What is the most effective approach for managing two distinct ajax calls within a Laravel application?

I am working on a page with two separate ajax calls (using Laravel). The first call triggers the second one, but the options for the second ajax are in a select box. Here is my current solution:

 public function getCategoryAjax(Request $request)
{
    $product = Product::where('category_id',$request->get('category_id'))->get();

    return $product;
}
public function getPriceAjax(Request $request)
{
    $withPrice = Product::where('category_id',$request->get('category_id'));
    if ($request->get('price') == 1){
        $withPrice=$withPrice->where('min_price','<', 1000000)->get();
    }elseif ($request->get('price') == 2){
        $withPrice=$withPrice->where('min_price','>', 1000000)->andWhere('max_price','<',2000000)->get();
    }

    return $withPrice;
}

The first method handles the first ajax call, while the second method uses an if-else statement to handle the options from the select box.

My question is, is there a more efficient way to accomplish this? https://i.sstatic.net/3PN8t.png (The select box on the left is used for the second ajax call)

Answer №1

When it comes to managing multiple if conditions in the getPriceAjax(Request $request) function, there is a more efficient approach that can be taken...

If you are facing this issue, consider structuring your code as follows:

// Define all price range rules in an array for easy modification
protected $priceRules = array(
    1 => ["0", "1000000"],
    2 => ["1000000", "2000000"],
    3 => ["2000000", "3000000"],
    4 => ["3000000", "4000000"],
    // Add more rules as needed
);

public function getPriceAjax(Request $request) {
    $price = $request->get('price');
    
    // Validate if the given option exists in the array
    if (isset($this->priceRules[$price])) {
        // Dynamically handle the query based on the selected price option
        $withPrice = Product::where('category_id', $request->get('category_id'))
                            ->whereBetween('price', $this->priceRules[$price])
                            ->get();
        return $withPrice;
    }
    
    return 'error';
}

I hope this solution proves helpful to you.
