converting numbers into graphics

Hi,

I'm using PHP/MySql. I have a rating system on my review page where each category is rated out of 10. Film, video, audio, extras and overall.

Instead of echoing the rating, I now want to convert it into a graphic. For example '1' represents '1' star etc.

I thought of evaluating the record using if/else to display graphics, but for 5 categories each with a possible 10 stars, it could be big!!

Is there an elegant way of doing this? Any pointers are much appreciated!

Cheers!

Maybe like this: Question

Code:

echo('<img src="images/ratings/'.$rating.'.gif" />');

Hmmm, not sure. I have the existing code:

Code:

<?php echo $row_R['ratingfilm']; ?>

which echoes the rating from the dbase. For example: 8

I want to turn it into a graphic. So '8' stars should be in it's place. If it was 1, then '1' star.

Wouldn't I need to evaluate the rating first, and then fetch a graphic to represent it? I would think there are 10 graphic images going from 1 star to 10 stars.

Code:

if ($row_R['ratingfilm'] == 1)
<img src="assets/images/1star.gif">
else do this instead

This is what I think, but then I'm not sure how to code it. I'm sure there must be a good way to do it!

Here's an easy way. Create your graphics and name them 1star.gif, 2star.gif, ..., 10star.gif. Next, try this:

Code:

echo "<img src=" . $row_R['ratingfilm'] . $"star.gif" />"

That will add the rating number to the beginning of your file name, resulting in your reference to the proper graphic. Make sense?

Code:

for($i = 0; $i < $row_R['ratingfilm']; ++$i)
print '<img src="assets/images/1star.gif">';

that should print the image tag the same number of times as the value of the rating...so you will get the star image five times for a rating of five.

cheers all!

It's painfully obvious that I wonder why I didn't see it! D'oh! Very Happy

I'm off to sleep now, I'll deal with it in the morning.
