Question

我对php和api调用很陌生，我很难理解如何在列表到达＆＃39; n＆＃39;水平？我理解简单的分解标记，如下所示：Break and Create new after 10 values from foreach loop php

但我对我的实现有点困惑，因为调用我的api需要两对foreach嵌套。

这就是我现在所得到的：

这就是我应该期待的：

<ul class="menu" id="nav">
  <li>Shop By Categories</li>
  <?php 
    $resultListAllCategories = get_decoded_info ( $SERVER_URL, $PORT, 'tos-product/user/category/listAll', $fields );
    foreach ( $resultListAllCategories as $key => $eachDetail ) {
        foreach ( $eachDetail as $key => $eachData ) {
            if(! isset($eachData['parentCategoryId'])){
                $x = $eachData['catId'];?>
    <li><a href="#"><?php echo $eachData['catName'];?></a>
      <div class="megadrop">
        <div class="col">
<?php 
    $break_after = 2;

    $counter = 0;

    foreach ( $resultListAllCategories as $key => $eachDetail ) {
        if ($counter % $break_after == 0) {
            echo '<ul>';
        }
        foreach ( $eachDetail as $key => $eachData ) {
            if(isset($eachData['parentCategoryId'])){
                $y = $eachData['parentCategoryId'];
                if($y == $x) { 
                    echo '<li>'.$eachData['catName'].'</li>';
                    if ($counter % $break_after == ($break_after-1)) {
                        echo '</ul>';
                    }
                    ++$counter;
                }
             }
         }
    }

?>
        </div>
    </div>
    </li>
    <?php }}}?>
  </ul>

$ resultsListAllCategories

Answer 1

这对我有用

<ul class="menu" id="nav">
  <li>Shop By Categories</li>
  <?php 
    if ($_SESSION["loginSuccess"])
        $sessionId = $_SESSION["sessionId"];
    else
        $sessionId = $non_login_user;

    $fields = array (
            'projectId' => $PROJECT_ID,
            'sessionId' => $sessionId
    );
    $resultListAllCategories = get_decoded_info ( $SERVER_URL, $PORT, 'tos-product/user/category/listAll', $fields );

    foreach ( $resultListAllCategories as $key => $eachDetail ) {
        foreach ( $eachDetail as $key => $eachData ) {
            if(! isset($eachData['parentCategoryId'])){
                $x = $eachData['catId'];?>
    <li><a href="#"><?php echo $eachData['catName'];?></a>
      <div class="megadrop">
        <div class="col">
         <?php 
          $cur = 0;
            foreach ( $resultListAllCategories as $key => $eachDetail ) {
                foreach ( $eachDetail as $key => $eachData ) {
                    if(isset($eachData['parentCategoryId'])){
                        $y = $eachData['parentCategoryId'];

            if($y == $x) { 
                 if($cur == 0) {
                    echo '<ul>';
                }
                echo '<li>'.$eachData['catName'].'</li>';
            if($cur == 1) {
                echo '</ul>';
                $cur = 0;
            }
            else {
                $cur++;
            } }}
            }}
            ?>
        </div>
    </div>
    </li>
   <?php }}}?>
</ul>

2 foreach。因为＆＃39; n＆＃39;水平，打破新的ul
