Since Twitter became popular, many bloggers like to display recent twitter tweets on their website or blog. To display most recent twitter tweets, simply copy and paste the following code to your sidebar.php file.

<?php
// Your twitter username.
$username = "TwitterUsername";
// Prefix - some text you want displayed before your latest tweet.
// (HTML is OK, but be sure to escape quotes with backslashes: for example href=\"link.html\")
$prefix = "";
// Suffix - some text you want display after your latest tweet. (Same rules as the prefix.)
$suffix = "";
$feed = "http://search.twitter.com/search.atom?q=from:" . $username . "&rpp=1";
function parse_feed($feed) {
$stepOne = explode("<content type=\"html\">", $feed);
$stepTwo = explode("</content>", $stepOne[1]);
$tweet = $stepTwo[0];
$tweet = str_replace(”&lt;”, “<”, $tweet);
$tweet = str_replace(”&gt;”, “>”, $tweet);
return $tweet;
}
$twitterFeed = file_get_contents($feed);
echo stripslashes($prefix) . parse_feed($twitterFeed) . stripslashes($suffix);
?>

Thanks the awesome code from WP Hacks.

Who don’t like to have comments on your blog? If your blog has many comments, it can be say that your blogs is popular, at least people like to interact with you to ask question and share information with you. If you really proud with your total number of comments on your blog, and want to show off to visitors.

To display the total number of comments on your blog, simple add the following code to your wordpress files.

<?php
$numcomms = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_approved = '1'");
if (0 < $numcomms) $numcomms = number_format($numcomms);
echo "There's ".$numcomms." total comments on my blog";
?>

Special thanks to PHP Magic Book for this awesome code.

Normally I will use page templates to display the archives which will list all posts on my blog, anyway you can use page templates to get specialized results apart from the basic static page template.

What you need to do is to add the following code to the first line of your php files, you can change the template name as you wish.

<?php
/*
Template Name: Archives
*/
?>

So now, you have to create a page template named Archives. Then, create a new page, find Template drop down box (refer picture) and choose Archives, this is a page template named Archives that you have created just now.

Many people will use Twitter counter badge from TwitterCounter.com to show twitter count in their website or blog, but twitter counter badges from TwitterCounter.com didn’t come with color personalization, sometimes it can’t match the color of the theme, so I don’t like to use it.

If you want to display Twitter count in plain text, you can follow the below steps.

1. Add the following code to functions.php.

function string_getInsertedString($long_string,$short_string,$is_html=false){
  if($short_string>=strlen($long_string))return false;
  $insertion_length=strlen($long_string)-strlen($short_string);
  for($i=0;$i<strlen($short_string);++$i){
    if($long_string[$i]!=$short_string[$i])break;
  }
  $inserted_string=substr($long_string,$i,$insertion_length);
  if($is_html && $inserted_string[$insertion_length-1]=='<'){
    $inserted_string='<'.substr($inserted_string,0,$insertion_length-1);
  }
  return $inserted_string;
}

function DOMElement_getOuterHTML($document,$element){
  $html=$document->saveHTML();
  $element->parentNode->removeChild($element);
  $html2=$document->saveHTML();
  return string_getInsertedString($html,$html2,true);
}

function getFollowers($username){
  $x = file_get_contents("http://twitter.com/".$username);
  $doc = new DomDocument;
  @$doc->loadHTML($x);
  $ele = $doc->getElementById('follower_count');
  $innerHTML=preg_replace('/^<[^>]*>(.*)<[^>]*>$/',"\\1",DOMElement_getOuterHTML($doc,$ele));
  return $innerHTML;
}

2. Copy and paste the following short code to anywhere on your theme files, remember replace your twitter username.

<?php echo getFollowers("yourtwitterusername")." followers"; ?>

Personally, I prefer to display my blog categories without in drop down box, but if you really have many categories on your blog, perhaps you can display categories in drop-down box so that your blog will looks more neat.

Below is the simple code to display categories:-

<h2>Categories</h2>
<ul>
<?php wp_list_cats('sort_column=name'); ?>
</ul>

To display categories in drop-down box, use the following code.

<form action="<?php bloginfo('url'); ?>/" method="get">
<?php
$select = wp_dropdown_categories('show_option_none=Select category&show_count=1&orderby=name&echo=0');
$select = preg_replace("#<select([^>]*)>#", "<select$1 onchange='return this.form.submit()'>", $select); echo $select; ?>
<noscript><input type="submit" value="View" /></noscript>
</form>

There are 2 ways to exclude certain categories from your blog, one is use wordpress plugin named Advanced Category Excluder. This plugin was born because there was a no other real alternative to enable content sparationd and some CMS like functionalities in WordPress. The main goal was, to enhance WordPress’s functionalities, to hide some unwanted categories, from defined parts of the blog.

The alternative way is without plugin, you can add the below code inside the loop then it will work.

<?php
if ( have_posts() ) : query_posts($query_string .'&cat=-1,-2'); while ( have_posts() ) : the_post();
?>
