如何在 Codeigniter 中获取特定的行数据

Question

我的 CodeIgniter 视图中有一张 bootstrap 卡片，其中包含阅读更多选项。单击按钮时，url 显示所选的卡 ID，但仅从数据库中提取第一行。不确定，我哪里做错了。

控制器代码从这里开始

public function getDetails()
{
        $query = $this->db->query("SELECT swo_brief_intro, swo_image_heading FROM services_offered");

        $row = $query->row();

        if (isset($row))
        {
                echo $row->swo_image_heading;
                echo $row->swo_brief_intro;
        }

        
}

视图代码从这里开始

<div class="row clearfix">

<?php 
    $query = $this->db->query("SELECT * FROM services_offered LIMIT 15");
    foreach ($query->result() as $row) {
        echo "<div class='col-lg-4 bottommargin-sm'>";
        echo "<div class='feature-box media-box fbox-bg'>";
        echo "<div class='fbox-media'>";
        echo "<a href='#'><img src='$row->swo_images' alt='Featured Box Image' style='height:250px; width:450px;'></a></div>";
        echo "<div class='fbox-content fbox-content-lg'>";
        $string = $row->swo_brief_intro;
        $string = word_limiter($string, 15);
        echo "<h3 class='nott ls0 font-weight-semibold'>$row->swo_image_heading<span class='subtitle font-secondary font-weight-light ls0'>$string</span></h3>";
        echo "<a href='Fetch/getDetails/{$row->id}' class='button-link border-0 color btn-edit'>Read More</a>";
        echo "</div>";
        echo "</div>";
        echo "</div>";


    }
?>

请协助。谢谢

Answer 1

a) 您忘记在函数中添加 Id 参数。

b) 以及忘记基于此更改查询。

public function getDetails($id)
{

    $row = $this 
            -> db
            -> select('swo_brief_intro, swo_image_heading')
            -> where('<put here id column name>', $id)
            -> limit(1)
            -> get('services_offered')
            -> row();
    
    if (isset($row))
    {
        echo $row->swo_image_heading;
        echo $row->swo_brief_intro;
    }
        
}
