1、webform (注意：name后面一定要加[]号)
<form method="post" enctype="multipart/form-data" action="http://127.0.0.1/mobile/public/api/wx/user/upload" >First name: <input type="file" name="file[]" /><br />First name: <input type="file" name="file[]" /><br />Last name: <input type="text" name="token" /><br /><input type="submit" value="提交" /></form>
注：HTML５的文件已经支持多文件上传：
<input type="file" name="file[]" multiple/>
2、后端处理
1 /*上传文件到服务器*/ 2public function uploadFile(\Illuminate\Http\Request $request) 3{ 4 5 $this->validate($request,array('token'=>'required|string')); 6 $this->validationUser($uid,$this->authService); 7 if($request->hasFile('file')) { 8 $root = $request->server('DOCUMENT_ROOT'); 9 $file = $request->file('file');10 //return var_dump($file);11 $filePath=[]; // 定义空数组用来存放图片路径12 foreach ($file as $k => $v) {13 // 判断图片上传中是否出错14 if (!$v->isValid()) {15 $this->apiReturn("上传图片出错，请重试！",1);16 }17 //此处防止没有多文件上传的情况18 if(!empty($v)){19 if ($v->getSize() / 1024 > 600)20 return $this->apiReturn("请检查您上传的文件不能大于600KB", '1');21 $fileName = strtolower($v->getClientOriginalName());22 if (!preg_match('/\.(jpg|jpeg|png|gif)$/', $fileName))23 return $this->apiReturn("您只能上传通用的图片格式", '1');24 $destinationPath = '/mobile/resources/uploads/' . date('Ymd');25 $fileExtendName = substr($fileName, strpos($fileName, '.'));26 $realPath = $root . $destinationPath;27 if (!file_exists($realPath))28 mkdir($realPath);29 $newFileName = uniqid() . mt_rand(1, 100000) . $fileExtendName;30 $v->move($realPath, $newFileName);31$filePath[]=$destinationPath . '/' . $newFileName;32 }}33 return $this->apiReturn(json_encode($filePath), 0);34 }35 else36 return $this->apiReturn('请选择文件再上传', 1);37}
原生多文件上传：
/*多文件上传*/public function uploadImg($file_name,$dir,$format='string'){$file = $_FILES[$file_name];if($file) {$root =$_SERVER['DOCUMENT_ROOT'];$filePath=[]; // 定义空数组用来存放图片路径$fileNumber=count($file['name']);for($i=0;$i<$fileNumber;$i++) {//此处防止没有多文件上传的情况if(!empty($file['name'][$i])){if ($file['size'][$i] / 1024 > 600){return ['error'=>"请检查您上传的文件不能大于600KB"];}$fileName = strtolower($file['name'][$i]);if (!preg_match('/\.(jpg|jpeg|png|gif)$/', $fileName)){return ['error'=>'您只能上传通用的图片格式'];}$destinationPath = $dir. date('Ymd');$fileExtendName = substr($fileName, strpos($fileName, '.'));$realPath = $root . $destinationPath;if (!file_exists($realPath)){make_dir($realPath);}$newFileName = uniqid() . mt_rand(1, 100000) . $fileExtendName;move_uploaded_file($file['tmp_name'][$i], $realPath.'/'.$newFileName);$filePath[]=$destinationPath . '/' . $newFileName; }}if($format=='string')return implode(',',$filePath);}elsereturn ['error'=>'请选择文件再上传'];}
