Project: bookable activity
Error: Undefined variable $days
Description: creating mini-eshop which you can choose if you want to go for riding, doing arts or do guided tour. User have to choose 3 of the activities by choosing time and day which are inserted manually at database managment.
More error details: at https://flareapp.io/share/Bm0jQD07#F47
Update: According to your ideas i take off getDates() and use the getIndex() by doing that
public function getIndex()
{
$products = Product::all();
$days = DB::table('days')->pluck("day","id");
return view('shop.index',compact('days'), ['products' => $products]);
}
and found the variable $days but not times.
web.php
//use db;
Route::get('product.index','ProductController@getDates');
Route::get('product.index/gettimes/{id}','ProductController@getTimes');

CodePudding user response：
While looking at the code for Controller...
You are calling getDates method of ProductsController which opens the index.blade.php inside shops folder in resources...
public function getDates() // shop.index needs both $products and $days
{
$days = DB::table('days')->pluck("day","id");
return view('shop.index',compact('days')); // No Products sent..
}
Index has $product ... so when u open the index page from getDates method it wont have the $products variable...
public function getIndex() // shop.index needs both $products and $days
{
$products = Product::all();
return view('shop.index', ['products' => $products]); // no Days sent.
}
Both the variables $days and $products are needed in the shop.index template in shops folder.
secondly, opening a route that would call the index method of the ProductController would open the shop.index template but won't find the $days variable as it is not being sent in the Index function of ProductsController.
CodePudding user response：
So the stack trace provided by you at https://flareapp.io/share/Bm0jQD07#F47 shows that your error is occurring on line 24 of your ProductController and is due to you trying to use a variable $days which you’ve neither declared nor initialised:
return view('shop.index', ['products' => $products], ['days' => $days]);
You need to declare and initialise the $days variable to resolve the error.
For example:
public function getIndex()
{
$days = Day::all();
$products = Product::all();
return view('shop.index', ['products' => $products, 'days' => $days]);
}
