I have seen in some forums and different websites, some doubts about how codeigniter is organized and how can it help you as a coder be more efficient. The first thing people should know is, codeigniter is a PHP framework, made with the software architecture known as MVC which stands for Model-View-Controller. This architecture seperates the logic from user interface allowing independant development, testing and better maintenance. Codeigniter allows you to have your code much organized, making you look better at what you already do. This framework is made to facilitate the way you do certain things in PHP, and allow you to reuse your code, using PHP Object Oriented programming paradigm. Codeigniter, on my opinion, seems to be very user friendly, so it’s to which I would recommend the use of it, for any upcoming web developer.

Well today is your lucky day, I ran across the need to do this on one of my recent free themes. Below is the code:

	// First lets get the custom field , we are assuming its called "thumb"
	$thumb = get_post_meta($post->ID, 'thumb', true);

	// Check if a post thumbnail is already set, if so don't do anything.
	if( has_post_thumbnail( $post->ID ) ) {

	} else {

		if ( ! empty($thumb) ) {

			// Download file to temp location
			$tmp = download_url( $thumb );

			// Set variables for storage
			// fix file filename for query strings
			preg_match('/[^\?]+\.(jpg|JPG|jpe|JPE|jpeg|JPEG|gif|GIF|png|PNG)/', $thumb, $matches);
			$file_array['name'] = basename($matches[0]);
			$file_array['tmp_name'] = $tmp;

			// If error storing temporarily, unlink
			if ( is_wp_error( $tmp ) ) {
				@unlink($file_array['tmp_name']);
				$file_array['tmp_name'] = '';
			}

			// do the validation and storage stuff
			$id = media_handle_sideload( $file_array, $post->ID, NULL );
			// If error storing permanently, unlink
			if ( is_wp_error($id) ) {
				@unlink($file_array['tmp_name']);
				return $id;
			}

			// Set the featured image
			set_post_thumbnail( $post->ID, $id );

		}

	}

echo '<ul id="Thumbnails">';

$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => $post->ID );
$attachments = get_posts($args);
if ($attachments) {
foreach ( $attachments as $attachment ) {

$image_attributes 	= wp_get_attachment_image_src( $attachment->ID ); // returns an array
$imgTitle	        = $attachment->post_title;
$imgCaption 		= $attachment->post_excerpt;
$imgDescription		= $attachment->post_content;

echo '<li><a href="' . $attachment->guid . '"><img '; 

if ( $attachment->post_name == $_GET['image'] ) { echo 'class="active"'; }

echo ' src="' . $attachment->guid . '" title="' . $imgCaption . '" alt="' . $imgTitle . ' - ' . $imgDescription . '"  /></a></li>' . "\n";

}
}

echo '</ul>' . "\n";
echo '<div style="clear: both;"></div>';

// Adds <span></span> around the first word of Widget titles
function arixWP_widget_title($title) {
$title = preg_replace('/(^[A-z0-9_]+)\s/i', '<span>$1</span> ', $title);
return $title;
}
add_filter('widget_title', 'arixWP_widget_title');

		function arixWP_title()
		{

			global $post;

			$title = '<h2 class="title"><a href="' . get_permalink() . '" title="' . get_the_title() . '" rel="bookmark">' . get_the_title() . '</a></h2>';
			$title = preg_replace('/<a([^>]+)>([A-z0-9_]+)\s/i', '<a$1><span>$2</span> ', $title);

			echo $title;

		}	

Usage

Where ever you would like the title to show up paste the following code:

<?php arixWP_title(); ?>

PHP’s historical lack of namespace support has long been a sore spot for developers residing both within and without the PHP community. Lacking the ability to efficiently organize project libraries, PHP developers have long made do with various contrived hacks, including notably using an autoloader in conjunction with code organized within a nested folder structure. Such an approach is used by the PHP Extension and Application Repository (PEAR), as well as by popular frameworks such as the Zend Framework.

I recently had to update a MySQL schema and import new data into the table. But before I could do that I needed to check that no one had updated the table during the last 7 days and no new data had been stored. As the table itself did not have any update field of itself the only other option was to look into the MySQL ‘information_schema’ database.

Usage

Add this to your functions.php

	// Display or Count how many times a post has been viewed.
	// id = the post id and action = display or count

		function arixWp_PostViews( $id, $action ) {

			$axCountMeta 	= 'ax_post_views'; // Your Custom field that stores the views
			$axCount 	= get_post_meta($id, $axCountMeta, true);

			if ( $axCount == '' ) {

				if ( $action == 'count' ) {
					$axCount = 0;
				}

				delete_post_meta( $id, $axCountMeta );
				add_post_meta( $id, $axCountMeta, 0 );

				if ( $action == 'display' ) {
					echo "0 Views";
				}		

			} else {

				if ( $action == 'count' ) {

					$axCount++;
					update_post_meta( $id, $axCountMeta, $axCount );

				} else {

					echo $axCount . ' Views';	

				}

			}	

		}

To count the views add this to your single.php template.

<?php echo arixWp_PostViews( get_the_ID(), 'count' ); ?>

To display the count outside the loop use this:

<?php echo arixWp_PostViews( get_the_ID(), 'display' ); ?>

If you want them to show in the loop use this instead.

<?php echo arixWp_PostViews( $post->ID, 'display' ); ?>

This is a simple widget i created for one theme I was developing, basically it allows you to show your custom taxonomies in your sidebar widgets.

Enjoy

Copy this to your functions.php file

<?php

	function postTypeCrumbs($postType, $postTax) {

		$term 			= get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
		$taxonomy 		= get_taxonomy($term->taxonomy);
		$parents 		= get_ancestors( $term->term_id, $postTax );
		$parents 		= array_reverse($parents);
		$archive_link	= get_post_type_archive_link( $postType );

		echo '<ul class="ax_crumbs">';

		if ($taxonomy)  {
			echo '<li><a href="' . $archive_link . '" title="' . $taxonomy->labels->name . '">' . $taxonomy->labels->name . '</a> &raquo; </li>';
		}

		foreach ( $parents as $parent ) {
			$p 	= get_term( $parent, $postTax );
			echo '<li><a href="' . get_term_link($p->slug, $postTax) . '" title="' . $p->name . '">' . $p->name . '</a> <span>&raquo;</span> </li>';
		}

		if ($term) {
			echo '<li>' . $term->name . '</li>';
		}

		echo '</ul>';

	}
?>

Usage

Paste this whereever you would like the taxonomy to display.

<?php postTypeCrumbs('post type', 'taxonomy name'); ?>
