Honeypot Class¶
The Honeypot Class makes it possible to determine when a Bot makes a request to a CodeIgniter4 application,
if it’s enabled in Application\Config\Filters.php
file. This is done by attaching form fields to any form,
and this form field is hidden from a human but accessible to a Bot. When data is entered into the field, it’s
assumed the request is coming from a Bot, and you can throw a HoneypotException
.
Enabling Honeypot¶
To enable a Honeypot, changes have to be made to the app/Config/Filters.php
. Just uncomment honeypot
from the $globals
array, like…:
public $globals = [
'before' => [
'honeypot'
// 'csrf',
],
'after' => [
'toolbar',
'honeypot'
]
];
A sample Honeypot filter is bundled, as system/Filters/Honeypot.php
.
If it is not suitable, make your own at app/Filters/Honeypot.php
,
and modify the $aliases
in the configuration appropriately.
Customizing Honeypot¶
Honeypot can be customized. The fields below can be set either in
app/Config/Honeypot.php
or in .env
.
