Conditionally Load WordPress Pages

Need to load a WordPress page conditionally? For example, perhaps you need a “special” page to appear for search results? Yes? This simple PHP/JavaScript solution may be just what the doctor ordered!

Simply replace “condition” with the required condition (or delete the if (condition) {} qualifier entirely), and then change the path and file names to suit your specific needs:

<?php
if (condition) {
	
	echo ("
		<script type=\"text/javascript\">
		<!--//--><![CDATA[//><!--
		
		parent.location='http://www.domain.com/path/to/file.html';
		
		//--><!]]>
		</script>
	");
	
} else {
	
	echo ("
		<script type=\"text/javascript\">
		<!--//--><![CDATA[//><!--
		
		parent.location='http://www.domain.com/path/to/other-file.html';
		
		//--><!]]>
		</script>
	");
	
}
?>

Specifically, I employ the following trickery in my Killer WordPress theme:

.
.
.
<?php endwhile; else: ?>
	
	<?php echo ("
		<script type=\"text/javascript\">
		<!--//--><![CDATA[//><!--
		
		parent.location='http://example.com/subdirectory/?p=58';
		
		//--><!]]>
		</script>
	"); ?>
	
<?php endif; ?>

The previous code chunk returns a specially designed search results page that is specifically tailored to suit the Killer theme. Works wonders.

Spent some time refreshing my business portfolio at MonzillaMedia.com :)
Tried lots of apps for making animated GIFs from screen captures, so far Kap is my favorite. For example the GIF on this post.

Air finally clearing here in WA. Feeling grateful to breathe again. #oxygenmatters
Past week here in WA state has been hellish. So much smoke, like living in a chimney.
Now in September, I’m where I wanted to be in March.
