What will you do if wordpress plugin broken your wordpress blog? I believe that most people have experienced this problem before, and how you overcome your problem? I remember when my wordpress blog was unable displayed properly after installed particular wordpress plugin, so I deleted all the wordpress files, wordpress themes, wordpress plugins, and then I upload all the files again. Anyway, it is work fine finally.

If you can’t display your wordpress blog after installed particular wordpress plugin, you can follow the below steps to solve this problem.

1. De-active the Plugin
Try to de-active the wordpress plugin that you have installed just now.

2. Rename the Plugin via FTP
If it is crash by admin area and caused you can’t de-active the plugins, then you can rename the plugins via FTP.

3. Delete the Plugin via FTP
If simply renaming the plugin was not enough, try to delete it completely.

4. De-activate all the plugins via PHPMyAdmin
Some plugins will alter tables in your WordPress database when you activate them. As a result your blog might keep crashing even after you delete the plugins via FTP.

If that is the case, you will need to log into cPanel, and open the PHPMyAdmin interface. Then select the WordPress database, and browse inside the “wp-options” table. Look for the “active_plugins” column, and edit it. Inside the “options_value” field you will find something like this:

a:31:{i:0;s:13:"AddMySite.php";i:1;s:19:"akismet/akismet.php";
i:2;s:23:"all_in_one_seo_pack.php";i:3;s:16:"authenticate.php";
i:4;s:28:"breadcrumb-navigation-xt.php";i:5;s:18:
"codeautoescape.php";i:6;s:37:

These lines represent the active plugins in your blog. Delete them all and save. This should automatically de-activate every plugin. Now check if your blog is live again, and if the admin area is working. They should be.

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);
?>

echo ('Your main description goes here');
} elseif(is_category()) {
echo category_description();
} elseif(is_tag()) {
echo '-tag archive page for this blog' . single_tag_title();
} elseif(is_month()) {
echo 'archive page for this blog' . the_time('F, Y');

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.

I don’t think you will need to add a print button to your posts on your blog, but in case you want to have it, you can just copy and paste the following code into single.php file. It’s looks simple, right? @_@

<a href="javascript:window.print()">Print this Article</a>

If you want to display Google Adsense After the first post, then you can refer to the following code and see how it works. Honestly, this is a wonderful code that I have been looking for so long.

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); $loopcounter++; ?>

// the loop stuffs

<?php if ($loopcounter <= 1) { include (TEMPLATEPATH . '/ad.php'); } ?>

<?php endwhile; ?>
<?php else : ?>
<?php endif; ?>

Thanks Web Designer Wall for this awesome code.

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"; ?>

Most wordpress themes combine comments with trackbacks, if you want to separate comments and trackbacks so that it will looks more organized, then you can follow the below step by step guide.

Step 1

<?php foreach ($comments as $comment) : ?>

Paste after

<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type == 'comment') { ?>

Step 2

Scroll down a bit and look for

<?php endforeach; /* end for each comment */ ?>

Paste before

<?php } else { $trackback = true; } /* End of is_comment statement */ ?>

Step 3

<h3>Trackbacks</h3>
<ol>
<?php foreach ($comments as $comment) : ?>
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type != 'comment') { ?>
<li><?php comment_author_link() ?></li>
