Load Gravity Forms stylesheets in page head

Friday, August 21st, 2015

Gravity Forms normally loads its stylesheets in the page head, where they belong. It does that only on pages which have forms, which is nice. If you use a widget to host your form, however, it can’t detect that until it renders the widget… too late to load the stylesheets in the head. At that point, it just pulls them directly into the page body.

Disable scroll wheel on Events Manager location maps

Saturday, August 15th, 2015

Events Manager is a really nice, easy to customise plugin for showing events on WordPress websites. One gripe I always have with it is that the location maps zoom when you use the mouse scroll wheel, something I always turn off when I add a map to a page. Here’s how to fix it.

Hack a WordPress plugin AJAX action

Monday, July 13th, 2015

Customising the AJAX output of WordPress plugins can often be a breeze, when the authors oblige other developers by peppering their code with action and filter hooks. But if they don’t, you can always fall back on hacking the plugin’s AJAX action.

Fix broken tables in twentyfifteen WordPress theme

Saturday, December 27th, 2014

WordPress 4.1 brings with it the twentyfifteen theme, which I find to be a rather nice blog theme. Unfortunately, it adds a new wrinkle to any tables on your website — often breaking them! Here’s the simple fix.

Sort WooCommerce products first in search results

Thursday, December 18th, 2014

When shoppers search a WordPress website, you want them to find products first before listing any articles and pages. And it’s surprisingly easy to achieve, with a simple filter hook.

Set the tab size on GitHub, Gist, and Bitbucket

Wednesday, September 3rd, 2014

I indent with tabs. There, I said it. Viewing my code (and that of other tab indenters) on GitHub, Gist, or Bitbucket can be annoying because the default tab size in the browser is equivalent to 8 spaces. Modern browsers let you change that through CSS, and here’s some bookmarklets that do just that.

Move Gravity Forms field labels above input fields

Saturday, July 19th, 2014

Gravity Forms has some nice compound fields to make it easy to accept things like names, addresses, and credit card details. One annoying thing it does, though, is put the labels for the input fields below them instead of above them. Here’s how to move Gravity Forms field labels above input fields where most people would expect them to be.

Load Gravity Forms scripts for custom field

Monday, June 30th, 2014

Gravity Forms is a very easy to use yet flexible tool for building forms in WordPress. It uses quite a bit of JavaScript and custom CSS, so it’s careful to only load its scripts and stylesheets when needed. But if you put a form into a custom field, e.g via Advanced Custom Fields, how will Gravity Forms know it needs to load them?

Remove register link from WordPress wp-login.php

Tuesday, April 29th, 2014

I recently had to enable user registrations on a WordPress multisite, so that shops on that site could allow customers to register. I don’t want users to register any other way, only through specific applications on specific subsites. Enabling user registrations adds a “register” link to the wp-login.php script page. That invites trouble!

Remove SKU from WooCommerce front end

Friday, April 25th, 2014

If you need to have SKUs on products in WooCommerce, but don’t want to show them on the front end, you can’t just untick an option in the WooCommerce settings: you can either have and show SKUs or not have them at all. So here’s a quick snippet that lets you have them, but remove them from the front end.
