將PHP中的引導程序分頁限制為5頁
[英]Limiting bootstrap pagination in PHP to 5 pages
問題描述
我正在嘗試在顯示5頁的PHP中創建分頁。
在首頁上時，我們有：
[1] [2] [3] [4] [5] ... [325] [>>]
單擊[325]將帶您到該頁面（最后一條記錄），單擊向右箭頭將帶您到[2]頁面。
在第二頁上時，我們有：[<<] [1] ... [2] [3] [4] [5] [6] ... [325] [>>]
在最后一頁上有：
[<<] [1] ... [321] [322] [323] [324] [325]
我一直在研究如何做到這一點。 我想我知道，當我們位於除第一頁或最后一頁之外的任何頁面上時，需要在活動頁面的每一側創建一個相鄰頁面為2的數組。 我還需要創建一個<li><a href="site_members.php?Page=1">1</a></li>
和
<li><a href="site_members.php?Page=<?php echo $last_record; ?>"><?php echo $last_record; ?></a></li>
當用戶不在第一條或最后一條記錄之外的任何地方時。
我有以下代碼，效果很好，但是當我們開始獲取大量記錄時，分頁計數變得可笑。
<ul class="pagination pull-left pagination-md">
<?php
// Creates back button in pagination
if(isset($page)) {
if($page > 1) {
$page_minus = $page-1;
echo "<li><a href='blog.php?page=$page_minus'> « </a></li>";
}
}
?>
<?php
global $con;
$q_pagination = mysqli_prepare($con, "SELECT COUNT(*) FROM admin_panel WHERE ");
$q_pagination->execute();
$result_pagination = $q_pagination->get_result();
$rows_result = $result_pagination->fetch_array();
$total_rows = array_shift($rows_result);
$post_per_page = $total_rows/15;
$post_per_page = ceil($post_per_page);
for($i = 1; $i <= $post_per_page; $i++) {
if(isset($page)){
if($i == $page) {
echo "<li class='active'><a href='blog.php?page=$i'>$i</a></li>";
}
else {
echo "<li><a href='blog.php?page=$i'>$i</a></li>";
}
}
}
// Creates the forward button in pagination
if(isset($page)){
if($page+1 <= $post_per_page) {
$page_plus = $page+1;
echo "<li><a href='blog.php?page=$page_plus'> » </a></li>";
}
}
?>
</ul>
我承認，在研究並嘗試完成這項工作之后，我只是在邏輯上變得扭曲。 是否有人對如何最好地解決此問題有任何想法？ 潛在客戶，當前示例等。我發現的大多數內容都是過時的，不完整的或愚蠢的。
