laravel5.5的上傳圖片（僅傳到伺服器端）
阿新 • • 發佈：2019-01-23
這裡麵包含單張和多張圖片的上傳
首先先來前端頁面的html
<!DOCTYPE html> <html> <head> <title>上傳圖片</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">上傳圖片</button> </form> </body>
記得路徑那改成post
然後就是後臺程式碼
到config/filesystem.php下增加一個
'upload' => [
'driver' => 'local',
'root' => 'uploadImages'
],
use Illuminate\Http\Request;
// 單張圖片 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 '圖片格式需要為jpg,png,gif格式'; } $dir = date('ymd'); $fileName = time() . mt_rand(1, 999) . ".jpg"; $storeResult = $v->storeAs('filename', $dir . "/" . $fileName, 'upload');// 預設儲存位置是要到filesystem.php設定，儲存到storage/app/.. $outPut[] = [ 'img_url' => "images/" . $storeResult, 'uid' => $uid, 'exam_id' => $examId, 'question_id' => $questionId, ]; } DB::table('x2_upload_img')->insert($outPut); echo "寫到資料庫了，圖片上去了只是ide載入很慢"; } else { exit('未獲得到上傳檔案，或上傳失敗'); }
// 多圖上傳 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 '圖片格式需要為jpg,png,gif格式'; } $storeResult = $v->storeAs('filename','201810/test1.jpg','upload');// 預設儲存位置是要到filesystem.php設定，儲存到storage/app/.. $outPut[] = [ 'extension' => $extension, 'store_result' => $storeResult ]; } echo "<pre>"; print_r($outPut);die; } exit('未獲得到上傳檔案，或上傳失敗'); }
// 上傳圖片第二種方式(form表單直接傳過來)
public uploadImg(){
$image = $_FILES["photo"]["tmp_name"];
$fp = fopen($image, "r");
$file = fread($fp, $_FILES["photo"]["size"]); //二進位制資料流
//儲存地址
$imgDir = './Uploads/';
//要生成的圖片名字
$filename = date("Ym")."/".md5(time().mt_rand(10, 99)).".png"; //新圖片名稱
$newFilePath = $imgDir.$filename;
$data = $file;
$newFile = fopen($newFilePath, "w"); //開啟檔案準備寫入
fwrite($newFile, $data); //寫入二進位制流到檔案
fclose($newFile); //關閉檔案
}
有空來補七牛的。。
