PHP SMARTY 樣板引擎

  1. 在admin_nav.php
    22行附近，stopLevel 設為2 #foreign key $foreign = array( "menuTop" => array("title" => "上方選單","stopLevel"=>2), "menuFoot" => array("title" => "頁尾選單","stopLevel"=>1) );

     

  2. 至後台輸入幾個2層選單
  3. 至foot.php
    可以取消註解 「//print_r($menuTop);die();」看一下資料是否正確 #----得到下拉選單 #引入選單物件 include_once WEB_PATH . "/class/ugmKind.php";; #實體化 類別物件 $tbl = "{$WEB['moduleName']}_kind";//取得主要資料庫 $kind = "menuTop"; $stopLevel = 2; //層數 $moduleName = $WEB['moduleName'];          //專案名稱 //(資料表,分類，層數，父層) $ugmKind = new ugmKind($tbl, $kind, $stopLevel,$moduleName);// $menuTop = $ugmKind->get_listArr(); $smarty->assign("menuTop", $menuTop); //print_r($menuTop);die(); #---------------------------------

     

  4. 分析二層的選單樣板 <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item"> <a class="nav-link disabled" href="#">Disabled</a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown04" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a> <div class="dropdown-menu" aria-labelledby="dropdown04"> <a class="dropdown-item" href="#">Action</a> <a class="dropdown-item" href="#">Another action</a> <a class="dropdown-item" href="#">Something else here</a> </div> </li> </ul>

    只有一層時

    <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li>


    有二層時的樣板
     

    <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown04" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a> <div class="dropdown-menu" aria-labelledby="dropdown04"> <a class="dropdown-item" href="#">Action</a> <a class="dropdown-item" href="#">Another action</a> <a class="dropdown-item" href="#">Something else here</a> </div> </li>

    後台送來的變數得知，如果有 「sub」有值，則有第2層

  5. 樣板(請根據佈景調整) <ul class="navbar-nav mr-auto"> <{foreach from=$menuTop item=row}> <{if $row.sub}> <{* 有2層 *}> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="<{$row.url}>" id="dropdown<{$row.sn}>" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><{$row.title}></a> <div class="dropdown-menu" aria-labelledby="dropdown<{$row.sn}>"> <{foreach from=$row.sub item=row2}> <a class="dropdown-item" href="<{$row2.url}>"<{if $row2.target}>target="_blank"<{/if}>><{$row2.title}></a> <{/foreach}> </div> </li> <{/else}> <{* 只有一層 *}> <li class="nav-item"> <a class="nav-link" href="<{$row.url}>" <{if $row.target}>target="_blank"<{/if}>><{$row.title}></a> </li> <{/if}> <{/foreach}> </ul>
