Question

城市显示在视图页面中，如 chennaihyderabadmumbai 。我需要展示 chennai，hyderabad，mumbai 。请帮助

控制器代码：

$data['jobCityName'] =explode(',',$viewData['jobCity']);
foreach($data['jobCityName'] as $cityid) {        
    $data['jobCityNames']=$this->hrm_model->getCitybyId($cityid);
    $data['jobCity'].=$data['jobCityNames']['cityName'];

型号代码

function getCitybyId($city)
    {
        $this->db->select('cityName');
        $this->db->from('city');
        $this->db->where("city_id", $city);
        $query = $this->db->get();
        return $query->row_array();
    }

Answer 1

希望这会对您有所帮助：

更改您的模型：

function getCitybyId($city)
{
    $this->db->select('cityName');
    $this->db->from('city');
    $this->db->where("city_id", $city);
    $query = $this->db->get();
    if ($query->num_rows() > 0 )
    {
       return $query->row()->cityName;
    }

}

在控制器

中

$data['jobCityName'] = explode(',',$viewData['jobCity']);
foreach($data['jobCityName'] as $cityid) {        
    /*$data['jobCityNames']=$this->hrm_model->getCitybyId($cityid);*/
    $data['jobCity'][] = $this->hrm_model->getCitybyId($cityid);
}
$data['jobCity'] = implode(',',$data['jobCity']);

对于单个城市使用此：

$data['single_city_name'] = $this->hrm_model->getCitybyId($cityid);

将其传递给视图：

$this->load->view('your_view',$data);

除第一项外，请在逗号旁边加上逗号：

$data['jobCityName'] =explode(',',$viewData['jobCity']);
$isFirst = true;
foreach($data['jobCityName'] as $cityid) {        
    $data['jobCityNames']=$this->hrm_model->getCitybyId($cityid);
    $data['jobCity'].=$data['jobCityNames']['cityName'].($isFirst ? "" : ",");
    $isFirst = false;
}
