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// if outdated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.’;
