"Star rating" field. Add-on to Advanced Custom Fields plugin.

== Description ==

Add the possibility to use rating field in ACF.

Plug-in provide three calculation method for voting:

1. calculate by cookies (any visitor);
2. by IP (any visitor);
3. by user id (registered users only).

If "calculated by cookies" is selected, the only users which use browser with 
cookies enabled will be able to vote

In field settings you can also:

1. open|close vote;
2. tune the number of stars (1 to 20);
3. specify the method of re-voting - possible(period)|never

Use the_field($field_key, $post_id) or get_field($field_key, $post_id) function
in page template for field output (see ACF documentation).

In admin panel the rating is inactive.

== Frequently Asked Questions ==

= How to display field on the page? =

Add the_field($field_key, $post_id) or get_field($field_key, $post_id) into page
template where it is necessary for you (use $field_name only, if you are sure that field value exists):

`<?php
    // add fields in the Loop
    if ( have_posts() ) {
        while ( have_posts() ) {
            the_post();
            if ( function_exists( 'the_field' ) ) {
                the_field( 'quality', $post->ID );
            }
            the_content(); 
        } // end while
    } // end if
?>`
`<?php
    // display rating field for post_id=123
    if ( function_exists( 'the_field' ) ) {
        the_field( 'interest', '123' );
        the_field( 'field_62ad11se531h', '123' );
    }
?>`
`<?php
    // display rating field of user_id = 1
    // to pass $post_id value use 'user_' + user ID format
    if ( function_exists( 'get_field' ) ) {
        $field = get_field( 'field_53ac25b2e521', 'user_1' );
        echo $field;
    }
?>`

= How to display vote results and number of votes? =

Use get_field() function of ACF plugin (with the third option = FALSE), to display 
vote result on the page:
`<?php
    // display voting results of post_id = 123
    if ( function_exists( 'get_field' ) ) {
        $value = get_field( 'interest', '123', FALSE );
        $avrg  = ( ! empty($value['avrg']) ? $value['avrg'] : 0 ) ;
        $votes = ( ! empty($value['votes']) ? $value['votes'] : 0 ) ;
        echo "rating: $avrg; votes: $votes";
    }
?>`
