Question

我要做的是创建一个wp_query，以便结果只是标题的首字母。

这就是我展示的方式。超链接字母＆amp;数字..

<div class="align_Center">

<?php $args = array(
"0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","ALL"           ); ?>

<?php

for($x = 0; $x < 37; $x++) { ?>

<span style="color: #777;">&nbsp;|&nbsp;</span>

<a href="../page-title-<?php echo $args[$x]; ?>" class="movie_lists"><?php echo $args[$x]; ?></a>

<?php } ?>

<span style="color: #777;">&nbsp;|</span>

</div>

这是我的测试页面..

<div class="col-md-6">      

<!-- ############################################## -->
<!-- ############### PAGE TITLE T ################# -->
<!-- ############################################## -->

<p class="f_header">PAGE TITLE T</p>

<?php

    global $wpdb;
    $first_char = 'T';
    $postids = $wpdb->get_col($wpdb->prepare("
    SELECT      ID
    FROM        $wpdb->posts
    WHERE       SUBSTR($wpdb->posts.post_title,1,1) = %s
    ORDER BY    $wpdb->posts.post_title",$first_char)); 

if ($postids) {
$args = array(

        'post__in'          => $postids,
        'post_type'         => 'post',
        'post_status'       => 'publish',
        'posts_per_page'    => -1,
        'caller_get_posts'  => 1

    );

    $query = new WP_Query( $args );

    if ($query->have_posts()) {

?>

<table width="100%"><!-- #### TABLE #### -->

    <?php

        while ($query->have_posts()) {

            $query->the_post();

    ?>

    <tr style="border-bottom: thin solid #111;">

        <td class="movie_genre">    

            <a href="<?php the_permalink() ?>"><?php the_title(); ?></a>

        </td>

    </tr>

    <?php }; ?>

</table><!-- #### / TABLE #### -->

<?php }; wp_reset_postdata(); }; ?>

测试页面目前在根主题目录中保存为page-title-t，目前它没有提供任何数据，所以我有点困惑。

提供的代码是正确的，包含以下一般注释：

您说明了您正在列出网页，但您的查询指出'post_type' => 'post'。 post_type参数同时接受字符串或数组，因此您可以选择'post_type' => 'page'或'post_type' => array('post','page')
确保您的数据库归类是不区分大小写，（应以_ci结尾，例如utf8_general_ci ）否则您应该处理小的大写字母查询（t和T）
附加说明 - caller_get_posts中的$args应移至{em> WordPress 版本大于 3.1.0 <的ignore_sticky_posts / LI>

wp_query标题的初始版本
