我的 WordPress 帖子循环有问题。我想分解帖子循环,在帖子中添加一些 HTML div 标签。例如,我试图.wrap在第一次发布后在帖子周围添加一个 div。因为它是为了包装帖子,所以它应该只有一次。

问题是.wrapdiv 由于循环而被重复。如何打破循环,.wrap只添加一次 div 然后继续循环?

这是我的代码:

while ($wp_query->have_posts()) :

    $wp_query->the_post(); 
    if($wp_query->current_post <= 1){ ?>
        <div class="x">
        .. post 1
        </div>
    <?php }
    if($wp_query->current_post > 1){ ?>
        <div class="wrap"> <!-- should be only once -->
            <div class="y">
            .. post 2
            </div>

            <div class="y">
            .. post 3
            </div>
        </div><!-- should be only once -->
    <?php } ?>

endwhile;

尝试这个

<?php
while ($wp_query->have_posts()) :
    $wp_query->the_post(); 
    if($wp_query->current_post <= 1){ ?>
        <div class="x">
        .. post 1
        </div>
        <div class="wrap"> <!-- should be only once -->
    <?php 
    $is_wrapped = 1;
    }
    if($wp_query->current_post > 1){ ?>
        <div class="y">
          .. post 2, then post 3, ...
        </div>
    <?php } 
endwhile;?>
<?php if (!empty($is_wrapped)){ ?>
        </div><!-- should be only once -->
<?php } ?>

您可以只使用迭代器索引,如下所示:

$i = 0;
while (...) {
    if ($i == 1) {
       // actions you need to do only once
    }

    ...
    $i++
}

<div class="x">

while ($wp_query->have_posts()) :
    $wp_query->the_post();
    <--print post-->
    if($wp_query->current_post <= 1){
        </div><div class="y">
    }
endwhile;

</div>

<div class="x" />如果没有帖子,您将获得一个空白,如果<div class="y" />只有一个帖子,您将获得一个空白。但在你的情况下这可能是可行的......


编辑:示例

<?php
$wp_query = new WPDummy; 

echo '<div class="x">';    
while ($wp_query->have_posts()) :
    $wp_query->the_post();
    $wp_query->the_content();
    if($wp_query->current_post <= 1){
        echo '</div>', "\n",'<div class="y">';
    }
endwhile;
echo '</div>';

// boilerplate
class WPDummy {
    public $current = null;
    public $current_post = 0;
    public function __construct() {
        $this->posts = array( array('content'=>'A'),array('content'=>'B'),array('content'=>'C'),array('content'=>'D') );
    }

    public function have_posts() {
        return false!=current($this->posts);
    }

    public function the_post() {
        $this->current_post+=1;
        $this->current = current($this->posts);
        next($this->posts);
    }

    public function the_content() {
        echo '<span class="content">', $this->current['content'], '</span>';
    }
}

<div class="x"><span class="content">A</span></div>
<div class="y"><span class="content">B</span><span class="content">C</span><span class="content">D</span></div>
