Sass Compiler for WordPress

It uses the scssphp Compiler.

Compiler Page

Installation

  1. Download the latest release
  2. Unzip it into your wp-content/plugins directory
  3. Activate the plugin in WordPress

Compiler

This first page allows you to write and compile Sass. The resulting stylesheet is automatically enqueued.

Variables

This second page lists all registered variables, and allows you to edit their values upon compiling.

Variables Page after configuration

PHP Configuration

add_filter( 'sass_configuration', 'my_sass_config' );
function my_sass_config( $defaults ) {
  return array(
    'variables' => array( 'sass/_variables.scss' ),
    'imports'   => array( 'sass/bootstrap.scss', 'sass/_theme.scss' )
  );
}

Configuration of the plugin is optional, but you should at least register your variables if you are using a CSS framework.

Paths to Sass files are relative to the theme directory.

Use the filter 'sass_configuration' to return your configurations array.

  • variables(array)
    In order to list and edit your Sass variables on the plugin dedicated page, it is necessary to register their “definition” file(s). It is assumed that those files’ only role is to declare variables and their values.
  • imports(array)
    It will prepend the code to compile with an @import directive for each listed file. Useful to compile dependencies, and to “hide” them from the Compiler page. It is necessary to hit the “Compile” button once for these imports to be compiled.
  • cache(string)
    Allows you to define the path to your cache directory. This directory has to be writable (0755). The default cache directory path is wp-content/cache.
  • search(boolean)
    Wether or not to display the “Search Variables” filter box. It can come handy if you have a lot of variables. Default is true.

Once registered, you can access any variables with the function sass_get( 'my-variable' );, or override its value (upon what has been set on the Variables page) with sass_set( 'my-variable', 'my-value' ).
It is also possible to use @import directives, as well as any Sass language features, straight from the Compiler page.

Enqueuing external Sass

Out of the main stylesheet, simply use the WordPress wp_enqueue_style function to enqueue separated Sass files.

add_action( 'wp_enqueue_scripts', 'my_other_sass_enqueue' );
function my_other_sass_enqueue() {
  wp_enqueue_style( 'my-other-handle', get_template_directory_uri() . '/my-other-file.scss', array( 'wm-sass' ) );
}

It will be compared to the cached version, compiled if changes occurred, and the resulting stylesheet will be enqueued.
Don’t forget to set the main Sass stylesheet handle 'wm-sass' as a dependency (… if it is one).

LESS Compiler for WordPress

It uses the Less.php Compiler.

Installation

  1. Download the latest release
  2. Unzip it into your wp-content/plugins directory
  3. Activate the plugin in WordPress

Compiler

This first page allows you to write and compile LESS. The resulting stylesheet is automatically enqueued.

PHP Configuration

add_filter( 'less_configuration', 'my_less_config' );
function my_less_config( $config ) {
  $my_variables = array( 'less/variables.less' );
  $my_imports = array(
    'less/bootstrap.less',
    'less/theme.less'
  );
  return array_merge_recursive( $config, array(
    'variables' => $my_variables,
    'imports'   => $my_imports
  ) );
}

Configuration of the plugin is optional, but you should at least register your variables if you are using a CSS framework.

Paths to LESS files are relative to the theme directory.

Use the filter 'less_configuration' to return your configurations array.

  • variables(array)
    In order to list and edit your LESS variables on the plugin dedicated page, it is necessary to register their “definition” file(s). It is assumed that those files’ only role is to declare variables and their values.

WordPress Settings Framework for Options Pages

Settings are really useful to provide an easy configuration of themes and plugins to our users within their administration panel. But the creation of options pages often ends up in a messy and repetitive use of the great WordPress Settings API.

The option page generated with our really basic example.

Considering generic form fields, I wrote a class to clean and simplify the process. It’s something light that shall be used on the admin side.
https://github.com/WebMaestroFr/wm-settings

Example

// Define the page
$my_page = create_settings_page(
  'my_page_id',
  __( 'My Page' ),
  array(
    'title' => __( 'My Menu' )
  ),
  array(
    'my_setting_id' => array(
      'title'       => __( 'My Setting' ),
      'description' => __( 'This is my section description.' ),
      'fields'      => array(
        'my_option_name' => array(
          'label'        => __( 'My Option' ),
          'description'  => __( 'This is my field description.' )
        )
      )
    )
  )
);
// Access the values
$my_value = get_setting( 'my_setting_id', 'my_option_name' );

Installation

  1. Download the last release
  2. Unzip it into your theme or plugin
  3. require_once( 'path/to/wm-settings/wm-settings.php' );

Formatted and multiple fields, sections displayed as tabs

Apply settings anywhere, but in order to sanitise the data properly and to run the eventual callbacks, do it before ‘admin_init‘ is hooked.

