Question

我使用以下代码来显示特定联赛的总年数，但每年显示1个。

例如，西班牙语Primera Division有三年但显示1,1,1而不是3。

我使用了count($object);和sizeof($object);，但没有得到理想的结果。

这是我的代码：

<div class=" reds clearfix"; style="width: 50%;">
    <ul id="test">
        <!-- the loop -->
        <?php while ( $fixture_query->have_posts() ) : $fixture_query->the_post(); ?>
            <?php
            $champion_team = get_post_meta( get_the_ID(), 'football_league_team_name', true );
            $terms_competition = get_the_terms( get_the_ID(), 'competition' );
            $terms_session = get_the_terms( get_the_ID(), 'session' ); ?>

            <?php foreach ($terms_session as $object) {?>
                <li style="float: left; margin-right: 5px;"> <?php echo  $object->name; ?></li>
                <?php
                //echo count($object); // output 2
                echo sizeof($object);
                // echo count($object->name); 
                ?>
            <?php } ?>

        <?php endwhile; ?>
        <!-- end of the loop -->
        <?php wp_reset_postdata(); ?>
    </ul>
</div>

Answer 1

<?php
echo count($terms_session);//this give all count of elements
foreach ($terms_session as $object) { ?>
    <li style="float: left; margin-right: 5px;"> <?php echo $object->name; ?></li>
    <?php
    //echo count($object); // output 2
    echo sizeof($object);
    // echo count($object->name); 
    ?>
<?php }
?>

Answer 2

我假设您要显示foreach循环内的会话总数。

根据您的代码，您可以将会话总数计算为

$total_sessions = count($terms_session);

现在您可以在foreach循环中轻松使用此变量

<?php
    foreach ($terms_session as $object) {?>
        <li style="float: left; margin-right: 5px;"> <?php echo  $object->name; ?></li>
        <?php 
        echo $total_sessions;
        ?>
<?php }
?>

以下是包含更改的完整代码，请参阅添加内容的注释。

<div class=" reds clearfix"; style="width: 50%;">
  <ul id="test">

    <!-- the loop -->
    <?php while ( $fixture_query->have_posts() ) : $fixture_query->the_post(); ?>
      <?php
      $champion_team = get_post_meta( get_the_ID(), 'football_league_team_name', true );
      $terms_competition = get_the_terms( get_the_ID(), 'competition' );
      $terms_session = get_the_terms( get_the_ID(), 'session' ); 
      // Calculate the total number of sessions
      $total_sessions = count($terms_session);
      ?>
      <?php
      foreach ($terms_session as $object) {?>
      <li style="float: left; margin-right: 5px;"> <?php echo  $object->name; ?></li>
      <?php 
        // Display the total number of sessions
        echo $total_sessions;
      ?>
      <?php }
      ?>

    <?php endwhile; ?>
    <!-- end of the loop -->

    <?php wp_reset_postdata(); ?>
  </ul>


</div>
