I would suggest you backup your plugin first, test it on a localhost server.
1. Go and edit wpc-catalogue.php
2. Add the following code
//Added this part after the $post_data = get_post($post->ID, ARRAY_A);
// Which basically came from single-wpcproduct.php
$terms1 = get_the_terms($post->id, 'wpccategories');
if($terms1) {
foreach( $terms1 as $term1 ) {
$slug = $term1->slug;
$tname = $term1->name;
$cat_url = get_bloginfo('siteurl').'/?wpccategories=/'.$slug;
};
}
Then look for this part of the code
while($products->have_posts()): $products->the_post();
and insert this code
//this the code for fetching the price
$product_price = get_post_meta(get_the_id(), 'product_price', true);
After this part
$price = get_post_meta(get_the_id(),'product_price',true);
Then look for this line of code, and insert $product_price like this one
$return_string .= '<p class="wpc-title"><a href="'. $permalink .'">'.$title.'?'.$product_price.'</a></p>';
Sorry, for the complicated instructions I was just messing with the plugin files, and eventually made it work.
