Question

我遇到了WordPress帖子循环的问题。我想打破post循环，在帖子中添加一些HTML div标签。例如，我在第一篇文章后尝试在帖子周围添加div .wrap。由于要包装帖子，所以它应该只有一次。

问题是由于循环，.wrap div正在重复。如何打破循环，只添加.wrap div一次，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;

Answer 1

试试这个

<?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 } ?>

Answer 2

您可以使用迭代器索引，如下所示：

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

    ...
    $i++
}

Answer 3

<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>

如果没有帖子，您将获得空<div class="x" />，如果只有一个帖子，则会显示空<div class="y" />。但在你的情况下可能是可行的......

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>';
    }
}

打印

<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>

PHP：中断循环，然后继续？
