這裡面包含單張和多張圖檔的上傳
首先先來前端頁面的html
<!DOCTYPE html>
<html>
<head>
<title>上傳圖檔</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">上傳圖檔</button>
</form>
</body>
記得路徑那改成post
然後就是背景代碼
到config/filesystem.php下增加一個
'upload' => [
'driver' => 'local',
'root' => 'uploadImages'
],
use Illuminate\Http\Request;
// 單張圖檔
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 '圖檔格式需要為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，圖檔上去了隻是ide加載很慢";
} 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 '圖檔格式需要為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');
}
// 上傳圖檔第二種方式(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"]); //二進制資料流
//儲存位址
$imgDir = './Uploads/';
//要生成的圖檔名字
$filename = date("Ym")."/".md5(time().mt_rand(10, 99)).".png"; //新圖檔名稱
$newFilePath = $imgDir.$filename;
$data = $file;
$newFile = fopen($newFilePath, "w"); //打開檔案準備寫入
fwrite($newFile, $data); //寫入二進制流到檔案
fclose($newFile); //關閉檔案
}
有空來補七牛的。。
