You would use a small data base table and a handful of graphics.  As members vote you update the data base table.  As each page is created, you choose the graphic based on the average of the votes.

The design for counting and reporting the votes is shown in this article.

Here's the PSD file with the star layers.  You can resize it to suit your application needs and save the layers as PNG images

ok thanks for the update.

how ever the images are not being returned correctly. here is the path in .php

// CREATE A LINK TO A FIVE-STAR RATINGS IMAGE
    $x = str_pad($x, 2, '0', STR_PAD_LEFT);
    $stars[$color]
    = './RAY_EE_images/stars'
    . $x
    . '.png'
    ;

Open in new window


i labeled it stars because the layers are labeled that way.

here is the view source:

</form></body>
</html>

Open in new window

Do you have a copy of Photoshop?

If so, you would make all of the layers invisible except for the one you wanted to see.  Then you would save the image as a PNG.  There are 11 layers that matter.

If you do not have Photoshop, I can upload a collection of images for you.  These will be 80 pixels wide by 16 pixels high, as shown in the screen capture in the article.  But going forward if you are going to develop web sites you might want to buy Photoshop or get to be good friends with a designer who has a copy.

XLNT.  Photoshop can take some time to learn, but once you get the concepts of layers and masks, a lot of creative opportunity opens up!
