Hi

 

I am using katak support which is a ticket system script and is all installed and working perfect apart from the php captcha is not working on the new ticket page

 

I have been looking it and saw it could be the gd library not installed or enabled, the freetype is not installed or enabled, a file permissions issue or a htaccess issue

 

I have a phpinfo file and says gd library is enabled as well as freetype is enabled, I checked the file permissions and is ok as well as the htaccess file, I even removed the htaccess file and is still the same

 

I don't get it, if I visit the captcha.php file itself in the browser I get a 502 Bad gateway message if it helps but not sure how to fix it

 

I am using php version 5.5.30

 

I am not sure which code to post here to have a look, below is my captcha.php code

<?php

/*********************************************************************
    captcha.php

    Simply returns captcha image.

require_once('main.inc.php');
require(INCLUDE_DIR.'class.captcha.php');

$captcha = new Captcha(5,12,ROOT_DIR.'images/captcha/');
echo $captcha->getImage();
?>

Below is the code from the class.captcha.php file

<?php
/*********************************************************************
    class.captcha.php

    Very basic captcha class.

class Captcha {
    var $hash;
    var $bgimages=array('cottoncandy.png','grass.png','ripple.png','silk.png','whirlpool.png',
                        'bubbles.png','crackle.png','lines.png','sand.png','snakeskin.png');
    var $font = 10;
    function Captcha($len=6,$font=7,$bg=''){

        $this->hash = strtoupper(substr(md5(rand(0, 9999)),rand(0, 24),$len));
        $this->font = $font;

        if($bg && !is_dir($bg)){ //bg file provided?
            $this->bgimg=$bg;
        }else{ //assume dir provided or defaults to local.
            $this->bgimg=rtrim($bg,'/').'/'.$this->bgimages[array_rand($this->bgimages, 1)];
        }
    }

    function getImage(){

        if(!extension_loaded('gd') || !function_exists('gd_info')) //GD ext required.
            return;

        $_SESSION['captcha'] =''; //Clear

        list($w,$h) = getimagesize($this->bgimg);
        $x = round(($w/2)-((strlen($this->hash)*imagefontwidth($this->font))/2), 1);
        $y = round(($h/2)-(imagefontheight($this->font)/2));

        $img= imagecreatefrompng($this->bgimg);
        imagestring($img,$this->font, $x, $y,$this->hash,imagecolorallocate($img,0, 0, 0));

        Header ("(captcha-content-type:) image/png");
        imagepng($img);
        imagedestroy($img);
        $_SESSION['captcha'] = md5($this->hash);
    }
}

?>

Thank you in advance

Sorry I enabled php error reporting on the file include/user/open.inc.php and that returned the following errors

 

Notice: Undefined index: name in /home/sites/it-doneright.co.uk/public_html/support-tickets/include/user/open.inc.php on line 32

Notice: Undefined index: email in /home/sites/it-doneright.co.uk/public_html/support-tickets/include/user/open.inc.php on line 44

Notice: Undefined index: captcha in /home/sites/it-doneright.co.uk/public_html/support-tickets/include/user/open.inc.php on line 142

 

Could they be the reason the captcha is not working?

 

Thank you in advance
