I have a WordPress plugin that shows a ratting snippet for Google. 1.0 – 5.0 and I would like to add a image for the value selected, right after the rating, but it doesn’t.
So far I have got it to load the image but it doesn’t show up where I want it to, and that is where I am stuck.
Here is was I tried to add:
if ($rating == "5.0"){ print("<IMG SRC ="stars/5-0.png>");}
here is the plugin code:
<?php
$prefix = 'pk_rs_';

'fields' => array(
array(
'name' => 'Rating',
'desc' => 'Product rating, from 1 to 5.',
'id' => 'rating',
'type' => 'select',
'options' => array('-', '1.0', '1.5', '2.0', '2.5', '3.0', '3.5', '4.0', '4.5', '5.0')

I’d do something like:
And then modify the line that says:
