Require Additional Profile Fields at Registration

<?php

add_action( 'register_form', 'additional_profile_fields' );
function additional_profile_fields() { ?>
    <p>
        <label><?php _e('First Name') ?><br />
        <input type="text" name="first_name" id="first_name" class="input" size="25" tabindex="20" /></label>

    <p>
        <label><?php _e('Last Name') ?><br />
        <input type="text" name="last_name" id="last_name" class="input" size="25" tabindex="20" /></label>
    </p>
<?php }
 
add_action( 'register_post', 'add_register_field_validate_first_name', 10, 3 );
function add_register_field_validate_first_name( $sanitized_user_login, $user_email, $errors) {
    if (!isset($_POST[ 'first_name' ]) || empty($_POST[ 'first_name' ])) {

    }

Add Some Fancy to the Edit Page/Post Link

Inspired by this tweet.

Add a little bit of fancy to your edit link in the Admin Bar with this:

add_action( 'wp_before_admin_bar_render', 'adminbar_tweaks');

function adminbar_tweaks() {
    global $wp_admin_bar;

    if (isset( $wp_admin_bar->menu->edit['title'] ) ) {
        $title = $wp_admin_bar->menu->edit['title'];
        if ( substr( $title, 0, 5 ) == 'Edit ' ) {
            $hand = '<span style="font-size:20px;margin:-1px 3px 0 0;float:left;">✍</span>';
            $wp_admin_bar->menu->edit['title'] = $hand.$title;
        }
    }

}

Move Privacy Notice in 3.2

If you’ve already started poking around in WordPress 3.2, you may have noticed that the privacy notice that used to appear in the WordPress header has been moved to the Right Now box on the dashboard.

And if you’re like me, you probably wish it was back at the top. Fortunately, with just a few lines, we can do that:

add_action('in_admin_header', 'privacy_notice_in_header');
function privacy_notice_in_header() {
    if (1 != get_option('blog_public')) {
        $title = apply_filters('privacy_on_link_title', __('Your site is asking search engines not to index its content') );
        $content = apply_filters('privacy_on_link_text', __('Search Engines Blocked') );
        echo "<p class='alignleft' style='padding:9px 0 0;margin:0;'><a href='options-privacy.php' title='$title'>$content</a></p>";
    }
}

Redirect When Search Query Only Returns One Match

Be careful when using this, as users may not expect this functionality.

If there’s only one match for a particular search query, you can save users the hassle of clicking by simply redirecting them to the page/post.

add_action('template_redirect', 'single_result');
function single_result() {
	if (is_search()) {
		global $wp_query;
		if ( $wp_query->post_count == 1 && $wp_query->max_num_pages == 1 ) {
			wp_redirect( get_permalink( $wp_query->posts[0]->ID ) );
			exit;
		}
	}
}

Redirect When Search Query is an Exact Title Match

You probably shouldn’t use this if you have really generic page/post titles, but it can be a really handy feature.

Basically, if a user searches for something that happens to be an exact match to a page or post you have, it’ll redirect the user to the page, rather than displaying search results.

add_action('template_redirect', 'seach_query_is_title');
function seach_query_is_title() {
	if (is_search()) {
		global $wp_query;
		if ( get_page_by_title( get_search_query(), 'OBJECT', 'post' ) ) {
			wp_redirect( get_permalink( get_page_by_title (get_search_query() )->ID ) );
		}
		elseif ( get_page_by_title( get_search_query(), 'OBJECT', 'page' ) ) {
			wp_redirect( get_permalink( get_page_by_title( get_search_query() )->ID ) );
		}
	}
}
