WP-Polls

To show specific poll, use <?php get_poll(2); ?> where 2 is your poll id.
To show random poll, use <?php get_poll(-2); ?>
To embed a specific poll in your post, use [poll id="2"] where 2 is your poll id.
To embed a random poll in your post, use [poll id="-2"]
To embed a specific poll's result in your post, use [poll id="2" type="result"] where 2 is your poll id.

General Usage (With Widget)

Go to WP-Admin -> Appearance -> Widgets.
You can add the Polls Widget by clicking on the 'Add' link besides it.
After adding, you can configure the Polls Widget by clicking on the 'Edit' link besides it.
Click 'Save Changes'.
Scroll down for instructions on how to create a Polls Archive.

Go to WP-Admin -> Pages -> Add New.
Type any title you like in the post's title area.
If you ARE using nice permalinks, after typing the title, WordPress will generate the permalink to the page. You will see an 'Edit' link just beside the permalink.
Click 'Edit' and type in pollsarchive in the text field and click 'Save'.
Type [page_polls] in the post's content area.
Click 'Publish'.

If you ARE NOT using nice permalinks, you need to go to WP-Admin -> Polls -> Poll Options and under Poll Archive -> Polls Archive URL, you need to fill in the URL to the Polls Archive Page you created above.

It is because of rounding issues. To make it always round up to 100%, the last poll's answer will get the remainding percentage added to it. To enable this feature, add this to your theme's functions.php: add_filter( 'wp_polls_round_percentage', '__return_true' );

WP-Polls will load polls-css.css from your theme's directory if it exists.
If it doesn't exists, it will just load the default polls-css.css that comes with WP-Polls.
This will allow you to upgrade WP-Polls without worrying about overwriting your polls styles that you have created.

To solve this issue, Open poll-css.css
Find: /* background-color: #ffffff; */
Replace: background-color: #ffffff; (where #ffffff should be your background color for the poll.)

Translating the template
The plugin templates can be translated via template variables.
There are these filters for the custom template variables

wp_polls_template_votebody_variables
wp_polls_template_votefooter
wp_polls_template_resultheader_variables
wp_polls_template_resultbody_variables
wp_polls_template_resultfooter_variables

Add filter to your theme and register custom variable where you will add your translation.
Good practice is to name them for example with prefix STR_ in the example STR_TOTAL_VOTERS.

/**
* Localize wp_polls_template_resultfooter_variables.
*
* @param array $variables An array of template variables.
* @return array $variables Modified template variables.
*/
function wp_polls_template_resultfooter_variables( $variables ) {

// Add strings.
$variables['%STR_TOTAL_VOTERS%'] = __( 'Total voters', 'theme-textdomain' );

return $variables;
}

// Trigger the filter
add_filter( 'wp_polls_template_resultfooter_variables', 'wp_polls_template_resultfooter_variables' , 10, 1 );

In the admin side just call the custom variable like so and the variable has been translated in the front-end.
%STR_TOTAL_VOTERS%'
