[英]Change Wordpress Loop Order from 'desc' to 'asc' with click or dropdown
我是PHP新手,需要执行以下操作:
•创建一个下拉菜单或链接,以在选择或单击时将WordPress循环从“ desc”更改为“ asc”。
这是我的循环代码:
<?php
global $wp_query; $post; $post_id = $post-> ID;
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
rewind_posts();
$temp = $wp_query;
$wp_query = NULL;
$post_type = 'post'; // change this to the post type you want to show
$show_posts = '20'; // change this to how many posts you want to show
$category_name = 'used-cars'; // change this to the category name you need
$order_by = 'meta_value_num';
$meta_key = 'price';
$order = 'desc'
?>
<?php $wp_query = new WP_Query( 'category_name=' . $category_name . '&post_type=' . $post_type . '&posts_per_page=' . $show_posts . '&paged=' . $paged . '&orderby=' . $order_by . '&meta_key=' . $meta_key . '&order=' . $order ); ?>
<?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
<div style="width: 670px; height: 170px; border-bottom: 3px solid #ccc; width: 100%; padding-top: 20px;">
<!-- POST THUMB -->
<div style="float: left; width: 150px;">
<?php if ( has_post_thumbnail() ) : ?>
<a href="<?php the_permalink() ?>"><?php the_post_thumbnail( 'thumbnail' ); ?></a>
<?php else : ?>
<div style="width: 150px; height: 150px; border: 1px solid #efefef;">
<p style="text-align: center; margin-top: 60px;">No Pictures Available</p>
</div>
<?php endif; ?>
</div>
<!-- POST CONTENT RIGHT -->
<div style="float: left; margin: 0px 0 0 20px; width: 450px;">
<div style="float: left; width: 245px; height: 150px;">
<!-- POST INNER LEFT -->
<h2 style="margin-bottom: 20px; font-size: 16px;"><a class="loop-link" href="<?php the_permalink() ?>"><?php the_title() ?></a></h2>
<div style="float: left; width: 70px; height: 120px;">

<p style="font-size: 12px;"><?php the_field('mileage'); ?></p>
<p style="font-size: 12px;"><?php the_field('gearbox'); ?></p>
</div>
</div>
<!-- POST INNER RIGHT -->
<div style="float: right; margin: 0; width: 170px; height: 150px; border-left: 1px solid #efefef; text-align: right;">

该代码用于汽车网站,您可以在此处查看页面:

我已经花了几天时间寻找解决方案,但是,我还没有找到任何解决方案。 再次,正如我所说,我是PHP的新手,所以任何帮助或建议都将非常有用。 有什么想法吗,网友?
Slainté。
使用以下代码,现在使用filename.php?order = desc或filename.php?= order = asc调用文件
它会改变
<?php
global $wp_query; $post; $post_id = $post-> ID;
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
rewind_posts();
$temp = $wp_query;
$wp_query = NULL;
$post_type = 'post'; // change this to the post type you want to show
$show_posts = '20'; // change this to how many posts you want to show
$category_name = 'used-cars'; // change this to the category name you need
$order_by = 'meta_value_num';
$meta_key = 'price';
$order = ($_GET["order"]);;
?>
<?php $wp_query = new WP_Query( 'category_name=' . $category_name . '&post_type=' . $post_type . '&posts_per_page=' . $show_posts . '&paged=' . $paged . '&orderby=' . $order_by . '&meta_key=' . $meta_key . '&order=' . $order ); ?>
<?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
