php - 具有 php 功能的活动菜单类

Question

我没有完成它，我需要在函数的输出上放置一个类。

你能帮忙吗，当菜单项active存在时，必须为链接添加一个类。

这是代码：

function loadMenu()
      {
     $result = mysql_query(" SELECT * FROM  cms_page WHERE  site_id =2  AND  page_inmenu =1 AND  page_active =1");
    if ($DEBUG)
         echo "<pre>$result</pre>";
    while($row = mysql_fetch_array($result))
    {   $last_parent = $row['page_name']; 
        echo "<a href={$row['link_name']}>{$row['page_name']}</a>";

         }  
     }

Answer 1

function loadMenu()
{
    $result = mysql_query(" SELECT * FROM  cms_page WHERE  site_id =2  AND  page_inmenu =1 AND  page_active =1");
    if ($DEBUG)
        echo "<pre>$result</pre>";
    while($row = mysql_fetch_array($result))
    {
        $last_parent = $row['page_name']; 
        $class = $row['active'] === true ? ' class="active"' : '';
        echo "<a href=\"{$row['link_name']}\"{$class}>{$row['page_name']}</a>";

    }   
}

I'm not 100% sure about what's your issue.

So, if you aren't displaying anything, probably a MySQL issue.

1- Reference for Mysql (Look at OZ_'s answer) : How to put mysql inside a php function?

2- As mentionned by Beiller, you'll need a way to see if the link is active.

Solution A : Might need some adjustment according $row['link_name'] value.

    $class = ($row['link_name'] == $_SERVER['REQUEST_URI'].)?' class="active" ' : '';

Solution B : Simply stick to CSS - http://www.echoecho.com/csslinks.htm

    .mylink:active{ background-color:pink; }

3- Href needs quotes on around the URL. also, I'm not a big fan of {} inside strings.

    echo "<a href=\"". $row['link_name'] ."\"". $class .">". $row['page_name'] ."</a>";

感谢贝勒的帮助..

这是现在的功能：

function loadMenu(){
     $result = mysql_query(" SELECT * FROM  cms_page WHERE  site_id =2  AND  page_inmenu =1 AND  page_active =1");
    if ($DEBUG)
         echo "<pre>$result</pre>";
    while($row = mysql_fetch_array($result))
    {   $last_parent = $row['page_name']; 
        echo "<a href={$row['link_name']}>{$row['page_name']}</a>";
}}

这是电话：

<div id="header_menu">
           <? loadMenu (); ?>
</div>

mysql有以下表格：

• page_id
• page_name
• 链接名称
• site_id
• order_id
• page_menu
• page_inmenu
• page_leftmenu
• page_text
• page_active
