Error with Font and imagettfbbox

Posted on 16th Feb 2014 07:03 pm by admin

I keep getting an error that says "Warning: imagettfbbox() [function.imagettfbbox]: Could not find/open font in /home/a6079442/public_html/rebuild/includes/csi.php on line 48
Error in imagettfbbox function"

I am trying to include a captcha image in this form, and it just doesn't seem to be working. I've got csi.php included on FormToEmail.php

url: http://inferium.site11.com/rebuild/contactform.php

Here is my code for the form page:

Code: <?php

print_r($_POST);
session_start(); //check the captcha

if(!empty($_SESSION['sc'])&&$_SESSION['sc']==$_POST['sc']){unset($_SESSION['sc']); print 'captcha is right';} else {$valCheck=false;$appMessage='Sorry, you have provided an invalid security code';}
?>

Also, here is the code to csi.php:

Code:<?php

session_start();

class csi

public $font = 'mf.ttf';

public function generateCode($characters)
{
/* list all possible characters, similar looking characters and vowels have been removed */
$possible = '23456789bcdfghjkmnpqrstvwxyz';
$code = '';
$i = 0;
while ($i < $characters)
{
$code .= substr($possible, mt_rand(0, strlen($possible)-1), 1);
$i++;
}
return $code;
}

public function csi($width='120',$height='40',$characters='6')
{
$code = $this->generateCode($characters);

/* font size will be 75% of the image height */
$font_size = $height * 0.75;
$image = @imagecreate($width, $height) or die('Cannot initialize new GD image stream');

/* set the colours */
$background_color = imagecolorallocate($image, 255, 255, 255);
$text_color = imagecolorallocate($image, 20, 40, 100);
$noise_color = imagecolorallocate($image, 100, 120, 180);

/* generate random dots in background */
for( $i=0; $i<($width*$height)/3; $i++ )
{
imagefilledellipse($image, mt_rand(0,$width), mt_rand(0,$height), 1, 1, $noise_color);
}
/* generate random lines in background */
for( $i=0; $i<($width*$height)/150; $i++ )
{
imageline($image, mt_rand(0,$width), mt_rand(0,$height), mt_rand(0,$width), mt_rand(0,$height), $noise_color);
}

/* create textbox and add text */
$textbox = imagettfbbox($font_size, 0, $this->font, $code) or die('Error in imagettfbbox function');
$x = ($width - $textbox[4])/2;
$y = ($height - $textbox[5])/2;

imagettftext($image, $font_size, 0, $x, $y, $text_color, $this->font, $code) or die('Error in imagettftext function');

/* output captcha image to browser */
header('Content-Type: image/jpeg');
imagejpeg($image);
imagedestroy($image);
$_SESSION['sc'] = $code;
}

}

$width = isset($_GET['w']) ? $_GET['w'] : '120';
$height = isset($_GET['h']) ? $_GET['h'] : '40';
$characters = isset($_GET['chr']) && $_GET['chr'] > 1 ? $_GET['chr'] : '6';
$captcha = new csi($width,$height,$characters);

?>

Any help with this would be much appreciated
