The following is a snippet of code I used to display a widget with the ID video title after the widget (rather than before the widget).

<?php $sidebar_id = 'video';
$sidebars_widgets = wp_get_sidebars_widgets();
$widget_ids = $sidebars_widgets[$sidebar_id];
foreach( $widget_ids as $id ) {
   $wdgtvar = 'widget_'._get_widget_id_base( $id );
   $idvar = _get_widget_id_base( $id );
   $instance = get_option( $wdgtvar );
   $idbs = str_replace( $idvar.'-', '', $id );
} ?>

<section id="video">
   <div class="inner">
      <div class="container">
         <?php dynamic_sidebar( 'video' ); ?>
         <?php echo $instance[$idbs]['title']; ?>
      </div>
   </div>
</section>

A big thankyou to Evan Herman over at Code Parrots who helped me out with the following solution to an request that I submitted. He has developed a terrific timeline plugin for Wordpress, that is very flexible and looks super jazzy.

Here is a handy snippet that will allow you to create your own preformatted custom styles within the Wordpress text editor. The new styles are selected by a drop down field titled Formats. 

The following adds a bunch of usefull social media links to the wordpress user profiles - and also allows simple HTML within the user bio. Add this code to the theme functions.php file.

/*===================================================================================
 * Add Author Links
 * =================================================================================*/
function add_to_author_profile( $contactmethods ) {

    $contactmethods['rss_url'] = 'RSS URL';
    $contactmethods['google_profile'] = 'Google Profile URL';
    $contactmethods['twitter_profile'] = 'Twitter Profile URL';
    $contactmethods['facebook_profile'] = 'Facebook Profile URL';
    $contactmethods['instagram_profile'] = 'Instagram Profile URL';
    $contactmethods['linkedin_profile'] = 'Linkedin Profile URL';

    return $contactmethods;
}
add_filter( 'user_contactmethods', 'add_to_author_profile', 10, 1);
//disable WordPress sanitization to allow more than just $allowedtags from /wp-includes/kses.php
remove_filter('pre_user_description', 'wp_filter_kses');
//add sanitization for WordPress posts
add_filter( 'pre_user_description', 'wp_filter_post_kses');

Now dial it all up within the author.php file of your theme with the following code:

<div id="description" class="node"><?php the_author_meta('description'); ?></div>


<ul class="icons">
    <?php
    $site = get_the_author_meta( 'user_url' );
    if ( $site && $site != '' ) {
        echo '<li class="site"><a target="_blank" href="' . esc_url($site) . '">Website</a></li>';
    }


    $rss_url = get_the_author_meta( 'rss_url' );
    if ( $rss_url && $rss_url != '' ) {
        echo '<li class="rss"><a target="_blank" href="' . esc_url($rss_url) . '">RSS</a></li>';
    }

    $google_profile = get_the_author_meta( 'google_profile' );
    if ( $google_profile && $google_profile != '' ) {
        echo '<li class="google"><a target="_blank" href="' . esc_url($google_profile) . '" rel="author">Google+</a></li>';
    }

    $twitter_profile = get_the_author_meta( 'twitter_profile' );
    if ( $twitter_profile && $twitter_profile != '' ) {
        echo '<li class="twitter"><a target="_blank" href="' . esc_url($twitter_profile) . '">Twitter</a></li>';
    }

    $facebook_profile = get_the_author_meta( 'facebook_profile' );
    if ( $facebook_profile && $facebook_profile != '' ) {
        echo '<li class="facebook"><a target="_blank" href="' . esc_url($facebook_profile) . '">Facebook</a></li>';
    }

    $linkedin_profile = get_the_author_meta( 'linkedin_profile' );
    if ( $linkedin_profile && $linkedin_profile != '' ) {
        echo '<li class="linkedin"><a target="_blank" href="' . esc_url($linkedin_profile) . '">Linkedin</a></li>';
    }

    $instagram_profile = get_the_author_meta( 'instagram_profile' );
    if ( $instagram_profile && $instagram_profile != '' ) {
        echo '<li class="Instagram"><a target="_blank" href="' . esc_url($instagram_profile) . '">Instagram</a></li>';
    }
    ?>
</ul>

