<!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

foreach ($postPics as $k => $v) {

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');
}

// 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。
