分页问题有多个参数

Question

我有一个分页类，对于网址工作篦状

http://localmachine/c/category-name 

分页链接看起来像

http://localmachine/c/category-name/page-2 

但是，如果我添加其他参数基本URL，如：

http://localmachine/c/category-name/brand-Coca+Cola 

了分页链接将

http://localmachine/brand/Coca+Cola/c/category-name/page-2 

我怎样才能解决这个问题，显示一个类似

http://localmachine/c/category-name/brand/Coca+Cola/page-2 

这是一个显示分页链接我的分页功能，分页链接。

function buildTrail($param = ""){ 


    if(is_array($param)){ 
     foreach($param as $a => $b){ 
      if($a != "page"){ 
       $url .= $a . "/" . urlencode($b).'/'; 
      }else{ 
       $url .= ''; 
      } 
     } 
    } else { 
     $url = $param; 
    } 

    //$location = basename($_SERVER['REQUEST_URI']); 



    $trail = ""; 
    if($this->getPages() > 1){ 
     if($this->getFrom() > 1){ 
     $trail .= "<a href='" . WEBSITE . "/". $url . "page-" . $this->getPrevious() . "'>&laquo;</a>\n "; 
     } 

     if($this->getFrom() < 10 && $this->getPages() > 10){ 
      for ($i = 1; $i <= 10; $i++){ 
       $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . "/". $url . "page-" . $i . "'>" . $i . "</a>\n "; 
      } 
     } elseif($this->getFrom() < 10 && $this->getPages() < 10){ 
      for ($i = 1; $i <= $this->getPages(); $i++){ 
       $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . "/". $url . "page-" . $i . "'>" . $i . "</a>\n "; 
      } 
     }elseif ($this->getFrom() >= 10 && $this->getFrom() <= ($this->getPages() - 5)){ 
      for ($i = ($this->getFrom() - 5); $i <= ($this->getFrom() + 5); $i ++){ 
       $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . "/". $url . "page-" . $i . "'>" . $i . "</a>\n "; 
      } 
     } else {    
      for ($i = ($this->getPages() - 9); $i <= $this->getPages(); $i ++){ 
       $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . "/". $url . "page-" . $i . "'>" . $i . "</a>\n "; 
      } 
     } 
     if($this->getFrom() < $this->getPages()){ 
     $trail .= "<a href='" . WEBSITE . "/". $url . "page-" . $this->getNext() . "'>&raquo;</a>\n "; 
     } 
    } 

    return $trail; 
}

我会做这样的：

// Create array with preferred order of parameters first. 
    // Make sure to list all possible params here excluding page 
    $preferedOrder = array('c', 'brand'); 

    $paramsArray = array(); 

    foreach ($preferedOrder as $v) { 

     // Based on the type of parameter combine it with/or - . Put everything to array. 
     if (isset($param[$v])) { 
      if ($v == 'c') { 
       $paramsArray[] = $v . '/' . urlencode($param[$v]); 
      } else { 
       $paramsArray[] = $v . '-' . urlencode($param[$v]); 
      } 
     } 
    } 

    // Implode array with '/' 
    $url = implode('/', $paramsArray); 

在这种情况下，所有的参数将在需要的顺序和页面不会在那里。
