Question

我在这个网站上工作，在那里我为产品构建了一个自定义的帖子类型。我想让客户决定在浏览类别时如何订购显示的产品。我已经在WordPress默认主题上测试了以下脚本并且它可以工作，但现在当我将它移动到我自己的主题时它不起作用。我得到的只是一条消息，说不能找到任何帖子。

以下是我的代码的外观：

<?php

get_header();

$order_by = $_GET['order_by'];
$order = $_GET['order'];

switch ($order_by) {
    case 't':
        $ob = 'title';
        break;

    case 'i':
        $ob = 'ID';
        break;

    case 'r':
        $ob = 'rand';
        break;

    default:
        $ob = 'date';
        break;
}

switch ($order) {
    case 'a':
        $o = 'asc';
        break;

    default:
        $o = 'desc';
        break;
}

global $query_string;
$cat_posts = new WP_Query($query_string.'&orderby='.$ob.'&order='.$o);

?>

<?php if ( $cat_posts->have_posts() ) : ?>

  <div class="container margin-top">

Answer 1

可以产生影响的是你在哪里调用get_header(); - 看看默认的WP主题和你的。 <{1}}应该是

之后的
get_header();

同时将$cat_posts = new WP_Query($query_string.'&orderby='.$ob.'&order='.$o);放在页面的最开头。