$my_sub_page->apply_settings( array(
  'my_advanced_section' => array(
    'title'  => __( 'Advanced' ),
    'fields' => array(
      'my_media'  => array(
        'type'  => 'media',
        'label' => __( 'Media Example' )
      ),
      'my_color'  => array(
        'type'  => 'color',
        'label' => __( 'Color Example' )
      ),
      'my_action' => array(
        'type'        => 'action',
        'label'       => __( 'Action Example' ),
        'description' => __( 'Will call the PHP function "do_my_action" with AJAX.'),
        'action'      => 'do_my_action'
      )
    )
  ),
  'my_custom_section'   => array(
    'title'  => __( 'Custom' ),
    'fields' => array(
      'my_custom'   => array(
        'label'       => false,
        'description' => __( 'Will be sanitized through the PHP function "do_my_sanitation".'),
        'default'     => __( 'DEFAULT' ),
        'attributes'  => array(
          'style'   => 'font-family: "Comic Sans MS";',
          'pattern' => '[A-Z]*'
        ),
        'sanitize'    => 'do_my_sanitation'
      )
    )
  )
) );
function do_my_action() {
  // If error
  wp_send_json_error( __( 'Error !' ) );
  // If success
  wp_send_json_success( __( 'Success !' ) );
  // If the page needs to reload
  wp_send_json_success( array(
    'reload'  => true,
    'message' => __( 'This message is only displayed if "reload" => false.' )
  ) );
}
function do_my_sanitation( $input, $name ) {
  return sanitize_text_field( strtoupper( $input ) );
}
Advanced and Custom Fields

Get the values

Every setting is recorded as an array of options values. An easier way to get the data back, from anywhere in the code, is to use the function get_setting( $setting_id, $option_name );.

$my_attachment_id = get_setting( 'my_advanced_section', 'my_media' );
// ... is the same than :
$my_setting = get_option( 'my_advanced_section' );
$my_attachment_id = $my_setting['my_media'];

Callback after settings are updated

The class hooks actions tagged ‘(page_id)_settings_updated‘ when settings are updated.

add_action( 'my_top_level_page_settings_updated', 'do_my_page_callback' );
function do_my_page_callback() {
  // All settings of my_top_level_page have been updated.
}

You can also use the ‘update_option_(setting_id)WordPress action that will apply on every section update.

add_action( 'update_option_custom_fields_section', 'do_my_section_callback' );
function do_my_section_callback() {
  $my_custom_options = get_setting( 'my_custom_section' );
  // All options of custom_fields_section have been updated.
}

Custom notices

You can display custom notices on the options pages.

$my_page->add_notice( __( 'My info message.') );
$my_page->add_notice( __( 'My updated message.'), 'updated' );
$my_page->add_notice( __( 'My warning message.'), 'warning' );
$my_page->add_notice( __( 'My error message.'), 'error' );

Allowed types are info (default), updated, warning and error.

Custom notices

I’ve been working on and using this with fun. Feel free to contact me for questions, feedback or suggestions. And you can find all of it, fork and contribute on GitHub. Peace out.

A different Domain for each Language with qTranslate

Hey folks,

I like to use qTranslate for my multilingual websites. Today I had to set up a different language for each domain pointing on my WordPress installation. Here’s what was the simplest solution.

Multidomain qTranslate Settings

First, in your administration panel, in Settings > Languages, in Advanced Settings > URL Modification Mode, make sure you Use Pre-Path Mode.

Then, in your .htaccess (which shall be around your root directory), above the Rewrite Rules, redirect each one of those pre-paths to the wanted domain.

RedirectMatch 301 /fr/(.*) http://www.francais.fr/$1
RedirectMatch 301 /en/(.*) http://www.english.co.uk/$1

Too easy. Now in your theme’s functions.php file, configure qTranslate’s language settings according to the current domain. Let’s reset WordPress URLs as well, so it always link to the current domain.

define( 'WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] );
define( 'WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] );
$current_domain_lang = array_search( str_replace( 'www.', '', $_SERVER['HTTP_HOST'] ), array(
'fr' => 'francais.fr',
'en' => 'english.co.uk'
) );
$q_config['language'] = $current_domain_lang;
$q_config['default_language'] = $current_domain_lang;

Should work like a charm… tell me if you notice an issue though.

Image Parallax Plugin for WordPress

Upload the layers of your image, and create a parallax effect !

It works great on smart devices too !

The first step is to create with your favorite picture editing software (Photoshop, GIMP…) an independent image for each ground composing your image. All these layers shall be the same size, and should be in .png format as they are meant to include transparency areas.

Then, on your post editing page in WordPress, click the Insert Media button, and (the same way you would create a gallery) upload your layers under the Create Parallax item. Reorganise the layers if needed, from the background to the front.
You can finally configure the animation (calibrate, invert, limit, scalar, friction), and publish !

Example WordPress Parallax

This plugin uses parallax.js by Matthew Wagerfield.

Travel Routes WordPress Plugin

Easily add geographical tags on a map when you write a post, and it will automatically create new countries and localities terms. You can also order those locations randomly or by date to define your routes.

Use the map as a widget, and pick your own colors to customize it.

It is a SVG map that react to users actions (mouse over posts and terms links, click on route line…).

Enjoy folks.
