title: Woocommerce: add ACF field for product additional information
body: <p>Good evening,</p>
  <p>I tried to add an ACF field in the admin &gt; ad product page, in order to add easier product additional information (under the default Woocommerce product specifications: weight, size).
  I added the following code in the function.php child theme, but it didn't give result, and I've a message:</p>
  <blockquote>
  <p>Vos modifications de code PHP ont été annulées en raison d’une erreur

  syntax error, unexpected token &quot;&lt;&quot;, expecting end of file</p>
  </blockquote>
  <p>Can you help me? This is the code I tried to add. Thank you in advance.</p>
  <pre><code>&lt;?php if ( $editeur ) : ?&gt;
      &lt;a href=&quot;&lt;?php echo esc_url( get_term_link( $editeur ) ); ?&gt;&quot;&gt;&lt;?php echo esc_html( $editeur-&gt;name ); ?&gt;&lt;/a&gt;
  &lt;?php endif; ?&gt;
  &lt;?php the_field( 'date_de_parution' ); ?&gt;
  &lt;?php the_field( 'nombre_de_volumes' ); ?&gt;
  &lt;?php the_field( 'nombre_de_pages' ); ?&gt;
  &lt;?php the_field( 'isbn' ); ?&gt;
  &lt;?php $presentation = get_field( 'presentation' ); ?&gt;
  &lt;?php if ( $presentation ) : ?&gt;
      &lt;a href=&quot;&lt;?php echo esc_url( get_term_link( $presentation ) ); ?&gt;&quot;&gt;&lt;?php echo esc_html( $presentation-&gt;name ); ?&gt;&lt;/a&gt;
  &lt;?php endif; ?&gt;
  &lt;?php the_field( 'illustrateur' ); ?&gt;```
