Uploading one PDF document

[Larene Spitler]

What is wrong with my code?

$filename = '/home/familysearch/public_html/fst' . $_POST['story_id'] . '.pdf';

$title = str_replace(" ", "+", $_POST['title']); 

$filelink = 'fst' . $_POST['story_id'] . '.pdf';

$url = "https://sandbox.familysearch.org/platform/memories/memories";

$client = new Client();

$response = $client->post($url, [

'headers' => [

'Content-Type' => 'multipart/form-data; boundary=Boundary_5_1593431620_1418337402143',

    'Authorization' => 'Bearer ' . $_POST['access_token'],

    'MIME-Version' => '1.0'

    ],

    'body' => [

        'Content-Type' => 'application/pdf',

        'Content-Disposition' => 'form-data; name="' . $title . '"',

        'pdf_filed' => fopen($filename, 'rb')

    ]

]);
