Usage
First obtain the appropriate keys for the type of hCAPTCHA you wish to integrate at https://www.hcaptcha.com/
Then follow the integration guide on the developer site to add the hCAPTCHA functionality into your frontend.
This library comes in when you need to verify the user's response. On the PHP
side you need the response from the hCAPTCHA service and secret key from your
credentials. Instantiate the HCaptcha
class with your secret key, specify any
additional validation rules, and then call verify()
with the hCAPTCHA
response and user's IP address. For example:
The following methods are available:
setExpectedHostname($hostname)
: ensures the hostname matches. You must do this if you have disabled "Domain/Package Name Validation" for your credentials.setExpectedApkPackageName($apkPackageName)
: if you're verifying a response from an Android app. Again, you must do this if you have disabled "Domain/Package Name Validation" for your credentials.setExpectedAction($action)
: ensures the action matches for the v3 API.setScoreThreshold($threshold)
: set a score threshold for responses from the v3 APIsetChallengeTimeout($timeoutSeconds)
: set a timeout between the user passing the hCAPTCHA and your server processing it.
Each of the set
*()
methods return the HCaptcha
instance so you can chain
them together. For example:
You can find the constants for the libraries error codes in the HCaptcha
class constants, e.g. HCaptcha::E_HOSTNAME_MISMATCH
