How to pass variable to addButtonFromView

[smzapp]

Using laravel backpack, I created a custom blade file named bulk_send_order. Now, When I passed posts, $posts is undefined in blade. I am using "backpack/crud": "^6.7". How to fix this?

CRUD::addButtonFromView(
'bottom', // stack
'bulk_send_order', // button name
'bulk_send_order', // Blade view name
'end', // position
[ 'posts' => \App\Models\Post::all() ] // data
);
// blade

-- Select Location -- @foreach($posts as $post) {{ $post->title}} @Endforeach

In Backpack 6.x, the standard signature for CRUD::addButtonFromView() does not support passing additional variables directly to the Blade view as a fifth parameter. The method expects only four parameters: stack, name, view, and position. This is why your $posts variable is undefined in the Blade file.

However, starting from Backpack v6.7, you can pass parameters to a button view using the fluent button API with the parameters() method. Here’s how you can do it:

CRUD::button('bulk_send_order')
    ->stack('bottom')
    ->view('bulk_send_order')
    ->position('end')
    ->parameters(['posts' => \App\Models\Post::all()]);

In your Blade file (resources/views/vendor/backpack/crud/buttons/bulk_send_order.blade.php), you should access the variable via the $parameters array:

<select class="form-select form-control">
    <option value="">-- Select Location --</option>
    @foreach($parameters['posts'] as $post)
        <option value="{{ $post->id }}">{{ $post->title }}</option>
    @endforeach
</select>

This approach is supported in recent versions of Backpack 6.x, as described in the CRUD buttons can now pass parameters to views update.

Summary:

• Use the fluent button API and the parameters() method to pass data to your button view.
• Access the data in the Blade file via the $parameters array, not as a direct variable.

If you use the classic addButtonFromView() method, there is no built-in way to pass extra variables to the view in Backpack 6.x¹.

Hey @smzapp

It seems you are trying to build a BulkOperation and want to show dropdown in the modal or something.
Here you don't need to pass anything. You can get data within the button view like this:

@php
    $posts = \App\Models\Post::all();
@endphp

<select class="form-select form-control">
    <option value="">-- Select Location --</option>
    @foreach($posts as $post)
        <option value="{{ $post->id }}">{{ $post->title }}</option>
    @endforeach
</select>
