Add featured image to admin table in WordPress for custom post type
On a project I’m doing, I created a custom post type for a catalogue and want the featured image to display on the admin table.
My custom post type is called “product” and I want to limit the feature to only the “product” custom post type. Here’s how I did it.

$ is not a function in WordPress
When building your own theme in WordPress, using Jquery with $ might cause issues. To fix this wrap your code in this:
Remove container and UL on WordPress nav menu
Sometimes you might want to programatically include other things in your menu in WordPress and to do that you will want to control the UL tags so you can insert other LI items within it.
The code below will allow you to spit out ONLY the LI tags from a WordPress Nav Menu, you will have to wrap it in UL yourself so you can add extra LI.
Remove ‘category’, ‘archive’, etc from get_the_archive_title()
Remove the prepended ‘Category:’ or ‘Archive:’ when trying to echo the name of the archive in WordPress.
Loop through Taxonomies and list posts underneath
In my WordPress site, I had a need to list all taxonomies and underneath them, their related custom post types.
To do this, I used this code below. Obviously replace “custom_taxomy” with your taxonomy name and “custom_post_type” with your post type name.
Add inline JS to WordPress footer
Adding JS to WordPress can be done in two ways. The first way is to enqueue the JS file.
The second way can be done by adding inline JS via a hook in functions.php – this is most likely used to initialize a script that is enqueued or add Google Tracking codes, Facebook pixels etc.

Remove gravity forms unlicensed message
Gravity forms is a great forms plugin for WordPress. I purchased a licence and it lapsed, but I still use it on my website. The problem is, because the licence is lapsed, I am seeing an ugly, annoying message saying that my copy is unlicensed. Just to clarify, I did buy a licence, and I am allowed to use the copy, I just don’t want to renew it for a new version.
To remove the nag, it’s a bit tricky, Gravity Forms have gone above and beyond to make it difficult for people to do to protect their bottom line and just annoy someone to eventually re-licence.
However, with that being said, just add this to your functions.php file.
