将PHP脚本添加到wordpress的树枝上

Question

im frecuent user of this forum and always find answers from other users, but this time i need to ask my own question.

At this moment im editing a wp template based on twig that i bought, right now im facing a fancybox gallery which just call the first image, and i need to add the gallery rel to the other images included in the post. i already found the missing code which call the rest of images from the post ID, but i dont know how to express it by the twig structure and incorporate it to the original code of the page

this is the code which display the gallery:

 {% if wp.get_post_meta(post.ID, '_property_slides', TRUE) %} <div class="carousel property"> <div class="preview"> <a href="{{ wp.get_post_meta(post.ID, '_property_slides', TRUE).0.imgurl }}" class="fancybox"> <img src=" {{ wp.get_post_meta(post.ID, '_property_slides', TRUE).0.imgurl }}" alt=""> </a> // the php code expressed on twig goes here // </div> <!-- /.preview --> <div class="content"> <ul> {% for slide in wp.get_post_meta(post.ID, '_property_slides', TRUE) %} {% if loop.first %} <li class="active" > {% else %} <li> {% endif %} <img src="{{ slide.imgurl }}" alt=""> </li> {% endfor %} </ul> <a id="carousel-prev" href="#">{{ wp.__('Previous', 'aviators') }}</a> <a id="carousel-next" href="#">{{ wp.__('Next', 'aviators') }}</a> </div> <!-- /.content --> </div><!-- /.carousel --> {% endif %} 

This is the php code i need to implement on twig

 add_filter('wp_get_attachment_link','add_gallery_id_rel'); function add_gallery_id_rel($link){ global $post; return str_replace('<a href', '<a rel=”galeria'. $post->ID .'” href', $link); } 

I really appreciate if you can help me with this (sorry about my weird english)

That code is a filter applied to the regular Wordpress functions, you are using a Twig Wrapper so that code won't work for you.

Try modifying the twig loop.

{% for slide in wp.get_post_meta(post.ID, '_property_slides', TRUE) %}
  #... rest of the code
  <a rel="galeria{{ post.ID }}" href="{{ slide.imgurl }}">
    <img src="{{ slide.imgurl }}" alt="">
  </a>
  #... rest of the code
{% endfor %}

Skip the first slide using slice :

{% for slide in wp.get_post_meta(post.ID, '_property_slides', TRUE)|slice(1) %}
#... rest of the code same as above
