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 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 […]

WordPress: Get All User Roles

WordPress makes it easy to get the current user’s role(s) by using wp_get_current_user(). But what if you want to get all roles from all users. Like a list of every role that is used on your site. Well good news, WordPress provides a global object named $wp_roles that provides the information. So if you’re looking […]

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.

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 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 […]

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 […]

Contact Form X

There are a million contact form plugins, but this one is MINE. One of the primary communication channels for my online empire is the Perishable Press Contact Page. I get a TON of email from that location, all coming from different projects, plugins, books, tutorials, etc. So the contact form that I display must be […]

New WordPress plugin: Banhammer!

Quick post to announce my latest WordPress security plugins, Banhammer (free version) and Banhammer Pro. These plugins give you full control over site access, enabling you to warn or ban any user or bot with a click. So you can monitor traffic via slick Ajax UI, and drop the Banhammer on any suspicious or threatening […]

503 Service Unavailable Headers via PHP

Sending a few HTTP headers is a simple way to let visitors and search engines know that your site currently is unavailable. This is useful when you are doing maintenance and don’t need access to the front-end of your site. Simply add the rules when your site is down, and then remove them once everything […]
