现在。。。我想在无序列表中显示这个。我有以下功能。
public function display($sorted_array)
{
$markup = '';
foreach ($sorted_array as $key => $value)
{
if($key === 'Electronics' || $key ==='Hotels' || $key === 'Services' || $key === 'Entertainment')
{
$markup .= '<h1><li>';
}
$markup .= (is_array($value)) ? '<b>'.$key.'</b></li></ul></h1>'.$this->display($value) : '<ul><li>'.$value. '</li></ul>';
}
return '<ul>'.$markup . '</ul>';
}
Electronics
Home Use
Laptops
HP A very simple laptop
HP Tablet
Acer Laptop
台式机
Acer Tablet
片剂
商业
Tablets
HP A very simple laptop
HP Tablet
Touchmate
笔记本电脑
Compaq
IBM
桌面
Lenovo
酒店
5 Stars
Daily Basis
Hilton
所有类别和子类别都以正确的顺序显示。然而，我需要知道我应该在哪里添加id，这样我就可以将样式添加到子类别中并适当地放置它们。
如果你使用id，那么你会多次使用id，所以使用class而不是id。一种方法是保留一个表示级别的计数器。根据你的功能正常工作，你会得到这样的东西：
public function strip($string)
{
$string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
$string = preg_replace('/[^A-Za-z0-9'-]/', '', $string); // Removes special chars.
$string = strtolower($string); //To lower case
return $string;
}
public function display($sorted_array, $level=0)
{
$level++;
$markup = '';
foreach ($sorted_array as $key => $value)
{
if($key === 'Electronics' || $key ==='Hotels' || $key === 'Services' || $key === 'Entertainment')
{
$markup .= '<h1><li id="'.$this->strip($key).'" class="level-'.$level.'">';
}
$markup .= (is_array($value)) ? '<b>'.$key.'</b></li></ul></h1>'.$this->display($value,$level) : '<ul><li id="'.$this->strip($key).'" class="level-'.$level.'">'.$value. '</li></ul>';
}
return '<ul>'.$markup . '</ul>';
}
现在您可以在css中使用级别类了。
.level-1 {
}
.level-2 {
}
...
