$szukaj_slowo = 'SELECT * FROM slowa WHERE slowo='.$slowo.'';
$wyslij_zapytanie = $connect->query($szukaj_slowo);
$pobierz_wartosc = $wyslij_zapytanie->fetch_assoc();
$szukaj_slowo_wynik = $pobierz_wartosc['slowo'];
    $connect->close(); 
    if( $szukaj_slowo_wynik == NULL || $szukaj_slowo_wynik == "" )
    {
        Header('Location: index.php');
    }

I take $slowo from form, but if $slowo is empty then i got a fatal error

Fatal error: Call to a member function fetch_assoc() on boolean in C:\xampp\htdocs\error_spr\wyszukaj.php on line 16
