The problem is that the "dev" says to create this file and pop it into your photopost directory. He never says what it's for or how to access it via the widget. He basically misses a step... No biggy.
So this is what you do...
Create the file as specified. I called mine test.php.
Code:
<?php
include "/home/myname/public_html/gallery/inc_features.php";
echo "$photopostfeature" ;
?>
I popped the test.php file into my photopost directory.
next, you have to reference the file you've created in the widget...
Code:
ob_start();
echo '<div>';
echo '<center>';
require_once '/home/myname/public_html/gallery/test.php;
echo '</center>';
echo '</div>';
$output=ob_get_contents();
ob_end_clean();
and that's it!
Hope this helps!
