Question

我在html中获得了这个导航菜单，我需要将其转换为php。我尝试使用php数组和foreach，但我坚持使用子项目。我现在无法弄清楚我该怎么做。有什么想法吗？

这就是我现在所做的。

为父项创建一个数组。

      <div class="containermargins clearfix">
      <nav class="hmenu"data-responsive-menu="true"data-responsive-levels="">
       <div class="responsivemenu collapse-button">
      <div class="container-inner">
        <div class="menuitem ">
          <a data-toggle="collapse"data-target=".hmenu .collapse-button + .navbar-collapse"href="#"onclick="return false;"><span></span></a>
      </div>
  </div>
   </div>
  <div class="navbar-collapse collapse">
  <div class="horizontalmenu  clearfix">
      <div class="container-inner">
          <ul class="menu  nav nav-pills nav-justified">  

`<?php foreach ($navItems as $item) {
echo '<li class="menuitem  submenu-icon-only toplevel-item"><a class="active" href=\"$item[slug]\">$item[title]</a></li>';
  } ?>`

      </ul>
</div>
  </div>

使用foreach并回显它们

<div class="containermargins clearfix">
<nav class="hmenu"data-responsive-menu="true"data-responsive-levels="">
<div class="responsivemenu collapse-button">
  <div class="container-inner">
      <div class="menuitem ">
          <a data-toggle="collapse"data-target=".hmenu .collapse-button + .navbar-collapse"href="#"onclick="return false;"><span></span></a>
          </div>
        </div>
     </div>
    <div class="navbar-collapse collapse">
    <div class="horizontalmenu  clearfix">
      <div class="container-inner">
          <ul class="menu  nav nav-pills nav-justified">
    <li class="menuitem  submenu-icon-only toplevel-item">
    <aclass="active"title=" Direction - Tailor-made  Holidays"href="./home.html">Home</a>
       <div class="menu-popup ">
        <ul class="menu no-margins">

     <li class="menuitem  toplevel-item">
     <a title="Contacts"href="./contacts.html">Contacts</a>
    </ul>
  </div>
  </div>
 </div>
 </nav>

这是我的html导航菜单。

<textarea class='err' rows='1' cols='29' placeholder='Enter error message...' onfocus='this.rows=5; this.cols=40;' onblur='this.rows=1; this.cols=29;var text = document.createElement("textarea"); text.attributes = this.attributes; text.value = this.value; text.onblur = this.onblur; text.onfocus = this.onfocus; this.replaceWith(text)'></textarea>

您可以使用子项创建嵌套数组，并使用recursive function进行迭代。
这样，您可以根据需要添加任意数量的子级别。

$navItems = array(
    array(
        "slug"   => "index.php",
        "title"  => "Home"
    ),
    array(
        "slug"   => "cruise-partners.php",
        "title"  => "Cruise Partners",
         "subitems" => array(
             array(
                "slug"=>"x.html",
                "title"=>"sub-item.html"
             )
         )

    ),
    array(
        "slug"   => "destinations.php",
        "title"  => "Destinations"
    ),
    array(
        "slug"   => "cruise-deals.php",
        "title"  => "Cruise Deals"
    ),
    array(
        "slug"   => "cruise-type.php",
        "title"  => "Cruise Type",
    ),
    array(
        "slug"   => "river-cruise.php",
        "title"  => "River Cruise"
    ),
    array(
        "slug"   => "luxury.php",
        "title"  => "Luxury"
    ),
    array(
        "slug"   => "contact.php",
        "title"  => "Contacts"
    )
);


function drawMenu($items){
    echo "<ul>";
    foreach($items as $item){
        echo "<li><a href='".$item['slug']."'>".$item['title']."</a>";
        if(isset($item['subitems'])){
            echo "<ul>";
            drawMenu($item['subitems']);
            echo "</ul>";
        }
        echo "</li>";
    }
    echo "</ul>";
}

drawMenu($navItems);

您需要重新构建数组以包含子项。您可以在嵌套时使用我喜欢的Short Array Syntax。

$navItems = 
[ 
    [
        'title' => 'First Option'
        'slug' => 'first-option'
        'sub' => [
                     'title' => 'First Option Sub'
                     'slug' => 'first-option-sub'
                 ],
                 [
                     'title' => 'First Option Sub 2'
                     'slug' => 'first-option-sub-2'
                 ]
    ],
    [

        'title' => 'First Option'
        'slug' => 'first-option'
        'sub' => [
                     'title' => 'First Option Sub'
                     'slug' => 'first-option-sub'
                 ]
    ]
]

当涉及到实际显示子项时，您需要遍历$navItem数组并检查是否存在'sub'。如果它存在，只需以相同的方式循环它。

我发现很难理解你的HTML，所以这可能不是完全相同的结构，但它应该给你这个想法。

<?php foreach ($navItems as $item) { ?>

    <li class="menuitem  submenu-icon-only toplevel-item">
        <a class="active" href="/<?= $item['slug'] ?>">
            <?= $item['title'] ?>
        </a>
    </li>
    <?php if (isset($item['sub']) { ?>

          <?php foreach($item['sub'] as $subItem) { ?>

              <li class="sub-item>
                  <a href="/<? $subItem['slug'] ?>">
                      <?= $subItem['title'] ?>
                  </a>
              </li>

          <?php } ?>           
    <?php } ?>
<?php } ?>
