wordpress:previous_post_link()/next_post_link() 占位符 [英] wordpress: previous_post_link() / next_post_link() placeholder

问题描述

我在使用 previous_post_link() 和 next_post_link() 功能时遇到问题.当没有以前的帖子时，函数 previous_post_link() 不显示链接，对于 next_post_link() 和最后一个帖子也是如此.我想要一个占位符图像，以便设计保持一致.

I am having trouble with the previous_post_link() and next_post_link() functionality. When there is no previous post, the function previous_post_link() does not display a link, likewise for the next_post_link() and the last post. I would like to have a placeholder image so that the design stays consistent.

目前我有指向左和右的绿色箭头的图像，如果没有更多的帖子可以返回，我想放置一个灰色箭头的图像.

Currently I have images of green arrows pointing left and right, I would like to place an image of a grey arrow if there are no more posts to go back to.

有没有办法使用 next_post_link()/previous_post_link() 函数但不删除链接.

Is there a way to use the next_post_link()/previous_post_link() functions but not have the link removed.

我也想知道有没有办法让链接循环，这样如果你来到最近的帖子，下一个帖子的链接就会把你带回到第一个帖子.

I also wonder if there is a way for the links to cycle, so that if you come to the most recent post, the next post link would bring you back to the first post.

这是基于silent's"建议(接受的答案)使用 get_adjacent_post() 的代码:

Here is the code, based on "silent's" advice (accepted answer) to use get_adjacent_post():

<?php 
    if(get_adjacent_post(false, '', true)) { 
        previous_post_link('%link','<img src="larr.gif"/>'); 
    }
    else { 
        echo '<img src="larr2.gif"/>'; 
    }; 

    if(get_adjacent_post(false, '', false)) { 
        next_post_link('%link','<img src="rarr.gif"/>'); 
    }
    else { 
        echo '<img src="rarr2.gif">'; 
    }; 
?>

推荐答案

我自己从来没有尝试过.但是，您可以参考这篇文章.它使用 get_adjacent_post().

I never try this myself. However, you may refer to this post. It uses get_adjacent_post().
