I've just written a class around the PEAR captcha code.
Except, I can't get it to work.
The code is included:
$this->phrase = '';
$this->image = '';
$this->width = '';
$this->height = '';
$this->path = $PATH;
$this->error = '';
function GenerateCaptcha($width, $height, $options=false)
if ( !$options ) $this->GenerateCaptchaOptions($options);
$captcha = TEXT_CAPTCHA::factory('Image');
$result = $captcha->init($width, $height, null, $options);
if ( PEAR::isError($captcha) )
return ($this->error = CAPTCHA_CREATE_ERROR);
$this->phrase = $captcha->getPhrase( );
$this->image = $captcha->getCAPTCHAAsJPEG( );
if ( PEAR::isError($this->image) )
return ($this->error = CAPTCHA_IMAGE_ERROR);
$this->width = $width;
$this->height = $height;
function WriteCaptcha( )
$file = $this->path . md5($this->phrase) . '.jpg';
function GetCaptchaFilename( )
return md5($this->phrase) . '.jpg';
$options = array( 'font_size' => 32,
'font_path' => './',
'font_file' => 'arial.ttf'
As far as I can tell, its unable to write/create the file/image.
[29-Aug-2007 18:34:09] There was an error creating the captcha image
Is what I am getting in my PHP logs. Now the captcha directory is chmod 777, just to see if that
fixed it. It didn't. I also did a chown apache:blah captcha and that didn't work either.
The code I'm using to call the CAPTCHA is:
$captchaObject = new Captcha(CAPTCHA_PATH);
if ( $captchaObject->error != '' )
$captchaObject->GetCaptchaFilename( ), 300, 180, 'CAPTCHA'));
Now, if I print_r($captchaObject) I get:
[error] => There was an error creating the captcha image
[phrase] => chiaprae
[image] => PEAR_Error Object
[mode] => 1
[level] => 1024
[message] => Error initializing Image_Text (font missing?!)I just copied this from the PEAR Apress book. Does anyone know where to get the font file,if that is indeed the error?- Ben
