With the redesign of the Ei Site, we wanted to take advantage of certain features native to WordPress, one of which was Custom Fields.
Having a custom web design based on the needs of your particular business and customers optimizes conversion rates of site visitors, a key aspect of growing your business and brand presence online
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($allOptions) {foreach($allOptionsas$option) {$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($allOptions) {foreach($allOptionsas$option) {$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.
