我正在制作一个俱乐部目录,例如,我想将每页限制在10个俱乐部,但我无法完全理解。我尝试过SmartyPaginate,但它不起作用(与开发人员交谈,告诉我不要使用它)。
俱乐部.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');
?>

俱乐部.tpl

{extends file="layout.tpl"}
{block name=title}Clubs{/block}
{block name=content}
<form name="clubsearch" method="POST" action="{$SCRIPT_NAME}">
    <div class="span-6">

我想得到下一条和上一条,只显示X条记录。我该怎么办?

在您当前的TRY语句中,在您应该获得当前页面之前(假设从查询字符串)

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

然后定义要从DB提取的球杆

$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,第1页从第0条记录中获得10条记录,第2页从第9条记录中获取10条记录等等。

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

并且将链接PREV和NEXT放在smarty模板中。提示在第1页隐藏上一页,在最后一页隐藏下一页

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