Add a class to the first and last items of a WordPress menu

If you’re using the WordPress dynamic menus, you can use the following code to add first-menu-item and last-menu-item to the appropriate menu items.

Add the following to your theme’s functions.php:

function add_first_and_last($output) {
    $output = preg_replace('/class="menu-item/', 'class="first-menu-item menu-item', $output, 1);
    $output = substr_replace($output, 'class="last-menu-item menu-item', strripos($output, 'class="menu-item'), strlen('class="menu-item'));
    return $output;
}
add_filter('wp_nav_menu', 'add_first_and_last');

Bitbucket

github has definitely won the majority mindshare when it comes to open source git repository hosting. If you need private repositories it can get expensive. Bitbucket is a much better option. It isn’t as social as github, but offers most of the same features for free/cheap.

Writebox

Writebox is a simple editor for editing and creating text files in your Dropbox† account. No install, it runs in your web browser. (If that’s too easy for you, maybe vi in the Cloud is more your thing? vi in your browser with Dropbox integration.)

Validating Canadian Postal Codes with the JQuery Validation Plugin

If you’re using the JQuery Validation Plugin, you can use the following code snippet to validate a Canadian postal code:

jQuery.validator.addMethod("cdnPostal", function(postal, element) {
    return this.optional(element) || 
    postal.match(/[a-zA-Z][0-9][a-zA-Z](-| |)[0-9][a-zA-Z][0-9]/);
}, "Please specify a valid postal code.");

Then use the following rule:

$("#form").validate({
    rules: {
        postal_code: {
            required: true,
            cdnPostal: true
        }
    }
});
