    script per generazioni immagini probblemi di funzionamento

    Ciao
    ho trovato questo script di esempio per generare immagini attraverso del codice php.

    Pultroppo non sono molto brava con il codice......... 😢 e ho riscontrato qualche difficoltà.

    Il testo originale era questo:

    <?php
/* form.php
Click Captcha Ver.1

//buffer
ob_start('ob_gzhandler');
session_start();

// if submit
if (($_POST[x])&&(substr($_SESSION[igif], 17) === $_SESSION['afloat'])){

// posted
$x = $_POST[x];

// you can remove 4 lines below they are for demo
$fname = strip_tags($_POST[fname]);
$lname = strip_tags($_POST[lname]);
$fname = stripslashes(substr($fname, 0, 12));
$lname = stripslashes(substr($lname, 0, 12));
// you can remove 4 lines above they are for demo

// decode, strip string and round numbers
$a = base64_decode($_SESSION['afloat']);
$b = 0 + $a;
$a = explode(" ", $a);
$a = $a[3];
$bb = round($b);
$aa = round($a);

// x coords
$gc = explode(" ", '0 19 40 60 82 104 79 100 121 142 163 185');

// check if correct number has been clicked
$ac = $aa + 6;
if ($bb <= $aa){ $ac = $bb + 1; }

//demo wrong number clicked error message below
$mess = "ERROR: Sorry " . stripslashes($fname . "_" . $lname) . " wrong number clicked";
// if correct number clicked success
if (($x >= $gc[$ac-1]) && ($x <= $gc[$ac])){
// submit your form

//demo SUCCESS message below
$mess = "SUCCESS: Yes " . stripslashes($fname . "_" . $lname) . " correct number clicked";
}

//demo alert message below
?>
<script>
alert("<?=$mess;?>");
window.location = window.location;
</script>
<?
session_unset();
session_destroy();
ob_end_flush();
exit;
}
// afloat = base64_encoded random string
$afloat = base64_encode(" " . $num1 = rand(0,3) . "." . $num2 = rand(100,999) . "
 Float " . $num3 = rand(1,4) . "." . $num4 = rand(100,999) . "  ");

// rectangle x coord

$aler = "> 78";
if(round($num1 . "." . $num2) <= round($num3 . "." . $num4)) {$aler = "< 105";}

// create random image
$_SESSION[igif] = "create_gif.php?a=" . $afloat . "";
$_SESSION['afloat'] = $afloat;

Ma come potete vedere voi stessi la pagina non funziona come dovrebbe, non viene carricata nessuna immagine.  :x:x:x ho fatto numerosi tentavi ma senza risultato.

Poi vorrei che cliccando sul tasto il tutto fosse inviato a questa pagina  http://www.designgrouparchitetti.it/contattami2.php 
????????? vi chiedo un aiutino per finire queste due pagine.



Vi mando anche il link ai due esempi che ho scaricato, magari ho saltato qualcosa per questo non funzionano:

http://www.designgrouparchitetti.it/form.php
http://www.designgrouparchitetti.it/create_gif.php

Grazie a tutti

    Allora ho modificato qualcosina.....
    l'immagine si vede, viene generata corretamente.

    adesso però non capisco una cosa.
    Quando clicco sopra l'immagine corretta non succede niente..........

    e poi non rieco a far si che tutti i dati del form una volta confermata l'immagine corretta, vengano inviati ad un'altra pagina.
