# Echo Custom Field Key Inside PHP Echo Statement

 * Hopefully someone far more experienced working with theme files can help me.
 * I need to echo a custom field value inside of an already existing echo statement
   in my theme files. It seems straight-forward enough, but no amount of Googling
   has helped.
 * Here’s the code I’m working with:
 *     ```
       <?php $product_id = get_post_meta($post->ID, 'product_id', true);if ($product_id) { ?>
       <?php echo get_button_code_for_product(<?php echo $product_id; ?>); ?>
       <?php} ?>
       ```
   
 * The original line I started with was
 *     ```
       <?php echo get_button_code_for_product(1); ?>
       ```
   
 * I need to be able to echo each post’s product_id into the parentheses of the 
   above code.
 * Any help? Thanks in advance!

 * You can’t echo inside an echo and guessing on what you’re trying to achieve above,
   you don’t have to. Also, you have php tags inside existing php tags.
 * This is how I would write it:
 *     ```
       <?php
          $product_id = get_post_meta($post->ID, 'product_id', true);
   
          if ( $product_id ) {
             echo get_button_code_for_product( $product_id );
          }
       ?>
       ```
