    Sort by predefined order:

    $predefinedOrder = [1, 5, 2, 6];

usort($arrayOfObjects, function ($a, $b) use ($predefinedOrder) {

    $flipped = array_flip($predefinedOrder);

  • Add column to table in Laravel

    Add column to table in Laravel

    Create migration in console:

    php artisan make:migration add_mycolumn_to_mytable
    Bash

    Use Schema::table() to access existing table (instead of Schema::create() for creating new tables)

    public function up()
{
    Schema::table('mytable', function($table) {
        $table->text('mycolumn');
    });
}
public function down()
{
    Schema::table('mytable', function($table) {
        $table->dropColumn('mycolumn');
    });
}
    PHP

    Then run migrations:

    php artisan migrate
    Bash

  • (WordPress) Generate post title from custom field

    I had a custom post type that only used custom fields, so I needed to generate a post title from there.
    Here’s one way. You can if course chain as many if else as you want to check other types.

    functions.php
    [php]
    function custom_post_type_title($post_id)
    {
    global $wpdb;
    if (get_post_type($post_id) == ‘staff’) {
    $name = get_post_custom_values(‘name’);
    $title = $name[0];
    $where = array(‘ID’ => $post_id);
    $wpdb->update($wpdb->posts, array(‘post_title’ => $title), $where);
    }
    }

    add_action(‘save_post’, ‘custom_post_type_title’);

    [/php]

  • (JS) Newline to br

    Replaces newline characters with <br> tags in the same style as the php nl2br function

    // newline to br - php style
function nl2br(str, is_xhtml) {
    let breakTag = (is_xhtml || typeof is_xhtml === 'undefined') ? '<br />' : '<br>';
    return (str + '').replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1' + breakTag + '$2');

  • (Ruby) Ruby on Rails doodles

    Create new Ruby-on-Rails project. By default RoR comes with SQLite support, unless you state otherwise (-d mysql).
    [ruby]
    // Create project. With mysql support
    rails new my_project -d mysql
    [/ruby]

  • (JS) Super simple slider/carousel/slideshow

    Here’s how you can make a super simple slideshow that changes slides on a timer interval. You could easily edit it so any other event, like a mouse click, will trigger the slide() function.

    You can see it in action HERE

    HTML

    [html]
    <div class="slider">

    <div class="slide red">
    <p>THIS IS SLIDE 1</p>
    </div>

    <div class="slide blue">
    <p>THIS IS SLIDE 2</p>
    </div>

    <div class="slide green">
    <p>THIS IS SLIDE 3</p>
    </div>

    </div>
    [/html]

    CSS

    [css]
    .slider {
    width: 500px;
    height: 300px;
    margin: 0 auto;

    /* DON’T CHANGE THESE */
    position: relative;
    overflow: hidden;
    }

    .slide {
    /* DON’T CHANGE THESE */
    position: absolute;
    width: 100%;
    height: 100%;
    }

    /** ONLY FOR STYLING THE EXAMPLE SLIDES */
    .slide p {
    color: #FFF;
    text-align: center;
    }

    .red {
    background: red;
    }

    .blue {
    background: blue;
    }

    .green {
    background: green;
    }
    [/css]

    jQuery

    [js]
    <script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
    <script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
    <script>
    // Configurable values
    slider = $(‘.slider’); // Slider element
    slideDuration = 3000; // Duration of each slide in milliseconds
    slideSpeed = 1000; // Speed of slide animation in milliseconds (must be equal of less than slideDuration)

    width = slider.width();
    slider.children().hide().css({left: width});
    slider.children(‘:first’).show().css({left: 0});

    // Slide in from the left
    $.fn.slideIn = function () {
    $(this).show().animate({
    left: "-=" + width
    }, slideSpeed / 2);
    }

    // Slide out to the left
    $.fn.slideOut = function () {
    $(this).animate({
    left: "-=" + width
    }, slideSpeed / 2, function () {
    $(this).hide().css({left: width});
    });
    }

    // Main slide function
    function slide() {
    currentSlide = slider.find(‘div:visible:first’);
    nextSlide = (!slider.children(":last").is(":visible")) ? currentSlide.next() : slider.children(‘:first’);

    currentSlide.slideOut();
    nextSlide.slideIn();
    }

    // Timer function
    window.setInterval(function () {
    slide();
    }, slideDuration);
    </script>
    [/js]

    And of course you could make this dynamic by spitting out the slides from a database… for example like this:

    [php]
    <div class="slider">

    <?php foreach ($slides as $slide) { ?>

    <div class="slide">
    <p><?php $slide[‘content’] ?></p>
    </div>

    <?php } ?>

    </div>
    [/php]
