If you have ever wanted to display your posts (or a post type archive) in a random order, but keep the pagination consistent then here’s your solution.
I put together a .gitignore file that will exclude all WordPress core files from your repo so that only your themes and plugins will be uploaded – this works recursively, so that it will ignore all the copies of WordPress you have in the sub-folders of the repo.
When building a plugin that has its own settings page, it’s often handy to create a link to the settings page straight from the Plugins list – this saves users the time it takes to find where exactly your plugin appears in the admin menu. Here is a simple code snippet that creates the settings link for you – all you need to do is tell it where to go.
In order to minimise the amount of plugins your site uses, here’s a simple function I use to show a post’s featured image in the RSS feed (something WordPress does not do by default).
A quick line of code to ensure that your WordPress content editor will always land on the HTML tab by default. This will ensure that your HTML tags & attributes are never stripped automatically.
I recently had to create an interview test for a developer who has good skill in PHP, but is not so experienced when it comes to front-end coding. On the front-end side of things, the job they were interviewing for required decent HTML & CSS knowledge. With that in mind I created a little test to evaluate their skills – I’m posting it here for anyone else who needs something similar.
