Error: Typed Property Must Not be Accessed Before Initialisation

Level 10

How are you sending the data? Have you tried dumping the $request to see if the values are being sent as expected?

ddd($request);

This is creating a new instance of 'child', which will have nothing in it yet:

$request->child_id = new child;
$request->status = new child;

Possibly access the request data like so:

$request->input('child_id');
$request->input('status');

@RayC Thanks for that. dd($request) does not work on XHR data. Although I did give it a try.

$request->input('child_id');
$request->input('status');

gave me an error 500.

Cheers,

RayC

@vincej How are you sending the data? Format, JSON?

RayC

See: https://laravel.com/docs/9.x/requests#retrieving-json-input-values

Level 10

@vincej Do not use Vue but I assume it sends data via JSON, if this is the case you need to change your content-type to:

application/json

Currently it is set to

text/html

@vincej You should buy Spatie Ray. It will dump to the ray application irrespective of where the dump occurs.

@vincej hi Vince. Good to see you. What error are you getting from

$request->input('child_id');
$request->input('status');

These two alone shouldn't give any errors

@Sinnbeck Hi Rene! Ok, I will elaborate a little over the answer I gave @rayc .

when I apply this code below I get two different but related errors. Take note of Line 58 marked:

the Console Error

500 internal server error.

Chrome dev tools / XHR / Preview

exception: "Error" file: "/Users/vincejacobs/Sites/KidsClub/app/Http/Controllers/Children.php" line: 58 message: "Typed property Illuminate\Http\Request::$child_id must not be accessed before initialization"

public function upDateChild(Request $request)
    {
        $request->input('child_id');       		// Line 58
        $request->input('status');

        DB::table('child')
            ->where('child_id', $request->child_id)
            ->update(['status' => $request->status]); 
}

Level 102

@vincej it might be due to you manually changing the request. This code does not make much sense for me

$request->child_id = new child;
$request->status = new child;

The request class does not have a built in child_id, so you much be doing something :) https://github.com/laravel/framework/blob/5.5/src/Illuminate/Http/Request.php

Can you perhaps show the complete class?

Level 15

It does not make any sense to me either. I only stuck it in there following some other LC posts dealing with the same error. Putting aside the obvious problem being discussed, the mystery is that my dev machine is a mirror image of my production machine. Everything works fine on production.

My Production code

public function upDateChild(Request $request)
    {
        DB::table('child')
            ->where('child_id', $request->child_id)
            ->update(['status' => $request->status]);

        $now = Carbon::now()->format('Y-m-d');

        $count = DB::table('attendance')
            ->select('date')
            ->where('date', '=', $now)
            ->count();

        if ($count > 0) {
            DB::table('attendance')
                ->insert(['child_id' => $request->child_id, 'timeIn' => 'absent', 'date' => $now, 'created_at' => Carbon::now(), 'updated_at' => Carbon::now()]);
        }
    }

@vincej can you try deleting your vendor folder and run composer install?
