This happened with one of our individual installs and it’s happened before (but I forgot the solution) so I’m writing it down. After the upgrade to 4.7.1, the front of the sight still worked but attempts to get to wp-admin failed with a 500 error and the URL was redirecting to something with upgrade.php? in the URL. Solution Change the name of the plugin folder (I just prepend an underscore). Revisit your login URL. Run the database upgrade as prompted. You should now be in the admin zone. Fix your plugin folder name. Easy but also easy to forget.
There are a bunch of these out there but the ones I knew of didn’t quite do what was needed by the Focused Inquiry faculty involved in this project. They wanted a couple things to be possible. The ability to link to specific elements via URL and have them expand. The URL to those elements to remain consistent even if the order of the elements was changed. An “email this URL” link to enable faculty to send the URL to students Plus/Minus indicators based on expanded/collapsed. Most shortcode plugins I’ve seen either don’t have an ID for the collapse element or make it sequential (which changes if you shift the order). Neither works well for a URL that needs to be consistent. I’ve never seen one to do the email element. In my head, I made this way harder than it needed to be. It ends up being just two shortcodes- one for the collapsible container and one for the item-level elements. I found this Bootstrap snippet that did most of the functional Bootstrap stuff that I needed. I found a script to let me expand elements via URL parameters. I reminded myself what a freaking mailto link structure looked like. Now I just had to figure out what variables needed to be set in the shortcode and how the […]
Sometimes people just want a little bit of WordPress. Before hanging a left with the anth101.com site, we pruned it waaaaay down and tried to make it as simple as possible. This is a pretty solid example that WordPress can be just about anything you want if you’re willing to put in a bit of time and effort. I figure having all these things in one place will help someone else (me most likely) at some point. Hide Posts from Other Authors If you have many authors, you often don’t want them seeing a bunch of posts in the admin area that they can’t edit. Make their lives easier and hide everything else. I believe this is where I found the code. Remove Sidebar Options To further clean up the sidebar for authors, the following code removes lots of things that you don’t want students bothering with anyway. You can get lots of details on this in the codex. Go to Directly to Post, Do Not Pass Dashboard This shunts people directly to the posts area rather than going to the dashboard on login. Posts in Single Column This sets the posts to single column display to simplify writing and was found here. Purify and Rename the Post Page This chunk removes certain meta boxes and restructures the language on […]
That beautiful link-bait title and a picture of a dead leaf! That’s why I’m a social media guru. With that self-promotion out of the way . . . I found this CSS library from Una.1 It lets you apply instagram-like filters to image via CSS. Also got to have a nice interaction with Una via Twitter to clarify the license. @twoodwar :+1: its MIT so go ahead — Una Kravets (@Una) December 6, 2016 It fit a need that a professor was expressing for one of our WordPress installs so I wrapped it in a plugin/shortcode combination. The structure goes like so . . .

