本文实例讲述了laravel5.5框架的上传图片功能。分享给大家供大家参考,具体如下:

这里面包含单张和多张图片的上传

首先先来前端页面的html


<!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


'upload' => [
 'driver' => 'local',
 'root' => 'uploadImages'
 ],


use Illuminate\Http\Request;


// 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) . ".jpg";
 $storeResult = $v->storeAs('filename', $dir . "/" . $fileName, 'upload');// 默认保存位置是要到filesystem.php设置,保存到storage/app/..
 $outPut[] = [
 'img_url' => "images/" . $storeResult, 'uid' => $uid, 'exam_id' => $examId, 'question_id' => $questionId,
 ];
 }
 DB::table('x2_upload_img')->insert($outPut);
 echo "写到数据库了,图片上去了只是ide加载很慢";

 } else {
 exit('未获得到上传文件,或上传失败');
 }


// 多图上传
public function uploadImgs(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';
 }
 $storeResult = $v->storeAs('filename','201810/test1.jpg','upload');// 默认保存位置是要到filesystem.php设置,保存到storage/app/..

 $outPut[] = [
 'extension' => $extension,
 'store_result' => $storeResult
 ];
 }
 echo "<pre>";
 print_r($outPut);die;
 }
 exit('未获得到上传文件,或上传失败');
}


// 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
}
