We wanted a simple way to display our client list using Custom Fields. Using built-in WordPress functions, it is pretty simple to pull information from Custom Fields. With Custom Field structure like this:

Name: client
Value: Name|Work_Done|Description|URL

You can use the get_post_meta() function to loop through all of the ‘client’ fields and pull the value for each and display to your page.

ORIGINAL CODE:

<?php
	$allOptions = get_post_meta($post->ID, 'client', false);
	if($allOptions) {

		foreach ($allOptions as $option) {
			$fullValue = explode ("|", $option);
			$name = $fullValue[0];
			$work = $fullValue[1];
			$text = $fullValue[2];
			$url = $fullValue[3];
		}

	}
?>

The problem comes if you want to control the way the output is displayed. The get_post_meta() function does not provide a SORT property. So in order to control the order of display, we simply added an additional component to the VALUE field, a ‘sort order’.

Name: client
Value: Sort|Name|Work_Done|Description|URL

Rather than just display the information in the initial foreach() loop, we stored the data into a new array, based on the SORT item for use later.

NEW CODE:

<?php
	$client_array = array();
	$allOptions = get_post_meta($post->ID, 'client', false);
	if($allOptions) {
		foreach ($allOptions as $option) {
			$fullValue = explode ("|", $option);
			$order = $fullValue[0];
			$client_array[$order] = $option;
		}
	}
	rsort($client_array, SORT_NUMERIC);
?>

With the data now stored in an sorted array, we can now loop through the new array and display the information in any order we want.
