I'm only getting an error while trying to update the data. I'm using post method not the push. I've tried to add @method('PUT') but that didn't work, too.

Creating new category just works fine as it should do but when I try to edit something it just throws the error. Also I tried to use route::put but that didn't work.

My CategoryController.php

<?php

        return view('admin.category.index', [

        ]);

My routes

// Admin category routes

CodePudding user response：

I'd make these modifications to your code: edit.blade:

 <form action="/admin/category/update/{{$data->id}}" method="POST">
 @csrf
 @method('PUT')
 .........

Route:

Route::put('/admin/category/update/{id}', [AdminCategoryController::class,'update'] )->name('admin_category_update');

Check if it works.

One more thing: If you correctly created model binding, your update function could look like this:

public function update(Request $request, Category $category, $id)
{
    //
    $category->parent_id = 1;
    $category->title = $request->title;
    $category->keywords = $request->keywords;
    $category->description = $request->description;
    $category->status = $request->status;
    $category->save();
    return redirect('admin/category');
}

That is because you already have the model right there: public function update(Request $request, **Category $category**, $id)
