Brand logo making a link

Question

I am successfully using this code to display a brand logo

php $brand=$_product->getAttributeText('brand');

echo '

'_',$brand).'.jpg" alt="'.$brand.'">'

now what i need help with is making it a link as well

the problem is where as

My brands have capital letters as my attribute does so for example Brand Punch It Performance uses image Punch_It_performance.jpg

however the url for it is

/shop-by-brand/punch-it-performance.html

now forgive my newbieness to php here but i could really use some help modifying the above code snippet to function so when its clicked it goes to the proper page

Answer 1

This should do it:

<?php
$brand = $_product->getAttributeText('brand');
$brandImage = str_replace(' ', '_', $brand) . ".jpg";
$brandLink = strtolower(str_replace(' ', '-', $brand)) . ".html";
$brandBaseUrl = Mage::getBaseUrl() . '/shop-by-brand/';
?>
<a href="<?php echo $brandBaseUrl . $brandLink; ?>" title="<?php echo $brand; ?>">
    <img src="<?php echo $this->getSkinUrl("images/media/" . $brandImage); ?>" alt="<?php echo $brand; ?>" />
</a>

Edit1: fixed typo