flickr photo shared by NASA on The Commons with no copyright restriction (Flickr Commons) It’s that time of year when you try to prove to your institution that the work you do matters . . . and I am prepared to make it rain datums.1 I’m not sure how valuable this will be to others but who knows and it helps me to write it down. Currently, my former team of 5 is now just me. So this stuff is sole mio23 and compasses everything from manual password resets to full on custom development work with faculty. Can you tell when the semester started? That’s an increase of abut 2,400 sites in about 3 weeks. I’ve got our weekly Twitter/Google Sheet spitting this out and writing it to a spreadsheet so this data was handy. I’ve been playing with logging data for a variety of reasons. For instance I now tag my rampages support emails in GMail and that logs them to a spreadsheet each night. I’m at least mostly consistent doing that because it’s a very light weight action on my part. I can then get an idea how stuff is really playing out rather than simply my perception of things (although that matters too). The chart above represents rampages email support over the last 30 days as of […]
Do you use WordPress for teaching and learning? What plugins do you recommend for a multisite install? cc @brlamb @clintlalonde @jimgroom — George Veletsianos (@veletsianos) September 8, 2016 Sparked by a tweet, this is reposted from a conversation here (thanks to Alan) but I figured that much writing ought to also be a blog post. flickr photo shared by Internet Archive Book Images with no copyright restriction (Flickr Commons) And a pre-warning, I may have overdone this . . . . As a secondary warning, I may not give the best advice. Add grains of salt as needed. There seems to be two big buckets here for me. One is managing a large multisite and stuff around that. The other is plugins that are useful when helping people build educational things. Security/Management Be careful with security plugins associated with IP addresses (Jetpack got me early on, more on that later). That can turn bad very quickly if your school shares IPs etc. iframe related – I’ve done iframes via the plugin Alan mentioned but found that getting people to do that was a hassle, I wrote a little plugin that I activate blog by blog that adds a chunk of allowed iframe parameters to the kses file. This way they keep doing things the way they think they should and […]
If you’ve got a site running on HTTPS and you try to throw in some HTTP content, the browser gets nervous. If you’ve recently made a shift to HTTPS you might notice content that was successfully embedded disappearing. If you look in the browser (right click>inspect element in Chrome), you’ll see an error like the one above. What you want in this scenario is protocol relative URLS . . . essentially a URL without the leading http/https. That lets the page load via the one protocol that matches (assuming it exists- some sites won’t supply HTTPS options).1 I ran into this problem with files we uploaded via Gravity Forms prior to the switch to HTTPS. There are a number of ways to deal with this (including search/replace at the database level) but we’re under a very heavy load at the moment and I just needed a quick fix. This solution will also allow people to do whatever they want on an ongoing basis better than a database response. This tiny little filter plugin is the result. All it does is use PHP’s preg_replace (regex) function to find any instances of HTTP or HTTPS (capital or lowercase) and remove them. I’m still amazed by regex but always end up having to spend a bit of time reminding myself of how it […]
Pre-Intervention Post-Intervention I’ve often had requests to make the admin dashboard in WordPress simpler for students (although it’s just as likely applicable to faculty or humans in general). The example in the Juxtapose box above (slide it!)1 The result above is an example based on one such request. The goal was to take the initial dashboard and reduce it down to the absolute minimum of items needed for students and to move them directly into the place they were likely to spend most of their time working (not the dashboard). The code below is all stuff that ends up living the functions file of the custom theme or could be incorporated into a plugin.2 This following code from here makes sure that the only posts an author sees are the ones they wrote. I’m not sure why that’s not the default but . . . The following removes menu items from the sidebar. It’s a combination of things I found in the Codex and in this post. It’s probable I can combine and simplify them but I haven’t taken the time to do that yet. Since there was one sidebar item coming from the theme/plugin, I wasn’t sure how WordPress would handle removing it. Turned out to be pretty straightforward. Mousing over the sidebar item got me the http://MYSITE.com/wp-admin/admin.php?page=vc-general and […]
flickr photo shared by Internet Archive Book Images with no copyright restriction (Flickr Commons) I’ve been doing a whole lot of WordPress customization lately for really widely varying purposes/people. It has been a lot of fun and it’s an option that I’m not sure has been conveyed well to our faculty. Many times, faculty are looking for a process for students (or one another) that is semi-structured. The students have options but they need help remembering to do certain things (include at least one image, consider these three topics, add a link, etc.) or they need a bit of guidance to help create uniformity of some sort. If you’ve ever asked more than ten people to answer three questions in an email then you know that virtually all the humans fail to follow directions when given the chance.1 You’ll also see the width and depth of human imagination if you ask someone to fill in a text field answering a question you really thought was straight forward.2 There are also concerns about the complexity of WordPress that we can address through custom post types and custom user roles while still allowing for a good deal of flexibility within our established constraints. This interplay of custom fields, custom post types, and usually a custom theme to display the former is probably […]
