我在用 get_posts 和 get_comments 要在页面上构建几个循环，在该页面上我遇到了一些分页问题。
我有每个页面选项的全局帖子 （设置>阅读） 调成 10, ，这似乎改变了问题。到目前为止，我可以轻松地到达 第2页 - http://dev.ashfame.com/author/ashfame/page/2/, ， 但 第3页 返回a 404.
如果我降低了全球价值，我将拥有更多的分页页，但不是全部（比应该有多少个）。
更新： 我只是尝试将自定义设置设置为2（也是全局一个），而WordPress应该分页直到 第4页 （我有 7 要显示的项目），但现在确实如此 第5和6页 给予 404. 。为什么？我现在如何对此问题进行故障排除？
进步： @t31OS帮助我确定了该页面设置分页的页面上的WP默认查询。现在，我可以想到一种杀死该页面上默认WP查询的方法（但是如何？），然后我将如何进一步分页。 作者.php 页？还是还有其他方法？
当前代码：
<?php
$author_details = $wp_query->get_queried_object();
// Posts Per Page option
// $ppp = get_option('posts_per_page');
$ppp = 1; //custom setting, if you want to obey the global setting here, comment this line and uncomment the above line
if (!is_paged()) {
$custom_offset = 0;
} else {
$custom_offset = $ppp*($paged-1);
}
echo '<h1>Author ID : '.$author_details->ID.', Page : '.$paged.', Custom Offset : '.$custom_offset.'</h1>';
?>
<h2>Articles</h2>
<?php
$args = array(
'numberposts' => $ppp,
'offset' => $custom_offset,
'category' => 7,
'author' => $author_details->ID
);
$posts_data = get_posts( $args );
// print_r($posts_data);
if ( count( $posts_data ) > 0 ) {
echo '<ul>';
foreach ( $posts_data as $post ) {
echo '<li><a href="'.get_permalink( $post->ID ).'">'.$post->post_title.'</a></li>';
}
echo '</ul>';
} else {
echo '<p>No articles by this user</p>';
}
?>
<h2>Journals</h2>
<?php
$args = array(
'numberposts' => $ppp,

$posts_data = get_posts( $args );
// print_r($posts_data);
if ( count( $posts_data ) > 0 ) {
echo '<ul>';
foreach ( $posts_data as $post ) {
echo '<li><a href="'.get_permalink( $post->ID ).'">'.$post->post_title.'</a></li>';
}
echo '</ul>';
} else {
echo '<p>No journals by this user</p>';
}
?>
<h2>Questions</h2>
<?php
$args = array(
'numberposts' => $ppp,
'offset' => $custom_offset,
'category' => 3, // parent category ID is enough
'author' => $author_details->ID
);
$posts_data = get_posts( $args );
// print_r($posts_data);
if ( count( $posts_data ) > 0 ) {
echo '<ul>';
foreach ( $posts_data as $post ) {
$category_array = get_the_category( $post->ID );
$category_name = $category_array[0]->name;
$category_permalink = get_category_link( $category_array[0]->term_id );
echo '<li><a href="'.get_permalink( $post->ID ).'">'.$post->post_title.'</a>
<br />In: <a href="'.$category_permalink.'">'.$category_name.'</a><br />'.get_comments_number( $post->ID ).' Answers</li>';
}
echo '</ul>';
} else {
echo '<p>No questions by this user</p>';
}

<h2>Answers</h2>
<?php
$args = array(

);
$answers_list = get_comments( $args );
// print_r($answers_list);
if ( count( $answers_list ) > 0 ) {
$date_format = get_option( 'date_format' );
echo '<ul>';
foreach ( $answers_list as $answer ) {
echo '<li>Answer: '.substr( $answer->comment_content, 0, 20 ).'..<br />'.date( $date_format, strtotime( $answer->comment_date ) ).'<br />Question: <a href="'.get_permalink( $answer->comment_post_ID ).'">'.get_the_title( $answer->comment_post_ID ).'</a></li>';

解决方案
T31OS说： 有关以前的代码和评论，请参见编辑历史记录
使用ajax打开查询
我整理了一些代码，可以使用Ajax通过简单的PREV/下一个导航通过AJAX获取您的帖子和评论。
1) 替换您在您中发布的所有代码 作者.php 以下..
<?php $cat_settings = array( 'Articles' => 7, 'Journals' => 6, 'Questions' => 3 ); ?>
<?php do_action( 'author_ajax_catposts', $cat_settings ); ?>
2) 在主题目录中创建一个JavaScript文件称为 authorposts.js 并将以下代码放入该文件中。
jQuery(document).ready( function($) {
if( 'undefined' == typeof( aacVars ) )
return;
$('.aacnav').click(function() {
var r = $( $(this).attr('href') );
var a = $( $(this).attr('href') + '-ap' );
var c = this.className.split(' ');
if(
'undefined' == typeof( c ) ||
'undefined' == typeof( r ) ||
'undefined' == typeof( a )
)
return false;
var d = {
action: aacVars.posts_action,
_ajax_nonce: aacVars.nonce,
author: aacVars.author,
category: $(this).attr('href')
};
p = parseInt( a.text() );
c = c.pop();
switch( c ) {
case 'aacnext':
if( r.children('p.nomore').length )
return false;
d.page = p + 1;
break;
case 'aacprev':
if( p < 2 )
return false;
d.page = p - 1;
break;
default:
return false;
}
$.post( aacVars.ajaxpth, d, function( res ) {
if( '-1' == res ) {
alert( 'auth failed' );
return false;
}
$( r ).html( res );
$( a ).text( d.page );
});
return false;
});
$('.aacnavc').click(function() {
var r = $( '#aac-comments' );
var n = $( '#aac-comments-ap' );
var l = $(this).attr('href');
if(
'undefined' == typeof( n ) ||
'undefined' == typeof( r )
)
return false;
var d = {
action: aacVars.comments_action,
_ajax_nonce: aacVars.nonce,
author: aacVars.author
};
p = parseInt( n.text() );
switch( l ) {
case '#next':
if( r.children('p.nomore').length )
return false;
d.page = p + 1;
break;
case '#prev':
if( p < 2 )
return false;
d.page = p - 1;
break;
default:
return false;
}
$.post( aacVars.ajaxpth, d, function( res ) {
if( '-1' == res ) {
alert( 'auth failed' );
return false;
}
r.html( res );
$( n ).text( d.page );
});
});
});
3) 将以下代码复制到您的主题中 functions.php 文件。
