PHP said the file didn’t exist. Except it did. file_exists() wasn’t working for a file uploaded using wp_handle_upload(). It worked for every other file, except for one provided by a German customer. I confirmed the following: The file did exist in the correct wp-uploads sub-directory The file had correct permissions The directory and its parents […]
I switched from developing using Vagrant with VVV to using the new Mac app Pressmatic. I’ve been very happy, and so has my Mac—the dev environment runs much faster and my computer has been working a lot less. Less fan noise is good. The server environment that Pressmatic uses don’t have some basic stuff that […]
I’ve been working on releasing a new version of the Constant Contact plugin for months, and it’s finally ready. The result: faster, more reliable, more features, and did I mention faster!? The Form Designer, inline editing, and EventSpot are all 100% better. I highly recommend upgrading. This plugin requires PHP Version 5.5 or newer. If […]
If you write WordPress plugins and make AJAX requests, you may be familiar the dreaded Javascript error: SyntaxError: JSON Parse Error: Unrecognized token ‘>’ Why? Why!?! What it means is that the response your code expected is screwed up because a plugin barfed PHP warnings into the admin-ajax.php ventilation system. When WP_DEBUG is on, admin-ajax.php […]
Are you a self-motivated intermediate or advanced PHP freelance developer? Want to work on taking WordPress plugins to the next level? I want to work with for someone who is interested in contract or hourly work to work with on GravityView, IDX+, and my other WordPress plugins. There is lots of work to be done. […]
In developing deeper integration with the Customizer functionality of WordPress, I wanted to use a custom icon for my IDX+ plugin’s widgets. By default, WordPress defines a list of icons using their dashicons icon set and tries to guess the best icon for your widget based on the CSS class of your widget. Check out […]

GravityView integrates with the popular Gravity Forms plugin and makes it easy to display entries on your website. Embed Gravity Forms entry data in a post or a page Control what data is displayed using […]
Almost ready. It’s been a long haul for the new version of the Constant Contact for WordPress plugin. I started working on it before Constant Contact finalized their new API, so let’s just say it has been a major undertaking 🙂 Now I need help getting it ready for release! The new Constant Contact WordPress […]
WangGuard is a great plugin for blocking spam registrations. Without it, this site gets about 50 per day. No good! I did encounter an issue, however: The <![if !IE]> tag was showing on my registration form for some reason. The code WangGuard adds inside the tag is used to generate a “honeypot” section: spam bots […]
Yesterday a crucial security flaw was discovered in the Gravity Forms Directory plugin and fixed immediately. Version 3.5.4.3 was released and takes care of the issue. __Please update immediately__. For the security of the users still running older versions, we can’t go into what the flaw was, but it had to do with viewing Gravity […]
Easy Digital Downloads defaults to using 10 results per page when using the get_products() method. You can modify this default using the edd_api_results_per_page filter. Here’s how to fetch all products at once: $EDD_API = new EDD_API; // Force EDD to show all the downloads at once. add_filter(‘edd_api_results_per_page’, ‘modify_edd_api_results_per_page’ ); // Get all the EDD products […]
My bank just got bought by another bank, and this is the beautiful egg they laid on me: pink and green zebra stripes. Compare that to Simple.com. Any questions?
It’s really simple to use Google’s Display Advertising code, so I thought I’d share how. To enable the new GA features: Check the “Show Advanced Settings” Under “Advanced Settings,” check the checkbox for “Host ga.js locally:” In the text field that appears, enter: //stats.g.doubleclick.net/dc.js Note: The missing http and https is intentional – if your […]
Apple has a deep-seated diversity problem. In the 30 Years of Mac mini-site, a thoughtfully prepared homage to the history of the Macintosh and the people who use it to create, there were four women featured out of the twenty-eight profiles. One of the women featured, Noemi Trainor is an educator, a role women are […]
Working with Google Maps v3 is way fun. If you’re a masochist. It seems like there’s no easy way to set the width of an InfoWindow. You can set the minWidth parameter, but that does nothing. If you have content that exceeds the InfoWindow window, you get this: a scrolling box. That’s terrible. The solution […]
I’m going to be attending WordCamp Phoenix 2014 from the 17-19th. If you see me there, say hi! I’m looking forward to meeting some plugin developers and other people I recognize from the attendance roll. I’m also looking forward to expected 70° temperatures.
After reading Pippin Williamson’s post about gettext speed issues, I wanted to learn more. My IDX+ plugin has 815 translatable strings, and I was worried that it was having a performance impact on the plugin. I created a test that looped through different methods of outputting and printing strings to try and determine their relative […]
I’m in the process of setting up a store using the Easy Digital Downloads plugin. It’s been a good process so far and I’ll have more posts about it. While I was setting up the checkout process for testing, I wanted to be able to use test payments but keep the option hidden to non-admin […]
SEODenver.com is now katz.co Katz Web Services hasn’t been doing SEO for years – I’ve been focusing on making great WordPress plugins (such as IDX+) and I have been disenchanted with the SEO industry. So it was time to move the SEODenver.com domain to katz.co. I’m looking forward to writing more blog posts now that […]
