You can connect CAPTCHA as follows:
|
Connecting CAPTCHA in module settings |
CAPTCHA are connected directly in module settings. For example, the Use CAPTCHA option in the Main/kernel module allows using CAPTCHA when registering new users:
|
Connecting CAPTCHA in custom scripts, modules or components |
First, create CAPTCHA to be used :
01 <?include_once($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/classes/general/captcha.php");
02 $cpt = new CCaptcha();
03 $captchaPass = COption::GetOptionString("main", "captcha_password", "");
04 if(strlen($captchaPass) <= 0)
05 {
06 $captchaPass = randString(10);
07 COption::SetOptionString("main", "captcha_password", $captchaPass);
08 }
09 $cpt->SetCodeCrypt($captchaPass);
10 ?>
Next, print three elements inside the form: hidden field with generated code, field to enter captcha by the user and the image itself.
<input name="captcha_code" value="<?=htmlspecialchars($cpt->GetCodeCrypt());?>" type="hidden">
<input id="captcha_word" name="captcha_word" type="text">
<img src="/bitrix/tools/captcha.php?captcha_code=<?=htmlspecialchars($cpt->GetCodeCrypt());?>">
Add a check in the script used to submit the form:
01 <?
02 if(!$APPLICATION->CaptchaCheckCode($_POST["captcha_word"], $_POST["captcha_code"]))
03 {
04 // Incorrect value
05 }
06 else
07 {
08 // Correct value
09 }
10 ?>
