This thread is resolved. Here is a description of the problem and solution.
Problem: I have a View of a CPT. There will only be 1 result in this View #1. I would like to filter View #2 by taxonomy, where the terms are the same as the terms applied to the results of View 1.
Solution:
Create a duplicate of View 1. In the Loop Output editor, insert the wpv-post-taxonomy shortcode to output the term slugs associated with the post. Use a comma separator. Place this View #3 just before View #2 on the same page. The results should look like this: slug1, slug2, slug3
- Edit View #2. Apply a taxonomy Query Filter, where the term slugs are set by a shortcode attribute. See view-2-filter.png for a similar example. My taxonomy is "Book Taxes" so yours will be a bit different, but the idea is the same.
- Now add the shortcode attribute to the shortcode you used to insert View #2, something like this:
[wpv-view name="view-2-slug" wpvbooktax="term-slug"]
- Test by using a real term slug in the shortcode attribute, and be sure the View is showing the matching results
- Replace the real term slug with the results of View #3 by inserting View #3 shortcode inside the taxonomy shortcode attribute for View #2.
- Add this code to your functions.php file:
add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );
function prefix_clean_view_output( $out, $id ) {
$ids = array( 12345 );
if ( in_array( $id, $ids )) {
$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 View #3. This code strips the unnecessary markup from the results of View #3 so the slugs can be read by the Query Filter of View #2.

Okay thanks. Here's how I would accomplish this.
- Create a duplicate of View 1. In the Loop Output editor, insert the wpv-post-taxonomy shortcode to output the term slugs associated with the post. Use a comma separator. Place this View #3 just before View #2 on the same page. The results should look like this: slug1, slug2, slug3
- Edit View #2. Apply a taxonomy Query Filter, where the term slugs are set by a shortcode attribute. See view-2-filter.png for a similar example. My taxonomy is "Book Taxes" so yours will be a bit different, but the idea is the same.
- Now add the shortcode attribute to the shortcode you used to insert View #2, something like this:
[wpv-view name="view-2-slug" wpvbooktax="term-slug"]
- Test by using a real term slug in the shortcode attribute, and be sure the View is showing the matching results
- Now we need to replace the real term slug with the results of View #3. So insert View #3 shortcode inside the taxonomy shortcode attribute for View #2.
- Finally, add this code to your functions.php file:
add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );
function prefix_clean_view_output( $out, $id ) {
$ids = array( 12345 );
if ( in_array( $id, $ids )) {
$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 View #3. This code strips the unnecessary markup from the results of View #3 so the slugs can be read by the Query Filter of View #2.
Let me know if you run into problems.
The wpv-post-taxonomy shortcode looks like this when you insert it in the View:
[wpv-post-taxonomy type="book-tax" format="slug"]
You can see how to insert this shortcode in the screenshots attached here. In my example the taxonomy is called "Book Taxes" but yours will be something different.
