Hi,
I'm trying top set my very first captcha with the helper.
I'm supposed to tell CI where is my Captcha's images but... I really don't know!
I also wathed videos on youtube where peolple use this images but where I can download or how can I create it?
Actually if I run my script I just have the "image missing" typical warning from the browser but the code I generate seems good...
This is the controller:
Code:
function index()
{
/**
* --SQL DDL
*
* CREATE TABLE captcha (
* captcha_id bigint(13) unsigned NOT NULL auto_increment,
* captcha_time int(10) unsigned NOT NULL,
* ip_address varchar(16) default '0' NOT NULL,
* word varchar(20) NOT NULL,
* PRIMARY KEY `captcha_id` (`captcha_id`),
* KEY `word` (`word`)
* );
*/
$captcha_result = '';
$data["cap_img"] = $this -> _make_captcha();
if ( $this -> input -> post( 'submit' ) ) {
if ( $this -> _check_capthca() ) {
$captcha_result = 'GOOD';
}else {
$captcha_result = 'BAD';
}
}
$data["cap_msg"] = $captcha_result;
$this -> load -> view( 'testcaptcha_view', $data );
}
function _make_captcha()
{
$this -> load -> helper( 'captcha' );
$vals = array(
'img_path' => './captcha/', // PATH for captcha ( *Must mkdir (htdocs)/captcha )
'img_url' => 'captcha/', // URL for captcha img
'img_width' => 200, // width
'img_height' => 60, // height
// 'font_path' => '../system/fonts/2.ttf',
// 'expiration' => 7200 ,
);
// Create captcha
$cap = create_captcha( $vals );
// Write to DB
if ( $cap ) {
$data = array(
'captcha_id' => '',
'captcha_time' => $cap['time'],
'ip_address' => $this -> input -> ip_address(),
'word' => $cap['word'] ,
);
$query = $this -> db -> insert_string( 'captcha', $data );
$this -> db -> query( $query );
}else {
return "Umm captcha not work" ;
}
return $cap['image'] ;
}
function _check_capthca()
{
// Delete old data ( 2hours)
$expiration = time()-7200 ;
$sql = " DELETE FROM captcha WHERE captcha_time < ? ";
$binds = array($expiration);
$query = $this->db->query($sql, $binds);
//checking input
$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time > ?";
$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
$query = $this->db->query($sql, $binds);
$row = $query->row();
if ( $row -> count > 0 )
{
return true;
}
return false;
}
