HTML和PHP回声

今天我完成了我的标记，所以我想在php中移动它。所以我有导航仪。 

<nav id="cd-vertical-nav">
<ul>
    <li>
        <a href="#destinations" data-number="1" class="">
            <span class="cd-dot"></span>
            <span class="cd-label">Choose Destinations</span>
        </a>
    </li>
    <li>
        <a href="#activities" data-number="2" class="">
            <span class="cd-dot"></span>
            <span class="cd-label">Activities</span>
        </a>
    </li>
    <li>
        <a href="#accommodation" data-number="3" class="">
            <span class="cd-dot"></span>
            <span class="cd-label">Accommodation</span>
        </a>
    </li>
    <li>
        <a href="#transportation" data-number="4" class="is-selected">
            <span class="cd-dot"></span>
            <span class="cd-label">Transportation</span>
        </a>
    </li>
    <li>
        <a href="#maspindzei" data-number="5" class="">
            <span class="cd-dot"></span>
            <span class="cd-label">Choose your Host</span>
        </a>
    </li>
    <li>
        <a href="#contactinfo" data-number="6" class="">
            <span class="cd-dot"></span>
            <span class="cd-label">Contact Information</span>
        </a>
    </li>
</ul>

所以我需要创建一个像这样工作的新功能。

CreateNewSection($secid);

我为此尝试了此代码。

function CreateNewSection($secid)
{
    switch($secid)
    {
        case 1:
        {
            echo '<nav id="cd-vertical-nav">
        <ul>
            <li>
                <a href="#destinations" data-number="1" class="">
                    <span class="cd-dot"></span>
                    <span class="cd-label">Choose Destinations</span>
                </a>
            </li></ul></nav>';  
        }
        case 2:
        {
            echo '<nav id="cd-vertical-nav"><li><a href="#activities" data-number="2" class=""><span class="cd-dot"></span><span class="cd-label">Activities</span></a></li></li></ul></nav>';
        }
    }   
}

问题是，当我呼叫ID 1时，它仍然呼叫id 2。这是我的第一次，当我将标记转换为这样的函数时。

以下是switch-case应该是的方式，每个case都有break，然后最后有default：

switch($secid)
{
    case 1:
    // code here....
    break;

    case 2:
    // code here....
    break;

    default:
    // code here....
}

因此，您的代码应更新如下：

function CreateNewSection($secid)
{
    switch($secid)
    {
        case 1:
        echo '<nav id="cd-vertical-nav">
<ul>
<li>
<a href="#destinations" data-number="1" class="">
<span class="cd-dot"></span>
<span class="cd-label">Choose Destinations</span>
</a>
</li></ul></nav>';  
        break;

        case 2:
        echo '<nav id="cd-vertical-nav"><li><a href="#activities" data-number="2" class=""><span class="cd-dot"></span><span class="cd-label">Activities</span></a></li></li></ul></nav>';
        break;
    }   
}

开关盒末端缺少断裂，导致它掉落。

function CreateNewSection($secid)
{
    switch($secid)
    {
        case 1:
            echo '<nav id="cd-vertical-nav">
        <ul>
            <li>
                <a href="#destinations" data-number="1" class="">
                    <span class="cd-dot"></span>
                    <span class="cd-label">Choose Destinations</span>
                </a>
            </li></ul></nav>';  
            break;
        case 2:
            echo '<nav id="cd-vertical-nav"><li><a href="#activities" data-number="2" class=""><span class="cd-dot"></span><span class="cd-label">Activities</span></a></li></li></ul></nav>';
            break;
    }   
}

我强烈建议放弃冗长的switch-case块的想法。有一种更清洁的方式...

更多DRY并且更容易管理将html的动态部分存储在数组中，然后只需将这些值注入其他静态html中。稍后你会感谢自己走这条路。

function CreateNewSection($secid,$class=''){
    $secs=[
        1=>['href'=>'#destinations','label'=>'Choose Destinations'],
        2=>['href'=>'#activities','label'=>'Activities'],
        3=>['href'=>'#accommodation','label'=>'Accommodation'],
        4=>['href'=>'#transportation','label'=>'Transportation'],
        5=>['href'=>'#maspindzei','label'=>'Choose your Host'],
        6=>['href'=>'#contactinfo','label'=>'Contact Information']
    ];

    if(!isset($secs[$secid])){
        // echo some default behavior or error message
    }else{
        $sec=$secs[$secid]; // merely to shorten the variable
        echo "<li>";
            echo "<a href=\"{$sec['href']}\" data-number=\"{$secid}\" class=\"{$class}\">";
                echo "<span class=\"cd-dot\"></span>";
                echo "<span class=\"cd-label\">{$sec['label']}</span>";
            echo "</a>";
        echo "</li>";
    }
}
echo "<nav id=\"cd-vertical-nav\">";
    echo "<ul>";
        $selected=4;
        for($x=1; $x<7; ++$x){
            CreateNewSection($x,($x==$selected?'is-selected':''));
        }
    echo "</ul>";
echo "</nav>";

*注意我在回声中有{}卷曲括号的所有变量（即使字符串变量不需要它），因此变量在文本编辑器中突出（或者可以< / em>如果您的编辑器设置为这样做。）

switch语句是一种循环形式，为了成功执行循环，需要在每个case语句块的末尾添加一个break语句。语法如下所示

考虑到这一点，您的代码现在应该如下所示

switch($param){

    case $value1: // executes if $param = $value1

        //execute your code

    break; //the break statement forces the processing out of the loop after execution

    case $value2: // executes if $param = $value2

        //execute your code

    break; //the break statement forces the processing out of the loop after execution

    default: 
        //code here executes only if the case 1 and 2 is not matched

}

}
