Post Multiple files with GuzzleHttp Client

Guzzle is a PHP HTTP Client for sending HTTP requests to APIs. But sending multiple files with a single request sometimes bring on a lot of complexity and people get confused in sending arrays of data within an array for a multipart form, quite confusing.

This snippet will explain how to send multiple files or images with a single request through Guzzle HTTP client with ease. So let's dive straight in the code.

$output = [];
      foreach ( $images['image'] as $key => $value ) {
         if ( ! is_array( $value ) ) {
            $output[] = [
               'name'     => 'image[]',
               'contents' => fopen( $value->getPathname(), 'r' ),
               'filename' => $value->getClientOriginalName()
            ];
            continue;
         }
      }

      $output [] =
         [
            'name'     => 'field_name',
            'contents' => \request()->get( 'field_name' )
         ];

      $output [] = [
         'name'     => 'field_name_2',
         'contents' => \request()->get( 'field_name_2' )
      ];
      $output [] = [
         'name'     => 'field_name_3',
         'contents' => \request()->get( 'field_name_3' )
      ];

$client = new Client( [
   'base_uri'    => "http://api_url.dev/",
] );

 $response = $client->request( 'POST', 'api/endpoint', [
 'headers' => [
 'Authorization' => $token
 ],
 'multipart' => $output

 ] );

 $data = \GuzzleHttp\json_decode( $response->getBody() );
