Gravity Forms GFAPI::submit_form bug

There is a bug with the Gravity Forms GFAPI::submit_form method when the $_POST variable contains any existing values that match what you pass to GFAPI::submit_form.

Because GFAPI::submit_form internally uses array_merge_recursive, any existing values in the $_POST variable will be added to any values that exist in the second parameter that you pass to GFAPI::submit_form.

This bug appears in the latest version of Gravity Forms 2.4.20.5 and in the latest 2.5 beta

Add a /blog to your WordPress blog posts only and remove it from the other post types

This is useful if you want to know when a user is viewing a blog post in Google Analytics vs a page. Or if you want to just have an easy way to distinguish your blog content from your other content using the URL.

There may be an easier way to do this but all of my Googling didn't turn up any answers that let you modify the post URLs only.

1. Add the code from remove-blog-front-from-custom-post-types.php to your theme's functions.php or to a custom plugin or some file where it will get loaded. This code prevents the new blog base from being applied to the URLs of Custom POst types and taxonomy archives.
2. Log into your WordPress admin
3. Go to Settings -> Permalinks
4. Select the Custom Structure field and add /blog to the Permalink structure (add this before the /%postname% part of the URL
