如何在分类前台获取自定义字段值

我在自定义模块中添加了一个名为custom_image 使用add_action( \'taxonomy_name_add_form_fields). 并且它成功地添加和保存了分类法。

但如何在我的自定义模板中获得它？

EDIT : 使用此文章https://gist.github.com/mathetos/1eea92f71934442671a7 代码如下：

<?php

/* Add Image Upload to Series Taxonomy */

// Add Upload fields to "Add New Taxonomy" form
function add_series_image_field() {
    // this will add the custom meta field to the add new term page
    ?>
    <div class="form-field">
        <label for="series_image"><?php _e( \'Series Image:\', \'journey\' ); ?></label>
        <input type="text" name="series_image[image]" id="series_image[image]" class="series-image" value="<?php echo $seriesimage; ?>">
        <input class="upload_image_button button" name="_add_series_image" id="_add_series_image" type="button" value="Select/Upload Image" />
        <script>
            jQuery(document).ready(function() {
                jQuery(\'#_add_series_image\').click(function() {
                    wp.media.editor.send.attachment = function(props, attachment) {
                        jQuery(\'.series-image\').val(attachment.url);
                    }
                    wp.media.editor.open(this);
                    return false;
                });

// Add Upload fields to "Edit Taxonomy" form
function journey_series_edit_meta_field($term) {

    // put the term ID into a variable
    $t_id = $term->term_id;

    // retrieve the existing value(s) for this meta field. This returns an array
    $term_meta = get_option( "weekend-series_$t_id" ); ?>

    <tr class="form-field">

如何获取术语的IDget_queried_object(), 返回查询的对象。如果你在分类学中。php模板或标记。php或类别。php这将是当前的术语对象：

WP_Term Object
(
    [term_id] => 20
    [name] => Schlagwort
    [slug] => schlagwort
    [term_group] => 0
    [term_taxonomy_id] => 20
    [taxonomy] => post_tag
    [description] => 
    [parent] => 0
    [count] => 0
    [filter] => raw
)

因此，要获取这些模板中的术语ID，可以执行以下操作：

$current_object = get_queried_object();
$term_id = $current_object->term_id;

如何获取某个帖子附带的术语ID

get_the_terms()

$terms = get_the_terms( get_the_ID(), \'post_tag\' ); foreach ( $terms as $term ) { $term_id = $term->term_id; /* Do something with the $term_id */ }

post_tag

如何获取分类法中所有术语的术语ID最后，假设您有一个分类法，并且希望将所有术语的术语ID附加到此分类法中get_terms() 是你的朋友。

$terms = get_terms( \'post_tag\' );
foreach ( $terms as $term ) {
    $term_id = $term->term_id;
    /* Do something with the $term_id */
}

Custom Taxonomy Page

我正在尝试创建一个显示特定类别的所有子类别的页面。所以在上下文中，我有一个标题为“目的地”的父类别。我希望能够点击目的地，并被引导到一个页面，显示子类别或国家的列表。下面是我试图实现的一个示例，减去顶部的地图-https://www.vagabrothers.com/destinations. 在理想情况下，类别页面的布局将与此页面相同。你可以从上面的例子中看出我的意思。它会使网站上的导航像这样：目的地>国家>个人帖子。我正在使用CPT UI，设置了一个名为“目的地”的自定义帖子类型和类别，然
