Calling a class function in blade view laravel-CodePudding

I have a CartController with the following function:

  public function getTotalCartPrice()
    {
        $totalCartPrice = 1;
        
        return $totalCartPrice;
    }

Cart.blade.php

<h3 >Cart total: {{ Cart::getTotalCartPrice }} </h3>

Routes

Route::resource('/cart', CartController::class);

Using this does not seem to display the total cart price and I get an error saying class "Cart" not found. I have attempted to change my route to this:

Route::get('/cartPrice', [CartController::class, 'getTotalCartPrice'])->name('getTotalCartPrice');

and then inside my blade view:

<h3 >Cart total: {{ route('getTotalCartPrice') }} </h3>

But I just get an output on the website:

Cart total: http://localhost/cartPrice

To fix this error and display the total cart price, you can do the following:

In your CartController, add the Cart class to the use statement:

use Cart;

public function getTotalCartPrice()
{
    $totalCartPrice = 1;
        
    return $totalCartPrice;
}

In your blade view, you need to call the function using () after the function name:

<h3 >Cart total: {{ Cart::getTotalCartPrice() }} </h3>

In your routes file, you can use the resource method to create routes for the CartController class and its methods:

Route::resource('/cart', CartController::class);

In your blade view, you can use the route helper function to generate the URL for the getTotalCartPrice route and call the function using () after the function name:

<h3 >Cart total: {{ route('cart.getTotalCartPrice')() }} </h3>

After making these changes, the total cart price should be displayed on the website.

I'm trying to help you.

To fix this error, you should add static keyword to function getTotalCartPrice in CartController. So it will be :

public static function getTotalCartPrice()
{
    $totalCartPrice = 1;
    
    return $totalCartPrice;
}

After that, in your view (blade) you should add Cart class in the top of the code. In this case I assume that your Cart controller class name is Cart, so the example is :

@php
    use App\Http\Controllers\Cart;
@endphp
// the rest of blade code

After that, you have to add () when you call the function from your blade

<h3 >Cart total: {{ Cart::getTotalCartPrice() }} </h3>

After that, the total cart must be shown.
