$designer = designer::where('name', $designer_name)->firstOrCreate(
['name' => $designer_name], ['slug' => $designer_slug]
);
$designer->name = $designer_name;
$designer->slug = $designer_slug;
$designer->save();
$designer_id = $designer->id;
$product = new Product;
$product->title = $request->title;

$product->slug = $product_slug;
$product->user_id = Auth::user()->id;
$product->published_at = Carbon::now()->format('Y-m-d');
if($request->hasFile('image')) {
$file = Input::file('image');
//getting timestamp
$timestamp = str_replace([' ', ':'], '-', Carbon::now()->toDateTimeString());
$name = $timestamp. '-' .$file->getClientOriginalName();
$file->move(public_path().'/images/product/', $name);
$product->image = $name;
$thumb = Image::make(public_path().'/images/product/' . $name)->resize(1200,1800)->save(public_path().'/images/product/thumb/' . $name, 90);
}
$product->save();
$productsearch = product::where('slug', $product_slug)->firstorfail();
$product_id = $productsearch->id;
$categoryname = $request->category;
foreach ($categoryname as $name) {
$category = category::firstOrNew(['name' => $name]);
$category->designer_id = $designer_id;
$category->save();
$category->products()->attach($product_id);
}
return Redirect::back()->with('status', 'Post Success');
missing is product need designerid
designer need category_id
category need product_id
how to solve this on controller thank you

Answer 1

You can't update the designer_id column in that way unless you've added designer_id to the fillable array in your model.
Alternatively, you can use the Eloquent methods by simply doing $product->designer()->associate($designer); instead of $product->designer_id = $designer->id.
If you haven't already, you'll also need to setup a relationship on the Product model.
public function designer() {
return $this->belongsTo(Designer::class, 'designer_id');
}
