Laravel 从具有相同列的两个表中检索数据

Question

I hope this is not duplicated.

I have two tables in first table (users) there is column (uid and tokenn) the ids of registered users. When a guest from outside website sends a message to (uid) , a function posts the message to (posts table) and column (uid) turns to (to_id) in posts table.

I want to get the (tokeen) of the (to_id) which is (uid) in users table in order to let Firebase push notification to that token.

users table:

id	uid	name	email	password	tokenn
5	6	o	o	o	12313

Posts table:

id	pid	from_id	to_id	feedback
5			6	12313

My postsController.php

 <?php namespace App\\Http\\Controllers; use Illuminate\\Http\\Request; use App\\post; use Auth; use Lang; class postsController extends Controller { public function send_feedback(Request $request){ $this->validate($request,[ 'feedback_image' => 'nullable|image|mimes:jpeg,png,jpg|max:3072', 'feedback_content' => 'required|max:500' ]); $pid = rand(9,999999999)+time(); if (Auth::user()) { $from_id = Auth::user()->uid; }elseif (Auth::guest()) { $from_id = 0; } $to_id = $request['hidden2']; $feedback = $request['feedback_content']; $image = $request->file('feedback_image'); $time = $request['hidden']; if ($request->hasFile('feedback_image')) { $img_ext = $image->getClientOriginalExtension(); $img_name = rand(9,9999999)+time()+rand(0,55555).".".$img_ext; $img_new = $image->storeAs("fbImgs",$img_name); }else{ $img_name = ""; } $post = new post(); $post->pid = $pid; $post->from_id = $from_id; $post->to_id = $to_id; $post->feedback = $feedback; $post->image = $img_name; $post->time = $time; $post->save(); // define('API_ACCESS_KEY','xxx'); $fcmUrl = 'https://fcm.googleapis.com/fcm/send'; $token = User::where('uid', $to_id)->first()->tokenn; $notification = [ 'title' =>'xxx', 'body' => 'xxx', 'icon' =>'myIcon', 'sound' => 'mySound' ]; $extraNotificationData = ["message" => $notification,"moredata" =>'dd']; $fcmNotification = [ //'registration_ids' => $tokenList, //multple token array 'to' => $token, //single token 'notification' => $notification, 'data' => $extraNotificationData ]; $headers = [ 'Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json' ]; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$fcmUrl); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fcmNotification)); $result = curl_exec($ch); curl_close($ch); // return redirect()->back()->with('feedback_sent',Lang::get('trans.fb_sent')); } public function postPrivacy(Request $request){ $pid_var = $request['pid']; $pid_ex = explode("_", $pid_var); $pid = @$pid_ex[1]; if ($request['status'] == "true") { $updatePrivacy = post::where('pid',$pid)->update(['privacy' => 1]); }else{ $updatePrivacy = post::where('pid',$pid)->update(['privacy' => 0]); } return $pid; } public function deletePost(Request $request){ $checkID = post::where('pid',$request['pid'])->get()->count(); if ($checkID > 0) { $allowed = post::where('pid',$request['pid'])->get(); foreach ($allowed as $getAllowed) { $to_id = $getAllowed->to_id; $from_id = $getAllowed->from_id; } if ($to_id == Auth::user()->uid || $from_id == Auth::user()->uid) { $deleteFB = post::where('pid',$request['pid'])->delete(); return "done"; }else{ return Lang::get('trans.delPost_notAllowed'); } }else{ return Lang::get('trans.err_somethingWrong'); } } }

I tried to retrieving the token of the recipient of the message as follows:

 $token=Auth::user()->tokenn; //but it returns the logged in and the sender user's token which is wrong.

 $token = User::find($to_id)->tokenn; $token = User::where('uid', $to_id)->first()->tokenn; //these both are not working too

I need to Retrieving the token of the recipient When A GUEST sends a message to any.

Hope I'm clear.

You must Create User.php in your models directory

this class by default created when you install laravel, but if you delete it unintentionally you can create it by:

php artisan make:model User

and in your Controller you must use this model instead of App\\Http\\Controllers\\User .

so In other words you must use App\\User in laravel 7 and below or use App\\Models\\User in laravel 8 in your Controller like below.

use App\User; // if your laravel version is 7 or below

use App\Models\User; // if your laravel version is 8 or higher
