Floating Labels for Bootstrap 3

As I’m working quite a lot with Bootstrap these days, I wrote a jQuery plugin to apply a “floating” effect on the framework’s horizontal forms labels.

Plugin

The jQuery plugin is very simple. Here is the full code.

(function ($) {
  'use strict';
  $.fn.bsPeekabooLabel = function () {
    var input = $(this),
      control = input.closest('[class*="col-"]'),
      label = control.siblings('.control-label'),
      show = false,
      place = function (d) {
        var m;
        if ($(control).css('float') === 'left') {
          m = '0 0 0 ' + label.outerWidth() + 'px';
          label.animate({ margin: show ? 0 : m, opacity: show ? 1 : 0 }, d);
          control.animate({ margin: m }, d);
        } else {
          label.animate({ margin: 0, opacity: 1 }, d);
          control.animate({ margin: show ? label.outerHeight() + 'px 0 0' : 0 }, d);
        }
      };
    label.css({ position: 'absolute' });
    place(0);
    input.keyup(function () {
      if (show === !input.val()) {
        show = !show;
        place(400);
      }
    });
    $(window).resize(function () { place(0); });
  };
}(jQuery));

How To Use

First, make sure your horizontal form respects Bootstrap’s HTML structure, and that your inputs have a placeholder attribute. Then, target each input you want to apply the effect to.

$('.form-control[placeholder]', '.form-horizontal').each(function () {
  $(this).bsPeekabooLabel();
});

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.

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' );
The option page generated with our really basic example.

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.

A jQuery Plugin to Fade In and Out with a Vertical Slide

JQuery’s .show() and .hide() effects are useful, but I’m not cool with their width resizing.
This plugin allows you to show and hide elements with a vertical slide and a fading effect.

You can use the .showDown(), .hideUp() and .verticalFade() functions the same way you would use jQuery’s .fadeIn(), .fadeOut() or .fadeToggle() effects.

$('#trigger-example').click(function () {
  $('#example').verticalFade({ duration: 'slow' });
});

https://gist.github.com/WebMaestroFr/9316374

Plugin

The jQuery plugin is very simple. Here is the full code.

(function ($) {
  var getUnqueuedOpts = function (opts) {
    return {
      queue: false,
      duration: opts.duration,
      easing: opts.easing
    };
  };
  $.fn.showDown = function (opts) {
    opts = opts || {};
    $(this).hide().slideDown(opts).animate({ opacity: 1 }, getUnqueuedOpts(opts));
  };
  $.fn.hideUp = function (opts) {
    opts = opts || {};
    $(this).show().slideUp(opts).animate({ opacity: 0 }, getUnqueuedOpts(opts));
  };
  $.fn.verticalFade = function (opts) {
    opts = opts || {};
    if ($(this).is(':visible')) {
      $(this).hideUp(opts);
    } else {
      $(this).showDown(opts);
    }
  };
}(jQuery));

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.

Omnifinder, a Time-Saving Search Engine

Hey guys, if you didn’t came across Omnifinder yet, give it a try.

It allows you to search straight on any defined or customised website, instead of having to reach its searching page. One landing page for them all, that’ll make you save some precious seconds !

It’s my friend Maxime‘s work (the guy that made Canvas Rider), and he made it efficient as usual.

Mes jolies cartes de visite

On appellerait bien ça du “personal branding”, sous mon statut d’indépendant.

J’ai donc eu le plaisir de réaliser, accompagné de l’agence de communication KlubGraphik, ces cartes de visites pour mon auto-entreprenariat !

Bon alors bien sûr il faut les voir en vrai, toutes vernies mat et découpées arrondies qu’elles sont. En tout cas, bravo à Pascal pour ce joli design.

C’est peut-être anodin pour beaucoup ces cartes, mais ça marque pour moi l’affirmation de cette fraîche situation dont je souhaite d’ores et déjà communiquer le professionalisme.

Au plaisir, donc, de vous en remettre une en main propre !
