Conditional Value When No Taxonomy Terms Assigned

Resolved

(@dpipitone)

I have set up a custom Taxonomy for “Now Pouring” and I would like to know how to display a message “Not available right now.” when there aren’t any values assigned.

Right now, my page’s template is using:

<?php if ( get_the_term_list( $post->ID, 'portfolio_category', '', '<br />', '' ) ) : ?>
							<div class="project-info-box">
								<h4><?php esc_html_e( 'Now Pouring At:', 'fusion-core' ) ?></h4>
								<div class="project-terms">
									<?php echo get_the_term_list( $post->ID, 'pouring_at', '', '<br />', '' ) ;?>
								
 
								</div>
							</div>

						
						<?php endif; ?>

Can anyone help?

Thanks in advance

Should be as simple as providing an else portion of your if statement, like so:
```
<?php 
if ( get_the_term_list( $post->ID, 'portfolio_category', '', '<br />', '' ) ) : ?>
	<div class="project-info-box">
		<h4><?php esc_html_e( 'Now Pouring At:', 'fusion-core' ) ?></h4>
		<div class="project-terms">
			<?php echo get_the_term_list( $post->ID, 'pouring_at', '', '<br />', '' ) ;?>
		</div>
	</div>
<?php
else :
?>
Do something.

<?php endif; ?>
```
Also, I would recommend using something like https://codex.wordpress.org/Function_Reference/has_term for your if statement check. You can check for ANY term in the taxonomy by passing an empty string for the first argument.
```
if ( has_term( '', portfolio_category', $post->ID ) ) {
```

Hey, Michael.

I tried this out, but when I remove the taxonomy values, it doesn’t display the message:
```
<?php 
if ( get_the_term_list( $post->ID, 'portfolio_category', '', '<br />', '' ) ) : ?>
	<div class="project-info-box">
		<h4><?php esc_html_e( 'Now Pouring At:', 'fusion-core' ) ?></h4>
		<div class="project-terms">
			<?php echo get_the_term_list( $post->ID, 'pouring_at', '', '<br />', '' ) ;?>
		</div>
	</div>
<?php
else :
?>
echo "Not available";

<?php endif; ?>
```

Part of why I recommended changing to has_term for your if statement. Technically the way you’re doing things now is likely producing *some* sort of output, which is resulting in the first half evaluating to true. Essentially, it could be testing for a true condition with just “<br/”, aka if ( '<br />' ) { which will evaluate to true cause it has a value of some sort. “Truthy” value if I recall technical terms correctly. The has_term function will return only boolean true and false values making it more consistent and reliable.
