어떻게 다른 페이지에 데이터를 표시합니까?

Question

나는 & 포스트를 변경했지만 아무 것도주지 못했습니다.이 부분을 여기서 어렵게 만드는 형태라고 생각합니다. 잘못된 것입니까? 나는 GET &을 위해 '이동'& 내가 정의되지 않은 인덱스 말하는 오류를 얻을 POST '제출'이야기하지만 확실히 아는 한 가지는 내가 '이름'을 사용할 때와하지 수 없습니다, '이름', 무슨 일이 최대를 내가 네가 한 말을했지만 아무것도하지 않았어!

나는 간단하고 깨끗한 코드 여기

간단한 매김 클래스입니다 제안 :?를 .PHP 파일에 저장

class Pagination { 

    public $current_page; 
    public $per_page; 
    public $total_count; 

    public function __construct($page=1, $per_page=20, $total_count=0){ 
    $this->current_page = (int)$page; 
    $this->per_page = (int)$per_page; 
    $this->total_count = (int)$total_count; 
    } 

    public function offset() { 

    return ($this->current_page - 1) * $this->per_page; 
    } 

    public function total_pages() { 
    return ceil($this->total_count/$this->per_page); 
    } 

    public function previous_page() { 
    return $this->current_page - 1; 
    } 

    public function next_page() { 
    return $this->current_page + 1; 
    } 

    public function has_previous_page() { 
     return $this->previous_page() >= 1 ? true : false; 
    } 

     public function has_next_page() { 
      return $this->next_page() <= $this->total_pages() ? true : false; 
     } 
} 

및이를 포함 귀하의 페이지에 여기 사용 방법은 다음과 같습니다 :

$ 페이지 매김 = 새로운 쪽 매김 ($ curent_page, $ per_page, $ total);

$curent_page // get it from url with GET method 
e.g 
$curent_page = isset($_GET['page'])&&(int)$_GET['page'] !=0 ? (int)$_GET['page'] : 1 ; 

-

$per_page // you have to define how many rows do you want to show in the page 
e.g 
$per_page = 20 ; 

-

$total // you have to count all of the rows in your table 

e.g 
    $sql = "SELECT COUNT(*) FROM `$tbl` "; 
    $result = mysql_query($sql , $db_connection); 
    $total = mysql_result($result , 0); 


now you can create a pagination obj 
$pagination = new Pagination($curent_page , $per_page , $total); 

-

 $pagination->offset() // use this as offset in your query in each 
    page 

$pagination->per_page // use this as LIMIT in your query 

     e.g 
     $rows_to_show = "SELECT * FROM `$tbl` LIMIT {$pagination->per_page} OFFSET {$pagination->offset()}";  

마지막 페이지의 하단에있는 HTML 페이지 매김을 만드는

if($pagination->total_pages() > 1){ 
      echo '<div id="pagination_div">'; 
       if($pagination->has_next_page()){ 

       echo '<span><a href="index.php?page='.$pagination->next_page(); 
       echo'" >> </a></span>' ; 

       } 
       for($i=1 ; $i <= $pagination->total_pages() ; $i++){ 
       if($i == $pagination->current_page){ 
       echo '&nbsp;<strong>'.$i.'&nbsp;</strong>'; 
       } 
       else {     
       echo '<span><a href="index.php?page='.$i; 
       echo'"> '.$i.' </a></span>'; 
       } 
       } 
       if($pagination->has_previous_page()){ 

       echo'<span><a href="index.php?page='.$pagination->previous_page(); 
       echo'" > < </a></span>'; 
       } 

      echo ' </div> '; 

      }

/// $name may be sent to the page via post/form OR via get/url so you have to be prepare for both , so this is how you get $name at the top of page

if(isset($_GET['name'])) 
$raw_name = $_GET['name'] ;
