Question

我是使用PHP的新手，在此导航之前我的PHP使用范围很简单。

我编写了一个navigation.php文件，该文件使用从variables.php中的数组中提取的变量动态生成导航链接

总体目标是仅通过编辑variables.php

来添加/减去链接，子动画，子子动画，子子动画。

我用来生成HTML结构的方法对我来说很笨拙，它运行得很好，但我觉得有一种更简单的方法可以做到这一点......

此外，我需要为任何存在子区域的LI提供额外的样式（箭头表示存在子区域）。我想动态生成它。

那说我的问题是：

有更简单的方法吗？
有没有办法根据是否存在子导航来动态生成我的？

每个页面都有以下代码，它会根据页面而变化。

<?php $title = 'Home'; ?>

我的变量.php：

<!-- NAVIGATION ARRAY -->

<?php
$nav_mini = array(
    'Home' => 'index.php',
    'About' => 'about.php',
    'Services' => 'services.php'
    );
?>

<?php
$nav_main = array(
    'Home' => 'index.php',
    'About' => 'about.php',
    'Services' => 'services.php',
    'Portfolio' => 'contact.php',
    'Clients' => 'about.php',
    'Gallery' => 'services.php',
    'News' => 'services.php',
    'Contact Us' => 'contact.php'
    );
?>

<?php // SUB NAV ARRAYS

$nav_sub_about = array(
    'Our Team' => 'about.php'
    );

$nav_sub_michael = array(
    'Michael' => 'index.php',
    'Aaron' => 'about.php',
    'Kenny' => 'about.php',
    'David' => 'about.php'
    );

$nav_sub_services = array(
    'Get Found' => 'about.php'
    );

?>

导航PHP文件main-nav.php

    <?php 

        foreach ( $nav_main as $key => $value ) {

            echo "<li><a ";
                echo "class='"; // STARTS CLASS=
                if ( $title == $key) { 
                echo "active "; }// ADDS ACTIVE CLASS TO LINK OF CURRENT PAGE
            echo "' "; // END QUOTES FOR CLASS="


            echo "href='$value'>$key";

                if ( $key == "About") { // STARTS IF SEQUENCE FOR SUBNAV ARROWS
                    echo "<span class='arrow'> +</span>";}
                elseif ( $key == "Services") {
                    echo "<span class='arrow'> +</span>";}

            echo "</a>\n";  // END ANCHOR TAG FOR MAIN NAV LINKS



//----------------------------------------------------------------------------------------------------------//
// PLEASE START SUB-NAVS HERE ------------------------------------------------------------------------------//
// AT THIS POINT A NEW <LI> IS GENERATED FROM THE FIRST FOREACH, IF THE BELOW IS TRUE IT POPULATES A SUBNAV //      


        if ( $key == "About"){  // START SUBNAV FOR ABOUT
            echo "<ul class='main-sub-nav'>"; // THIS LINE WAS ADDED TO START THE <UL> FOR THE SUBNAV, IT ENDS ON LINE 14

            foreach ( $nav_sub_about as $key => $value ) {
                echo "<li><a href='$value'>$key";

                    if ( $key == "Our Team") { // STARTS IF SEQUENCE FOR SUBNAV ARROWS
                    echo "<span class='arrow'> +</span>";}

                echo "</a>\n"; // ENDS ANCHOR TAG FROM SUBNAV LI

                    // SUB-SUB-NAV STARTS HERE
                        if ( $key == 'Our Team') {
                        echo "<ul class='main-sub-sub-nav'>"; // THIS STARTS THE UL FOR SUB-SUB-NAV

                            foreach ($nav_sub_michael as $key => $value ) {
                        echo "<li><a href='$value'>$key</a></li>\n";
                    }
                    echo "</ul>"; // THIS ENDS THE SUB-SUB-NAV UL STARTED ON LINE 34
                echo "</li>";}// THIS IS THE END IF <LI> FROM THE SECOND FOREACH ON LINE 35

        }

        echo "</ul>"; // THIS WAS ADDED TO END THE SUBNAV <UL> STARTED ON LINE 11
        echo "</li>";} // THIS IS THE END OF THE <LI> FROM THE FIRST FOREACH ECHO FROM LINE 8

//----------------------------------------------------------------------------------------------------------//
// AT THIS POINT A NEW <LI> IS GENERATED FROM THE FIRST FOREACH, IF THE BELOW IS TRUE IT POPULATES A SUBNAV //

            if ( $key == "Services"){
                echo "<ul class='main-sub-nav'>"; // THIS LINE WAS ADDED TO START THE <UL> FOR THE SUBNAV, IT ENDS ON LINE 14

                foreach ( $nav_sub_services as $key => $value ) {
                    echo "<li><a href='$value'>$key</a></li>\n";}
                echo "</ul>"; // THIS WAS ADDED TO END THE SUBNAV <UL> STARTED ON LINE 11
                echo "</li>";} // THIS IS THE END OF THE <LI> FROM THE FIRST FOREACH ECHO FROM LINE 8



        } // THIS BRACKET ENDS THE ENTIRE SET OF PHP.  ITS PAIR IS ON LINE 19

?>

总体目标是仅通过编辑variables.php

以下是此导航结构工作的实例... http://khill.mhostiuckproductions.com/siteLSSBoilerPlate/

Answer 1

你正在做的事情几乎就是现场，但是你正在自己编写自己的代码而是允许它是通用的，所以编写一个函数，如果需要，可以调用自己来执行此操作：

$menu_items = array(
    'Home' => 'index.php'
    'About' => array('about.php', 
         array('Our Team'=>'ourteam.php'),
     etc
    );
?>

从<ul>
遍历给定数组
添加<li>
如果是is_string（），则只有一项附加<a href>
如果is_array（）有子项，
- 添加<a href>
- 将第二个元素发送到此函数并附加返回的html
关闭</li>
关闭</ul>
返回

一个函数处理所有元素，无论它们是main还是sub，无论你有多少个子列表，都可以调用它一次完成列表。

现在，对于您的迷你菜单，只需通过键（Home，About，Services）从主数组中选择元素，然后使用一个函数创建html

Answer 2

更清洁的解决方案是使用multidimensional arrays然后iterate through构建导航。如果数组的value是另一个数组，那么你知道它有一个子菜单。

PHP导航，有更好的方法吗？
