	};

}

document.getElementById('txtFileUpload').addEventListener('change', upload, false);

function upload(evt) {

var data = null;

var file = evt.target.files[0];

var reader = new FileReader();

reader.readAsText(file);

reader.onload = function(event) {

var csvData = event.target.result;

var data = Papa.parse(csvData, {header : true});

console.log(data);

};

reader.onerror = function() {

alert('Unable to read ' + file.fileName);

};

}

WPML – Going multilingual with WordPress

Getting started

“WPML (WordPress Multilingual) makes it easy to build multilingual sites and run them. It’s powerful enough for corporate sites, yet simple for blogs.” – WPML

I have been running and setting up multilingual websites for more than 12 years. WordPress and related integrations have gladly come a long way to make our life’s a lot easier.

For basic content WPML is almost plug & play, but I do see more and more sites / customers struggling with more complex setups. WPML is one of the most popular multilingual plugins and is used on x00.000 of websites.

Just so you know, WPML is a commercial solution!

Settings for almost everything

The amount of settings has increased a lot over the years and offers possible solutions for almost any content / plugin setup.

But for more complex setups, I would suggest to hire a professional to look over the settings or study the plugin documentation carefully.

Especially with a lot of content, it can quickly increase problems and the need to revisit specific content over and over again.

How to translate

WPML lets you translate any text that comes from themes / theme frameworks (DIVI, Elemetor, Gutenberg …), plugins, menus, slugs, SEO and additionally supported integrations (Gravity Forms, ACF, WooCommerce …).

You can translate content internally for yourself, using translation management to translate with an internal team of translators or get help from external translators / translation services.

The latest version also offers AI translations, which allows you to get a decent start for most of your content.

In addition to the above, WPML String Translation allows you to translate texts that are not in posts, pages and taxonomy. This includes the site’s tagline, general texts in admin screens, widget titles and many other areas.

Is it worth its money

Well, I am a bit biased. I have not looked much at other solutions for the past 5 years, as it offers all I really need.

I have used it on projects from 2 to 15 languages and it scales nicely. At least with proper hosting attached!

Anything can be tweaked through the API, Hooks and custom integrations. I have build additional WPML tools for my customers, to streamline some of the repeating / boring tasks.

Their support is responsive and the forum already provides a huge amount of answers to most of the questions that might come up.

If you develop / maintain multiple customer websites with multilingual content, the investment is quickly
amortized. I do offer WPML to my maintenance package customers, maybe something to consider ;)

Its an essential solution in my WP toolbox.

WPML 4.5

WPML 4.5 is on its way and will include a “Translate Everything” feature, among other fixes and enhancements.

Translate Everything allows you to translate all of your site’s content automatically as you create it. You can then review the translations on the front-end before publishing.

cubicFUSION Themes for Klaro!

“Klaro [klɛro] is a simple consent management platform (CMP) and privacy tool that helps you to be transparent about the third-party applications on your website. It is designed to be extremely simple, intuitive and easy to use while allowing you to be compliant with all relevant regulations (notably GDPR and ePrivacy).”

The tool is developed by KIPROTECT and can be found on Github.

Black & White

As I integrated Klaro on a couple of websites so far, I decided to make my work a bit easier and start building some basic clean themes for it.

I have a basic white and black&white theme so far. The download includes a testdrive folder, to showcase the themes. The white theme is also used on this website ;)

I really hate those standard consent management modals, that integrate badly into the website native design.

Klaro does a good job allowing to override its core theme and makes it a bit more pleasant. We do have to live with those modals from now on ;)

The themes are Sass-based and provide easy configuration options.

Enjoy!

cubicFUSION Themes for Klaro! @ Github

Klaro! Tweaks

Klaro is still missing some things, will collect some workarounds here for you to play with.

Missing events for consent modal open / closed …

Updates: Github Discussion
– 0.7.10 also adds custom callbacks to services (onAccept, onDecline, onInit) NICE!

Used a simple MutationObserver to do some magic for now, without diving into the core Klaro code for now. I am sure they already have an event listener or watcher setup.

var cm_event = document.createEvent('Event');

cm_event.initEvent('consentModalOpen', true, true);

document.addEventListener('consentModalOpen', function (e) {
    console.log("consentModalOpen")
}, false);
	
document.addEventListener("DOMContentLoaded", function(e) {        

        var cm_target 	= document.getElementById( "klaro" ),
			cm_visible 	= false;	

        var observer 	= new MutationObserver(function(mutationRecords) {          

            if(document.querySelectorAll('#klaro .cookie-modal').length > 0 && cm_visible == false){	
                cm_visible = true;
                document.dispatchEvent(cm_event);
              
            }else{
                cm_visible = false;
            }
        });

      observer.observe(cm_target, {
        childList: true, 
        subtree: true, 
        characterDataOldValue: true 
      });
});

var cm_event = document.createEvent('Event');

cm_event.initEvent('consentModalOpen', true, true);

document.addEventListener('consentModalOpen', function (e) {

console.log("consentModalOpen")

}, false);

document.addEventListener("DOMContentLoaded", function(e) {

var cm_target = document.getElementById( "klaro" ),

cm_visible = false;

var observer = new MutationObserver(function(mutationRecords) {

if(document.querySelectorAll('#klaro .cookie-modal').length > 0 && cm_visible == false){

cm_visible = true;

document.dispatchEvent(cm_event);

}else{

cm_visible = false;

}

});

observer.observe(cm_target, {

Welcome Dashboard with Gutenberg – cubicFUSION Admin Enhancer 0.2.5

What’s new / What changed ?

