[Solved] Allow and tags | Do not remove classes on edit

Hi @tetrakern

Read this doc please - https://wpdiscuz.com/docs/codex/filters/wpdiscuz_allowedtags/

You can add custom tags with its attributes using the hook provided in this doc.

Unfortunately, this doesn't work. Provided I did it right.

add_filter( "wpdiscuz_allowedtags", function ( $allowedtags ) {
  $allowedtags["ins"] = true;
  $allowedtags["del"] = true;
  return $allowedtags;
});

The visual editor will reject or rather vandalize the appended HTML, remove all tags including their content and only leave a plain block. I didn't test it for the non-visual editor but that's not what I want to use. I think the Quill Editor does not care for the allowed tags by this filter.

@tetrakern,

Please use this code:

add_filter( "wpdiscuz_allowedtags", function ( $allowedtags ) {
  $allowedtags["ins"] = true;
  $allowedtags["del"] = true;
  return $allowedtags;
});
add_action("wpdiscuz_front_scripts", function ($options) {
    if ($options->form["richEditor"] === "both" || (!wp_is_mobile() && $options->form["richEditor"] === "desktop")) {
        if ($options->general["loadComboVersion"]) {
            wp_add_inline_script("wpdiscuz-combo-js", quillAddNewTagSupport(), "after");
        } else {
            wp_add_inline_script("quill", quillAddNewTagSupport(), "after");
        }
    }
});
function quillAddNewTagSupport() {
    ob_start();
    ?>
    let Inline = Quill.import('blots/inline');
    class wpdQuillDel extends Inline {}
    wpdQuillDel.blotName = 'del';
    wpdQuillDel.tagName = 'DEL';
    Quill.register(wpdQuillDel, true);
    class wpdQuillIns extends Inline {}
    wpdQuillIns.blotName = 'ins';
    wpdQuillIns.tagName = 'INS';
    Quill.register(wpdQuillIns, true);
    <?php
    return ob_get_clean();
}

It should work fine. 

Please don't forget to delete all kind of caches before checking. 

Thank you for the effort; seems to be more involved than one might expect. Unfortunately, it still doesn't work. The ql-editor still sanitizes the tags away -- I could not test if they are saved and loaded, obviously.

I did clear all caches I could think of, deactivated any plugins like WP Super Cache and Autoptimize to be sure, turned wpDiscuz off and on, cleared the browser data, hard reloaded, used a different browser, used a different computer, used a different WordPress installation on a live test server.

I'm to 99% sure it was not a caching issue.

@tetrakern,

Have you put the code in the functions.php file? We've checked the code several times, it works fine in our case. 

Please note the code works only for <del> u <ins> tags. Probably you've not tested for those tags. 

It is inside the functions.php and I did test it for <del> and <ins>. After all, that's how the diff-match-patch script works.

What the script is trying to append:

What appears:

I also get "Uncaught ReferenceError: Quill is not defined". This might be the issue.

Yep, I think I found the error. It's Autoptimize that aggregates all scripts and apparently causes the script to be executed before it is ready. Or whatever. I turned it off before and it changed nothing, but oh well. I'll find a solution for that myself. Thanks for the help.

For those who might encounter a similar problem with the plugin: add "wp-content/plugins/wpdiscuz" to the "Exclude scripts from Autoptimize" list.

Thank you for sharing the solution.
