I am trying to: set following shortcode.
[wpv-view name="az-big-teaser-internal-sites-sommerpiel" selected="11123,[wpv-view name='az-id-selector']"]

i try to show one post fix in the loop and the others randomly. if i use only one view i get only the fixed one. i know i can put the other ones to in the id selected field. but i want that they are comming randomly (selected 49 from 1000 of post) thats why i used the second shortcode. maybe you have a better solution then i tried. maybe its not possible. pls let me know how i can reach this gool. thank you and kind regards. adnan

Sure, this can be accomplished with a bit of custom code. First let me explain what is happening. The inner View shortcode produces output that includes a lot of extra space, some HTML comments, and text that is not necessary for your outer shortcode. This breaks the outer shortcode attribute. So the answer is to add some custom code that will strip out all that unnecessary text from the output of your inner shortcode. Add the following custom code to functions.php:

add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );

function prefix_clean_view_output( $out, $id ) {
  if ( $id == '12345' ) { //Please adjust to your Views ID
    $start = strpos( $out, '<!-- wpv-loop-start -->' );
    if (
      $start !== false
      && strrpos( $out, '<!-- wpv-loop-end -->', $start ) !== false
    ) {
      $start = $start + strlen( '<!-- wpv-loop-start -->' );
      $out = substr( $out , $start );
      $end = strrpos( $out, '<!-- wpv-loop-end -->' );
      $out = substr( $out, 0, $end );
    } else {
      $start = strpos( $out, '>' );
      if ( $start !== false) {
        $out = substr( $out, $start + 1 );
        $end = strpos( $out, '<' );
        $out = trim(substr( $out, 0, $end ));
      }
    }
  }
  return $out;
}

Change '12345' to be the numeric ID of your inner shortcode View (az-id-selector). Then edit your az-id-selector Loop Output. Remove all the spaces and line breaks from this section, and save it.

Now, your inner shortcode should produce output that your outer shortcode can work with. If your shortcode is still not working, you can try the following steps:
- Place the inner shortcode by itself, outside the outer shortcode.
- Look at the output generated by the inner shortcode.
- Is the output what you would expect? It should be a number.
- Take a screenshot of your inner View's Query Filter settings so I can see how it is set up. Is the "selected" attribute defined in the Query Filter settings? I usually see "ids" because it is the default value.

Please let me know the results and we can go from there.
