<div class="puffar">

     $all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

     $i = 0; 
     //Build custom items

嗨堆垛機！

我需要一些關於如何包裝循環元素的PHP幫助。我想包裝2個元素在<div class="row">.所以基本上<row> <item> <item> </row>

我已經嘗試了一些模數，你可以看到，一些if語句仍然存在。我設置我爲0，並試圖把<div class="row"> 1％2 = 0時，但發現如何正確關閉標籤沒有解決方案（應在第二項後關閉） 任何機會，你可以幫助我作爲一個新手PHP黑客？

編輯：

<div class="puffar"> 
     <?php 
     //Set up the objects needed 
     $my_wp_query = new WP_Query(); 
     $all_wp_pages = $my_wp_query->query(array('post_type' => 'page')); 

     //Get children 
     $children = ($post->post_parent) ? get_page_children($post->post_parent, $all_wp_pages) : get_page_children($post->ID, $all_wp_pages); 

     $i = 0; 
     //Build custom items 
     echo "<div class='row'>"; 
     foreach($children as $child){ 
     ?> 

<div class="col-sm-6"> 
    <div class="puff"> 
     <div class="puff-image-holder"> 
      <?php echo get_the_post_thumbnail($child->ID, 'full'); ?> 
     </div> 
     <fieldset class="linedHeadline hlmedium"> 
      <legend><?php echo get_the_title($child->ID); ?></legend> 
     </fieldset> 
     <?php echo get_field("puff_introtext", $child->ID); ?> 
     <?php 
     $values = get_field('puff_lanktext', $child->ID); 
     if (get_field("popup_eller_lank", $child->ID) == "popup") { 
     ?> 
     <fieldset class="linedHeadline hlmedium"> 
      <legend><a class ="linktopage open-popup" href="<?php echo get_page_link($child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a></legend>

     <?php 
     $i++; 
     if ($i % 2 == 0) { 
      echo "</div><div class='row'>"; 
     } 
     } else { } 
     ?> 
    </div> 
</div> 

<?php } ?> 
</div> 
</div> 

這隻包我所有的循環項目，我想在div類=行只包每2項

Answer 1

試試這個

$i = 1; 
     //Build custom items 
     foreach($children as $child){ 
     if($i>2){ 
     $i =1; 
     } 

     if ($i==2) { 
      //close row 
     } 
     $i++; 
    } 

Answer 2

您應該使用一個for循環而不是foreach循環如下：

for($i = 0; $i < count($children); $i+=2) { 
    $child1 = $children[$i]; 
    $child2 = $children[$i+1]; 
    // print both 
} 

如果您可能有奇數個孩子，您必須在打印前檢查它是否爲$i+1 < count($children)。

Answer 3

你幾乎沒有：

//Build custom items 
    echo "<row>"; 
    $i = 0; 
    foreach($children as $child) { 

     echo "item "; 

     $i++; 
     if ($i % 2 == 0 && $i != count($children)) { 
      echo "</row><row>"; 
     } 

    } 
    echo "</row>" 

Answer 4

或者這樣：

<?php 
$i=0; 
foreach($children as $child){ 
    ++$i; 
    if($i==1){ 
     echo "<row>"; 
     echo "<item>$child</item>"; 
    } 
    if($i==2){ 
     echo "<item>$child</item>"; 
     echo "</row>" 
     $i=0; 
    } 
}
