如何将带有参数的 WordPress 简码传递给模板 [英] How pass WordPress shortcode with Parameters to template

问题描述

我有带有子主题的模板，我编辑子模板 function.php

I have template with child theme and I edit child template function.php

目标是创建具有参数和部分模板文件的短代码

Goal is create short code witch will have parameters and part of template file

我的函数是这样的:

function my_shortcode($atts = array() ) {
    extract(shortcode_atts(array(
        'catid' => '5'
    ), $atts));
    ob_start();
   include(get_template_part('mynews-temp'));
    return ob_get_clean();
}
add_shortcode('mynews', 'my_shortcode');

[mynews catid="5"] 短码输出必须是cat id 5的新闻查询

[mynews catid="5"] short code output must be news query with cat id 5

这是带有查询的模板部分

this is template part with query

<?phpif ( ! defined( 'ABSPATH' ) ) {exit( 'Direct script access denied.' );}
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'mynews',
'tax_query' => array(
array(
'taxonomy' => 'newstypes',
'field' => 'tag_ID',
'terms' => array('$catid')
),),));
if( $posts ): ?>
<?php foreach( $posts as $post ):
setup_postdata( $post );?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a><
<?php endforeach; ?>
<?php endif;    wp_reset_postdata(); ?>

不行，找不到错误所在

附言当我使用子模板时，女巫是正确的:

P.S. witch is correct when i use child template:

 include(get_template_part('mynews-temp'));
 or  include(locate_template('mynews-temp'));

推荐答案

您可以包含这样的模板部分:get_template_part('mynews-temp').无需include，什么都不做.

You can include the template parts like this: get_template_part('mynews-temp'). No need to include, that does nothing.

您的其余代码运行良好.我唯一可以推荐的是简化您的代码，并获取所有常规 post 以查看问题是否出在 tax_query 中:

The rest of your code works perfectly. The only thing I could recommend is to simplify your code and just get all the regular posts to see if the problem is in the tax_query:

<?php
if ( ! defined( 'ABSPATH' ) ) {exit( 'Direct script access denied.' );}
$posts = get_posts(array(
    'posts_per_page' => -1,
    'post_type' => 'post',
    
));
//     'tax_query' => array(
//         array(
//             'taxonomy' => 'newstypes',
//             'field' => 'tag_ID',
//             'terms' => array('$catid')
//         ),),));
if( $posts ): ?>
<?php foreach( $posts as $post ):
setup_postdata( $post );?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a><
<?php endforeach; ?>
<?php endif;    wp_reset_postdata(); ?>
