<!DOCTYPE html><html><head> <title>上传图片</title></head><body><form method="post" action="{{url('uploadImgs')}}" enctype="multipart/form-data"> {{csrf_field()}} <input type="file" name="filename[]"><br/> <input type="file" name="filename[]"><br/> <input type="file" name="filename[]"> <button type="submit">上传图片</button></form></body> |
记得路径那改成post
然后就是后台代码
到config/filesystem.php下增加一个

// 单张图片 public function uploadImg(Request $request){ if ($request->hasFile('filename')) { $postPics = $request->file('filename'); foreach ($postPics as $k => $v) { $extension = $v->extension(); $rule = ['jpg', 'png', 'gif', 'jpeg']; if (!in_array($extension, $rule)) { return '图片格式需要为jpg,png,gif格式'; } $dir = date('ymd'); $fileName = time() . mt_rand(1, 999) .

// 上传图片第二种方式(form表单直接传过来)public uploadImg(){ $image = $_FILES["photo"]["tmp_name"]; $fp = fopen($image, "r"); $file = fread($fp, $_FILES["photo"]["size"]); //二进制数据流 //保存地址 $imgDir = './Uploads/'; //要生成的图片名字 $filename = date("Ym")."/".md5(time().mt_rand(10, 99)).".png"; //新图片名称 $newFilePath = $imgDir.$filename; $data = $file; $newFile = fopen($newFilePath, "w"); //打开文件准备写入 fwrite($newFile, $data); //写入二进制流到文件 fclose($newFile); //关闭文件} |
希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
