README

This bundle adds into each form a hidden field with an empty value. If the field comes back with a non-empty value, then we assume that the form was filled in by a bot and the form is rejected.

Installation

Applications that use Symfony Flex

Open a command console, enter your project directory and execute:

$ composer require meteo-concept/hiddenfieldantispam-bundle

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Install the bundle with one of the commands above. You now have to enable it and configure it without the recipe.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    MeteoConcept\HiddenFieldAntispamBundle\MeteoConceptHiddenFieldAntispamBundle::class => ['all' => true],
];

Configuration

Configure the bundle, for instance in config/packages/meteo_concept_hidden_field_antispam.yml:

meteo_concept_hidden_field_antispam:
    enabled: true # this is the default
    field_name: "meteo_concept_sentinel" # this is the default

twig:
    form_themes:
        - '@MeteoConceptHiddenFieldAntispam/hidden_field_antispam_form.html.twig' # to hide the antispam field

Usage

You have nothing else to do, the field is automatically added to all root (i.e. non-embedded forms).

Todo

• Randomize the field name, just in case bots would become smart
• More advanced, randomize the field type while leaving it invisible
