<button type="submit" style="background-color: #4CAF50; border: none; color: white; padding: 15px 32px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px;">Publizieren</button>
</div>
</form>

My PostController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Post;
class PostController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
//
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
//
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
Post::create([
'title'->request('title'),
'text'->request('text'),
'hashtags'->request('hashtags'),
'bild'->request('bild'),
'mp3'->request('mp3')
]);
return redirect('/dashboard');
}
/**
* Display the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function edit($id)
{
//
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
//
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function destroy($id)
{
//
}
}
My Post Model:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
protected $fillable = [
'userid',
'title',
'text',
'hashtags',
'bild',
'mp3',
];
}
My web.php routes:
<?php
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
return view('welcome');
});
Route::get('/dashboard', function () {
return view('dashboard');
})->middleware(['auth', 'verified'])->name('dashboard');
Route::get('/create', function () {
return view('create');
})->middleware(['auth', 'verified'])->name('create');
Route::get('/generator', function () {
return view('generator');
})->middleware(['auth', 'verified'])->name('generator');
Route::post('/posts', 'App\Http\Controllers\PostController@store')->middleware(['auth', 'verified']);
require __DIR__.'/auth.php';
On submitting form, the error "Call to a member function request() on string" occurs Is it a wrong syntax in the controller or does it relate to something else? How should i write the controller differently?
What am i doing wrong?
CodePudding user response：
The problem is going to be 'title'->request('title') (and all the similar lines below it). 'title'-> means you're trying to call a function on 'title' which is clearly a piece of text and therefore doesn't have any functions.
If you're trying to create an associative array, where "title" is a key and the value comes from the request data, then
=>is the syntax to assign a value to a keyYou need
$in front of "request", so PHP knows you're trying to access that variable, and$requestwill be an object itself, so you need to use->to denote access to its functions, not(and).
Post::create([
'title' => $request->input("title"),
'text' => $request->input("text"),
'hashtags' => $request->input("hashtags"),
'bild' => $request->input("bild"),
'mp3' => $request->input("mp3")
]);
I think you've got confused between the syntax for calling a function on an object, and syntax for creating and accessing arrays.
Relevant documentation: https://www.php.net/manual/en/language.types.array.php
CodePudding user response：
You are using a wrong syntax for array:
Post::create([
'title'->request('title'),
'text'->request('text'),
'hashtags'->request('hashtags'),
'bild'->request('bild'),
'mp3'->request('mp3')
]);
Do this instead
Post::create([
'title' => $request->input('title'),
'text' => $request->input('text'),
'hashtags' => $request->input('hashtags'),
'bild' => $request->input('bild'),
'mp3' => $request->input('mp3')
]);
That should fix your issue. But Since your form field names match your table columns you can use a simpler method:
Post::create($request->input());
And, Do not forget to add validation.
