运行截图如下:
前端代码如下:
Student.php
- <!DOCTYPE html>
- <html lang="en">
- <head>
- <meta charset="UTF-8">
- <title>Title</title>
- </head>
- <body>
- <h1>HelloWorld</h1>
- <table border="1" cellspacing="1" cellpadding="1">
- <thead>
- <tr>
- <td>ID</td>
- <td>名字</td>
- <td>年龄</td>
- <td>性别</td>
- <td>邮箱</td>
- <td>地址</td>
- <td>更新时间</td>
- </tr>
- </thead>
- <tbody>
- {foreach $students as $student}
- <tr>
- <td>{$student.id}</td>
- <td>{$student.name}</td>
- <td>{$student.age}</td>
- <td>
- {if $student.sex eq "m"} 男
- {else}女
- {/if}
- </td>
- <td>{$student.email}</td>
- <td>{$student.address}</td>
- <td>{$student.updateTime}</td>
- </tr>
- {/foreach}
- </tbody>
- </table>
- <ul>
- {$pageStr}
- </ul>
-
- </body>
- </html>
后端关键代码
提供数据的:
StudentController.php
- <?php
-
- namespace admin\controller;
- use core\Controller;
- use home\model\StudentModel;
- use vendor\Page;
-
- class StudentController extends Controller{
-
-
- public function student(){
-
- $page = $_REQUEST["page"] ?? 1;
- $studentModel = new StudentModel();
- $students = $studentModel->getAllStudents($page);
- $counts = $studentModel->getCounts();
-
- $cond = array("a" => A, "c" => C, "p" => P);
- $pageStr = Page::clickPage(URL . "index.php", $counts, $cond, $page);
-
- $this->assign("pageStr", $pageStr);
- $this->assign("students", $students);
- $this->assign("counts", $counts);
- $this->display("student.html");
- }
- }
分页代码:
Page.php
- <?php
- namespace vendor;
-
- class Page{
-
- public static function clickPage($url, $counts, $cond = array(), $page = 1, $pageCount = 5): string{
-
- //所有页数
- $pages = ceil($counts / $pageCount);
-
- //上一页和下一页
- $prev = $page > 1 ? $page - 1 : 1;
- $next = $page < $pages ? $page + 1 : $pages;
-
- //url上需要补充的内容
- $patchInfo = "";
- foreach ($cond as $key => $value){
-
- $patchInfo .= $key . "=" . $value . "&";
- }
-
- //先展示上一页
- $click = "<li><a href='{$url}?{$patchInfo}page={$prev}'>上一页</a></li>";
-
- //如果总页数在7以内全都都展示出来
- if($pages <= 7){
-
- for($i = 1; $i <= $pages; $i++){
-
- $click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
- }
- }
- else{ //总页数在7页以上
-
- //如果当前选中页数在5页以内,就把前7页全显示了。
- if($page <= 5){
-
- for($i = 1; $i <= 7; $i++){
-
- $click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
- }
- $click .= "<li><a href='#'>...</a></li>";
- }
- else{
-
- //如果当前选中的在第7页(包括第7页)以上,先展示1,2
- $click .= "<li><a href='{$url}?{$patchInfo}page=1'>1</a></li>";
- $click .= "<li><a href='{$url}?{$patchInfo}page=2'>2</a></li>";
- $click .= "<li><a href='#'>...</a></li>";
-
- //再展示中间页
- //如果是最后3页了,就全部展示出来
- if($pages - $page <= 3){
-
- for($i = $pages - 4; $i <= $pages; $i++){
-
- $click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
- }
- }
- else{ //展示当前页面的前2页,和后2页
-
- for($i = $page - 2; $i <= $page + 2; $i++){
-
- $click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
- }
-
- $click .= "<li><a href='#'>...</a></li>";
- }
- }
- }
-
- //最后补一个下一页
- $click .= "<li><a href='{$url}?{$patchInfo}page={$next}'>下一页</a></li>";
- return $click;
- }
- }
简单说下逻辑:
http://localhost:63343/IT1995Blog/public/index.php?a=student&c=Student&p=admin&page=2
这个page就是当前页,程序里面写死了是每页5条,a=student,c=Student,p=admin是程序里面的逻辑,这个是必须要加的。所以在Page中会补这个。
