WordPress is_ssl() doesn’t work behind some load balancers

WordPress has a function is_ssl() that it uses to check whether a page is loaded with the HTTPS protocol, so that it can use the same protocol to load scripts, stylesheets, and other assets. It relies on the web server giving it a couple of clues, but when your website is hosted behind a load balancer, those clues aren’t always available. In particular, websites hosted by Network Solutions get no clues at all when pages are loaded over HTTPS.

Stop Events Manager from cropping thumbnails

Events Manager gives you a special placeholder that you can put into its templates, for inserting the event’s “featured image” into lists and single event pages. If you want to insert a thumbnail, it uses the timthumb script to create one on the fly — but it crops that thumbnail. Here’s how to use the WordPress uncropped thumbnail (or any registered image size).

Events Manager locations map with directions

Events Manager is my events and bookings plugin of choice for WordPress, because it is very flexible, easy to integrate into a theme, and has hooks galore for customising to suit almost any requirement. Its location map doesn’t offer a way to provide directions, however. So, here’s how to replace the Events Manager locations map with WP Flexible Map and get a directions link on location pages.

Repair WordPress image meta

There are times when things just go wrong. I had one of those times the other day. The pressure was on to deliver a project, and there were bits of PHP and CSS and JavaScript flying everywhere here at WebAware Central. And so it happened: I wiped the image attachment meta data in the WordPress database.

Get custom fields for WordPress post

WordPress lets you store custom fields on your posts (and pages, and custom post types that allow it). However, it gives them to you in a rather inconvenient manner, with your values mixed in with its own special fields and any plugin’s special fields, and with values in an array. Here’s how to easily deal with that.

Stop turning off CURLOPT_SSL_VERIFYPEER and fix your PHP config

As Pádraic Brady points out in a recent article about PHP security, there’s a whole lot of misinformation about how to deal with the error “SSL certificate problem, verify that the CA cert is OK” from curl. Nearly everyone advises that you turn CURLOPT_SSL_VERIFYPEER off (in fact, countless comments on the PHP manual page for curl_setopt tell you this). This is bad, because it allows your nice, encrypted stream of confidential data to be silently highjacked by a bad guy. Don’t do that! Instead, just fix your PHP installation so that it doesn’t get that error.
