显示wordpress的第一个帖子

我才刚开始使用wordpress, 所以对于某些人来说, 我的问题听起来有点简单, 但我找不到如何使它起作用的方法。

我正在wordpress上构建一个博客页面, 我想以不同于其他文章的方式显示第一篇文章, 然后显示一些静态文本, 然后继续第二篇文章的帖子循环。

我的第二个问题是我需要将缩略图以绝对位置放置在div内(现在, 当我调整浏览器大小时, 它正在怪异地缩小)。在我的引导程序原型上, 我将图像放置在div中, 并使用background属性导入了图像。用wordpress替换该行为的最佳方法是什么？

我为此做了一个简单的草图：

我已经搜索了stackoverflow并尝试了一些代码片段, 但是我无法使它们全部正常工作。

顺便说一句, 我正在使用UNDERSTRAP主题作为样板。

这是我的index.php代码：

<?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.
 * Learn more: http://codex.wordpress.org/Template_Hierarchy
 *
 * @package understrap

    exit; // Exit if accessed directly.

你需要忘记默认的WordPress循环。请改用WP_Query类查询你的帖子。

$query = new WP_Query([
   ‘post_type’ => ‘post’, ‘posts_per_page => -1, ]);
 // Get the first post
$firstElement = array_shift($query->posts);
 // Get the other posts exect first element
$otherPosts = $query->posts;

现在, 你需要在模板中循环以创建帖子网格。

此过程是将标签的类别更改为全角。有很多方法可以做到这一点, 但是我发现这很简单。首先, 从content.php中取出标签并将其放在index.php中。这是为了检查并更改article标签内的类。

<div class="site-main" id="main">
<div class="row no-gutters">
<?php if ( have_posts() ) : ?>
    <?php /* Start the Loop */ ?>
    <?php 
    // Required variables
    $post = $posts[0]; $c=0; ?>
    <?php while ( have_posts() ) : the_post(); ?>
        <article class="col p-0 <?php $c++; if($c == 1) { echo 'col-12'; }else{ echo 'col-4'; } ?>" <?php post_class(); ?> id="post-<?php the_ID(); ?>"> 
            <?php
            /*
            * Include the Post-Format-specific template for the content.
            * If you want to override this in a child theme, then include a file
            * called content-___.php (where ___ is the Post Format name) and that will be used instead.
            */
            get_template_part( 'loop-templates/content', get_post_format() );
            ?>
        </article>
    <?php endwhile; ?>
<?php else : ?>
    <?php get_template_part( 'loop-templates/content', 'none' ); ?>
<?php endif; ?>
</div>
