首先先看下效果圖
這是添加的時候 可以上傳照片
這是編輯的時候 可以修改照片
代碼部分:
先看控制器:
/***

* @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
*/
public function add()
{
$data = null;
return _view('admin.merchant.merchant.edit', compact('data'));
}
/***

*/
public function store(StoreMenchantRequest $request)

//判斷手機號是否重復 重復不能添加
//后面開發(fā)可能會去掉這個判斷
$merchant = Merchant::where('mobile', $request->mobile)->first();
if (!empty($merchant)) {
return back()->withErrors('該用戶已存在');
}
$token = str_random(60);

];
//上傳縮略圖
$input = $request->all();
if (isset($input['file']) is_object($input['file'])) {

if (!$file_name) {

}
這邊封裝了一個上傳圖片的方法,調(diào)用即可
**
* 調(diào)用的文件中需要 use Illuminate\Support\Facades\Input; Illuminate\Support\Facades\Storage;
* save_image_file 保存圖片文件 ,存在Storage::disk('uploads') 目錄下
* @var $file object 上傳的圖片文件,具體是在 request 中的 UploadedFile 類型的對象
* @var $prefix_name string 可選保存的文件名前綴
* @var $path string 文件路徑
* @return bool/string 如果通過驗證 則返回在新的文件名
*/
if (!function_exists('save_image_file')) {
function save_image_file($file, $prefix_name = '', $path = 'serve')
{
$file = isset($file) ? $file : null;
if ($file != null $file->isValid()) {
// 獲取文件相關信息
$originalName = $file->getClientOriginalName(); // 文件原名
$ext = $file->getClientOriginalExtension(); // 擴展名
//dd($ext);
$file->getClientOriginalName();
if ($ext == "" $file->getClientOriginalName() == 'blob') {
$ext = 'png';
}
if (!preg_match('/jpg|png|gif$/is', $ext)) {
return false;
}
//dd($file->getRealPath());
$realPath = $file->getRealPath(); //臨時文件的絕對路徑
$type = $file->getClientMimeType(); // image/jpeg
// 上傳文件
$filename = $prefix_name . '-' . date('Y-m-d-H-i-s') . '-' . uniqid() . '.' . $ext;
//dd($filename);
$bool = Storage::disk($path)->put($filename, file_get_contents($realPath));
if (!$bool) return false;
return $filename;
}
return false;
}
}
接下來是編輯時候 顯示已經(jīng)上傳的圖片 并且可以進行修改:
