我想顯示另一個(gè)表中的數(shù)據(jù)。這是CodeIgniter框架。我嘗試了很多代碼，但它們不起作用。這是我的代碼：<?phpforeach ($users->result_array() as $key => $user): ?> <tr> <td> <?php echo $key+1; ?></td> <td> <img src="<?php echo $this->user_model->get_user_image_url($user['id']);?>" alt="" height="50" width="50" class="img-fluid rounded-circle img-thumbnail"> </td> <td> <?php echo $user['first_name'].' '.$user['last_name']; ?> <?php if($user['status'] != 1): ?> <small><p><?php echo get_phrase('status'); ?>: <span class="badge badge-danger-lighten"><?php echo get_phrase('unverified'); ?></span></p></small> <?php endif; ?> </td> <td> <?php echo $user['email']; ?> </td> <td> <?php echo $user['classcategory_id']; ?> </td> <td> <?php $enrolled_courses = $this->crud_model->enrol_history_by_user_id($user['id']);?> <ul> <?php foreach ($enrolled_courses->result_array() as $enrolled_course): $course_details = $this->crud_model->get_course_by_id($enrolled_course['course_id'])->row_array();?> <li><?php echo $course_details['title']; ?></li> <?php endforeach; ?> </ul> </td>我怎樣才能改變這個(gè) <td> <?php echo $user['classcategory_id']; ?> </td>從表名稱“classcategory”字段“name”中獲取數(shù)據(jù)我的控制器，用于用戶和課程public function get_courses() { if ($this->session->userdata('admin_login') != true) { redirect(site_url('login'), 'refresh'); }...我的數(shù)據(jù)庫就像這個(gè)表 - > CLASSCATEGORY：列：ID +名稱表 - > USER：列：ID + classcategory_id

您可以使用 CLASSCATEGORY 和 SELECT CLASSCATEGORY.name AS 類別名稱 JOIN 模型中的 USER 表，然后echo $user['categoryname']. 以下是如何在 CodeIgniter 中連接兩個(gè)表的示例
$this->db->select('USER.*, CLASSCATEGORY.name AS categoryname')
->from('users')
->join('CLASSCATEGORY', 'CLASSCATEGORY.id = USER.classcategory_id')
->get()
->result();

public function getallRecords($id,$product_id)
{
$this->db->select('*');
$this->db->from('products');
$this->db->where('id', $id);
$this->db->where('product_id', $product_id);
$this->db->where('show', 'no');
$this->db->where('Results !=', '0');
$this->db->order_by('added', 'DESC');
$this->db->limit(30);
$getallRecords=$this->db->get();
$resultllRecords=$getallRecords->result();
return $resultllRecords;
}
