[/code]
But what is the code:
require_once ( "securimage / securimage.php");
Get the picture session, is the only way?
I was thinking about this solution. But I do not work.
[code]
codigo=$valor;
}
}
?>
[/code]
I do not want to be in doubt please.
how would the script of "securimage.php"
And in the "single source" (the ED) would take the value in this way?
[code]
require_once("securimage.php");
$securimage= new Securimage(); //Instance sht securimage object.
$securimage->codigo;
[/code]]]>http://community.xajaxproject.org/user/3957/2009-07-16T02:24:53Zhttp://community.xajaxproject.org/post/28408/#p28408<![CDATA[Re: Captcha]]>http://community.xajaxproject.org/user/934/2009-06-08T20:06:20Zhttp://community.xajaxproject.org/post/28192/#p28192<![CDATA[Re: Captcha]]>check($captcha_code) === false)

See if this fits your need.
