Creating dynamic sliders with Soliloquy for free

I wanted to create a simple dynamic slider using Advanced Custom Fields, but Soliloquy does not have this option out of the box. After poking around the source of Soliloquy I found the filter soliloquy_custom_slider_data which lets us add our own slider data. Here is the required code to dynamically generate a slider. (This code is not ACF-specific, you can use any data source.)

Your slider will be available using the shortcode:

[soliloquy type="frontpage"]

The code to generate this dynamic slider:

add_filter('soliloquy_custom_slider_data', function($data, $atts, $post) {

    //Bail early if not our slider type
    if(isset($atts['type']) && $atts['type'] !== 'frontpage') {
        return $data;

    $data_dynamic = [
        'id' => 0,
        'slider' => [
            //This is where you enter all your dynamic slides!
            //72 and 73 below are the IDs of the image attachments used in the slider. 
            72 => [
                'status' => 'active',
                'id' => 72,
                'attachment_id' => 72,
                'title' => 'Image title',
                'link' => '',
                'alt' => 'Alt text',
                'caption' => 'Caption',
                'type' => 'image',
                'linktab' => 0
            73 => [
                'status' => 'active',
                'id' => 73,
                'attachment_id' => 73,
                'title' => 'Image title',
                'link' => '',
                'alt' => 'Alt text',
                'caption' => 'Caption',
                'type' => 'image',
                'linktab' => 0
        'config' => [
            //This is the general slider config
            'type' => 'default',
            'slider_theme' => 'base',
            'slider_width' => 1080,
            'slider_height' => 400,
            'transition' => 'fade',
            'duration' => 5000,
            'speed' => 400,
            'gutter' => 20,
            'slider' => 1,
            'aria_live' => 'polite',
            'classes' => [
            'title' => '',
            'slug' => '',
            'rtl' => 0

    return $data_dynamic;
}, 11, 3);

I am using Soliloquy Lite, although I’m sure this works with the paid options as well. You can also easily create multiple dynamic sliders, each pulling data from different sources.

Increase / add swap space on EasyEngine

EasyEngine provides you with 1GB of swap space by default, but sometimes you’d like a little bit more. Here is how you can increase the swap space:

Edit /etc/dphys-swapfile and set the following:



dphys-swapfile swapoff
dphys-swapfile setup
dphys-swapfile swapon

That’s it! Verify your new swap space with htop or top

Add custom CSS style to Advanced Custom Fields WYSIWYG field

Example of adding styles from a theme. The code below works on frontend (if you are using acf_form()) as well as in the backend.

add_filter( 'tiny_mce_before_init', function($mce_init) {
  $content_css = get_stylesheet_directory_uri() . '/your-custom-css.css';

  if (isset($mce_init[ 'content_css' ])) {
    $mce_init[ 'content_css' ] = "{$mce_init['content_css']},{$content_css}";

  return $mce_init;


Bose QC25 Equalizer preset

The Bose QC25 are great-sounding headphones. However the bass is way too heavy, which results in a muddled midsection. By bringing the lower frequencies down a bit and increasing high frequencies, you will get a much more balanced sounds profile. Simply tweak your equalizer according to the graph above and to your personal preference.

If you use foobar2000 you can download the exact preset here for the foo_dsp_xgeq component here.

Building the right administration interface for every user

WordPress Stockholm meetup group, January 2017

When building websites a lot of work is put into the frontend of the site – with good reason! But often the experience for content editors and site administrators isn’t given as much thought. However WordPress has a wide array of tools to easily make great admin interfaces.

In this talk we’ll take a look at the ecosystem of administration tools available for WordPress, as well as the different types of users that are likely to use the backend of the sites you build.


Migrating a WordPress Site From HTTP to HTTPS with WP-CLI

It’s as easy as:

Take a backup

wp db export

Test rewriting from HTTP to HTTPS

wp search-replace '' '' --dry-run

If everything is looking good, it’s time to rewrite:

wp search-replace '' ''

Some tutorials recommend adding the --skip-columns=guid flag. The train of thought is that old posts will be visible to RSS readers as new ones. I don’t think this is a big problem, and it’s much cleaner to not keep non-SSL urls in your database. It can also cause issues if you are using the GUID field to grab image urls/ids from attachments. (It’s a very popular way of mapping a URL to an attachment ID). With that in mind, I find it’s best to omit this flag.

Disable GitHub API in Composer to improve speed

If you are using GitHub repositories in Composer, you might notice that it takes a long time to run composer update. This is because Composer uses the GitHub API in an effort to improve performance. Unfortunately, GitHub API is very slow and you might need hundreds of calls for a single repo, depending on the number of tags. You can disable this behaviour by specifying the undocumented no-api flag in Composer. In composer.json, add it like this:

    "type": "vcs", 
    "url": "", 
    "no-api" : true 

This will make Composer check out the repository via Git instead, usually improving composer update times by 2-3x.
