[英]Custom field value inside WP_Query
I want a WP_Query, that displays all the posts, that have the same custom field value as the display post. 我想要一个WP_Query,它显示所有与显示帖子具有相同自定义字段值的帖子。
This is my Code: 这是我的代码:
function show_other_posts() {
//Get the current custom field value
if( get_field('desktop_cat') ){
$redirect_value = the_field('desktop_cat');
//Echo the current custom field value for debugging
echo $redirect_value;
//Query Posts with same value
$redirect_args = array(
'posts_per_page' => -1,
'post_type' => 'post',
'meta_query' => array(
array(
'key' => 'desktop_cat',
'value' => $redirect_value,
'compare' => '='
)
)
);
//Display the Post Titles
$the_query = new WP_Query ( $redirect_args );
if( $the_query->have_posts() ): while( $the_query->have_posts() ) : $the_query->the_post();
the_title();
endwhile;endif;
wp_reset_query();
};
};
The Problem must be 'value' => $redirect_value,
because when i enter a value manually it works well. 问题必须是
'value' => $redirect_value,
因为当我手动输入一个值时,它会很好地工作。 There must be a problem with that variable. 该变量一定有问题。
Any ideas? 有任何想法吗?
Thank you so much 非常感谢
the_field()
echoes the field value. the_field()
回显字段值。 You should use get_field()
instead (which returns, not echoes the field value): 您应该改用
get_field()
(它返回而不是回显字段值):
$redirect_value = get_field('desktop_cat');
