在foreach循环中输出Echo计数 - Echo count out within foreach loop

Echo count out within foreach loop

本文关键字：Echo 计数输出 foreach 循环 | 更新日期: 2023-09-27

如何回显foreach循环中的计数?我想改变下面的div的类它是menu-button-1, menu-button-2等等等等:

    <?php 
$pages = get_children(array('orderby' => 'menu_order', 'order' => 'asc'));
foreach($pages as $post) {
setup_postdata($post);
$fields = get_fields();
?>
    <div class="menu-button-(insert counter here)">
        <a href="<?php echo get_page_link( $post->ID ); ?>"><?php echo $post->post_title; ?></a>
    </div>
<?php
}
wp_reset_query();
?>

我想让它输出像这样的东西- <div class="menu-button-1">然后<div class="menu-button-2">等等每次它通过循环

    <?php 
$pages = get_children(array('orderby' => 'menu_order', 'order' => 'asc'));
$i=1;
foreach($pages as $post) {
setup_postdata($post);
$fields = get_fields();
?>
    <div class="menu-button-$i">
        <a href="<?php echo get_page_link( $post->ID ); ?>"><?php echo $post->post_title; ?></a>
    </div>
<?php
$i++;
}
wp_reset_query();
?>
