    How to Check if an Attachment Exists

    • To check whether a document contains a certain attachment,
      use the session.advanced operations attachments.exists method.

    • Calling exists does not load the document or the attachment to the session, and the session will not track them.

    • In this page:

    Check if attachment exists 

    $exists = $session
    ->advanced()
    ->attachments()
    ->exists("categories/1-A", "image.jpg");

    if ($exists)
    {
        // attachment 'image.jpg' exists on document 'categories/1-A'
    }

    Syntax 

    function exists(?string $documentId, ?string $name): bool;
    Parameter Type Description
    $documentId ?string The ID of the document you want to check
    $name ?string The name of the attachment you are looking for
    Return Value Description
    bool true - The specified attachment exists for this document
    false - The attachment doesn't exist for the document
