FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package captcha

InfoPeak Captcha for PHP

Server-side verification for InfoPeak Captcha - the privacy-first, EU-hosted captcha. No tracking, no cookies, no image puzzles.

Install

Requires PHP 7.4+ with the curl and json extensions.

Usage

Add the widget to your form (full guide):

Verify the token when the form is submitted:

Need quota information too?

Verification fails closed: network errors and non-200 responses return valid = false.

Retrying a rejected submission

Tokens are single-use. If you reject a submission and leave the visitor on the same page - an AJAX form, a wrong password, a validation error - the token already in the form is spent, and the next attempt fails on the captcha instead of on the real problem. Ask the widget for a fresh one:

reset() clears the hidden field and solves again immediately, and returns the number of widgets it reset. Plain form posts do not need this - the page reload builds a new widget anyway.

Testing

Public test credentials that work on any domain and never count against a quota (never use in production):
