Question

我正在尝试为我的项目添加分页。在我进入页面的那一刻，分页从Page = 0开始，我可以浏览页面。

URL如下所示：*domain*.com/users/?pageNr=0（使用GET方法按钮更改页码）

输入搜索输入后，网址将更改为：*domain*.com/users/?input=JohnDoe&action=search

但是当我尝试在页面之间移动时，搜索值会从网址中删除，我会再次看到未经过滤的数据（pageNr=0）。

是否可以在网址中保留搜索值并将pageNr附加到其中，还是应该更改我的分页方法？编辑：数据

$action = filter_input(INPUT_GET,'action',FILTER_SANITIZE_STRING);
$input = filter_input(INPUT_GET,'input',FILTER_SANITIZE_STRING);

$pageNr = filter_input(INPUT_GET, 'pageNr', FILTER_VALIDATE_INT);
$next = $pageNr+1;
$previous = $pageNr-1;

if(empty($pageNr)) {
    $pageNrInDb = 0;
} else {
    $pageNrInDb = $pageNr * MAX_USERS_ON_PAGE;
}

$countUsers = User::count_all();

$pagesCount = ceil( $countUsers / MAX_USERS_ON_PAGE);

if (isset($action) && $action ==='search'){
    if (!User::find_by_username($input)) {
        echo infoMessage('info', 'No results to <b>' . $input . '</b>');
        $users = User::findAll($pageNrInDb, MAX_USERS_ON_PAGE);
    } else {
        $users = User::find_by_username($input);
    }
} else {
    $users = User::findAll($pageNrInDb, MAX_USERS_ON_PAGE);
}

您只需要使用您的分页表单发送初始值，请尝试以下操作：

<form method="get">
        <li>
            <div class="btn-group">
                <?php $pageNr == 0 ? $disabled = "disabled='disabled'" : $disabled = ''; ?>
                <button class="btn btn-default btn-xs" <?php echo $disabled ?> type="submit" name="pageNr" value="<?php echo $previous ?>"><span class="glyphicon glyphicon-arrow-left"></span></button>
                <?php for ($i = 0;$i < $pagesCount;$i++) : ?>
                    <?php $pageNr == $i ? $active = 'active' : $active = '';?>
                    <button class="btn btn-default btn-xs <?php echo $active ?>" style="font-weight: bold;" type="submit" name="pageNr" value="<?php echo $i ?>"><?php echo $i+1 ?></button>
                <?php endfor; ?>
                <?php $pageNr == $pagesCount-1 ? $disabled = "disabled='disabled'" : $disabled = ''; ?>
                <button class="btn btn-default btn-xs" <?php echo $disabled ?> type="submit" name="pageNr" value="<?php echo $next ?>"><span class="glyphicon glyphicon-arrow-right"></span></button>
            </div>
        </li>
        <!-- Add these lines -->
        <input type="hidden" name="action" value="<?= $action ?>">
        <input type="hidden" name="input" value="<?= $input ?>">
</form>

您可以看到我在表单中添加了2个隐藏字段，当页面发生变化时，它们会发送input和action值。

使用数据
