After i saw this trick into WpRecipes. You can add article numbers (ex. Article #1, Article #2) next to your posts. Let’s Begin…

Here is the code;

Add this code into your theme’s functions.php;

function updateNumbers() {
/* numbering the published posts: preparation: create an array with the ID in sequence of publication date, /
/ save the number in custom field 'incr_number' of post with ID  /
/ to show in post (within the loop) use <?php echo get_post_meta($post->ID,'incr_number',true); ?>
/ alchymyth 2010 */
global $wpdb;
$querystr = "SELECT $wpdb->posts.* FROM $wpdb->posts WHERE $wpdb->posts.post_status = 'publish' AND $wpdb->posts.post_type = 'post' ";
$pageposts = $wpdb->get_results($querystr, OBJECT);
$counts = 0 ;
if ($pageposts):
foreach ($pageposts as $post):
setup_postdata($post);
$counts++;
add_post_meta($post->ID, 'incr_number', $counts, true);
update_post_meta($post->ID, 'incr_number', $counts);
endforeach;
endif;
}

add_action ( 'publish_post', 'updateNumbers' );
add_action ( 'deleted_post', 'updateNumbers' );
add_action ( 'edit_post', 'updateNumbers' );

After this you can use this short code when you call your article names.

<?php echo get_post_meta($post->ID,'incr_number',true); ?>

That’s All. Have a nice day!

We can use WordPress as a CMS and we can change default loop area displaying for anywhere. We have to make a shortcode for this. Let’s Begin…

Here is the code;

Add this code to your theme’s functions.php and use shortcode in your teheme.

function myLoop($atts, $content = null) {
	extract(shortcode_atts(array(
		"pagination" => 'true',
		"query" => '',
		"category" => '',
	), $atts));
	global $wp_query,$paged,$post;
	$temp = $wp_query;
	$wp_query= null;
	$wp_query = new WP_Query();
	if($pagination == 'true'){
		$query .= '&paged='.$paged;
	}
	if(!empty($category)){
		$query .= '&category_name='.$category;
	}
	if(!empty($query)){
		$query .= $query;
	}
	$wp_query->query($query);
	ob_start();
	?>
	<h2><?php echo $category; ?></h2>
	<ul class="loop">
	<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
		<li><a href="<?php the_permalink() ?>" rel="bookmark"><?php echo $thumbnail_image; the_title(); ?></a></li>
	<?php endwhile; ?>
	</ul>
	<?php if(pagination == 'true'){ ?>
	<div class="navigation">
	  <div class="alignleft"><?php previous_posts_link('« Previous') ?></div>
	  <div class="alignright"><?php next_posts_link('More »') ?></div>
	</div>
	<?php } ?>
	<?php $wp_query = null; $wp_query = $temp;
	$content = ob_get_contents();
	ob_end_clean();
	return $content;
}
add_shortcode("loop", "myLoop");

ShortCode;

[loop category="news" query="" pagination="false"]

That’s All. Have a nice day!

This is not delete your posts, only turns to draft. When you change Loop area you will able to add an expration date with custom fileds. This is very simple function/recipe.Firstly you have to change your Loop area. You have to change your theme files for this. Every Loop area must change.

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!
