How to add (upload) pictures to the infoblock via postman?
wrote this code:

$targetDir = $_SERVER["DOCUMENT_ROOT"]."/upload/tmp/";
    $allowTypes = array('jpg','png','jpeg','gif');
    $url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://{$_SERVER['HTTP_HOST']}";
    $statusMsg = $errorMsg = $arrPhoto = $errorUpload = $errorUploadType = $arrTmp = [];
    if(!empty(array_filter($_FILES['photo']['name']))) {
        foreach ($_FILES['photo']['name'] as $key => $val) {
            // File upload path
            $fileName = basename($_FILES['photo']['name'][$key]);
            $targetFilePath = $targetDir . $fileName;
            $file_info = $_FILES["photo"]["tmp_name"];

            // Check whether file type is valid
            $fileType = pathinfo($targetFilePath, PATHINFO_EXTENSION);
            echo json_encode($fileType);
            if (in_array($fileType, $allowTypes)) {
                // Upload file to server
                if (move_uploaded_file($_FILES["photo"]["tmp_name"][$key], $targetFilePath)) {
                    $file_info = $_SERVER["DOCUMENT_ROOT"]."/upload/tmp/".$file_info;
                    $prop["photo"]["n".count($prop["photo"])]["VALUE"] = $file_info;
                    $arrPhoto[] = $url . $targetFilePath;
                } else {
                    $errorUpload[] = $_FILES['photo']['name'][$key];
                }
            } else {
                $errorUploadType[] = $_FILES['photo']['name'][$key];
            }
        }
    }

$prop = array(
"photo" => $arrPhoto
);

it is written to a local file, but does not show in the admin panel.
How to load the built-in Bitrix method?
Can you tell me how to upload images via postman?

Answer 1

it is necessary to save the file using Bitrix tools,
my old version:

$file_im = CFile::CheckImageFile($_FILES["PREVIEW_PICTURE"],0,0,0,"IMAGE");
    if (!$file_im) {
      CAllFile::ResizeImage(
        $_FILES["PREVIEW_PICTURE"],
        array(
         "width" => "800",
         "height" => "800"
        ),
        BX_RESIZE_IMAGE_PROPORTIONAL_ALT
        );
      $file_ID = CFile::SaveFile($_FILES["PREVIEW_PICTURE"], "catalog/".$type_object);
    } else {
      $return["error"]["str"] = $file_im;
      exit(\Bitrix\Main\Web\Json::encode($return));
    }
    if ($file_ID) $file_pp = CFile::MakeFileArray($file_ID);

and then you hammer into the desired property of the infoblock, for example PREVIEW_PICTURE, i.e. first you save, the id comes in the response, you get the desired array from it, which you drive into the desired field
