Sprawdzanie poprawności mime dla przesyłania pliku php nie działa

Question

Próbuję sprawdzić typ pliku MIME, zanim prześlę go do bazy danych. Jednak nie otrzymuję żadnych wyników z mojego programu. Czy ktoś może mi w tym pomóc? Z góry dzięki :)

kodu uchwyt Form (handleUpload.php)

<?php 
    if (isset($_POST['submit'])) { 
     $Upload = new Upload(); 
     if (function_exists("check_doc_mime")) { 
      //validate MIME type 
      $validateMime = $Upload->check_doc_mime($_FILES['filename']['tmp_name']); 
      if (!$Upload->check_doc_mime($validateMime)) { 
       /* Not a MIME type we want on our site, stop here 
       * and return an error message, or just die(); */ 
       echo "Mime not what we want."; 
      } else { 
       echo "This is okay"; 
      } 
     } 
    } 
?> 

Funkcje i kod manipulacji danych (upload.php)

Answer 1

Okazuje się, że to dlatego, że nie napisać jeśli instrukcja jest poprawna. To powinno być if (!$validateMime) {, a nie if (!$Upload->check_doc_mime($validateMime)) {.
