Question

我目前正在创建一个包含大量内容的小应用程序，我希望以有组织的方式显示内容，并且我可以看到这是使用分页的最佳方式。我已经看了一下bootstrap文档然而我无法理解我将如何使用它，因为我以前从未使用它。

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');

有关如何在我的应用程序中实现分页的任何帮助或信息都会很棒。

Answer 1

首先，您必须编辑查询以获取每页要显示的记录数。

$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，以了解您拥有的页数。当您渲染页数时，Bootstrap必须添加指向页数的链接，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>

控制器在这种情况下你必须捕获页面：

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

您还可以查看本教程，实现了一种用类分页的方法：

最后，我建议您使用MVC框架，这可以帮助您更多地使您的代码更有条理，安全功能并具有分页选项。
