我在这里遇到了一个问题。
我想在 single.php 中显示2个导航按钮,基于分类法(税名: temporada )
现在我谷歌了。我找到了一个简单的代码来显示这个按钮但是,这是按日期的顺序,我喜欢订购,但是自定义字段(自定义字段: numeroepisodio )
这是我的代码:
的functions.php
add_filter( 'get_next_post_join', 'navigate_in_same_taxonomy_join', 20);
add_filter( 'get_previous_post_join', 'navigate_in_same_taxonomy_join', 20 );
function navigate_in_same_taxonomy_join() {
global $wpdb;
return " INNER JOIN $wpdb->term_relationships AS tr ON p.ID = tr.object_id INNER JOIN $wpdb->term_taxonomy tt ON tr. term_taxonomy_id = tt.term_taxonomy_id";
}
add_filter( 'get_next_post_where' , 'navigate_in_same_taxonomy_where' );
add_filter( 'get_previous_post_where' , 'navigate_in_same_taxonomy_where' );
function navigate_in_same_taxonomy_where( $original ) {
global $wpdb, $post;
$where = '';
$taxonomy = 'temporada';
$op = ('get_previous_post_where' == current_filter()) ? '<' : '>';
$where = $wpdb->prepare( "AND tt.taxonomy = %s", $taxonomy );
if ( ! is_object_in_taxonomy( $post->post_type, $taxonomy ) )
return $original ;
$term_array = wp_get_object_terms( $post->ID, $taxonomy, array( 'fields' => 'ids' ) );
$term_array = array_map( 'intval', $term_array );
if ( ! $term_array || is_wp_error( $term_array ) )
return $original ;
$where = " AND tt.term_id IN (" . implode( ',', $term_array ) . ")";
return $wpdb->prepare( "WHERE p.post_date $op %s AND p.post_type = %s AND p.post_status = 'publish' $where", $post-> post_date, $post->post_type );
}
single.php中
<?php if ( get_previous_post() != null ) : ?>
<?php
$singular_nav_previous_text = apply_filters( 'tc_singular_nav_previous_text', _x( '←' , 'Previous post link' , ' customizr' ) );
previous_post_link( '%link' , '<div id="temporadas-dropdown"><i class="fa fa-caret-left"></i> ANTERIOR</div>' );
?>
<?php endif; ?>
<?php if ( get_next_post() != null ) : ?>
<?php
$singular_nav_next_text = apply_filters( 'tc_singular_nav_next_text', _x( '→' , 'Next post link' , 'customizr' ) );
next_post_link( '%link' , '<div id="temporadas-dropdown">SIGUIENTE <i class="fa fa-caret-right"></i></div>' );
?>
<?php endif; ?>
如何显示基于taxonomy = 'temporada'
的按钮并按meta_value = 'numeroepisodio'
排序?
感谢您的时间。
答案 0 :(得分:1)
为什么不使用WP_Query对象,如下所示
$posts = get_posts(array(
'post_type' => 'post',
'posts_per_page' => -1,
'orderby' => 'numeroepisodio',
'order' => 'DESC',
'tax_query' => array(
array(
'taxonomy' => 'temporada'
)
));
if( $posts ): ?>
// Do something here
<? endif;
您可能需要稍微修改它并检查语法..
