Get Current Post Type in the WordPress Admin Area

In WordPress, you can create posts, pages, or any custom post type. Within your theme template, you can get the current post type using the core WP function, get_post_type(). But that doesn’t work in the Admin Area. For example, my Disable Gutenberg plugin provides conditional functionality to the “Add New” and “Edit” screens based on […]

Rename uploaded files in WordPress

Here is a function used in my free WordPress plugin User Submitted Posts that enables you to rename WordPress media uploads. So for example, if the user uploads a JPG image named “sweet-ride.jpg”, the following function will append a random string to rename the file “sweet-ride-random.jpg”, where “random” is a random alphanumeric string containing 20 […]

WordPress: Display Site Creation Date

I’m surprised that WordPress doesn’t provide a function for getting the site creation date. Knowing when the site was set up can be useful for all sorts of things. Copyright dates. Bragging rights. Whatever. If you want to display the date your site was first installed, here is one way to do it.

WordPress Disable Self Pings

Depending on your WordPress configuration, plugins, and so forth, your site may be suffering from “self-pings”. Self-pings are pingbacks from your own domain, which are not necessary and look kind of silly displayed alongside other, actual pingbacks. If your site is haunted by self-pings, here is a quick code snippet to stop them.

WordPress template_redirect Example

Quick code snippet showing basic use of the WordPress template_redirect action hook. This is provided as a quick copy/paste reference for WordPress developers. This hook is useful for customizing any functionality requiring full query information.

WordPress Remove Screen Options

Normally the “Screen Options” tab is an awesome little WordPress feature. Located on various screens in the WP Admin Area, the Screen Options tab toggles open any available settings. Like which meta boxes to display, layout columns, editor auto-height, and other options depending on which screen you are viewing. But there may be cases where […]

Fix Chrome Border Radius

I’ve posted before about fixing weird default browser styles. It happens all too often. Well-intentioned browser developers taking liberties on the page with things like CSS styles. This post shares a quick code snippet that fixes the Chrome browser’s new “rounded corners” style that now is applied to form elements like buttons and inputs.

Protect against SQL Injection

Here is a nice copy/paste .htaccess snippet to help block SQL-injection attacks. It can be added as-is to your .htaccess file to help protect against SQL injection and other types of malicious activity. This code is a not a replacement for proper data sanitization, but it does help to add another layer of security to […]

Redirect Attacker to Special Message

If you are using Apache server, you can stop an attack by getting the IP address of the attacker and then using it to block or redirect all of their requests. Normally I just block the requests using either Deny or Require directives (depending on Apache version), but sometimes it’s fun to redirect the attacker […]

WordPress Get Edited Post ID

Working on my plugin Disable Gutenberg, I needed a way to get the ID of an edited post. Not on the front-end, but on the “Edit Post” screen in the WP Admin Area. Unfortunately WordPress does not provide a built-in core function for handling this, so it’s necessary to roll our own solution.

JavaScript & jQuery: Add Style to Fragment Identifier

It’s easy to style a <div></div> by targeting its ID. But what if you only want to add style when a specific fragment identifier is targeted via the URL? So for example, your page at /about/ has a table with all the data. When visitors arrive directly at /about/, no extra styles are added. But […]

Disable Chrome XSS Auditor

Working on WordPress development and testing HTML forms in Chrome browser, I ran into the following error: This page isn’t working Chrome detected unusual code on this page and blocked it to protect your personal information (for example, passwords, phone numbers, and credit cards).
