PHP의 페이지 매김 관련 문제

Question

현재 2 개의 테이블을 가지고 있으며 데이터가 동적입니다.

두 테이블에 페이지 매김을 별도로 추가해야합니다. paginator 클래스를 사용하여 paginator를 추가 했으므로 제대로 작동합니다. 하지만 문제는 첫 번째 테이블의 다음 버튼을 클릭하면 두 테이블의 내용이 다음 페이지로 변경됩니다.

Paginator.php

Answer 1

문제는 어디에 있습니까?

Paginator 클래스는 동일한 쿼리 문자열 "page"매개 변수를 사용하여 현재 페이지를 계산합니다. 동일한 요청에 2 개 이상의 페이지 매김을 추가하면 "페이지"가 ​​모든 인스턴스에서 공유되어 설명 된 엉망으로 이어집니다.

문제를 해결하는 방법은 무엇입니까? 매기기 클래스

// constructor 
function Paginator($get_var=null) { 
    if ($get_var!=null) $this->get_var = $get_var; 
} 

단계에서 생성자를 대체을 :

1 단계 :

아래이 2 단계 패치를 따라 ... 쿼리 문자열에서 사용하는 매개 변수 매기기 클래스에게 2 : 업데이트 페이지 매김 개체 생성 (두 번)

$online_paginate = new Paginator('page_table1'); 

이상 :

희망이 있습니다.
