分页(上一页|下一页)与Smarty [英] Pagination (Previous | Next) with Smarty

问题描述

我正在制作俱乐部的目录，例如，我想将每页限制为10个俱乐部，但是我无法将其包围.我已经尝试过SmartyPaginate，但是它不起作用(告诉开发人员，告诉我不要使用它.)

I'm making a catalogue of clubs and I'd like to limit every page to 10 clubs for example, but I can't wrap my head around it. I've tried SmartyPaginate, but it doesn't work (spoke to the developer, told me not to use it).

clubs.php

clubs.php

<?php

include('configs/pdo.inc.php');
include('libs/Smarty.class.php');

// create object
$smarty = new Smarty;

// Clubs ophalen
try {
    $query = $oPDO->prepare("SELECT * FROM V_clubs WHERE Zichtbaar = 1 ORDER BY ID ASC LIMIT 10");
    $query->execute();

    $t = array();
    foreach ($query as $row) {
        $t[$row['ID']] = $row;
    }

    $smarty->assign('clubs', $t);

    // Categorieen ophalen
    $categorie = $oPDO->query("SELECT * FROM t_categorie ORDER BY D_categorie ASC");
    $smarty->assign('categorie', $categorie);
    // Provincies ophalen
    $prov = $oPDO->query("SELECT * FROM t_provincies ORDER BY D_provincie ASC");
    $smarty->assign('prov', $prov);
    // Clubteller
    $xclubs = $oPDO->prepare("SELECT ID from V_clubs");
    $xclubs->execute();
} catch (PDOException $e) {
    echo '<pre>';
    echo 'Regelnummer: ' . $e->getLine() . '<br>';
    echo 'Bestand: ' . $e->getFile() . '<br>';
    echo 'Foutmelding: ' . $e->getMessage() . '<br>';
    echo '</pre>';
}

// display it
$smarty->display('extends:layout.tpl|header.tpl|clubs.tpl|footer.tpl');
?>

我想获取下一个和上一个，并且仅显示X条记录.我该怎么办?

I'd like to get Next and Previous and show only X amount of records. How can I go about this ?

推荐答案

在当前TRY语句中，首先应该获得当前页面(假设来自查询字符串)

In your current TRY statement, before all you should get your current page (suppose from the query string)

$page = empty($_GET['page']) ? 1 : (int)$_GET['page'];

，然后定义要从数据库中获取的俱乐部

and then define the clubs to fetch from the DB

$start_from = $page == 1 ? 0 : (($page - 1) * 10 - 1);
$query = $oPDO->prepare("SELECT * FROM V_clubs WHERE Zichtbaar = 1 ORDER BY ID ASC LIMIT ".$start_from.", 10");

基本上，您从第1页的第0条记录中获得10条记录，从第2页的第9条记录中获得10条记录，等等.

Basically you are getting 10 records from 0th record for page 1, 10 records from 9th record for page 2, etc.

page 1 LIMIT 0,10
page 2 LIMIT 9,10
page 3 LIMIT 19,10

and caurse将链接PREV和NEXT放入smarty模板中.提示在第1页中隐藏PREV，在最后一页中隐藏NEXT

and of caurse put links PREV and NEXT in the smarty template. Hint hide PREV in page 1 and hide NEXT in the last page

<a href="your_url.php?page=$page-1">PREV</a>
<a href="your_url.php?page=$page+1">NEXT</a>
