PHP Echo中的PHP代码

I have a Wordpress site using Advanced Custom Fields and need to insert the shortcode value they enter in a PHP template file. I need to insert this code

<?php the_field('image_gallery'); ?>

into this PHP echo

<?php echo do_shortcode('CODE IN HERE'); ?>

So that it can output the shortcode the user enters in the PHP template.

Thank you!

The only way to do this would be to use get_field() to return the value stored in image_gallery to the do_shortcode() function:

<?php 
    $image_gallery_shortcode = get_field('image_gallery');
    echo do_shortcode( $image_gallery_shortcode ); 
?>