Here's a very handy snippet to create a PHP conditional if statement based on a specific K2 item ID:

<?php
$itemid    = JRequest::getInt('Itemid');

if( $itemid == 123 ) {
   echo 'do something';
} else {
   echo 'these are not the droids you are looking for';
}
?>

<?php
$itemid    = JRequest::getInt('Itemid');

if( $itemid == 123 ) {
   echo 'do something';
} else {
   echo 'these are not the droids you are looking for';
}
?>

The code above can be altered using the following hooks from the page URL:

$option = JRequest::getCmd('option');
$view  = JRequest::getCmd('view');
$layout = JRequest::getCmd('layout');
$page  = JRequest::getCmd('page');
$task  = JRequest::getCmd('task');
$id    = JRequest::getInt('id');

Here's a handy little snippet that determines if an entry is a post or page within a loop. I found this usefull for determining the entry type within search results, where I wanted to style the results differently depending on what type of result it was.

<?php
$pagetype = get_post_type( $post_id );

echo $pagetype;

if ($pagetype == "post") {
    // do something
 }
?>

The following creates a loop of custom post types. This example creates a testimomnials block. 

<?php $loop = new WP_Query( array( 'post_type' => 'testimonial',
        'posts_per_page' => 4 )
); ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

    <?php
    $clientname = (types_render_field( "client-name", array( 'raw' => true) ));
    $quote = (types_render_field( "quote", array( 'raw' => true) ));
    ?>

   <p><?php echo $quote; ?>&nbsp;<span><?php echo $clientname; ?></span></p>

<?php endwhile; wp_reset_query(); ?>

Put the following in the themes functions.php file:

function is_blog () {
    global  $post;
    $posttype = get_post_type($post );
    return ( ((is_archive()) || (is_author()) || (is_category()) || (is_home()) || (is_single()) || (is_tag())) && ( $posttype == 'post')  ) ? true : false ;
}

Test it using the following conditional within your theme:

<?php if (is_blog()) { echo 'You are on a blog page'; } else { echo 'no blog'; } ?>

Take a look in the themes comments.php file and you will see a line where the comments area is called in using:

<?php comment_form(); ?>

In some cases I found it was contained within a conditional like this:

if ( comments_open() ) comment_form();

You can replace it with the following code, injecting in any modifications to the fields as you need:

if ( comments_open() ) { ?>

    <?php $comment_args = array( 'title_reply'=>'Leave a reply',

        'fields' => apply_filters( 'comment_form_default_fields', array(

                'author' =>
                    '<div class="row">
                        <div class="large-4 columns comment-form-author">' .
                            '<input id="author" 
name="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) .
                    '" size="30"' . $aria_req . ' placeholder="Name*" />
                        </div>',

                'email' =>
                      '<div class="large-4 columns comment-form-email">' .
                            '<input id="email" name="email" type="text" 
value="' . esc_attr(  $commenter['comment_author_email'] ) .
                    '" size="30"' . $aria_req . ' placeholder="Email*" />
                      </div>',

                'url' =>
                    '<div 
class="large-4 columns comment-form-url">' .
                            '<input id="url" name="url" type="text" value="' . esc_attr( $commenter['comment_author_url'] ) .
                    '" size="30" 
placeholder="Website" />
                    </div>
                </div>', )
        ),

        'comment_field' => '<div>' .

            '<textarea id="comment" name="comment" cols="45" rows="8" aria-required="true" placeholder="Comment*" 
></textarea>' .

            '</div>',

        'comment_notes_after' => '',

    );

    comment_form($comment_args); ?>


<?php } ?>

This function tells WordPress to remove the default more which looks like this: […], and replace it with a link.

Open your functions.php file, and paste the following code inside the php tags:

// Changing excerpt more
function new_excerpt_more($more) {
    global $post;
    return '… <a href="'. get_permalink($post->ID) . '">' . 'Read More &raquo;' . '</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');
