Codeigniter 4 分页正在工作,但是,我的 bootstrap 4 分页模板不起作用

Codeigniter 4 Pagination is working, however, my bootstrap 4 template for pagination is not

我正在使用 CI4。我已经成功实现了分页。我有 9 个帖子,并使用“3”进行分页,因此有 3 页。一切正常,但 css 很糟糕。这是分页的图片。不是正确的页数。

因此,我要将 boostrap 4 css 添加到 CI 的分页中。当我添加 boostrap 4 的分页时,它只显示 1 页。 css 是 bs4 格式,但页面只显示“1”。这是一张照片:

这是我的控制器:

class Post extends BaseController
{

function __construct(){
    $this->PostModel        = new \App\Models\PostModel;    
    $this->CategoryModel    = new \App\Models\CategoryModel;
}

function index(){
    $post_category_id = null;
    $category_is_published = 1;
    $post_is_published = 1; 
    $pagination = 1;  // this is just to tell the model to return $this instead of the results.
    $this->data['posts']    = $this->PostModel->getPostsByCategory($post_category_id, 
                              $category_is_published, $post_is_published, $pagination )->paginate(3);
    $this->data['pager']    = $this->PostModel->pager;
    return view('Post/post_index', $this->data);
}

}//end controller

这是我的视图文件(当然,我已经缩短了它)。 $pager->links() 会显示正确的页数,但是当我添加 bootstrap 4 模板时,如下所示,它只显示一页。

<?php foreach ($posts as $post) :  ?>
    <p class="card-text"> <?php echo word_limiter($post->post_body, 30); ?></p>
<?php endforeach; ?>
<?= $pager->links('bootstrap', 'bootstrap4_pagination'); ?>

这是我的 bootstrap4_pagination 模板;

<?php $pager->setSurroundCount(4); ?>
<nav>
<ul class="pagination">
    <?php if ($pager->hasPrevious()) { ?>
        <li class="page-item">
             <a href="<?= $pager->getFirst() ?>" aria-label="First" class="page-link">
                <span aria-hidden="true">First</span>
            </a>
        </li>
        <li class="page-item">
            <a href="<?= $pager->getPrevious() ?>" class="page-link" aria-label="Previous">
                <span>&laquo;</span>
            </a>
        </li>
    <?php } ?>

    <?php 
        foreach ($pager->links() as $link) { 
            $activeclass = $link['active']?'active':'';
    ?>
        <li class="page-item <?= $activeclass ?>">
            <a href="<?= $link['uri'] ?>" class="page-link">
                <?= $link['title'] ?>
            </a>
        </li>
    <?php } ?>

    <?php if ($pager->hasNext()) { ?>
        <li class="page-item">
            <a href="<?= $pager->getNext() ?>" aria-label="Next" class="page-link">
                <span aria-hidden="true">&raquo;</span>
            </a>
        </li>
        <li class="page-item">
             <a href="<?= $pager->getLast() ?>" aria-label="Last" class="page-link">
                <span aria-hidden="true">Last</span>
            </a>
        </li>
    <?php } ?>
</ul>
</nav>

您已指定要使用 bootstrap 群组:

<?= $pager->links('bootstrap', 'bootstrap4_pagination'); ?>

但您没有创建 bootstrap 群组:

$this->data['posts'] = $this->PostModel->getPostsByCategory($post_category_id, $category_is_published, $post_is_published, $pagination )->paginate(3);

这应该是:

$this->data['posts'] = $this->PostModel->getPostsByCategory($post_category_id, $category_is_published, $post_is_published, $pagination )->paginate(3, 'bootstrap');

或者您可以省略组并将 bootstrap 替换为 default:

<?= $pager->links('default', 'bootstrap4_pagination'); ?>
