上面是写好的类,写完后发现..只支持多文件上传,但是哩表单的name后面给[]还是可以的.

下面是写多文件上传前的单文件上传代码

var_dump(upload("myfile","./b/",array("jpg","gif","png","zip","rar"),10000000,true));function upload($inputName,$path,$fileType,$maxSize,$isRandName){if(empty($_FILES[$inputName])){$fileMsg['error']="没有上传任何文件";return $fileMsg;}//上传目录不存在就创建if (!file_exists($path)) {if(!@mkdir($path,0755)){$fileMsg['error']="上传目录不存在并且创建失败！";return $fileMsg;}}//echo "<pre>";//var_dump($_FILES[$inputName]);//echo "</pre>";$fileMsg['name']=$_FILES[$inputName]['name'];if($_FILES[$inputName]['error'] > 0){switch ($_FILES[$inputName]['error']) {case 1:$msg = "上传文件大小超出了php配置文件中的约定值: upload_max_filesize";break;case 2:$msg = "上传文件大小超出了表单中的约定值: MAX_FILE_SIZE";break;case 3:$msg = "文件只有部分被上载";break;case 4:$msg = "没有上传任何文件";break;default:$msg = "未知错误 错误码:".$error;break;}$fileMsg['error'] = $msg ;return $fileMsg;}if ($_FILES[$inputName]['size'] > $maxSize) {$fileMsg['error'] = "文件大小超过自定义设置的限定值" ;return $fileMsg;}$hz=explode('.', $_FILES[$inputName]['name']);$hz=$hz[count($hz)-1];if (!in_array($hz,$fileType)) {$fileMsg['error'] = "不允许上传的文件类型" ;return $fileMsg;}if (!is_uploaded_file($_FILES[$inputName]['tmp_name'])) {$fileMsg['error'] = "不是通过http post上传的" ;return $fileMsg;}//设置上传的文件名$newFileName = $isRandName ?   date("YmdHis").rand(100,999).'.'.$hz :   $_FILES[$inputName]['name'] ;$newFilePath =  $path.$newFileName;if (!move_uploaded_file($_FILES[$inputName]['tmp_name'],$newFilePath)) {$fileMsg['error'] = "上传的文件移动失败" ;return $fileMsg;}$fileMsg['name']    =  $_FILES[$inputName]['name'];$fileMsg['newName'] =  $newFileName;$fileMsg['size']    =  $_FILES[$inputName]['size'];$fileMsg['path']    =  $newFilePath;//$fileMsg['error']   =  "";return $fileMsg;}

还有一个是写多文件上传类的时候写的单个函数,

echo "<pre>";var_dump(uploads("my","./b/",array("jpg","gif","png","zip","rar"),10000000,true));echo "</pre>";function uploads($inputName,$path,$fileType,$maxSize,$isRandName){//上传目录不存在就创建if (!file_exists($path)) {if(!@mkdir($path,0755)){$fileMsg['error']="上传目录不存在并且创建失败！";return $fileMsg;}}$name=$_FILES[$inputName]['name'];$tmp_name=$_FILES[$inputName]['tmp_name'];$size=$_FILES[$inputName]['size'];$error=$_FILES[$inputName]['error'];$fileMsg=array();if(is_array($name)){$return=true;for ($i=0; $i < count($name); $i++) { $_fileMsg['name']=$name[$i];$_fileMsg['error']=fileError($error[$i]);if ($size[$i] > $maxSize) {$_fileMsg['error'] = "文件大小超过自定义设置的限定值" ;}$hz=explode('.', $_fileMsg['name']);$hz=$hz[count($hz)-1];if (!in_array($hz,$fileType)) {$_fileMsg['error'] = "不允许上传的文件类型" ;}if (!is_uploaded_file($tmp_name[$i])) {$_fileMsg['error'] = "不是通过http post上传的" ;}$fileMsg[]=$_fileMsg;if ($_fileMsg['error']!='') {$return=false;}}if (!$return) {return $fileMsg;}else{for ($i=0; $i < count($name); $i++) { $hz=explode('.', $name[$i]);$hz=$hz[count($hz)-1];$newFileName = $isRandName ?   date("YmdHis").rand(100,999).'.'.$hz :   $name[$i]['name'] ;$newFilePath =  $path.$newFileName;if (!move_uploaded_file($tmp_name[$i],$newFilePath)) {$fileMsg[$i]['error'] = "上传的文件移动失败" ;}//$fileMsg[$i]['name']    =  $name[$i];$fileMsg[$i]['newName'] =  $newFileName;$fileMsg[$i]['size']    =  $size[$i];$fileMsg[$i]['path']    =  $newFilePath;}return $fileMsg;}}}function fileError($error){if($error > 0){switch ($error) {case 1:$msg = "上传文件大小超出了php配置文件中的约定值: upload_max_filesize";break;case 2:$msg = "上传文件大小超出了表单中的约定值: MAX_FILE_SIZE";break;case 3:$msg = "文件只有部分被上载";break;case 4:$msg = "没有上传任何文件";break;default:$msg = "未知错误 错误码:".$error;break;}return $msg;}return '';}
