尝试打印从多维数组返回的值作为 codeigniter 中的下拉列表
Trying to print values returned from multidimentional array as dropdown in codeigniter
无法在 codeigniter 视图中将名字和姓氏显示为下拉列表。现在它显示空白下拉列表。附上MVC代码供参考。模型正在返回正确的数据，即当我尝试这样做时 print_r($data['groups']);
死;在我的控制器中它给出如下输出
Array ( [0] => Array ( [id] => 62 [userid] => 67 [emp_code] => 050 [emp_shift] => General Shift [emp_category] => Full Time [cccode] => [prefix] => Mr. [firstname] => Divya [middlename] => [lastname] => Darshini [designation_id] => 9 [division_id] => [branch_id] => 5 [company] => [email] => shashankbhat11@gmail.com [personal_email] => [nickname] => [url] => [birthday] => 23-09-1990 [panno] => [passportno] => [passportdate] => [joining_date] => 08-07-2016 [resignation_date] => [team_id] => [tag_ids] => [im] => [facebook] => [twitter_handle] => [linkedin_id] => [instagram] => [googleplus] => [maidenname] => [profileimage] => [blood_group] => B Positive [gender] => Female [married] => [anniversary] => 01-01-1970 [ctc] => [mood] => [doc_type] => [org_to] => [org_from] => [org] => [role_title] => [org_skills] => [scanned_doc_work] => [pass_year] => [adm_year] => [degree] => [univ] => [edu_scanned_doc] => [declare_home] => [declare_menu1] => [declare_family] => [declare_menu4] => [declare_menu7] => [declare_menu8] => [declare_menu2] => [declare_menu3] => [s_cluster_id] => 1 [status] => 1 [deleted] => 0 [registrationtime] => 1466579573 [timemodified] => 0 [modifierid] => 0 [alternate_email] => [notice_period] => 0 ) )

将您的代码更改为
function get_all_names_by_user($USER){
$this->db->select('g.*,firstname,lastname');
$this->db->from('pr_users_details as g');
$this->db->where('userid', $USER->id);

//$this->db->join('pr_users_details as ud','ud.userid = g.userids');
/* $this->db->join($this->myTables['users_details'].' as ud','ud.userid = g.userid');
$this->db->join('pr_resignation_type as gt','gt.id = g.sr_type');*/
$query=$this->db->get();
$return = $query->result();
return $return;
}
只需更改 $return = $query->result_array();到 $return = $query->result();
例如，如果您使用的是 result_array()，那么就像
$query = $this->db->query("YOUR QUERY");
foreach ($query->result_array() as $row)
{
echo $row['title'];
echo $row['name'];
echo $row['body'];
}
result() 应该是
$query = $this->db->query("YOUR QUERY");
foreach ($query->result() as $row)
{
echo $row->title;
echo $row->name;
echo $row->body;
}
