Excluding posts (or custom post types) from search results when they meet certain criteria is easy in theory. Just use the pre_get_posts action to modify the WP_Query arguments used to get the results. However there are a couple of small pitfalls to watch out for. Below are brief explanations and snippets for excluding posts based …
I often run one off reports for clients directly from the MySQL database behind their (normally WordPress) websites. Most are straightforward, perhaps requiring data from the wp_posts and wp_postmeta tables. However it get's a lot more complicated if term data is needed too. This is because determining which terms belong to an object, what taxonomy …
Let's get a list of all duplicate postcodes (could be any string of course) out of a specific field in the database. This could be handled in PHP but, with a decently spec'd server especially, it's quicker to handle it in the database. The basic query looks like this: (this example is from WordPress but …
Regularly when we launch a new site we also put up a static scrape of the old site so that users can access content that has been removed from the new site. Commonly this is old news content that the client want’s to keep available for a transition period, but doesn’t want cluttering up the …

One gap in the abilities of WP CLI at the moment is the ability to modify an already existing wp-config.php file. v1.2 introduced the –force flag to overwrite an existing one, but that is the sledgehammer option – so I started working on it myself. I have put a very initial version on GitHub and …
VPNs and proxies are great – but almost always limited to funnelling all traffic through them. But what if you want to access only a single site/domain without affecting the rest of your browsing? Perhaps to access a staging site not publically available. While what I discuss below could be used as a privacy measure, …
Updated 02 – 05 – 18: plugins object is now returned as an array. On a whim this May bank holiday, tucked up on the sofa watching movies, I decided to create a plugin to display my favourited plugins on WordPress.org. After a bit of digging I found you can use the plugins_api() function and …
Just to be clear – there are no affiliate links, sponsored content or anything similar in this post. Recently I started taking the JavaScript for WordPress course and would highly recommend it. Not long after I received an email from them promoting their affiliate system – help advertise the course and you get a kick-back. …
