How to update dynamic input fields with radio buttons in Laravel?

To update dynamic input fields with radio buttons in Laravel, you can follow these steps:

1. Include a radio button on your form for each dynamic input field. For example, if you have a list of products with a quantity input field for each product, you can include a radio button for each product as well.
2. Use JavaScript to listen for changes on the radio buttons and update the corresponding input fields accordingly. When a radio button is selected, you can retrieve the index or a unique identifier from the radio button's value and use this to dynamically update the corresponding input field.
3. In your Laravel controller, handle the form submission and update the database with the new values for the dynamic input fields. You can retrieve the values of the input fields using the request object and update your database accordingly.
4. Finally, you can return a success message or redirect the user to a success page after the data is successfully updated in the database.

Here's a basic example of how you can achieve this in your Laravel application:

1. Update your form to include radio buttons and corresponding input fields:

1
2
3
4

@foreach($products as $product)
    <input type="radio" name="selected_product" value="{{ $product->id }}">{{ $product->name }}<br>
    <input type="text" name="quantity[{{ $product->id }}]" value="{{ $product->quantity }}"><br>
@endforeach

1. Use JavaScript to listen for changes on the radio buttons and update the corresponding input fields:

1
2
3
4
5
6

$('input[name="selected_product"]').change(function() {
    var productId = $(this).val();
    var quantity = $('input[name="quantity[" + productId + "]"]').val();
    
    // Update input fields based on the selected product
});

1. In your controller, handle the form submission and update the database:

7

public function update(Request $request) {
    foreach($request->input('quantity') as $productId => $quantity) {
        Product::where('id', $productId)->update(['quantity' => $quantity]);
    }
    
    return redirect()->route('products.index')->with('success', 'Products updated successfully');
}

This is a basic example and you may need to modify it based on your specific requirements. Feel free to customize it further to suit your needs.
