You should always encourage your clients to upgrade to the latest version, so you don’t have this problem. But if you are working with a client that does not want to upgrade, then it is essential that you remove your WordPress version number from your WordPress header, RSS feeds, and all other locations. To do this, add the following code:
function wpbeginner_remove_version()
return ”;
add_filter(‘the_generator’, ‘wpbeginner_remove_version’);
When creating themes for a client, you can use this as one of the perks to the theme. All you have to do is paste the following code below:
//hook the administrative header output
add_action(‘admin_head’, ‘my_custom_logo’);
function my_custom_logo()
echo ‘
<style type=”text/css”>
#header-logo background-image: url(‘.get_bloginfo(‘template_directory’).’/images/custom-logo.gif) !important;
</style>
‘;
You can change the footer of your Free or Custom WordPress themes by adding the necessary links. Simply paste the following code:
function remove_footer_admin () WordPress Tutorials: <a href=”http://www.wpbeginner.com” target=”_blank”>WPBeginner</a></p>’;
add_filter(‘admin_footer_text’, ‘remove_footer_admin’);
Often you will come across sites with outdated copyright dates. Some sites show the current year as their copyright date. Both of these are annoying, and it shows that the site designer was lazy. In order to give your users a little background info about your site, you should display the copyright date as such: © 2006 – 2010. We can do this by simply pasting the following code:
function comicpress_copyright()
global $wpdb;
$copyright_dates = $wpdb->get_results(”
SELECT
YEAR(min(post_date_gmt)) AS firstdate,
YEAR(max(post_date_gmt)) AS lastdate
FROM
$wpdb->posts
WHERE
post_status = ‘publish’
“);
$output = ”;
if($copyright_dates)
$copyright = “© ” . $copyright_dates[0]->firstdate;
if($copyright_dates[0]->firstdate != $copyright_dates[0]->lastdate)
$copyright .= ‘-’ . $copyright_dates[0]->lastdate;
$output = $copyright;
return $output;
Once you add this function, then open your footer.php file and add the following code wherever you like to display the dynamic copyright date:
<?php echo comicpress_copyright(); ?>
To do this, you must enable the post thumbnails inside your functions.php file. Paste the code below:
add_theme_support( ‘post-thumbnails’ );
Then simply place the following code inside your loop where you want to display the thumbnail:
<?php the_post_thumbnail(); ?>

If you want to create a more versatile author page, then you would need to add additional fields to the author profile. The code below will show you how to add additional twitter and facebook fields, but you can use it to add any other field that you like.
function my_new_contactmethods( $contactmethods )
// Add Twitter
$contactmethods['twitter'] = ‘Twitter’;
//add Facebook
$contactmethods['facebook'] = ‘Facebook’;
return $contactmethods;
add_filter(‘user_contactmethods’,'my_new_contactmethods’,10,1);
You can then call the fields in your author.php template by adding the following code:
<?php echo $curauth->twitter; ?>
When using WordPress as a CMS, sometimes the search feature becomes unnecessary. You can remove the search bar from the design, but the functionality still remains. You can add the following function and disable the search function:
function fb_filter_query( $query, $error = true )
if ( is_search() )
$query->is_search = false;
$query->query_vars[s] = false;
$query->query[s] = false;
// to error
if ( $error == true )
$query->is_404 = true;
add_action( ‘parse_query’, ‘fb_filter_query’ );
add_filter( ‘get_search_form’, create_function( ‘$a’, “return null;” ) );
Adsense is one of the most popular ad elements used by bloggers. Theme designers can place the adsense box in one spot which limits the users. If you want to give your client the ability to add the adsense anywhere, then you can create a shortcode for the adsense using this function:
function showads()
return ‘<div id=”adsense”><script type=”text/javascript”><!–
google_ad_client = “pub-XXXXXXXXXXXXXX”;
google_ad_slot = “4668915978″;
google_ad_width = 468;
google_ad_height = 60;
//–>
</script>
<script type=”text/javascript”
src=”http://pagead2.googlesyndication.com/pagead/show_ads.js”>
</script></div>’;
add_shortcode(‘adsense’, ‘showads’);
By default the excerpt length is capped at 55 words. Many theme designers like to have the flexibility that is why WordPress lets you customize the excerpt length with this function:
function new_excerpt_length($length)
return 100;
add_filter(‘excerpt_length’, ‘new_excerpt_length’);
// custom excerpt ellipses for 2.9
function custom_excerpt_more($more)
return ‘…’;
add_filter(‘excerpt_more’, ‘custom_excerpt_more’);
/* custom excerpt ellipses for 2.8-
function custom_excerpt_more($excerpt)
return str_replace(‘[...]‘, ‘…’, $excerpt);
add_filter(‘wp_trim_excerpt’, ‘custom_excerpt_more’);
*/
There are widgets that display Twitter followers count, but those are limited and ugly. You can use this function to customize the way your twitter followers count look on your blog. Simply paste the code below:
function rarst_twitter_user( $username, $field, $display = false )
$interval = 3600;
$cache = get_option(‘rarst_twitter_user’);
$url = ‘http://api.twitter.com/1/users/show.json?screen_name=’.urlencode($username);
if ( false == $cache )
$cache = array();
// if first time request add placeholder and force update
if ( !isset( $cache[$username][$field] ) )
$cache[$username][$field] = NULL;
$cache[$username]['lastcheck'] = 0;
// if outdated
if( $cache[$username]['lastcheck'] < (time()-$interval) )
// holds decoded JSON data in memory
static $memorycache;
if ( isset($memorycache[$username]) )
$data = $memorycache[$username];
else
$result = wp_remote_retrieve_body(wp_remote_request($url));
$data = json_decode( $result );
if ( is_object($data) )
$memorycache[$username] = $data;
if ( is_object($data) )
// update all fields, known to be requested
foreach ($cache[$username] as $key => $value)
if( isset($data->$key) )
$cache[$username][$key] = $data->$key;
$cache[$username]['lastcheck'] = time();
else
$cache[$username]['lastcheck'] = time()+60;
update_option( ‘rarst_twitter_user’, $cache );
if ( false != $display )
echo $cache[$username][$field];
return $cache[$username][$field];
Then place the following code where you want to display the count in your theme file:
echo rarst_twitter_user(‘wpbeginner’, ‘name’).’ has ‘.
rarst_twitter_user(‘wpbeginner’, ‘followers_count’).’ followers after ‘.
rarst_twitter_user(‘wpbeginner’, ‘statuses_count’).’ updates.’;
