WooCommerce provides great functionality, but loads a lot of resources even if not needed.

If a site loads longer than 5-7 seconds, potential customers already loose interest :)

UNLOAD ALL THAT IS NOT NEEDED

Add this to your functions.php:

Like always, make sure that nothing breaks. If things break or are required by certain pages add an exception for that!

Check WordPress Condional Tags.

SINGLE WEBSITE SETUP

Simple add this to your wp-config.php

MULTISITE SETUP

Use the MU-Domain-Mapping plugin for that.

We often have some posts that we would like to promote and keep at the first page of the blog. When you are using pagination, the sticky posts will be added to the standard posts, making the post count per page uneven.

If you want to keep your posts per page count consistent, there is a way to do that.

PREPARE PAGINATION

SWITCH QUERY FOR FIRST PAGE

Sometimes you want to add your own avatar for a user or build your own special predefined avatar selection :)

WHERE ARE THEY STORED

BuddyPress stores avatars in /wp-content/uploads/avatars/ – USERID – /

HOW ARE THEY STORED

BuddyPress hashes the original filename and stores full and thumbnail images in the above directory.

Now go ahead and build your own integration around that ;)

When using Fullpage.js, overflowing section / slide content will be made scrollable with Slimscroll. If you want to use addons that rely on the natural scroll event, these will fail with Slimscroll. One of the candidates breaking is Scrollreveal.js for example.

I decided to work around that, to allow animations to be triggered when elements become visible or invisible  to the viewport.

ADDITIONAL PLUGINS

You could code the viewport visibility check yourself or use the “visible” jquery plugin.

“This is a jQuery plugin which allows us to quickly check if an element is within the browsers visual viewport, regardless of the scroll position. If a user can see this element, the function will return true.” jquery-visible on Github

EXTENDING SLIMSCROLL WITHIN FULLPAGE.JS

The idea was to extend or hook into slimscroll without touching the fullpage.js codebase. Fullpage.js wraps overflowing content within a fp-scrollable container. Slimscroll itself provides events to track your position within the scrollable area in pixels or when top / bottom have been reached.

TRACK TOP / BOTTOM

TRACK POSITION

MAIN GOAL

  1. Hook into fullpage.js
  2. Track viewport & visible elements (jquery-visible)
  3. Track direction of scroll
  4. Get current position
  5. Assign classes to elements to trigger animations

MY SOLUTION

This is just a crude and simple starting point, but should give you the basic idea. This still needs some throttling, so that its not called on every scroll position.

HTML EXAMPLE

CSS EXAMPLE

Very basic idea to get some transitions working.

Hopefully Fullpage.js will be switching to iScroll natively in the future, as it provides far more options to handle scrollable areas. You can use iScroll now, but you have to disable the scrolling feature within Fullpage.js and call iScroll yourself. Not that difficult to do :)

There is also a WordPress Plugin that wraps Fullpage.js natively with a nice interface (WP_Fullpage) and my upcoming Visual Composer integration, which already uses iScroll :)

Sometimes you might like to store all language files in your own central location, so that translators have one easy place to access all language files.

Put the above into the functions.php and add textdomain handling for those you want to centralize.

Most current plugins should include the option to store language files to the global WordPress language folder, but that is sometimes just not enough  :) Its all about options ;)

Enjoy coding …

WPLMS is a Learning Management System for WordPress. Translation files in WPLMS are located in

  1. /wp-content/themes/wplms/languages/
  2. /wp-content/plugins/vibe-course-module/languages/
  3. /wp-content/plugins/vibe-customtypes/languages/
  4. /wp-content/plugins/vibe-shortcodes/languages/
  5. /wp-content/plugins/wplms-assignments/languages/
  6. /wp-content/plugins/wplms-dashboard/languages/
  7. /wp-content/plugins/wplms-events/languages/
  8. /wp-content/plugins/wplms-front-end/languages/

These language files will be overwritten with new files on every update, destroying any custom translation changes.

THE THEME

Move your theme into a child theme and translate your theme there (/wp-content/themes/your-child-theme/languages/).

Make sure that language files are loaded from your child theme. Add the following action to your functions.php and use “vibe” as the domain, not the actual theme name.

THE PLUGINS

Use the global language folder for the WPLMS plugin translations. The WPLMS plugin loader checks, if a global language file actually exists :)

  1. /wp-content/languages/plugins/vibe-de_DE.mo
  2. /wp-content/languages/plugins/vibe-customtypes-de_DE.mo
  3. /wp-content/languages/plugins/wplms-assignments-de_DE.mo
  4. /wp-content/languages/plugins/wplms-dashboard-de_DE.mo
  5. /wp-content/languages/plugins/wplms-events-de_DE.mo
  6. /wp-content/languages/plugins/wplms-front-end-de_DE.mo
  7. +++

POEDIT

I suggest using Poedit, as it allows you to do the translation on the Desktop. It also offers options to update your file with an updated WPLMS language file, allowing you to add new translation strings if needed :)

PREPARE

A. Create the structure for the update and download new PO files from WPLMS

  1. /wp-content/themes/wplms/languages/
  2. /wp-content/plugins/vibe-course-module/languages/
  3. /wp-content/plugins/vibe-customtypes/languages/
  4. /wp-content/plugins/vibe-shortcodes/languages/
  5. /wp-content/plugins/wplms-assignments/languages/
  6. /wp-content/plugins/wplms-dashboard/languages/
  7. /wp-content/plugins/wplms-events/languages/
  8. /wp-content/plugins/wplms-front-end/languages/

B. The target structure / your current language files

  1. /wp-content/themes/your-child-theme/languages/de_DE.mo /.po
  2. /wp-content/languages/plugins/vibe-de_DE.mo /.po
  3. /wp-content/languages/plugins/vibe-customtypes-de_DE.mo /.po
  4. /wp-content/languages/plugins/wplms-assignments-de_DE.mo /.po
  5. /wp-content/languages/plugins/wplms-dashboard-de_DE.mo /.po
  6. /wp-content/languages/plugins/wplms-events-de_DE.mo /.po
  7. /wp-content/languages/plugins/wplms-front-end-de_DE.mo /.po
  8. +++

C. Open your current .PO file from target structure

wplms_trans_1

D. Update with new and matching .PO file from A. (Catalog -> Update from POT file)

This will check for new or obsolete strings and update your language file.

wplms_trans_2

wplms_trans_ 20.13.19

E. New strings added

wplms_trans_4

F. Obsolete strings removed

wplms_trans_3

G. Save and upload updated .PO + .MO files from target structure to server.

Again, make sure to use the global language folder and the child theme languages folder !

Panic time after updates is over :)

Enjoy coding ….
