Thanks for your help, below is what I used to get it to work if(empty($_POST['txtcaseno']) && empty($_POST['txtparcel']) && empty($_POST['txtlname']) && empty($_POST['txtfname']) && empty($_POST['txtstreet'])){ header('Location: index.php'); exit(); } else { $caseno = $_POST['txtcaseno']; $parcelno= $_POST['txtparcel']; $lname= $_POST['txtlname']; $fname= $_POST['txtfname']; $street= $_POST['txtstreet']; $time = time(); // Gets the Current Server Time setcookie("MasonCoPermits[caseno]", $caseno, $time + 3600); setcookie("MasonCoPermits[parcelno]", $parcelno, $time + 3600); setcookie("MasonCoPermits[lname]", $lname, $time + 3600); setcookie("MasonCoPermits[fname]", $fname, $time + 3600); setcookie("MasonCoPermits[street]", $street, $time + 3600); header('Location: search_results.php'); }

I have a search form page, which sends data to page that sets cookies, then redirects to the search results. What I would like to do is first check to see if 1 of the 5 form fields that was submitted to the setcookie page has something in it. If none are set, then return them to the search page. If at least 1 or more are set, send them to the search results page.

I am trying to use the catpcha provided by: http://www.white-hat-web-design.co.uk/articles/php-captcha.php When I visit form.php, it loads, but the image is unavailable (square with red x), hence i can not see the captcha characters. I have checked and I do have GD and Freetype installed with PHP I have a simple page, located in the root of the site, which contains: --form.php <form action="form.php" method="post"> <img src="CaptchaSecurityImages.php" /> Security Code: <input id="security_code" name="security_code" type="text" /> </form> --CaptchaSecurityImages.php <?php session_start(); class CaptchaSecurityImages { var $font = 'monofont.ttf'; function generateCode($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 $code; } function CaptchaSecurityImages($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['security_code'] = $code; } } $width = isset($_GET['width']) && $_GET['height'] < 600 ? $_GET['width'] : '120'; $height = isset($_GET['height']) && $_GET['height'] < 200 ? $_GET['height'] : '40'; $characters = isset($_GET['characters']) && $_GET['characters'] > 2 ? $_GET['characters'] : '6'; $captcha = new CaptchaSecurityImages($width,$height,$characters); ?>

Is it possible to capture the computer / machine name of people who are visiting your site?
