【问题描述】：
我尝试在帖子中创建多张图片上传，但是当我尝试对数组中的元素进行计数时，计数函数经常出错。对于单个图像，如果我删除该数组并计数，则代码可以正常工作。 Lumen 最新版本，PHP 版本 7.3 但我将其降级为 7.1。
代码：
<?php
class PostController extends Controller {
public function __construct() {
$this->middleware('auth');
}
public function index() {
return Auth::user()->post;
}
public function show($post_id) {
$post = Post::findOrFail($post_id);
if (Auth::user()->id !== $post->user_id) {
return response()
->json(['status' => 'error', 'message' => 'unauthorized'], 401);
}
return $post;
}
public function store(Request $request) {
$post = new Post;
$post->setConnection('mysql1');
$user = User::where('token', $request->token)
->first();
if ($user) {
$post1 = $post->create(['post_id' => rand() , 'title' => $request->title, 'cooked_time' => $request->cooked_time, 'user_id' => $request->token, 'location' => $user['name'], 'dispose_time' => strtotime('+01 hours', strtotime($request->cooked_time)) , 'food_type' => $request->food_type, 'description' => $request->description, 'serve_quantity' => $request->serve_quantity, 'lat' => $request->lat, 'long' => $request->long, ]);
$post = Post::where('user_id', $request->token)
->orderBy('id', 'DESC',)
->limit('1')
->get();
if ($request->hasFile('image')) {
// $image_array = [];
$image_array = $request->file('image');
$array_len = count($image_array);
for ($i = 0;$i < $array_len;$i++) {
$image_size = $image_array[$i]->getClientSize();
$image_ext = $image_array[$i]->getClientOriginalExtension();
$new_image_name = rand(123456, 99999999) . "." . $image_ext;
if (!function_exists('public_path')) {
/**
* Return the path to public dir
*
* @param null $path
*
* @return string
*/
function public_path($path = null) {
return rtrim(app()->basePath('public/' . $path) , '/');
}
}
$destination_path = public_path('/images');
$image_array[$i]->move($destination_path, $new_image_name);
$image = new PostImage;
$images->image_name = $new_image_name;
$images->post_id = $post1['post_id'];
$images->save();
}
}
return response()
->json(['message' => 'success', 'user' => $user['name'], 'post' => $post1, ], 200);
}
}
public function update(Request $request, $post_id) {
$post = Board::find($post_id);
if (Auth::user()->id !== $post_id->user_id) {
return response()
->json(['status' => 'error', 'message' => 'unauthorized'], 401);
}
$post->update($request->all());
return response()
->json(['status' => 'success', 'post' => $post], 200);
}
public function destroy($id) {
$post = Post::find($post_id);
if (Auth::user()->id !== $post->user_id) {
return response()
->json(['status' => 'error', 'message' => 'unauthorized'], 401);
}
if (Post::destroy($id)) {
return response()->json(['status' => 'success', 'message' => 'Post Deleted Successfully'], 200);
}
return response()
->json(['status' => 'error', 'message' => 'Something Went Wrong']);
}
}
【问题讨论】：
-
@karel 我正在使用文本编辑器，如果有任何意外的括号或错误，它会通知我
-
@karel 但这并没有给我带来问题，当我尝试传递图像时，问题在于计数功能
-
表单是什么样子的？您目前正在寻找
$request->file('image')这似乎不是一个数组。也许您的表单应该看起来像<input type="file" class="form-control" name="images[]" ..>。对您的$request->file('image')执行 var_dump 以检查您收到了哪些数据。 -
@BertMaurau 我只是在创建 API 我没有通过邮递员制作我正在测试的前端

@BertMaurau 我只是在创建 API 在你对 var_dump 说我试过之后我没有通过邮递员测试我的前端，这就是我得到的对象（Illuminate\Http\UploadedFile）#89 (7) { ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=> bool(false) }
