Re: Edit WordPress Posts and Postmeta in the Customizer

I couldn’t reply to Jeff’s comment on Sarah’s WP Tavern post because of a Jetpack problem, so I’m posting it here: With the Front-end Editor using the Customizer as a framework, I wonder if the interface will look similar to this experiment? I hope not. This plugin is really a prototype to demonstrate how the […]

Failures related to the WordPress APC Object Cache plugin

On a site for a newer X-Team client, APC was previously chosen as the object cache plugin. This has caused some headaches due to APC not being available while in CLI mode, rendering WP-CLI mostly broken: any commands which change parts of the database which get object-cached won’t appear until the cache gets invalidated, which may […]

Easily turn any webcam image into video on an OS X Dashboard widget

I have a few webcams on my network which I can access via URLs like http://198.162.1.30:8080/cam.jpg. Here’s a handy little bookmarklet (pagelet?) which allows you to turn any such webcam URL into live video (here, 1 fps): data:text/html,<img src=”http://198.162.1.30:8080/shot.jpg” onload=”var img = this; setTimeout( function(){ img.src = img.src; }, 1000 )”> Paste this  data:  URL into […]

Regularly cleaning up /tmp on a DreamHost VPS

I checked the server error log, and I saw entries like: ModSecurity: Input filter: Failed writing X bytes to temporary file Looking at my /tmp directory it contained 128MB of data. Apparently ModSecurity tries to prevent the […]

Re: Sharing Sidebars Across a Multisite Network

In a post yesterday at WebDevStudios about “Sharing Sidebars Across a Multisite Network”, I was reminded of a workaround that I had to put into the Widget Customizer plugin. There is this unfortunate condition inside of the core wp_get_sidebars_widgets() function: // If loading from front page, consult $_wp_sidebars_widgets rather than options // to see if wp_convert_widget_settings() has made […]

Revelations about filter_input

WordPress has the unfortunate legacy situation of having to force input variables to be “magic quoted”, something which has been deprecated in PHP for some time. So when you are working with data passed from the user, you have to run those input variables ($_GET, $_POST, $_REQUEST) through stripslashes(), which is really annoying. At least […]

List of Functions Removed from WordPress 3.6 RC2 since Beta 3 (and Added too)

On an ongoing client project at X-Team, since the site was to launch in the summer we took the initiative to build a new site on WordPress 3.6 trunk “knowing” that it would be released before then, and so we could utilize the new Post Formats UI and functions that went along with it. Alas. […]

Do not change the default timezone from UTC in WordPress

I discovered something a bit surprising about WordPress related to timezones: WordPress explicitly sets and expects the default timezone to be UTC (in settings.php) and the date/time functions sometimes rely on the fact that the default timezone is UTC. For instance if you do date_default_timezone_set(get_option(‘timezone_string’)) and then later try to get a GMT timestamp from get_post_time() […]
