PHP Error with 7.3

  • Having upgraded to PHP 7.3 I’m getting the following errors:

    NOTICE: wp-includes/class-wp-comment-query.php:853 – compact(): Undefined variable: limits
    require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), include(‘/themes/graphene/page.php’), get_template_part, locate_template, load_template, require(‘/themes/graphene/loop-page.php’), the_content, apply_filters(‘the_content’), WP_Hook->apply_filters, bp_replace_the_content, apply_filters(‘bp_replace_the_content’), WP_Hook->apply_filters, BP_Members_Theme_Compat->single_dummy_content, bp_buffer_template_part, bp_get_template_part, bp_locate_template, load_template, require(‘/plugins/buddypress/bp-templates/bp-legacy/buddypress/members/single/home.php’), bp_get_template_part, bp_locate_template, load_template, require(‘/themes/graphene-child/buddypress/members/single/profile.php’), bp_get_template_part, bp_locate_template, load_template, require(‘/plugins/buddypress/bp-templates/bp-legacy/buddypress/activity/activity-loop.php’), bp_has_activities, BP_Activity_Template->__construct, bp_activity_get, BP_Activity_Activity::get, apply_filters(‘bp_activity_get_where_conditions’), WP_Hook->apply_filters, bp_docs_access_protection_for_activity_feed, BP_Docs_Access_Query->get_comment_ids, get_comments, WP_Comment_Query->query, WP_Comment_Query->get_comments, WP_Comment_Query->get_comment_ids, compact

    You can see from the trace that these stem from BP Docs, the PHP manual for compact() has a note to say from 7.3 strings that are not set will be warned. I’m uncertain if this is a BP Docs issue or if it’s something missing in WP since I can’t see a problem with the originating get_comments() call.

    Thanks, @venutius, for flagging this issue. We’ll look into it. ??

    It’s a WP core issue.

    It’s an issue in WP core, at least 4.9.10 that I’m using

    I just set up a fresh test installation using PHP 7.3 and the latest WP, BP and BP Docs and I’m not encountering any errors or even notices.

    If someone is seeing errors still, please let me know how I can recreate.

    Thanks!

    It happens to me using PHP 7.3 and WordPress 4.9.10.

    It is a core issue. That said. I fixed it locally by adding the following code just belown line 820 of wp-includes/class-wp-comment-query.php

    $groupby = ”;

    It may not seem like a big deal, but it’s a very visible issue when you use comments on your site. This error notice also appears in the dashboard.

    Thanks! It sounds like the fix is to upgrade to a newer version of WP, then?
