I wish to use Processwire to extend the CMS functionality that is limited in Open Cart and thought of having a /processwire subdirectory and using the API as described in http://processwire.com/api/include/
However, I have stumbled at the first block by trying to include the Processwire index file. I get an error.
I tried these:
<?php include('/home/opencart/public_html/processwire/index.php');
<?php include('http://absoluteurl/index.php');
<?php include('../../..relativeurl/index.php');
Can someone give more detail on how to access the Processwire API from an external application?
