After the upgrade does not work the filter categories

  • I need for users (not administrators) to exclude from the site search a particular category. Code written, all worked fine until the latest updates. On what exactly update stopped working I do not know. Most likely 3.9 or 4.0.

    Worked the following code:

    function search_filter ($query) {
???? if (($ query-> is_search) and! current_user_can ('administrator')) {
?????? $query-> set ('cat', '-14');
???? }
}
add_action ('pre_get_posts', 'search_filter');

    $query-> set (‘category__not_in’, ’14’); does not work
    add_filter – does not work

    Code is inserted into the functions.php of the theme.

    Anyone know why suddenly stopped working this code?

    Understood. Custom Fields Search plugin bypassed this hook. How to make them work together until I found …

    have any ideas to make friends with a hook and a plugin?
    or how to edit the plugin to exclude the category you want to read more …

    I don’t see where the plugin is intentionally bypassing ‘pre_get_posts’, but it does significantly alter the resulting query in a way that could possibly corrupt the initial query string.

    One solution would be for you to alter the same query string after the plugin is finished with it. The ‘posts_request’ filter would allow this, or filtering ‘posts_join’ and ‘posts_where’ with a priority parameter greater than 10.

    I don’t know how to actually write a query to exclude a category, but you could temporarily disable the plugin to see how WP does it using your original code and viewing the results in one of the filters I mentioned. Then add in the same query strings after the re-enabled plugin has done it’s part.

    A better solution would be to correct whatever the plugin is doing to corrupt the initial query string. (If that is indeed the problem, I’m only speculating here) The time to debug the plugin is more than I’m willing to commit to. That responsibility should be taken by the plugin author. A plugin that does not work with ‘pre_get_posts’ is inherently flawed IMO.

    Plugin authors apparently believe that this is not an error ?? on the page support them have issues.

    To be fair, the problem is likely an inter-plugin (or theme) conflict that the authors are unable to reproduce, thus their stance that there is no error. Unless you can offer a path to follow on a clean fresh installation with only the one plugin installed on a default theme plus you one code snippet that reliably produces the error, you are unlikely to get any traction with the authors.

    Even so, they can always take the stance that you shouldn’t do that with their plugin, it’s outside of their design parameters. You’re always free to fork the plugin with proper attribution.

    Without author support, your best approach is to come in and alter the query after the plugin is finished with it. I really hate manipulating queries this way, it seems inherently weak, but it is your best option at this point. Short of binning the plugin at least.

    I turned off the plugin yet. Has added code to the template to regular search looking for the same on custom fields. Specific sample in the fields did not, the request goes through all fields. While this is enough for me.
