分頁從0開始

Question

我有181個產品的數據庫。 我使用PHP來在頁面上顯示產品。 其顯示每頁20個產品，總共有10頁，最後一頁，第10頁只是一個產品。 對於181種產品，分頁從第0頁開始，如< 0 1 2 3..10 >。 對於像180這樣的舍入值，分頁顯示正確< 1 2 3..10 >。

function buildTrail($param = ""){ 

    $cur_page = basename($_SERVER['PHP_SELF']); 
    $link = $_SERVER['REQUEST_URI']; 
    $link_array = explode('/', $link); 
    //$count = count($link_array); 
    $pagename = $link_array[1]; 
    // echo $magename; 
    //echo $link; 

    if(is_array($param)){ 
     foreach($param as $a => $b){ 
      if($a != "page" && $a != "b" && $a != "q" && $a != "oferta"){ 
       $url = "/".$b."/pg/"; 
      }elseif($a == "b"){ 
       $url = "/".$pagename."/brand/".$b."/pg/"; 
      }elseif($a == "oferta"){ 
       $url = "/".$pagename."/".$a."/pg/"; 
      }else{ 
       $url = "/".$pagename."/".$b."/pg/"; 
      } 
     } 
    }else { 
     $url = $param; 
    } 
    // print_r($b); 


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

    return $trail; 
} 

和一個函數來顯示頁碼

function buildTrail($param = ""){ 

    $cur_page = basename($_SERVER['PHP_SELF']); 
    $link = $_SERVER['REQUEST_URI']; 
    $link_array = explode('/', $link); 
    //$count = count($link_array); 
    $pagename = $link_array[1]; 
    // echo $magename; 
    //echo $link; 

    if(is_array($param)){ 
     foreach($param as $a => $b){ 
      if($a != "page" && $a != "b" && $a != "q" && $a != "oferta"){ 
       $url = "/".$b."/pg/"; 
      }elseif($a == "b"){ 
       $url = "/".$pagename."/brand/".$b."/pg/"; 
      }elseif($a == "oferta"){ 
       $url = "/".$pagename."/".$a."/pg/"; 
      }else{ 
       $url = "/".$pagename."/".$b."/pg/"; 
      } 
     } 
    }else { 
     $url = $param; 
    } 
    // print_r($b); 


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

    return $trail; 
} 

Answer 1

在拉斯維加斯要不然這

 for ($i = ($this->getPages() - 10); $i <= $this->getPages(); $i ++){ 
      $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . $url. $i ."'>" . $i . "</a>\n "; 
     } 

與

  for ($i = 1; $i <= $this->getPages(); $i ++){ 
       $trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . $url. $i ."'>" . $i . "</a>\n "; 
      }
