Here's how you add a url in the coupon store

I am surprised that author has left the plugin broken so far with no fix in sight.

Here’s how to make the url addition possible.

Open plugin folder/admin_functions/social_settings.php and find this code

,/*
"coupon_store_url" => array (
   "name"		=> "coupon_store_url",
    "default" 	=> "",
    "label" 	=> "Coupon Store URL",
    "type" 		=> "text",
    "desc"      => "The URL where coupon can be redeemed."
)*/

Remove the /* and */ around it. The author had the code in the plugin but for some reason it has been kept commented. The final code should look like

,
"coupon_store_url" => array (
	"name"		=> "coupon_store_url",
	"default" 	=> "",
	"label" 	=> "Coupon Store URL",
	"type" 		=> "text",
"desc"      => "The URL where coupon can be redeemed."
)

Now open the index.php in the main plugin folder and find this code

get_post_meta($store_id,'coupon_store_url',true),

and change it to

$post_meta['coupon_store_url'][0],

This should do it. Now you can add the url from the edit post page and they will feature properly in the frontend.
