codeigniterのドロップダウンとして多次元配列から返された値を出力しようとしています

Question

codeigniterビューでドロップダウンリストにfirstnameとlastnameを表示できません。今は空白のドロップダウンを表示しています。参照のために添付されたMVCコード。モデルは正しいデータを返しています。つまり、このprint_r（$ data ['groups']）を実行しようとしたときです。 ダイ;私のコントローラでは以下のように出力します

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)) 

私はドロップダウン値としてファーストネームとラストネームを印刷しようとしています。

マイビューコードは：

<select class="form-control" name="name"> 
 
<?php

マイコントローラコードがある：

Answer 1

変更

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($this->myTables['pr_users_details'].' as ud','ud.userid = g.userid'); 
      //$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; 




      } 

にあなたのコードは、ジャスト）（$リターン= $ query-> result_arrayを変更します。 $ return = $ query-> result（）;に戻ります。例えば

あなたがresult_arrayを（）を使用しているならば、インクルードは

結果については（）それは

$query = $this->db->query("YOUR QUERY"); 

foreach ($query->result() as $row) 
{ 
     echo $row->title; 
     echo $row->name; 
     echo $row->body; 
} 

Refrenceだろう

$query = $this->db->query("YOUR QUERY"); 

foreach ($query->result_array() as $row) 
{ 
     echo $row['title']; 
     echo $row['name']; 
     echo $row['body']; 
}

Answer 2

使用HTMLのselectタグの代わりにcodeigniterの組み込みドロップダウン関数。

<?php 
$attributes = 'class = "form-control" id = "group"'; 
echo form_dropdown('group',$group,set_value('firstname'),$attributes); 
?>