Admin Enhancer is the first free plugin released under the cubicFUSION brand. The plugin is still work in progress, but a tool that is already used within some of my client projects. I am using this plugin to centralise things I love & need, when sending out a finished website or project.

NEW: DASHBOARD GUTENBERG / DASHBOARD TEMPLATES
NEW: ADMIN TOOLBAR
UPDATE: SHORTCODES

Addons included …

This version includes a new addon “GUTENBERG DASHBOARD“, that allows you to build a White-Label Admin Dashboards using the Gutenberg Editor.

It integrates with the SHORTCODES addon and allows to drop in the dashboard widgets via its own Gutenberg Block.

The Block provides settings to overwrite CSS from the admin widgets, allowing you tweak them a bit — for better visual integration. The Dashboard template itself can be tweaked using CSS and Sass via SCSS now 😉

I am also releasing the first integration of the “ADMIN TOOLBAR” addon, which allows you to tweak some of the admin toolbar and footer options (Hide WP Logo, Hide Toolbar on Frontend, Hide Menu Items ..)

Already working on 0.3 … ENJOY!

2020: WordPress Admin White Label Solutions ( Personal Favorites )

I am always looking for easy ways to white label the WordPress administration for myself and my clients. A nice personal touch for each project and an easy way to declutter the interface.

These are my personal favorites, that I use on a regular basis.

Admin Themes / Login Page

There are a lot of solutions out there, but many break easily and are really heavy to load. Some of these solutions I tried also break easily on new WordPress Upgrades. The first two below are currently my favorites.

Slate Pro ( Commercial )
“Slate Pro is a powerful WordPress admin theme plugin that reimagines WordPress with a clean and simplified design. White label your WordPress install with custom colors, a custom login screen, custom admin branding, and more. Slate Pro is now multisite compatible! Network activate to control the look of all sub-sites.”

Slate Pro is a clean and simple admin theme, that does not try to alter the interface completely. Small changes that make a difference. Color adjustments, logos, simple menu & widget enhancements and login page tweaks. Compared to other solutions it has been a stable experience, even after multiple WordPress Updates.

This is an install and enjoy solution!
Kodeo Admin UI ( Free – Open Source )
“Kodeo Admin UI turns your WordPress backend into a clean and modern user interface. All elements are well designed and arranged for the best user experience.”

Kodeo is another clean interface, that goes further than Slate Pro. Many areas of the admin theme have been changed. It works well with most 3rd party plugins, but I have had problems with some plugins doing their own little interface tweaks.
With Kodeo your WordPress Admin completely transforms and gives it a really modern & clean look.

This is an install and tweak solution! You might need to trim certain CSS properties to make it work for everything.
Material WP ( Commercial )
“Material Design version of the WordPress Admin Interface”

I have used this once or twice in the past. Its more of a honorable mention. The admin theme transforms the interface completely, but can feel sluggish on slower servers. It has an impressive set of options and gets regular updates.

This is again an install and tweak solution! It works with most of the 3rd party plugins and Gutenberg, but some things might need to be trimmed by hand.

Menu Editors & User Groups

When sharing the administration with your customer, you often need to make it as simple a possible for them. Depending on your setup, the menu becomes cluttered and overwhelming really fast.

I often trim menus for each user role, to make only those options accessible that are really needed.

Admin Menu Editor Pro ( Free / Commercial )
This tool has been part of many of my projects and has been a solid solution for years. You can hide & move menus, create new menus, tweak menus by user role, hide plugins and also tweak the admin toolbar with an extra addon.
Worth every penny! There is a free version available, that might just provide enough functionality for your next project.
Groups ( Free )
“Groups is designed as an efficient, powerful and flexible solution for group-oriented memberships and content access control. It provides group-based user membership management, group-based capabilities and access control for content, built on solid principles. Groups is light-weight and offers an easy user interface, while it acts as a framework and integrates standard WordPress capabilities and application-specific capabilities along with an extensive API.”

This plugin allows you to add new user groups easily and can tie into the plugin above.

User Profiles

When sharing the administration with multiple users, its always nice to add some personality to the user profiles as well.

WP User Profiles
“WP User Profiles is a sophisticated way to edit users in WordPress.”

The plugin provides other small addons, like WP User Avatars. Neat plugin to tweak admins, editors and other users.

