Question

由于某些原因，我的ul和lis根据我的代码没有正确匹配。不太清楚为什么。我试过将它移入和移出循环，似乎没有什么是正确的。

<?php
if((isset($categoriesArray)) AND ((!empty($categoriesArray))||($categoriesArray !== NULL)))
{
if(count($categoriesArray) <= 0)
{
    echo "There are no content pages on this site!";
}
else
{
    if (count($categoriesArray) > 0)
    {
        foreach ($categoriesArray as $row)
        {
            echo "<h2>".stripslashes($row['name'])."</h2>";
            echo "<ul>";
            if (count($row['children']) > 0)
            {
                foreach  ($row['children'] as $row2)
                {
                    echo "<li><a href=\"".$row2['link_url']."\">".stripslashes($row2['link_name'])."</a></li>";
                    if (isset($row2['child_pages']) > 0)
                    {
                        echo "<ul>";
                        foreach ($row2['child_pages'] as $row3)
                        {
                            echo "<li><a href=\"".$row3['link_url']."\">".stripslashes($row3['link_name'])."</a></li>";
                        }   
                        echo "<ul>";
                    }
                }
            }
            echo "</ul>";
        }
    }
}
}
else
{
echo "There are no content pages on this site!";
}
?>

Answer 1

1）你有一个错字：

echo "<ul>";
foreach ($row2['child_pages'] as $row3)
{
    echo "<li><a href=\"".$row3['link_url']."\">".stripslashes($row3['link_name'])."</a></li>";
}   
echo "<ul>";

最后一个回应应该是“＆lt; / ul＆gt;”。

2）即使修正了错字，你也有＆lt; ul＆gt;＆lt; li＆gt;＆lt; / li＆gt;＆lt; ul＆gt;＆lt; li＆gt;＆lt; / li＆gt;＆lt; / ul＆gt;＆lt; / ul＆gt;嵌套。内部＆lt; ul＆gt;元素应嵌套在额外的＆lt; li＆gt;中。元素，你可以通过在我复制的行中的第一个和第三个回声中添加li开始和结束标记来完成。

Answer 2

echo "<ul>";
foreach ($row2['child_pages'] as $row3)
{
echo "<li><a href=\"".$row3['link_url']."\">".stripslashes($row3['link_name'])."</a></li>";
}   
echo "<ul>";  <---------------- <ul> -> </ul> this should be a closing ul

与UL和LI对齐
