How to bulk update all WordPress pages or posts

Hello! Sometimes its necessary to perform mass or automated actions against your WordPress content. Reasons for this can vary, but in our scenario there was a bug in a plugin relating to translated content via WPML where afte a fix / plugin update was applied, resolving the content errors was as simple as re-saving an existing post (with no changes). Normally this wouldn’t be a problem but what if your site has over 1,000 pages or posts? Doing those one at a time , or even via the “Quick edit” method can be tedious and resource-taxing (both in-person and server resources!). Alternatively, what if you needed to update a byline in the post content, or standardize a title format for your posts? The reasons can vary again ,but I thought it might be helpful to include an automated process using a method called “bootstrapping” WordPress. What this really means is […]

How to sanitize and reset all WordPress user accounts with linux shell scripting and wp-cli

Hello! There are several key best practices insofar as how to deal with security intrusions, including but not limited to restoring from backups on a clean server. In this article, I will be going over how to create an automated shell script that completes the following actions across multiple WordPress sites on your linux server : 1. Sanitize user and group permissions 2. Sanitize WordPress core admin and include files 3. Update WordPress Core 4. Update All installed plugins 5.

I will touch on each of the above items including the shell script snippets that are required to implement each. At the bottom of this article I will share the entirety of the shell […]

How we created our own free content delivery network for WordPress users

Try out our Free CDN service by installing the Shift8 CDN WordPress pluginHello! We thought it would be an interesting challenge both from a DevOPS perspective as well as a web development and integration perspective to create our own fully managed content delivery network. Utilization of the network is geared specifically for WordPress users. The idea being to give users a dead simple way to leverage geographic CDN endpoints across the globe by simply installing a WordPress plugin and activating with the click of a button. You never have to leave your site to register on a 3rd party website, you never have to set up API keys by hand or troubleshoot problems. We wanted it to be simple. And to work! There are many components that need to be integrated and ultimately tied together in order for a system of this magnitude to work. I’ll try to break it […]

How to block your WordPress site from being scanned by WPScan with Nginx

Hello! First and foremost, why would you want to block WPScan from probing your site? Well we all know that security through obscurity is a bad practice. That said the risks of malicious activity on your site is undoubtedly heightened through many points of information disclosure that is freely available to parse and organize to make an accurate security risk assessment of your WordPress site. This type of information is easily attainable through automated scanners like WPScan. Tools like this scan for version tags in readme files, file size fingerprints and meta tags to determine not only the version of WordPress you are running but the version of each of the plugins you have installed. Why is information disclosure bad? Some would argue its not bad. Others would also point out that a 0-day WordPress core or plugin vulnerability could mean that minutes and hours of circumvention or lowered risk […]

How to cache queries to admin-ajax.php in WordPress to improve performance

Hello! Working with wordpress for a while now, we noticed that many actions, whether administrative in nature or building a WordPress query on the front end, are dependent on the built-in admin-ajax.php or WordPress AJAX API. Since many 3rd party plugins depend on this Ajax API to dynamically push and pull data, it is unfortunately a common occurrence to have the performance of a site impacted when many AJAX API calls are happening. One of the tell tale signs of admin-ajax.php performance issues can be seen when inspecting the network connections of rendering a particular page on your WordPress site. If you filter “admin-ajax.php” in your network tab of the developer console in your browser, you should see clearly the admin-ajax.php POST that may be taking too long. In our experience, some post grid plugins that make it easy to render a grid of posts on your page heavily rely […]

How to protect WordPress media files and only allow the users who uploaded them to view

Hello! In the past we have written about how to protect your WordPress media files. In the past exercises we utilized a strategy to set a session cookie with encrypted details that can be read and validated at the http service (i.e. nginx) as well as application (php/wordpress) level. Since then we have refined this process to be much more secure, flexible and efficient. We have abandoned the cookie validation process for verifying the request before serving it and replaced it with a slightly more complicated but much more secure method. First before getting into the details, why would we want to protect WordPress media files? Well the answer depends on what sort of site you have and what you are trying to do, obviously. In our scenario, which isn’t necessarily unique, we have end-users that register for an account in order to check out of a Woocommerce store. We […]

How to implement a government ID verification system with Woocommerce and WordPress

  Need this implemented on your site? Click here and fill out our quote form!   Hello! There are many reasons why your Woocommerce store may need a system to accommodate verifying the identity of your customers. Depending on what your selling and the local or federal laws that are in place, having the identity of your consumer verified may be needed for liability or compliance reasons. Additionally under certain conditions within your Woocommerce store (such as orders over a certain amount of money), validating the identity can dramatically reduce the risk of fraud and fraudulent transactions on your site. I’m going to go into details with how to implement a system into your Woocommerce store that will accommodate the following : Provide a section within the Woocommerce “my account” area for end-users to upload a digital image of their ID Add a new field for the user details to […]

How to make bulk changes to WordPress Woocommerce product attributes with PHP

Hello! Sometimes its necessary to make site-wide changes to WordPress posts in order to save time and programmatically propagate changes without having to edit each post one at a time. For bulk manipulation of WordPress data, it is sometimes effective to write a command line PHP script to hook into your WordPress environment and execute changes. One of the main advantages with executing these types of functions on the command line as opposed to a web based interaction is you are not subject to the same execution and other timeout restrictions for web based requests. This means that a command line PHP solution can run longer, which is sometimes needed for complicated efforts. In our example, we will break down the PHP Command line script, how to safely and securely hook into WordPress to take advantage of all the built in functions, and update all the products in our WordPress […]

WordPress plugin to remotely manage and automate multiple WordPress sites

Hello! Being a Toronto based web design and development agency means that we interact with a significant number of WordPress sites. This tends to happen when a project starts (obviously), but often continues after a site is launched. This is something that we offer along the lines of “post launch maintenance”. By no means once a site is launched is our job done, and I’m sure a lot of other people in the industry can relate. If you follow the WP Vulnerability database notifications (if you don’t, you should), then you will see many notifications per day with various plugin or core vulnerability announcements. For this reason, among many others, we found ourselves struggling to automate and streamline the management of many client websites. We’re a fan of automation and have published articles on our efforts to integrate WordPress with Jenkins. With that particular plugin, we were able to automate […]

How to push your WordPress site with a simple bash shell script and integrate it with Jenkins

Hello! Previously we gave an overview of our new WordPress plugin to integrate your Jenkins build process within the WordPress administration area. The previous post gave an overview of how to set up Jenkins as well as how to set up the WordPress plugin. Where we stopped short is actually integrating the build script within Jenkins that the WordPress plugin triggers! Why you need a build script for Jenkins to trigger when pushing WordPress from staging to production The answer to this question may be obvious to some, but not all. The use cases may vary from scenario to scenario, but the ideal solution is to implement a solution that cleanly copies all files as well as the database from your staging or development environment over to your production or live environment. Where it gets slightly complicated is things like your site URL may change as well as your database […]
