I'm using this function plugins_url().

But it always echoes main site url even in subsite.

So i'm getting ajax errors like Domains, protocols and ports must match.

Lets say my main domain name is blahblah.com and my subdomain is mysubdomain.blahblah.com

Is there any function available that returns mysubdomain.blahblah.com/wp-content/plugins instead of blahblah.com/wp-content/plugins?



As of now i'm using like this.

home_url( '/' ).'wp-content/plugins/'.str_replace(basename(__FILE__),"",plugin_basename(__FILE__))

Here wp-content/plugins/ text hard coded.

So any other alternative method there?

The plugins_url() function is designed to work in WordPress Multisite. Here is an example of its proper usage:

echo "<img src="' .plugins_url( 'images/wordpress.png' , __FILE__ ). '" > ';

If you are using this function in a file that is nested inside a subdirectory, you should use PHP's dirname() function:

echo "<img src="' .plugins_url( 'images/wordpress.png' , dirname(__FILE__) ). '" > ';
