Question

我的控制器

$data['judul'] = $this->pengumuman->getJudul($id_announcement);

我的模特

public function getJudul($id_announcement)
    {
        $this->db->select('mp.id_announcement, mp.title_announcement, mp.isi_pengumuman')
        ->from('tbl_mst_pengumuman mp')
        ->order_by('mp.id_announcement','DESC' ,$id_announcement)
        ->limit(3);
        return $this->db->get()->row();
    }

我的观点

<div class="portlet-body">
        <div id="nt-example1-container">
          <ul id="nt-example1" class="news">
            <li>
                <b><a href="<?= site_url('login/pengumuman/detail/'.@$judul->id_announcement); ?>" class="link_pengumuman"><?= $judul->title_announcement ?></a></b>
                <?= $judul->isi_pengumuman ?>
                <li><br>
                <b><a href="<?= site_url('login/pengumuman/detail/'.@$judul->id_announcement); ?>" class="link_pengumuman"><?= $judul->title_announcement ?></a></b>
                <?= $judul->isi_pengumuman ?>
                </li><br>
                 <li>
                <b><a href="<?= site_url('login/pengumuman/detail/'.@$judul->id_announcement); ?>" class="link_pengumuman"><?= $judul->title_announcement ?></a></b>
                <?= $judul->isi_pengumuman ?>
                </li> <br>
                <li>
                <b><a href="<?= site_url('login/pengumuman/detail/'.@$judul->id_announcement); ?>" class="link_pengumuman"><?= $judul->title_announcement ?></a></b>
                <?= $judul->isi_pengumuman ?>
                </li><br>
              </div>
            </div>

注意：在我试图展示的视图上。我不知道语法是否错误。

Answer 1

<ul>
foreach($results as $value) {
    echo "<li>";
    // your code
    echo "</li>";
}
</ul>

不要在每个li之间使用br，而是使用css。

Answer 2

你正在使用$this->db->get()->row()函数，它只返回1行，你应该$this->db->get()->result()

另外，您在$id_announcement内传递了order_by()，这是错误的，我认为$id_announcement将id用id_announcement过滤结果public function getJudul($id_announcement) { $this->db->select('mp.id_announcement, mp.title_announcement, mp.isi_pengumuman') ->from('tbl_mst_pengumuman mp') ->where('mp.id_announcement', $id_announcement) ->limit(3) ->order_by('mp.id_announcement','DESC'); $query = $this->db->get(); return ($query->num_rows() > 0) ? $query->result() : false; } 1}}

所以，你的模型函数应该如下所示

<?php if($judul){ ?>
<div class="portlet-body">
    <div id="nt-example1-container">    
        <ul id="nt-example1" class="news">
        <?php foreach($judul as $row){ ?>
            <li>
                <b><a href="<?= site_url('login/pengumuman/detail/'.$row->id_announcement); ?>" class="link_pengumuman"><?= $row->title_announcement; ?></a></b>
                <?= $row->isi_pengumuman; ?>
            </li>   
        <?php } ?>          
        </ul>
    </div>
</div>
<?php }else{ echo 'no records found!'; } ?>

在视图文件中添加如下

<img src="cid:yourcontentid" />

我有4个title_announcement。但只出现一个title_announcement。如何让所有的标题出现？
