Here is the code;

1st step:  Get your post from SQL

We will use sql command for get random post. Here is the command;

SELECT guid FROM wp_posts WHERE post_type = 'post' AND post_status = 'publish' ORDER BY RAND() LIMIT 1

Explaining of this command;

guid: The URL of our post

wp_posts: The table of posts

post_type: This is the type of we get

post_status: Is this published? Yes

order by rand: Randomize of our request

Limit: We limited for 1 post.

2nd Step: Locate the php code where you want.

<?php
$randomPost = $wpdb->get_var("SELECT guid FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish' ORDER BY rand() LIMIT 1");
echo '<a href="'.$randomPost.'">Random Post</a>';
?>

You can add this code where you want.
That’s All. Have a nice day!

Here is the code;

function catch_that_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Varsayılan küçük resim
$first_img = "wp-content/themes/tema adı/images/default.png";
}
return $first_img;
}

This is the output;

catch_that_image()

This is the usage;

Usage with the img tag;

<img src="<?php echo catch_that_image() ?>" alt=""/>

Usage on site;

<span class="custom_image">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Read: <?php the_title_attribute(); ?>"><img src="<?php echo catch_that_image() ?>" alt=""/> </a>
</span>

And CSS;

.custom_image img{float:left; padding:3px; margin:7px 10px 15px 0; border: 2px solid #e6e6e6; height:90px; width:90px}

That’s All!

Here is The Code;

<?php
$original_post = $post;
$tags = wp_get_post_tags($post->ID);
if ($tags) {
  echo '<h2>Related Posts</h2>';
  $first_tag = $tags[0]->term_id;
  $args=array(
    'tag__in' => array($first_tag),
    'post__not_in' => array($post->ID),
    'showposts'=>4,
    'caller_get_posts'=>1
   );
  $my_query = new WP_Query($args);
  if( $my_query->have_posts() ) {
    echo "<ul>";
    while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <li><img src="<?php bloginfo('template_directory'); ?>/timthumb/timthumb.php?src=<?php echo get_post_meta($post->ID, "post-img", true); ?>&h=40&w=40&zc=1" alt="" /><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile;
    echo "</ul>";
  }
}
$post = $original_post;
wp_reset_query();
?>

Add this code after content. Look at Tim Thumb at here. Have a nice day!

Here is the code;

Firstly we call the extra .php file for this. You can apply this code where you want;

<?php if(is_home() !is_paged()): ?>
<?php // Featured posts go here.
include (TEMPLATEPATH . "/featured.php"); ?>
<?php endif;?>

That’s calling function and here is the page code;

Firstly create a featured.php and upload into wp-content/themes/your-theme/ .  Change category number with your featured content category number. Insert this code into file…

Code…

    <!-- start Featured -->
<?php query_posts("showposts=1&cat=6"); ?>
<?php while (have_posts()) : the_post(); ?>
<div id="featured">
<div id="featured2">
<div id="featurediv">
<div class="epic">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Continue reading <?php the_title(); ?>"><img src="<?php $values = get_post_custom_values("Thumbnail"); echo $values[0]; ?>" alt="Continue reading <?php the_title(); ?>" /></a>
</div>
<div class="etext">
<div class="ehead">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Continue reading <?php the_title(); ?>"><?php the_title(); ?></a></h2>
<div class="entryinfo"><?php edit_post_link('Edit', '', ' |'); ?> Posted by <strong><?php the_author(); ?></strong> on <?php the_time('d M Y'); ?> under <?php the_category(', ') ?> | <?php comments_popup_link('0 Comments', '1 Comment', '% Comments'); ?>
</div>
</div>
<div class="post">
<?php the_excerpt(); ?>
</div>
</div>
<div class="clearer"></div>
</div>
</div>
</div>
<?php endwhile; ?><!-- end Featured -->

That’s All!

You can disable auto save with this code. You can edit/create your functions.php. Be careful and make back-up.

function disableAutoSave(){
 wp_deregister_script('autosave');
}
add_action( 'wp_print_scripts', 'disableAutoSave' );

Have a nice day!

Here is the code;

<?php comments_rss_link('» Comments RSS Feed'); ?>

If you add this code to in the Loop of your theme’s single.php you have a RSS link on every post.

That’s All. Have A nice Day!

Here is the code;

<?php query_posts('showposts=10&post_status=future'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
 <h2><?php the_title(); ?></h2>
 <span><?php the_time('j. F Y'); ?></span></p>
 <?php endwhile;
 else: ?><p>No future events scheduled.</p>
 <?php endif; ?>

That’s All. Have a nice day!

Change your Loop area wtih this code.

<?php
if (have_posts()) :
     while (have_posts()) : the_post(); ?>
         $expirationtime = get_post_custom_values('expiration');
         if (is_array($expirationtime)) {
             $expirestring = implode($expirationtime);
         }

         $secondsbetween = strtotime($expirestring)-time();
         if ( $secondsbetween > 0 ) {
             // For example...
             the_title();
             the_excerpt();
         }
     endwhile;
endif;
?>

After apply this code you can add a custom filed, the name of custom filed is expration. The custom fileds value must be like mm/dd/yyyy 00:00:00.

That’s All! Have a nice day!
