我正在制作一个俱乐部目录,我想限制每个页面到10个俱乐部,但我无法绕过它。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)。
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
$smarty->display('extends:layout.tpl|header.tpl|clubs.tpl|footer.tpl');
?>
clubs.tpl
{extends file="layout.tpl"}
{block name=title}Clubs{/block}
{block name=content}
<form name="clubsearch" method="POST" action="{$SCRIPT_NAME}">
<div class="span-6">

<td>{$c.Categorie}</td>
<td>{$c.Provincie}</td>
<td>{$c.Gemeente}</td>

{/foreach}
</table>
{/if}
{/block}
我想获得下一个和上一个并且仅显示X量的记录。我怎么能这样做呢?
答案 0 :(得分:0)
在您当前的TRY语句中,在您应该获取当前页面之前(假设来自查询字符串)
$page = empty($_GET['page']) ? 1 : (int)$_GET['page'];
然后定义要从DB中获取的球杆
$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");
基本上你从第1页的第0条记录中获得10条记录,从第2页的第9条记录获得10条记录,等等。
page 1 LIMIT 0,10
page 2 LIMIT 9,10
page 3 LIMIT 19,10
和caurse将链接PREV和NEXT放在smarty模板中。提示在第1页隐藏PREV并在最后一页隐藏NEXT
<a href="your_url.php?page=$page-1">PREV</a>
<a href="your_url.php?page=$page+1">NEXT</a>
