4 Ways to Make a WordPress Site Private Access Only

LOTR: Doors of Durin

Have you ever wanted to make a WordPress site private? So that only specific users are allowed access? For example, for my found-images site eChunks.com, I decided to require user login in order to access any content. So now for that site, public access is not allowed, and any posts, images, and all other content is available only to logged-in users. This tutorial explains four ways to make a WordPress site private or members only, so that only authenticated/trusted users […] Continue reading »

Code Snippets to Customize WordPress Sitemaps (Complete Guide)

Code Snippets for WP Sitemaps

By now most have heard about the WP Sitemaps feature introduced in WordPress version 5.5. From what I’ve read most existing sites that needed a sitemap already had one via one of the many free sitemap plugins. But for new WordPress sites going forward, having all the sitemap code in the WordPress core now means that new sites have the option of rolling with the default WordPress sitemaps, or use a dedicated plugin to do the job. This post is […] Continue reading »

Building the Perishable Press Bookstore

[ Perishable Press Books (screenshot) ]

After six months of on-again, off-again hard work (and plenty of unexpected challenges), I am excited to launch the new Perishable Press Bookstore. The old bookstore was located on a separate domain, but I wanted it to be better integrated with the main site here at Perishable Press. So now there is the site blog at perishablepress.com and the store at books.perishablepress.com. Continue reading »

Weird Bug with Highlight.js

Working on adding syntax highlighting to my code snippets here at Perishable Press. To do it, I use my free WordPress plugin Prismatic. Basically all the plugin does is load up either the Highlight.js scripts and styles, or it loads up the Prism.js scripts and styles. So I can rule out the plugin itself for this “weird” little bug. The issue is with Highlight.js specifically. Continue reading »

Redesign #25: Performance Over Perfection

[ Previous site design: the X theme ]

Welcome to the 2020 (25th!) redesign for Perishable Press. Like many of the previous designs, the new design is super minimal and organic. The #1 goal this time around was to find an optimal balance between performance and aesthetics. Or put another way.. Continue reading »

How to Modify GET and POST Requests with WordPress

[ POST Requests ]

I’ve written before about protecting against malicious POST requests using Apache/.htaccess. In this tutorial, we’ll look at how to modify GET and POST requests using PHP and some core WordPress functionality (with no .htaccess required). Normally you would want to manipulate URI requests at the server level, but that’s not always possible (like on shared hosting). So in those cases where you want to modify GET, POST, or other types of requests on a WordPress site, check out the following […] Continue reading »

How to Disable WordPress Automatically Generated Images – Complete Guide

[ WordPress Image Sizes ]

As you may know, WordPress creates numerous copies of all images uploaded via the WP Media Library. These additional images are generated in various sizes, depending on your settings and other factors. This may be totally fine in general, but if you are working with lots of images on your site, the extra files can really eat up your disk space. This can be wasteful, specially if your site does not make use of all the extra images. So to […] Continue reading »

Case of the Invisible CSS ::selection

[ Scooby Doo Intro ]

Recently I noticed a weird bug in my free WordPress security plugin, Banhammer. For some reason, I could not select any text on the page. Usually when you click and move the mouse cursor over some text, it becomes highlighted and displayed in some other color. But this wasn’t happening on the Banhammer settings screen. No matter which HTML/text I tried to select, it just wasn’t working. T’was a real mystery.. Continue reading »

PHP Code Not Displayed in Browser

[ Screenshot showing proper display of PHP code snippet ]

Recently a reader sent in a bug report about this post on bbPress. For some reason the PHP code snippets were not displaying properly in the browser. Basically, instead of looking neat and tidy as always, the code looked like a garbled mess of spaced-out nonsense. And by “spaced out” I don’t mean in a good way: there was literally like 100px of vertical space breaking up the jumbled lines of code. It was definitely a mess, so I began […] Continue reading »

Custom Widget Names with Dashboard Widgets Suite

[ Dashboard Widgets Suite - Default Widget Names ]

Quick tutorial for my Dashboard Widgets Suite plugin. This post explains how to customize the DWS widget names on the Dashboard. Normally each DWS widget displays the widget name along with “Widgets Suite” and a little gear icon that links to the plugin settings. Several users have asked if there is a way to change the text, specifically how to remove the extra text and gear icon. So this article explains how to do it as of Dashboard Widgets Suite […] Continue reading »

How to Modify HTTP Headers in the WordPress Admin Area

WordPress provides the wp_headers filter hook and send_headers action hook to add and modify HTTP requests. For front-end pages, these are ideal hooks that should be used whenever possible. Unfortunately however neither hook works on all pages in the WordPress Admin Area. After some experimentation, I found an easy solution to modify HTTP headers on any/all pages in the Admin Area.

Vanilla JavaScript Smooth Scroll

While working on the site’s 24th redesign, my goal was to simplify the UI as much as possible. As much as I enjoy lots of cool effects, I wanted the new design to be as minimalist as possible. So that meant dropping a LOT of little bells and whistles that were included in the previous design. One feature that didn’t make the cut was smooth scrolling to internal anchor targets. Like when you click a link that takes you #somewhere […] Continue reading »
