Fix category ID selector in WordPress.tv editor

[nilovelez]

In one of the last versions of WordPress, the code for each checkbox in the categories meta tag of the classic editor has changed from:

<input value="107686937" type="checkbox" name="post_category[]" id="in-category-107686937">

to:

<input value="107686937" type="checkbox" name="post_category[]" id="in-category-107686937-2">

That "-2" breaks the selector of the javascript used in the WPTV editor to apply categories.

The change has tobe made in line 523 of ​https://meta.svn.wordpress.org/sites/trunk/wordpress.tv/public_html/wp-content/themes/wptv2/plugins/wordpresstv-anon-upload/anon-upload.php

I include the required patch, with base in
​https://meta.svn.wordpress.org/sites/trunk/wordpress.tv/public_html/wp-content/themes/wptv2/

Broken category links in the editor

Why has the -2 appeared here? Do you have any link to the changeset / etc that's caused it? Just to avoid changing this only for it to reappear sometime.

I can't find the changeset, but the HTML of the elements in the categories metabox is now like this:

<li id="in-category-2757063-1">
    <label class="selectit">
        <input value="2757063" type="checkbox" name="post_category[]" id="in-category-2757063-2" checked="checked"> 2025
    </label>
</li>

The <li> tag has now a -1 and the checkbox a -2 to prevent duplicate ids

The javascript from the editor uses that id to query the element, grab the title and check it when clicked.

There's a hundred better ways of doing this, but for now it's just a hotfix until we have a new version.
