自定义帖子类型中自定义分类的条件标签 [英] Conditional Tags for Custom Taxonomy in Custom Post Type

问题描述

我希望您对此给出一个切实可行的答案（可能对您来说是个简单的问题）。我创建了一个名为（例如：） Cuspost的自定义帖子类型，并且在名为 Custax的Cuspost中创建了自定义分类法。然后我有了分类法：在Custax中有 A Custax和 B Custax。

I do hope you give me a practical answer for this (maybe simple problem for you). I have crated a Custom Post Type named (example:) "Cuspost" and I have Custom Taxonomy inside Cuspost named "Custax". Then I have taxonomies: "A Custax" and "B Custax" inside Custax.

我想做的就是例如检查Custax的值。与 has_custax（'a-custax'）（类似于 has_category（'a-category'））;

What I want to do is just want to check the value of the Custax, for example with has_custax('a-custax') (similar to has_category('a-category'));

接下来的用途是

<?php if (has_custax('a-custax')) {
    echo 'do something A';
} else {
    echo 'do something B';
}

供您参考，我已阅读此内容（ http://wordpress.org/support/topic/custom-taxonomies-conditional-tags#post -1110167 ），它并不起作用。

For your reference, I've read this (http://wordpress.org/support/topic/custom-taxonomies-conditional-tags#post-1110167) and it aint work.

感谢帮助。

推荐答案

在 functions.php 上解决此功能，类似于Justin Tadlock解决方案

Solve with this function on functions.php similar to Justin Tadlock solutions

<?php function has_custax( $custax, $_post = null ) {
    if ( empty( $custax ) )
        return false;
    if ( $_post )
        $_post = get_post( $_post );
    else
        $_post =& $GLOBALS['post'];
    if ( !$_post )
        return false;
    $r = is_object_in_term( $_post->ID, 'custax', $custax );
    if ( is_wp_error( $r ) )
        return false;
    return $r;
}
?>

这是条件标记。可以在循环内/循环外使用：

And this is the conditional tag. Can be used in/outside the loop:

<?php if ( has_custax( 'a-custax', $post->ID ) ) {
      echo 'do something A';
} else { echo 'do something B'; }; ?>
