Help?

and works with PS 1.5.6.1

changing your product-list.tpl from:

{section name=”i” start=0 loop=5 step=1}
{if $smarty.section.i.index lt $average_total}

{else}

{/if}
{/section}

To:

{if $smarty.section.i.index lt $average_total == ‘0’}

{else}

{section name=”i” start=0 loop=5 step=1}
{if $smarty.section.i.index lt $average_total}

{else}

{/if}
{/section}

{/if}

Just a small addition to make no stars show up if the average is 0 or there has been no comments left yet.
Keep Up The Good Work!

Is it possible to add, to the right of the stars, the average rating along with the number of reviews in parenthesis, much like the Best Buy website ratings? Something like:

gold star;gold star;gold star;grey star;grey star 3.6 out of 5 (44 Reviews)

Thanks Nemo for a great tutorial!

I copied the code that Juda provided and added it just above the last } in my productcomments.php file. Am I doing something wrong?

Thanks!

Tiny detail, which caused some problem to someone on the forum:

Quote:
Step 3 – Creating the hooking function
So, we have our hook. Let’s test it out. At the end of productcomments.php create a new function

They took your suggestion a little too literally, and added it fully at the end of the file, OUTSIDE the class…

So, we have to make sure it’s JUST ABOVE the very last “}”, to keep the function INSIDE the class, to make it part of it:

add our code here
}
— END OF FILE–

Hope this helps,
pascal

I copied wrong the product-list.tpl

Now works fine

thanks
