Message:

On my website's homepage, I use a chart that counts all Woocommerce reviews. These reviews are shown as a percentage for each rating (1 star, 2 star etc ...). I need to change functionality to the total number of ratings for each rating section instead of the percentage and display stars instead of labels.

Any advice?

Now:

Goal:

Code of the graph:

function display_all_product_review_histogram($minimum_rating, $maximum_rating){

    

    $all_product_review_average_rating = get_all_product_review_average_rating($minimum_rating, $maximum_rating);

    $total_ratings = $all_product_review_average_rating[0]["total_ratings"];



    $get_all_product_review_counts_by_ratings = get_all_product_review_counts_by_ratings($minimum_rating, $maximum_rating);



    if($get_all_product_review_counts_by_ratings){

        $output = '';

        $sum = 0;

        $total = 0;

        $raw_percentages_array = array();

        $percentages_array = array();



        //When working with rounded percentages, we must make sure the total percentages add up to 100%.

        //Creating array of rating values and its percentage

        foreach ($get_all_product_review_counts_by_ratings as $key => $rating) {

            $percentage = round($rating["amount"] / $total_ratings, 2) * 100;

            $raw_percentages_array[] = array("value" => $rating["value"], "percent_of_total" => $percentage);

        }

        //Counting the total of our percents

        foreach($raw_percentages_array as $key => $percent) {

            $total += $percent[ "percent_of_total" ];

        }

        //Creating an array that will have the actual percentages after the rounding has been applied to it.

        //This will help to see if we have 100% or we are not aligned

        foreach($raw_percentages_array as $key => $percent){

            $percentages_array[$percent["value"]] = round(($percent["percent_of_total"]/$total) * 100, 0);

        }

        $sum = array_sum($percentages_array); //Again counting the total of our new percents to see if it adds up to 100%



        if($sum != 100){ //If we do not have 100%, then we will alter the highest percentage value so that we get a total of 100%

            $highest_percentage_key = array_keys($percentages_array, max($percentages_array)); //Getting key of the highest percentage value

            $percentages_array[$highest_percentage_key[0]] = 100 - ($sum - max($percentages_array)); //Alterning the percentage

        }



        //Now we are ready to create the output that will give us 100% in total

        $output .= "<div class='product-review-histogram'>";

        foreach ($percentages_array as $key => $percentage) {

            $output .= "<div class='histogram-row star-rating-". $key ."'>";

            $output .= "<div class='histogram-col-1'>". $key ." star</div>";

            $output .= "<div class='histogram-col-2'><div class='histogram-meter-bar'><div class='histogram-bar-temperature' style='width: ". $percentage ."%'></div></div></div>";

            $output .= "<div class='histogram-col-3'>". $percentage ."%</div>";

            $output .= "</div>";

        }

        $output .= "</div>";



        return $output;

    }else{

        return;

    }

}

My Answer:
$total_ratings = get_all_product_review_count($minimum_rating, $maximum_rating); // Get total number of ratings for each rating section
$total_reviews = array_sum($total_ratings); // Get total number of reviews
$rating_labels = array(1, 2, 3, 4, 5); // Define rating labels
$rating_stars = array('★', '★★', '★★★', '★★★★', '★★★★★'); // Define rating stars

// Display the chart
echo '';
}

// Call the function with minimum and maximum rating parameters
display_all_product_review_histogram(1, 5);
