Error 500

Resolved

(@semperaye)

Hi. I keep getting either: “The snippet has been deactivated due to an error on line 4: syntax error, unexpected ‘$html’ (T_VARIABLE)”, or an error 500 when I add the following snippet:

add_shortcode('post_cats', 'sa_show_cats');
function sa_show_cats() {
  $cats = wp_get_post_categories( get_the_ID(), ['fields'=>'all',]);
  $html = array();
  foreach ( $cats as $cat ) {
    $url = site_url("/category/{$cat->slug}/");
    $html[] = "<a class=\"sa-cat-links\" href=\"$url\">{$cat->name}</a>";
  }
  return implode( $html, ', ');
}

Hi,

I can’t see any syntax issues in the snippet you posted. The only thing I can think of is perhaps there’s an issue with the use of the short array syntax on line 3?

Perhaps you could try switching out that line with this:

$cats = wp_get_post_categories( get_the_ID(), array( 'fields' => 'all' ) );

Thank your taking a look into this for me! Unfortunately your suggested change in code did not fix the error 500.

Unfortunately, I can’t really say for sure what might be causing the issue without more information, but I’ve rewritten the snippet slightly – perhaps you could try this out and see whether it works?
```
add_shortcode( 'post_cats', function () {
	$cats = wp_get_post_categories( get_the_ID(), array( 'fields' => 'all' ) );
	$html = array();

	foreach ( $cats as $cat ) {
		$html[] = sprintf(
			'<a class="sa-cat-links" href="%s">%s</a>',
			get_term_link( $cat, 'category' ),
			$cat->name
		);
	 }

	return implode( $html, ', ' );
} );
```

Shea,

THANK YOU!! This works perfectly! I wonder what the issue was??!

it’s difficult to say, but I suspect it has to do with escaping double quotation marks on line 7. sprintf() is a great alternative for these situations.
