如果 post 属于多个类别并且我想在 Genesis post_meta 中显示主要类别
If a post belongs to a many categories and I want to show a primary category in Genesis post_meta
在 https://broadly.vice.com/en_us 上,如果他们的 post 属于多个类别,则他们会显示一个主要类别。
如何在 post 乘以 post 的基础上选择要在 Genesis Child 主题的 post_meta 中显示的主要类别?
从这个 post 日期开始,安装 Trunk version of CMB2(不是插件)。

将以下内容放入您的 functions.php 或者,更好的是,您的函数插件。不要添加开头 php。在许多位置更改 yourprefix_
。
<?php
//don't add

* Requires CMB2 TRUNK branch NOT the plugin from the repo
* Install CMB2-trunk.zip via plugin interface or incorporate in your theme, read their docs

function yourprefix_primary_category_selection() {
$prefix = 'yourprefix_';
$cmb_demo = new_cmb2_box( array(
'id' => $prefix . 'metabox',
'title' => esc_html__( 'Primary Category', 'yourtextdomain' ),
'object_types' => array( 'post', ),
'context' => 'side',
'priority' => 'low',
'show_names' => false,
) );
$cmb_demo->add_field( array(

if ( genesis_html5() )

这是简单的解决方案。
使用 SEO Yoast 免费插件 https://wordpress.org/plugins/wordpress-seo/。当有多个类别分配给 post.
时,这有助于您将任何类别设为主要类别
主猫选择见插件界面:
然后在你的 WP 主题中,在函数文件中有以下函数,然后你可以使用在任何地方回显类别名称:<?php echo taxo_primary_term_name; ?>
// wp seo yoast get primary category name
function taxo_primary_term_name($taxo){
$wpseo_primary_term = new WPSEO_Primary_Term($taxo, get_the_ID());
$wpseo_primary_term = $wpseo_primary_term->get_primary_term();
return $wpseo_primary_term = get_term($wpseo_primary_term)->name;
}
