SPAM protection - captcha/magento session data problem

peerus Total Posts: 45 Joined: 2008-09-14 Ignore user	I’m trying to integrate http://www.phpcaptcha.org/ http://www.magentocommerce.com/boards/viewthread/18885/ http://www.magentocommerce.com/boards/viewthread/25296/ I started with contacts form 1. .../design/...form.phtml .. <label for="captcha_code">Captcha code<span class="required">*</span></label><br /> <input name="captcha_code" id="captcha_code" title="Code" value="" class="required-entry input-text" type="text" /> <img id="captcha_image" src="/lib/phpcaptcha/securimage_show.php"/> <?php if (!isset($_SESSION['andrey_counter'])) $_SESSION['andrey_counter']=0; $_SESSION['andrey_counter']++; $_SESSION['andrey_test_value'] = "this is test"; $fp = fopen('/home/webmaster/www/dev/lib/phpcaptcha/01.txt', 'w'); fwrite($fp, 'sid: ' . session_id() . "\n"); fwrite($fp, 'sname: ' . session_name() . "\n"); fwrite($fp, 'refreshed: ' . $_SESSION['andrey_counter'] . "\n"); fwrite($fp, 'test: ' . $_SESSION['andrey_test_value'] . "\n"); fclose($fp); ?> .. Data in file is OK. 1.txt `sid: ebbe5f40ed32d30f83a19f9480a2ec0c sname: frontend refreshed: 19 test: this is test` 2. /lib/phpcaptcha/securimage_show.php By default session for this script differs from magento session. So i’m trying to share magento’s session. <?php include 'securimage.php'; ini_set('display_errors',1); error_reporting(E_ALL); session_start(); //print_r(getallheaders()); if (!isset($_SESSION['andrey_counter'])) $_SESSION['andrey_counter']="not set"; if (!isset($_SESSION['andrey_test_value'])) $_SESSION['andrey_test_value']="not set"; $fp = fopen('/home/webmaster/www/dev/lib/phpcaptcha/02.txt', 'w'); fwrite($fp, 'sid: ' . session_id() . "\n"); fwrite($fp, 'sname: ' . session_name() . "\n"); fwrite($fp, 'refreshed: ' . $_SESSION['andrey_counter'] . "\n"); fwrite($fp, 'test: ' . $_SESSION['andrey_test_value'] . "\n"); fclose($fp); $img = new securimage(); $img->show(); ?> Data in file is not OK $_SESSION[’andrey_counter’] and $_SESSION[’andrey_test_value’] is empty! I don’t know howto fix this. Take a look at sname. PHPSESSID not equals frontend (see 1.txt) 2.txt `sid: ebbe5f40ed32d30f83a19f9480a2ec0c sname: PHPSESSID refreshed: not set test: not set` 3. app/code/../contacts/.. /IndexController.php ... $captha_code = $postObject->getCaptcha_code(); ... if (!isset($_SESSION['andrey_counter'])) $_SESSION['andrey_counter']="not set"; if (!isset($_SESSION['andrey_test_value'])) $_SESSION['andrey_test_value']="not set"; $fp = fopen('/home/webmaster/www/dev/lib/phpcaptcha/03.txt', 'w'); fwrite($fp, 'sid: ' . session_id() . "\n"); fwrite($fp, 'sname: ' . session_name() . "\n"); fwrite($fp, 'refreshed: ' . $_SESSION['andrey_counter'] . "\n"); fwrite($fp, 'test: ' . $_SESSION['andrey_test_value'] . "\n"); fclose($fp); ... Data in file is OK. 3.txt `sid: ebbe5f40ed32d30f83a19f9480a2ec0c sname: frontend refreshed: 18 test: this is test` So my problem is the session! How can i share data between magento and simple php script?

Modify securimage.php `.. public $strcode = NULL; function generateCode($len) { $code = ''; if ($this->strcode == NULL) { for($i = 1, $cslen = strlen($this->charset); $i <= $len; ++$i) { $code .= strtoupper( $this->charset{rand(0, $cslen - 1)} ); } } else { $code = $this->strcode; } return $code; } ..` 3. modify securimage_show.php `<?php include 'securimage.php'; $img = new securimage(); if (isset($_GET['seccode'])) { $img->strcode = substr($_GET['seccode'], 6, 4); } $img->show(); ?>` 4. For example insert code into app/design/frontend/default/default/template/contacts/form.phtml Here we generate code and send it to securimage_show script. not good idea but at least works. You should encode code here and decode it in securimage_show.php .. <div class="clear"></div> <div class="input-box"> <label for="captcha_code">Enter code<span class="required"></span></label><br /> <input name="captcha_code" id="captcha_code" title="Code" value="" class="required-entry input-text" type="text" /> <img id="captcha_image" src="/lib/phpcaptcha/securimage_show.php?seccode=<?php require_once 'lib/phpcaptcha/custom_code.php'; $as_code = generateCode(4); $_SESSION['as_contacts_code'] = $as_code; echo 'BLABLA' . $as_code . BLA'; ?>"/> </div> .. 5. Install Exanto_Contacts.xml http://www.magentocommerce.com/extension/534/exanto-contacts Modify app/code/local/Exanto/Contacts/controllers/IndexController.php ... public function postAction() { $post = $this->getRequest()->getPost(); if ( $post ) { $translate = Mage::getSingleton('core/translate'); / @var $translate Mage_Core_Model_Translate */ $translate->setTranslateInline(false); try { $postObject = new Varien_Object(); $postObject->setData($post); //CAPTCHA $captha_code = $postObject->getCaptcha_code(); $as_code = ''; if (isset($_SESSION['as_contacts_code'])) { $as_code = $_SESSION['as_contacts_code']; } if ((strtolower($captha_code) != strtolower($as_code))) { Mage::getSingleton('customer/session')->addError(Mage::helper('contacts')->__('Введен неверный код.')); } else { //CAPTCHA .... If someone needs all sources for contacts, register and lazymonk blog comment - PM me. I’ll publish it here Signature Magento fan concerned by Multi Images import http://www.magentocommerce.com/boards/viewthread/6220/ Customer group pricing http://www.magentocommerce.com/boards/viewthread/108/
