如何使用Netbeans使用引导3分页与PHP MVC？

Question

我目前正在创建一个小应用程序，它具有很多内容，我想让这些内容以有组织的方式显示，并且我可以看到这是使用分页的最佳方式。我已经浏览了bootstrap文档，但是我无法解决这个问题，因为我之前从未使用过它。

型号：

public function showFilms($UserID){ 

    //declare new film array 
    $film = array(); 

    //SQL Query Selecting equivalent information to be displayed 
    $sqlQuery = 'SELECT FilmID, Title, Director,YearofRelease, Genre, Image, MainActor, MainActor1, MainActor2, Synopsis FROM films WHERE User ="' . $UserID . '" ORDER BY Title DESC'; 

    // prepare a PDO statement 
    $statement = $this->_dbHandle->prepare($sqlQuery); 
    // Execute PDO statement 
    $statement->execute(); 

    // While loop fetches each row matching query 
    while ($row = $statement->fetch()) { 
     $film[] = array('FilmID' => $row['FilmID'], 
      'Title' => $row['Title'], 
      'User' => $UserID, 
      'Director' => $row['Director'], 
      'YearofRelease' => $row['YearofRelease'], 
      'Genre' => $row['Genre'], 
      'Image' => $row['Image'], 
      'MainActor' => $row['MainActor'], 
      'MainActor1' => $row['MainActor1'], 
      'MainActor2' => $row['MainActor2'], 
      'Synopsis'=> $row['Synopsis'] 
     ); 

    } 
    //returning film array 
    return $film; 

} 

查看：

<div id="FilmArea"> 
    <!-- Count for Films --> 
    <?php 
    if (count($film)) { 
     ?> 
     <br> 
     <!-- Displaying each entry using count of hidden list value of id of entry --> 
     <?php foreach ($film as $list): ?> 
      <!-- Panel Start --> 
      <div class="panel panel-info"> 

       <!-- Panel Header --> 
       <div class="panel-heading"> 
        <h3 class="panel-title" style="font-family: sans-serif; font-size: 20px; color: black; "> 
         <?= ($list['Title']) ?> <small> Directed By : <?= ($list['Director']) ?></small> 
        </h3> 
       </div> 
       <!-- Panel Body --> 
       <div class="panel-body"> 
        <div id='dvdHolder'> 
         <?= ($list['Image'] <> "" ? "<img style='max-width:200px; max-height:200px;' src='Images/{$list['Image']}'/>" : "") ?> 
        </div> 
        <div id='dvdInfo'> 
         <p style='font-weight: bold;'> Year Released : <?= ($list['YearofRelease']) ?></p> 
         <p style='font-weight: bold;'> Film Genre : <?= ($list['Genre']) ?></p> 
         <p style="font-weight: bold;"> Starring : <?= ($list['MainActor']) ?> , <?= ($list['MainActor1']) ?> , <?= ($list['MainActor2']) ?> </p> 
         <p style='font-weight: bold;'> Synopsis : <?= ($list['Synopsis']) ?></p> 
        </div> 
       </div> 
      </div> 
      <!-- End of Foreach Statement for Entry --> 
     <?php endforeach; ?> 
     <!-- Else show this message if user has no entries --> 
     <?php 
    }else { 
     ?> 
     <p><b>No Films Added yet!</b></p> 
    <?php } ?> 
</div> 

控制器：

<?php 
session_start(); 

require_once('Model/UserDataSet.php'); 
require_once('Model/FilmDataSet.php'); 

$view = new stdClass(); 
$view->pageTitle = 'My Vault'; 




$aa = new FilmDataSet(); 
$film = array(); 
$film = $aa->showFilms($_SESSION['Email']); 



require_once('View/home.phtml');

我如何能实现分页任何帮助或信息进入我的应用程序将是伟大的。

Answer 1

首先，您必须编辑查询以获取每页显示的记录数。

$sqlQuery = 'SELECT FilmID, Title, Director,YearofRelease, Genre, Image, MainActor, MainActor1, MainActor2, Synopsis FROM films WHERE User ="' . $UserID . '" ORDER BY Title DESC LIMIT '.$perPage.' OFFSET '.(($page - 1)*$perPage).''; 

要呈现页数，您必须计算总记录数以了解您拥有多少页。当你渲染的页数引导必须把链接到页面的数量，例如：

<li><a href="localhost:3000/films?page=1">1</a></li> 
<li><a href="localhost:3000/films?page=2">2</a></li> 
<li><a href="localhost:3000/films?page=3">3</a></li> 

控制器，你必须捕捉的页面在这种情况下：

$page = htmlspecialchars($_GET["page"]); 
$film = $aa->showFilms($_SESSION['Email'], $page); 

也可以看看这个教程，有实现的方式与类分页：

最后，我建议你使用MVC弗拉姆ework，这可以帮助您大大提高代码的组织性，安全性和分页选项。
