form post action into php var

Im in this page: website.php?page=5 and in this page I have this form:

<form method="POST" action="website.php?page=<?php echo $pagenumber; ?>">
        <input type="text" name="goto" />
        <input type="submit" name="submit" value="goto" />
</form>

If I write something like 3 into the text field and press the goto button (if isset.... my php code get the number and upload into the $pagenumber var)

But the new page isn't the website.php?page=3 what I want. The new page is website.php?page= (there is no number) .and if I press again then goes it to the right page.

I think in the first press when i do the $pagenumber isn't declared. Only when i press second.

How can I fix it? I must use this way i cant use session, cookie etc.

                <?php if(isset($_POST['submit']))
                {
                    $kitkeresek = $_POST['goto'];
                                $becsuletemw = "SELECT * FROM adatok WHERE nev = '$kitkeresek'";
                            $becsuletem2w = mysql_query($becsuletemw);
                            while( $becsuletem3w = mysql_fetch_array($becsuletem2w))
                            $becsuletemw = $becsuletem3w["becsulet"];

                    $valllamiw = mysql_query("SELECT  becsulet FROM adatok WHERE becsulet > '$becsuletemw' ");
                    $rowsw = mysql_num_rows( $valllamiw );
                    $kitkeresekw = $rowsw + 1 ;
                    $intvizsgalat= $kitkeresekw/10;
                        if (is_int($intvizsgalat))  
                                { $pagenumber = $intvizsgalat - 1 ; }  
                            else  
                                {$pagenumber = floor($kitkeresekw/10); } ; 
                } 
            ?>

When you do this :

$intvizsgalat= $kitkeresekw/10;

$intvizsgalat is float, even if the result is int, because it is the result of a division.

You can try var_dump($intvizsgalat) to confirm

try something like this:

$floatParts = $intvizsgalat - floor(intvizsgalat);
if ($floatParts == 0) {
//
} else { 
//
}
