    [2.0]Flex Guestbook con AMFPHP 1.9

    Questo è un piccolo esempio sul funzionamento delle librerie amfphp 1.9...il codice è chiaro e per qualsiasi probleema sono a disposizione...
    Quest'esempio lo avevo gia postato su infernet...ma magari puo tornare utile a qualcuno...

    l'esempio si trova qui:

    ***************
```o qui:

    
E ora per chi fosse interessato posto i sorgenti:

la pagina php avrà il seguente codice:

 [php] <?

class Fgb{

//lettura db
function getMsgs(){
$fd='<dati>';

if(!$dbc=mysql_connect('xxx','xxx','xxx')){return 'SqlError: '.mysql_error();}

if(!mysql_select_db('myDB',$dbc)){return 'Database not found.';}

if(!$res=mysql_query('SELECT * FROM tabella')){return 'Error: '.mysql_error();}

$i=0;
while($rst=mysql_fetch_array($res)){
$fd.='<ogg><nid>'.$rst[ID].'</nid><author>'.$rst[author].'</author>
<imgurl>'.$rst[imgurl].'</imgurl><msg>'.$rst[msg].'</msg></ogg>';
$i++;
}

$fd.='<nm>'.$i.'</nm></dati>';

mysql_free_result($res);
mysql_close($dbc);

return $fd;

}
//aggiunta post
function addMsg($au,$im,$ms){
if(!$dbc2=mysql_connect('xxx,'xxx','xxx)){return 'SqlError: '.mysql_error();}

if(!mysql_select_db('myDB',$dbc2)){return 'Database not found.';}

$q=sprintf("INSERT INTO tabella VALUES('',%s,%s,%s)",$this->quote_smart((string)$au),
$this->quote_smart((string)$im),
$this->quote_smart((string)$ms));

$rs=mysql_query($q);
mysql_close($dbc2);

return $rs;
}

//funzione Da Adobe
function quote_smart($value)
{

if (get_magic_quotes_gpc()) {
$value = stripslashes($value);
}

if (!is_numeric($value)) {
$value = "'" . mysql_real_escape_string($value) . "'";
}
return $value;
}
}

?>  [/php]codice semplice non occorrono spiegazioni...

PS per usare amfphp dovete scaricare la cartella contenente le librerie da sourceforge e metterla sul vostro dominio poi compilare il .swf con il parametro:

 Codice:

-services "services-config.xml"

  

ah se non funziona l'esempio è perchè  avrete 
superato il limite di queries sul database standard di altervista...
provate l'ora successiva!!!
e se c'è qualche problema con gli url di destinazione negli mxml è per il fatto che ho dovuto troncarli perche non sono ìutente premium' ...
 
spero possa interessare a qualcuno ciao
