ($format == '') ? $this->format : $format; } function up_file($form,$filename='') { if(!isset($_FILES[$form])) { emMsg('没有文件可上传'); } if(!is_writable($this->savepath)) { emMsg('所指定的保存文件位置没有写的权限'); } if(is_array($_FILES[$form]['name'])) { for($i = 0; $i<count($_FILES[$form]); $i++) { $tmpinfo = array(); $tmpinfo['name'] = $_FILES[$form]['name'][$i]; $tmpinfo['tmp_name'] = $_FILES[$form]['tmp_name'][$i]; $tmpinfo['size'] = $_FILES[$form]['size'][$i]; $tmpinfo['error'] = $_FILES[$form]['error'][$i]; $this->set_filename('',$tmpinfo); $this->copyfile($tmpinfo); $this->fileinfo[$i]['url'] = $this->url; $this->fileinfo[$i]['name'] = $this->filename; $this->fileinfo[$i]['size'] = $tmpinfo['size']; $this->fileinfo[$i]['ext'] = $this->ext; $this->fileinfo[$i]['path'] = $this->filepath; } } else { $this->set_filename($filename,$_FILES[$form]); $this->copyfile($_FILES[$form]); $this->fileinfo[0]['url'] = $this->url; $this->fileinfo[0]['name'] = $this->filename; $this->fileinfo[0]['size'] = $_FILES[$form]['size']; $this->fileinfo[0]['ext'] = $this->ext; $this->fileinfo[0]['path'] = $this->filepath; } } function copyfile($file) { if($file["size"] > $this->maxsize) { emMsg('文件大小超过限制'); } if(!in_array(strtolower($this->ext), explode(",", strtolower($this->format)))) { emMsg('只能上传反缀名为'.$this->format.'的文件'); } if(is_uploaded_file($file["tmp_name"])) { if(file_exists($this->savepath)) { if(!move_uploaded_file($file["tmp_name"], $this->filepath)) { $errors = array( 0=>"File upload success", 1=>"Upload file Size exceeded the limit value system.", 2=>"Upload files over the size of the HTML form MAX_FILE_SIZE option to specify the value.", 3=>"Only some file were uploaded.

<input type='file' name=file[] size =22> <input type='file' name=file[] size =22> <input type='file' name=file[] size =22> <input type='file' name=file[] size =22>

$_FILES['file']接收

一个file能多张上传吗？
