[Resolved] Can I exclude with a custom meta field from a list?

Thanks for your quick answer, Tom,

Well, not ideal since we’re using several taxonomies and in each one, the post We want to exclude from the list share some other term(s) with others that must show up. Of course, we can create another taxonomy and apply to each and one of the posts (some 800) the appropriate term.

If we can’t exclude employing Custom post Field we’ll try this approach.

Thanks, Tom

Hello, Tom (again…),

It’s been a while since your last message, it’s my fault for not answering you, sorry. I don´t remember very well but I think I found a workaround for the first issue.
BUT, here I am with a new question involving the same filter (wpsp_query_args) you introduced in version 1.2.0.
I’m trying to filter a taxonomy in a list (id 50023) according to the meta key ‘idioma’ and the value ‘english’ with compare ‘!==’.. but it doesn’t work.
Can you help me, please ? That’s the code I’ve placed in functions.php:

add_filter(
  "wpsp_query_args",
  function ($args, $settings) {
    if (50023 === (int) $settings["list_id"]) {
      $args["meta_query"] = [
        [
          "key" => "idioma",
          "value" => "catala",
          "compare" => "!==",
        ],
      ];
    }

    return $args;
  },
  10,
  2
);

Thanks

Hi Elvin,

I’m sorry to say that it’s not working…

On the other hand, I’ve tried another more classical approach which is using the action “pre_ger_post()”:

add_action("pre_get_posts", "etdla_pre_world_arts");
function etdla_pre_world_arts($query)
{
  if (!is_page("world-arts")):
    return;
  endif;

  if (!is_admin() && $query->query_vars["post_type"] === "post"):
    $meta_query = [
      [
        "key" => "idioma",
        "value" => "catala",
        "compare" => "!=",
      ],
    ];
    $query->set("meta_query", $meta_query);
    $query->set("meta_key", "idioma");
  endif;
}

But that’s not ideal since I’m not taking advantage of the plugins features.

Thanks

Do you mean this?:

function etdla_pre_world_arts($query)
{
  if (!is_page("world-arts")):
    return;
  endif;

  if (!is_admin() && $query->query_vars["post_type"] === "post"):
    $meta_query = [
      [
        "key" => "idioma",
        "value" => "catala",
        "compare" => "NOT EXISTS",
      ],
    ];
    $query->set("meta_query", $meta_query);
    $query->set("meta_key", "idioma");
  endif;
}

Then outputs no posts

Hi there again,

No, I didn’t, but now I’ve done and got the same results as shown in this screenshot:
https://snipboard.io/kAqPjZ.jpg
The change has been made in
/wp-show-posts/wp-show-posts.php
as you can see here:
https://snipboard.io/A1k8TI.jpg
but to no avail.

Elvin, in fact the page is working with “pre-get-posts”, and I’m taking too much of your time. I’m really sorry. You can mark this ticket as closed if you want.

I’ll give it a try
Thanks very much
