Archive widget: limit the number of months to 12

If you want to limit the number of months to only 12 for your Archive widget in your theme sidebar, use the widget_archives_args filter to add the archives limit.

Insert the following code into the functions.php file of your theme.

function my_limit_archives( $args ) {
    $args['limit'] = 12;
    return $args;
}
add_filter( 'widget_archives_args', 'my_limit_archives' );

And to limit the number of months in Archives widget drop-down, use the following drop-down filter by replacing the last line of the above code.

add_filter( 'widget_archives_dropdown_args', 'my_limit_archives' );

Limit the number of tags in your WordPress tag cloud widget

If your WordPress-powered site has a lot of tags (and growing), you will probably be struggling with a messy-looking list inside the tag cloud widget. But you would rather show a decent number of tags instead of removing the widget altogether, right?

Place the following code in your theme’s functions.php file which should resolve this issue.

//Register tag cloud filter callback
add_filter('widget_tag_cloud_args', 'tag_widget_limit');

//Limit number of tags inside widget
function tag_widget_limit($args){

 //Check if taxonomy option inside widget is set to tags
 if(isset($args['taxonomy']) && $args['taxonomy'] == 'post_tag'){
  $args['number'] = 10; //Limit number of tags
 }

 return $args;
}

Native pagination without plugins in WordPress

Any blogger who has been blogging on WordPress will be familiar with pagination plugins such as WP-PageNavi, which displays pagination like this:

But not everyone knows that WordPress has a built-in function (starting with version 2.1) which implements almost the same functionality. Thus the need for a plugin disappears. Continue reading →

WordPress: Add rel=”nofollow”

Add the following lines to your Theme’s template functions.php file or create it as a Plugin by filling the additional Standard Plugin Information:

function rel_nofollow( $content ) {
    return preg_replace_callback( '/<a[^>]+/', 'rel_nofollow_callback', $content );
}
add_filter( 'the_content', 'rel_nofollow', 99999 );

function rel_nofollow_callback( $matches ) {
    $link = $matches[0];

    $exclude = '('. home_url() .'|http://([^.]+.)?(wp.org|wp.com))';

    if ( preg_match( '#href=S('. $exclude .')#i', $link ) )
        return $link;

    if ( strpos( $link, 'rel=' ) === false ) {
        $link = preg_replace( '/(?<=<as)/', 'rel="nofollow" ', $link );
    } elseif ( preg_match( '#rel=S(?!nofollow)#i', $link ) ) {
        $link = preg_replace( '#(?<=rel=.)#', 'nofollow ', $link );
    }

    return $link;	
}

From the snippet above:

  1. Search for <a> tag
  2. Don’t do 3) and 4) if pattern matches home URL, wp.org and wp.com
  3. If rel attribute doesn’t exist, add rel=”nofollow”
  4. If rel attribute exist but no “nofollow” attribute value, add it

WordPress: Better previous and next post links

To be used on single post, the snippet below will not output unnecessary markup if there’s:

  1. only 1 published post.
  2. no post that is adjacent (previous or next) to current post.
<?php php if ( get_adjacent_post( false, '', false ) ||  get_adjacent_post( false, '', true ) ) : ?>
  <div class="navigation">
    <?php previous_post_link( '<div class="nav-previous">%link</div>', '<span class="meta-nav">&larr;</span> %title' ); ?>
    <?php next_post_link( '<div class="nav-next">%link</div>', '%title <span class="meta-nav">&rarr;</span>' ); ?>
  </div>
<?php endif; ?>
