How to Split WordPress Custom Field Values

Are you looking for a way to split WordPress custom field value? While there’s probably a plugin for this, we have created a quick code snippet that you can use to split WordPress custom field value in WordPress.

We have been aware of WordPress Post Thumbnail Feature for a while now, but in some cases one is just not enough. This is a cool snippet for expanding WordPress post thumbnail output with the help of custom fields to add more thumbnails. Although there are plugin alternatives, this is a very quick method for something simple, short, and sweet.

So lets say you have a portfolio page and you want to display a couple of thumbnails, say 4(or more). This is what you can do:

Create a custom field value of ‘Images’ and insert the links to your images in the textarea. Each link must be on a new line. Then use this snippet.

Instructions:

All you have to do is add this code to your theme’s single.php file:

<?php
$images = get_post_meta($post-&gt;ID,‘Images’);
$images = nl2br($images[0]);
$images = explode(‘&lt;br /&gt;’,$images);
foreach($images as $src) {
	echo "<img src="".trim($src)."" />";
}
?>
