The poll plugin sets up a matrix field that contain the answers, a section that contains the polls and a field that makes it easy to add polls to existing content.
These fields and sections have handles that may be configured. In some cases you might want to specify non-default handles for your site (for example if they conflict with existing handles).
Caution: If you modify handles after the poll plugin is already in use and set-up, you should rerun the setup and manually remove old handles and content if you choose to.
You can do so by placing a file 'poll.php' in your craft config directory:
<?php
// example config file to override section handles etc
// these settings would override the settings set from the CP
return [
// configure handles for installation
// the section containing polls
// default: pollSection
'sectionHandle' => '',
// the field that is generated to select a poll
// default: selectedPoll
'selectPollFieldHandle' => '',
// the matrix that contains 'answers'
// default: pollAnswerMatrix
'answerMatrixFieldHandle' => '',
// within the answerMatrixFieldHandle, a block is created that will contain the answers.
// this is the handle for that block.
// default: answer
'matrixBlockAnswerHandle' => ''
];
