going back to search results

[gerkintrigg]

Hiya.

 

I'm trying to work out how to go back to the search results page from an individual product page. I've tried to use the following code:

 

if (isset($HTTP_REFERER)) {
echo "<a href='$HTTP_REFERER' class='text'>Back to search results</a>";
} else {
echo "<a href='javascript:history.back()' class='text'>Back to search results</a>";
}

 

but the problem is that it just sends the user back to the last page, so isn't reliable enough.

 

I have a product page which contains one or more images, each image requires the page to re-load, so I want to re-direct the user to the search page from any of these iterations.

 

Could someone suggest how to do this? Is there a way of writing search variables into a session identifier that I can easily reference?

 

I know of several ways to do it using if statements and writing lots more sessions but I'm sure there's a cleaner way...
