Ciao
ho trovato in questo sito web tra gli esempi questo script 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:
Codice:
e la pagina per generare immagini che porta questo codice:codice:<?php /* form.php Click Captcha Ver.1 Created on: 4/17/2007 by Ron Hickey http://6tx.net/sc */ //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 .

Ma come potete vedere voi stessi la pagina non funziona come dovrebbe, non viene carricata nessuna immagine. ho fatto numerosi tentavi ma senza risultato.
Poi vorrei che cliccando sul tasto il tutto fosse inviato a questa pagina contatti
????????? 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:
Pagina script
Pagina immagine
Grazie a tutti
