PHP 循环 - 如何显示具有自己样式和 div 顺序的 2 个项目，然后显示下一个具有反向 div 顺序和类的 2 个项目

标签 php mysql count

我需要以相反的顺序和不同的 css 类显示多个项目(每个项目包含两个 div)。前两项需要有 IMAGE-CONTENT div 的顺序，然后接下来的两项需要有 CONTENT - IMAGE div 的顺序。？

我不知道该怎么办。如何使用计数/模数？

任何人都可以为此提供简单的解决方案吗？ 

   <?php $result_article = $db->query("SELECT * FROM pm_article WHERE     (id_page = ".$page_id." OR home = 1) AND checked = 1 AND (publish_date IS NULL || publish_date <= ".time().") AND (unpublish_date IS NULL || unpublish_date > ".time().") AND lang = ".LANG_ID." ORDER BY rank");
        if($result_article !== false){
            $nb_articles = $db->last_row_count();

            if($nb_articles > 0){ ?>

Screenshoot 1 - This is now and not good

Screenshoot 2 - I would like this

最佳答案

声明$sl=1;在顶部

选择查询中的以下逻辑用于检查条件

if(($sl==1)||($sl==2))
{
   //code for div 1 & 2

    $sl++;   
}
else  //only else is also enough
{

 //code for div 3 & 4
   if($sl==3)
      $sl++;
   else         //$sl=4
     $sl=1;     //reset value of $sl to 1 so the div 1 is shown next
}

会有很多方法..只是我想到的一个简单的逻辑..试试吧

编辑 您的代码中有一些错误 - 你必须放置 else在同一php标记为 if循环关闭。 - $sl=1应该放在顶部..只是在开始时初始化它 - 没有关闭 if <?php if($sl==3 ?> 中的条件制动器 - else 没有分号

            if($result_article !== false){
                $nb_articles = $db->last_row_count();
