我有一个简单的 PHP MySQLi 分页脚本，每页显示 5 个条目。但对于大型数据库条目，会显示相当多的页码。如何限制分页中显示的页数？例如。一次 10 页： 第一个 < 1 2 3 4 5 6 7 8 9 10 > 最后一个
这是我的代码：
<!DOCTYPE html><html>
<head>
<title>PHP Pagination</title>
</head>
<body>
<?php
// Establish Connection to the Database
$con = mysqli_connect('localhost','root','','classicmodels');
//Records per page
$per_page = 5;
if (isset($_GET["page"])) {
$page = $_GET["page"];
}
else {
$page = 1;
}
// Page will start from 0 and Multiple by Per Page
$start_from = ($page-1) * $per_page;
//Selecting the data from table but with limit
$query = "SELECT * FROM customers LIMIT $start_from, $per_page";
$result = mysqli_query ($con, $query);
?>
<table align="center" border="2″ cellpadding="3″>
<tr><th>Name</th><th>Phone</th><th>Country</th></tr>
<?php
while ($row = mysqli_fetch_assoc($result)) {
?>
<tr align="center">
<td><?php echo $row['contactFirstName']; ?></td>
<td><?php echo $row['contactLastName']; ?></td>
</tr>
<?php
};
?>
</table>
<div>
<?php
//Now select all from table
$query = "select * from customers";
$result = mysqli_query($con, $query);
// Count the total records
$total_records = mysqli_num_rows($result);
//Using ceil function to divide the total records on per page
$total_pages = ceil($total_records / $per_page);
//Going to first page
if($_GET['page'] != 1) {
echo "<center><a href='index.php?page=1'>".'First Page'."</a>";
} else echo "<center>";
echo "<a href='index.php?page=" . ($_GET['page']+1) . "'>Next Page</a>";
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='index.php?page=".$i."'>".$i."</a> ";
};
echo "<a href='index.php?page=" . ($_GET['page']-1) . "'>Previous Page</a>";
// Going to last page
if($_GET['page'] != $total_pages) {
echo "<a href='index.php?page=$total_pages'>".'Last Page'."</a></center> ";
} else echo "</center>";
?>
</div>
</body>
</html>
你可以像这样实现一个分页器（简单版本，需要改进）：
<?php
$totalPages = 28; //replace with database value
$currentPage = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$numPagesToShow = 10; //it's up to you
//avoid bug or trying to get page out of the bounds
if($currentPage > $totalPages) {
$currentPage = $totalPages;
}
/* correct the number of pages to show on the left or right
* and always try to put the current page in the middle
*/
if($numPagesToShow >= $totalPages) {
$numMaxPageLeft = 1;
$numMaxPageRight = $totalPages;
} else {
$pagesToShow = ceil($numPagesToShow/2);
$numMaxPageLeft = $currentPage - $pagesToShow;
$numMaxPageRight = $currentPage + $pagesToShow;
if($numMaxPageLeft <= 0) {
$numMaxPageRight = $numMaxPageRight - $numMaxPageLeft +1;
$numMaxPageLeft = 1;
} elseif($numMaxPageRight >= $totalPages) {
$numMaxPageLeft -= ($numMaxPageRight - $totalPages);
$numMaxPageRight = $totalPages;
}
}
//loop to show all desired pages
for ($i=$numMaxPageLeft; $i<=$numMaxPageRight; $i++) {
echo $i == $currentPage ? $i : "<a href='index.php?page=".$i."'>".$i."</a> ";
}