Admin Dashboard Replacements

cubicFUSION Admin Enhancer (Free)

This is a new plugin I am currently working on. The current shortcodes addon can help you integrate dashboard widgets into the dashboard builders below.

I am also working on my own dashboard builder, that requires none of the solutions below and builds upon WordPress core functionality.
Dashboard Welcome for Elementor (Free)

“Dashboard Welcome by PowerPack Elements gives you full control over the WordPress welcome panel using Elementor.

You can personalize the dashboard with content and design built with Elementor. You can add heading, contact information, form, video, images, affiliate links, etc.

While the above plugin is free, you need a Elementor Pro License to use it!
Dashboard Welcome for Beaver Builder (Free)

“Welcome by Beaver Addons gives you full control over the WordPress welcome panel using Beaver Builder.

You can personalize the dashboard with content and design built with Beaver Builder. You can add heading, contact information, form, video, images, affiliate links, etc.”

Even though the plugin above is free, Beaver Builder is a commercial plugin!
Divi Dashboard Welcome ($22)

“Divi Dashboard Welcome gives you control over the WordPress Dashboard Welcome screen …”

The plugin requires the Divi Page Builder. Both plugins are commercial!

Enjoy

Have you heard of GatsbyJS?

Gatsby is a free and open source framework based on React that helps developers build blazing fast websites and apps.

What they have to say …

Go Beyond Static Websites. Get all the benefits of static websites with none of the limitations. Gatsby sites are fully functional React apps so you can create high-quality, dynamic web apps, from blogs to e-commerce sites to user dashboards.
Use a Modern Stack for Every Site. No matter where the data comes from, Gatsby sites are built using React and GraphQL. Build a uniform workflow for you and your team, regardless of whether the data is coming from the same backend.
Load Data From Anywhere. Gatsby pulls in data from any data source, whether it’s Markdown files, a headless CMS like Contentful or WordPress, or a REST or GraphQL API. Use source plugins to load your data, then develop using Gatsby’s uniform GraphQL interface.
Performance Is Baked In. Ace your performance audits by default. Gatsby automates code splitting, image optimization, inlining critical styles, lazy-loading, and prefetching resources, and more to ensure your site is fast — no manual tuning required.
Host at Scale for Pennies. Gatsby sites don’t require servers so you can host your entire site on a CDN for a fraction of the cost of a server-rendered site. Many Gatsby sites can be hosted entirely free on services like GitHub Pages and Netlify.

What I have to say …

While researching some popular static site generation tools, GatsbyJS comes up often. I have played with NuxtJS and Hugo in the past, but what I REALLY like about GatsbyJS is the plugin / modular system. You can build your website with plain-old React and CSS styles, but make your development more efficient by adding node_modules.

Also being able to import any data source with ease, using GraphQL, is amazing. And when it comes to content management, you can easily hook a headless WordPress or Drupal setup into the mix and consume their REST APIs :)

I am not switching my own website to GatsbyJS anytime soon, but its another tool in my toolbox for future project consideration !

There are many tutorials on Youtube about getting started, maybe something to consider for the next freetime testdrive ;) Enjoy …

Screenshot Service with Node.js

Manet is a REST API server which allows capturing screenshots of websites using various parameters.

The Node.js server can use SlimerJS or PhantomJS as headless browser engines.

I have build similar with CasperJS, but this is far better for those that want a simple straight solution.

Screen Scraping with Goutte

We all have been in situations were we need content or information from a connected website, but have no access to a REST Api or any other backend feed.

In these cases screen scraping is the only option to get needed information to finalize an integration. You can do that directly in CURL, but that can be tedious. Far easier to use a nicely packaged solution that combines a component that simulates web browser behavior and a component that eases DOM navigation for HTML and XML documents. Meet Goutte!

STEP 0

Install via composer.

composer require fabpot/goutte

1	composer require fabpot/goutte

STEP 1

$client = new Client();
$crawler = $client->request('GET', 'https://www.page/login.php');

// select the form and fill in some values
$form = $crawler->selectButton('Login')->form();
$form['f_loginname'] = 'HelloMe';
$form['f_loginpass'] = 'securepass';

// submit that form
$crawler = $client->submit($form);

// go to next page    
$crawler = $client->request('GET', 'https://www.page.de/overview.php');

$client = new Client();

$crawler = $client->request('GET', 'https://www.page/login.php');

// select the form and fill in some values

$form = $crawler->selectButton('Login')->form();

$form['f_loginname'] = 'HelloMe';

$form['f_loginpass'] = 'securepass';

// submit that form

$crawler = $client->submit($form);

// go to next page

$crawler = $client->request('GET', 'https://www.page.de/overview.php');

STEP 2

Get the data you need.

// loop over html and filter out what you need

$crawler->filter('table.clients tr')->each(function ($node) {

  $node->filter('td')->each(function ($sub_node) {
    echo $sub_node->html();
  }
}
