我目前正在使用此代码仅显示正在查看的当前类别的子术语 -
<?php
//first get the current term
$current_term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
//then set the args for wp_dropdown_categories
$args = array(
'child_of' => $current_term->term_id,
'taxonomy' => $current_term->taxonomy,
'hide_empty' => 0,
'hierarchical' => true,
'depth' => 2,
'title_li' => '',
'show_option_all' => All,
'hide_if_empty' => true
);
wp_dropdown_categories( $args );
?>
我需要能够向 's 和开头添加值和类。我怎样才能修改上面的代码来做到这一点?
我不确定,但我想我已经接近了。-
<?php
function get_terms_dropdown($taxonomies, $args){
//first get the current term
$current_term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
$args = array(
'child_of' => $current_term->term_id,
'taxonomy' => $current_term->taxonomy,
'hide_empty' => 0,
'hierarchical' => true,
'depth' => 2,
'title_li' => '',
'show_option_all' => All,
'hide_if_empty' => true
);
$output ="<select name='".$term_slug."'><option selected='".$selected."' value='".$emptyvalue."'>Select a Category</option>'";
foreach($current_term as $term){
$output .="<option name='".$term_slug."' value='".$link."'>".$term_name."</option>";
}
$output .="</select>";
return $output;
}
echo get_terms_dropdown($taxonomies, $args);
?>
问题是下拉菜单没有显示任何类别/术语,我错过了什么?
