How to develop your own WordPress CRON job properly and ensure it actually runs

Hello! In this post we will be walking through how to interact with the WordPress Cron system. We will delve into how to establish your scheduled jobs properly using the built-in WordPress cron system, with no other external interactions such as the OS cronjob system. This will be useful for WordPress plugin developers as in order to develop a plugin that utilizes reliable scheduled tasks, you need to accommodate many different types of web hosting environments. What is CRON? In linux, this would be a command line utility that allows the end user to schedule jobs to run at specific days and times on a repeating basis. You can write your own script and have the operating system run it on a nightly basis. Systems Administrators use this often for things like backups, integrity checks and a wide array of use cases. What is WordPress CRON? Taking the same concept […]

How to push your single post or page content with this new WordPress plugin

Hello! There is quite a bit of documentation with how to scale your WordPress site for enterprise. Additionally there are quite a few enterprise WordPress hosting solutions that allow you to “stage” your content on staging sites with automated methods to push or clone the staging site (once an internal approved process gives the thumbs up perhaps) to the live / production website. These systems are great and not only sanitize and streamline the publication process of your website, but also increases the security and containment of any issues that may come up with your website. The live site can be further locked down and restricted as a result of this type of process because people (administrators, contributors) no longer need to be logging in and interacting with the live production website. All of it can be done on a more private staging site. For many people this type of […]

How to import your Zoom Webinars into WordPress as custom content

Hello! Now, more than ever, companies businesses and individuals are leveraging web based collaborative tools like Zoom. Whether it be for company meetings, training sessions or sales seminars, the idea is to use video conferencing technology to replace in-person interactions. Zoom has emerged as a leading player, being positioned favourably at the right point in time to offer reliable video conferencing services for a variety of uses. One of the more common requests as web development agency, is to integrate the ability to “import” Zoom webinars for a business into their website. What once may have been an Eventbrite integration has now transitioned to a remote model of interaction. At Shift8, we have created a WordPress plugin to pull Zoom webinar events into WordPress as custom content. This can then be manipulated by your theme or a custom post grid perhaps. Why would you want to import Zoom Webinar’s into […]

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 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 inject advanced custom fields into your WPBakery post grid

Hello! Yes of course WPBakery / Visual Composer is bloated. Absolutely correct its more ideal to simply create your own page template with a custom WordPress query and design your own post grid from scratch. For smaller budget WordPress projects where time is money, it is sometimes ideal to go the post grid route. Why not? The customer wants the designed and customized end result but they have a restricted budget. WPBakery (aka “Visual Composer”) does save time in these scenarios, and there’s something to be said about applying customized CSS and jQuery to customize and tailor the vanilla packaged look and feel that these types of WordPress bundled solutions usually bring to the table. All that said, the point of this post is to describe how to properly inject custom ACF fields (advanced custom fields fields) into your post grids. Why would you want to do that? Well if […]

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 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 […]
