我想在Laravel中更新图像，但是会引发错误
在字符串上调用成员函数getClientOriginalExtension（）
[25] [22] [27] [33]
[25] [27] [33]
[27] [33]
[33]
函数中的$this->storeImage($ad, 'photo1')似乎不起作用。我首先尝试仅使用一张图像，但无法弄清楚如何使其工作。我尝试在update()方法中执行与在update()方法中相同的操作，但是它不起作用。
AdController.php
store()这是public function store()
{
$ad = new Ad();
request()->validate([
'title' => ['required', 'min:10'],
'description' => 'required',
'guarantee'=>'required',
'city' => 'required',
'address' => 'required',
'rent' => 'required',
'type' => 'required',
'partitioning' => 'required',
'number_of_rooms' => 'required',
'culinary' => 'required',
'phone' => 'required',
'date_available' => 'required',
// 'min_age' => ['min:1', 'max:99'],
// 'max_age' => ['min:1', 'max:99'],
'photo1' => 'required'

}
函数：
storeImage()似乎private function storeImage($ad, $photo){
if(request()->has($photo)) {
$ad->$photo = $ad->title.$ad->date_available.$photo.'.'.request()->$photo->getClientOriginalExtension();
$imageExtensions = ['jpg', 'jpeg', 'gif', 'png', 'bmp', 'svg', 'svgz', 'cgm', 'djv', 'djvu', 'ico', 'ief','jpe', 'pbm', 'pgm', 'pnm', 'ppm', 'ras', 'rgb', 'tif', 'tiff', 'wbmp', 'xbm', 'xpm', 'xwd'];
$foo = \File::extension($ad->$photo);
if(in_array($foo, $imageExtensions))
{
$width = Image::make(request()->$photo)->width();
$height = Image::make(request()->$photo)->height();
$img = Image::make(request()->$photo->getRealPath())
->resize($width/3,$height/3)
->orientate()
->save('images/'.$ad->$photo,40);
}
}
}
在$this->storeImage($ad, 'photo1');方法中不起作用。关于如何更换它的任何想法？我必须改变什么？谢谢！
答案 0 :(得分：0)
首先，可以代替所有的$ad->param = request('param')：
$input = $request->all();
$ad->update($input);
这将使用给定的输入更新$ ad中的所有字段。
或者您甚至可以：
$input = $request->all()
$ad = \App\Models\Ad::updateOrCreate($id, $input);
$add->save();
这将清除您的代码。
