Question

在互联网上漂浮是一段PHP代码，旨在显示WordPress中最近更新的帖子/页面。在向专家提交请求之后，我很快就得到了我需要的原始代码。

然而，原始的PHP代码仍然不能用于我的WordPress安装。经过一些调整和许多额外的花里胡哨之后，我设法拼凑了仅显示最近更新的帖子所需的代码。

此时我请求帮助仅显示特定类别的帖子。是否可以仅显示特定类别的帖子？你能帮忙吗？

这是当前的代码：

<div class="statistics">
<?php
$today = current_time('mysql', 1);
$howMany = 10; //Number of posts you want to display
if ($recentposts = $wpdb->get_results("SELECT ID, post_title, post_modified FROM $wpdb->posts    WHERE post_status = 'publish' AND post_type = 'post' AND post_name NOT LIKE  '%revision%' AND post_name NOT LIKE '%autosave%' AND post_modified_gmt < '$today' ORDER BY post_modified_gmt DESC LIMIT $howMany")) :
?>
<h2><?php _e('ULTIME SERIE TV AGGIORNATE'); ?></h2>         
<ul>
<?php
foreach($recentposts as $post) {
if ($post->post_title == '') {
$post->post_title = sprintf(__('Post #%s'), $post->ID);
}
/* If no post title exists one will be assigned to it. */
echo "<li><a href='".get_permalink($post->ID)."'>";
echo mysql2date('d/m/Y', $post->post_modified); 
echo "&nbsp;-&nbsp;";
echo $post->post_title;
echo '</a></li>';
}
?>
</ul>
<?php endif; ?>
</div>

该表是存储在 wp_term_taxonomy 中的类别，该方法用于存储特定类别数据库下的项目及其 ID （ term_taxonomy_id ）这是一张图片：

TABLE picture

在插件（recently-updated-posts）中我发现了这个功能，但我不知道怎么把它放在我的代码中......

if ($options['excludeCategory']) {
$select .= ", GROUP_CONCAT(`tt`.`term_id`) AS `terms`";
$from   .= " LEFT JOIN `{$wpdb->term_relationships}` AS `tr` ON `tr`.`object_id` = `p`.`ID`"
                     . " LEFT JOIN `{$wpdb->term_taxonomy}` AS `tt` ON `tt`.`term_taxonomy_id` =   `tr`.`term_taxonomy_id`";
 $where  .= " AND `tt`.`taxonomy` = 'category'"
 . " AND `tt`.`term_id` NOT IN ({$options['excludeCategory']})";
 $group  = "GROUP BY `ID`";
 }

我会使用wp_get_recent_posts并传入类别的参数。

<ul>
<?php
$args = array( 'category' => '5' );
$recent_posts = wp_get_recent_posts( $args );
foreach( $recent_posts as $post ){
if ($post["post_title"] == '') {
$post["post_title"] = sprintf(__('Post #%s'), $post["ID"]);
}
?>
<li><a href='<?php echo get_permalink($post["ID"]) ?>'>
<?php echo mysql2date('d/m/Y', $post["post_modified"])?>
&nbsp;-&nbsp;
<?php echo $post["post_title"]?>
</a></li>
}
?>
</ul>

最终代码：

<div class="update">
<?php
$today = current_time('mysql', 1);
if ($recentposts = $wpdb->get_results("SELECT ID, post_title, post_modified FROM $wpdb->posts    WHERE post_status = 'publish' AND post_type = 'post' AND post_name NOT LIKE  '%revision%' AND post_name NOT LIKE '%autosave%' AND post_modified_gmt < '$today' ORDER BY post_modified_gmt")) :
?>
<h2><?php _e('GLI ULTIMI EPISODI AGGIUNTI'); ?></h2>        
<ul>
<?php $args = array('category' => '30', 'orderby'  => 'modified', 'post_status' => 'publish',   'posts_per_page' => 11);
$recent_posts = wp_get_recent_posts($args);
foreach ($recent_posts as $post) {
if ($post["post_title"] == ''){ $post["post_title"] = sprintf(__('Post #%s'), $post["ID"]);
}
?>
<li><?php echo mysql2date('d/m/Y', $post["post_modified"]) ?>
&nbsp;-&nbsp;
<a href='<?php echo get_permalink($post["ID"]) ?>'>
<?php echo $post["post_title"] ?>
</a></li> <?php } ?>
</ul>
</div>
<?php endif; ?>

此代码是获取最近更新的帖子和页面的另一种方法。

<?php 

$today  = current_time('mysql', 1);
$number = 5; // number of posts

if($recentposts = $wpdb->get_results("SELECT ID, post_title FROM $wpdb->posts WHERE post_status = 'publish' AND post_modified_gmt < '$today' ORDER BY post_modified_gmt DESC LIMIT $number")):

?>

<h2><?php _e("Recently Updated"); ?></h2>
<ul>
<?php

foreach($recentposts as $post) {

    if($post->post_title == '') $post->post_title = sprintf(__('Post #%s'), $post->ID);
    echo '<li><a href="'.get_permalink($post->ID).'">'.the_title().'</a></li>';

} ?>
</ul>

<?php endif; ?>
