WP_Query orderby'rand'不起作用 [英] WP_Query orderby 'rand' not working

问题描述

尝试订购一些我随机显示在单个自定义帖子类型页面上的帖子，但它们根本不是随机的. :/

Trying to order some posts I'm displaying on a single custom post type page with random, but they aren't random at all. :/

<?php 
// Grab the taxonomy term slug for the current post 
$terms = get_the_terms( get_the_ID(), 'category-staff' );

if ( $terms && ! is_wp_error( $terms ) ) : 

    $draught_links = array();

    foreach ( $terms as $term ) {
        $draught_links[] = $term->slug;
    }

    $on_draught = join( ", ", $draught_links );
    ?>

    <div class="container hidden-xs">
        <div class="row">
            <div class="col-sm-12">
                <hr />

推荐答案

原来，这与WPEngine有关.他们从服务器禁用了rand()，需要手动启用.

Turns out it was something to do with WPEngine. They disable rand() from the server and it needs to be enabled manually.
