If/else statement not working as expected

Hello! First off thanks for any support given. It’s much appreciated!

I have the following code:
```
<?php
      if (class_exists('Dynamic_Featured_Image')) {
     global $dynamic_featured_image;
     $featured_images = $dynamic_featured_image->get_featured_images( $postId );
       foreach( $featured_images as $image ) {
          echo "<img src='{$image['full']}' alt='Dynamic Featured Image' />";
       }
     } else {
        echo wp_get_attachment_image( '7457', 'full' );  //fallback single image
      }
      ?>
```
It appears that the class Dynamic_Featured_Image exists even if there’s not a 2nd featured image. Therefore my fallback image in the else statement does not display. How can I check if the class exists AND if there is a 2nd featured image set?

Hi @icommstudies,

You can do something like this:

<?php
if (class_exists('Dynamic_Featured_Image')) {
	global $dynamic_featured_image;
	$featured_images = $dynamic_featured_image->get_featured_images( $postId );
	if (!empty($featured_images)) {
		foreach( $featured_images as $image ) {
		  echo "<img src='{$image['full']}' alt='Dynamic Featured Image' />";
		}
	} else {
		echo wp_get_attachment_image( '7457', 'full' );  //fallback single image
	}
}

Regards,
Ankit
