Digging into WordPress

You know that you can target single-view pages with the conditional tag, is_single():

<?php
if(is_single()) {

	// do something

} else {

	// do something else

}
?>

This is a great way to conditionally apply styles, scripts, and markup to single-view pages.

But did you know about the conditional tag, is_singular()? The is_singular() tag enables you to target single-view pages, regular page pages, and attachment pages all in one fell swoop.

So, instead of writing something like this:

<?php
if(is_single() || is_page() || is_attachment()) {

	// do something

} else {

	// do something else

}
?>

We can write this instead:

<?php
if(is_singular()) {

	// do something

} else {

	// do something else

}
?>

The is_singular() tag is what’s known as a “boolean” function, meaning that it returns one of two values, either TRUE or FALSE. No parameters are associated with this tag.

Now you know :)
