WordPress function 调用页面内容的特定部分

Question

I'm working on a simple website using WP and i don't know a way to call a specific part of the content. I'll try to explain myself better.

Using the function:

the_content(); in the.php file i can call the whole page content.
I'm using a shortcode that simply create a div and i want to call in the.php file only the div created so that i can put it inside other divs etc.
Is there a function like the_content(); that only calls the shortcode?

Or, without using the shortcode, is there a way to call a portion of the page content using a WP function?

Here's the code:

in the function.php i have:

function create_div($atts, $content = null) {

      extract( shortcode_atts( array(
          'class' => '',
          'id' => '',
      ), $atts ) );

      $class = $class ? " class=\"$class\"" : NULL;
      $id = $id ? " id=\"$id\"" : NULL;

      return "<div$class $id>$content</div>";
  }
  add_shortcode('div', 'create_div');

And in the page.php i want to do something like this:

<div>
  <?php the_shortcode(); ?>
</div>

Thanks, Andrea

You can use a shortcode directly in php using the do_shortcode() function - see here: https://developer.wordpress.org/reference/functions/do_shortcode/

You can also try get_the_content() to get everything into a variable and then extract what you need from there - see here: https://developer.wordpress.org/reference/functions/get_the_content/
