如何使用代码点火器活动记录在 mysql 表的单个字段中搜索多个值 - How to search for multiple values in a single field of mysql table using codeigniter active record?

How to search for multiple values in a single field of mysql table using codeigniter active record?

我必须在codeigniter中使用mysql在一个字段中搜索多个值。下面是我的代码。

在控制器中

public function vpsearch()
{
  $data['info'] = $this->psearch_m->emp_search_form();
  $this->load->view("employer/result",$data);       
}

在模型中

public function emp_search_form()
{
  $skill = $this->security->xss_clean($this->input->post('ps_skills'));
  $jrole = $this->input->post('ps_jobrole'));

  if ( $jrole !== NULL) 
  {
    return $this->db->get('js_edu_details');
    $this->db->like('js_skills','$skill');
  }
}

在视图，即（./雇主/结果）

foreach($info->result() as $row)
{
  echo $row->js_id."<br/><br/>" ;
}

但是，我正在获取"js_edu_details"表中的所有记录，而不是搜索"技能"的字段。

我哪里出错了？任何帮助 wud b 感谢，提前感谢。

尝试：

public function emp_search_form()
{
    $skill = $this->security->xss_clean($this->input->post('ps_skills'));
    //$skill = $this->input->post('ps_skills', true);  other short way of getting the above result with `xss clean`
    if ( $jrole !== NULL) 
    {
        $this->db->like('js_skills',$skill); #remove the single quote around the `$skill`
        $res = $this->db->get('js_edu_details');
        echo $this->db->last_query(); #try to print the query generated
        return $res;
    }
}

Return语句应位于like语句之后

你应该像这样正确地排列代码

public function emp_search_form()
{
    $ps_skills  =   $this->input->post('ps_skills')
    $skill      = $this->security->xss_clean($ps_skills);
    if ( $jrole !== NULL) 
    {
        $this->db->like('js_skills','$skill');
        return $this->db->get('js_edu_details');
    }
}

另外，您应该注意条件永远不会满足。它总是会给出错误undefined variable $jrole
