HTTP Client Multipart with multidimensional array inputs

[omzy]

• Laravel Version: 8.37.0
• PHP Version: 7.3.13
• Database Driver & Version: MySQL 5.7.32

Description:

The fix applied in #32058 does not work for multidimensional array inputs.

Steps To Reproduce:

HTML:

<form method="post" action="" enctype="multipart/form-data">
    <input type="text" name="data[Product][user_id]">
    <input type="text" name="data[Product][supplier_id]">
    <input type="file" name="file">
</form>

PHP:

public function index(Request $request)
{
    $url = 'my-url';
    $post_data = $request->post();

    // Example of how $post_data will look
    $post_data = [
        'data[Product][user_id]' => 123,
        'data[Product][supplier_id]' => 456,
    ];

    $contents = fopen($request->file('file'), 'r');

    return Http::attach('file', $contents)
        ->post($url, $post_data);
}

This produces an error: A 'contents' key is required.

A print_r() of $laravelData (line 714 src/Illuminate/Http/Client/PendingRequest.php) outputs the following:

Array
(
    [0] => Array
        (
            [Product] => Array
                (
                    [user_id] => 123
                    [supplier_id] => 456
                )
        )

    [1] => Array
        (
            [name] => file
            [contents] => Resource id #439
        )
)

As you can see, it does not format the input variables into name and contents pairs, like it has done with the file input.

In the meantime, I have used the code in this answer here to reformat the POST array: https://stackoverflow.com/a/53731825/372630

It would be great if we could integrate something like this in to the library, as the error isn't helpful and it took me a while to figure out the problem.

[omzy]

Any potential solution would need to take in to account:

• POST array containing a mixture of standard inputs and multidimensional array inputs
• POST array containing a numerically indexed array, e.g:

<input type="text" name="data[categories][]" value="1">
<input type="text" name="data[categories][]" value="2">

This is definitely happening:

use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\File;

$path = storage_path('file.txt');

Http::acceptJson()
    ->attach('attachments[]', File::get($path), File::basename($path))
    ->post($destination, [
        'name' => 'John Smith',
        'providers' => [1,2,3]
]);

with throw InvalidArgumentException with message 'A 'contents' key is required'
where as will be just fine

Http::acceptJson()
    ->attach('attachments[]', File::get($path), File::basename($path))
    ->post($destination, [
        'name' => 'John Smith',
        'providers' => '1'
]);
