Codeigniter数组显示

Question

我想显示数组的值，但它只显示数组的一个值而不是数组的所有值。

型号：

function get_subject_position($exam_id , $class_id , $subject_id) { 

     $this->db->where('exam_id' , $exam_id); 
     $this->db->where('class_id' , $class_id); 
     $this->db->where('subject_id' , $subject_id); 
     $this->db->select('mark_obtained'); 
     $this->db->order_by('mark_obtained DESC'); 
     $subject_position = $this->db->get('mark')->result_array(); 
     foreach($subject_position as $row) { 

      return $row;  
     } 
     } 

查看：

$subject_pos = $this->crud_model->get_subject_position($row2['exam_id'], $class_id, $row3['subject_id']); 

<td style="text-align: center;"><?php echo $subject_pos['mark_obtained'];?></td> 

Answer 1

您需要的 “foreach” 循环进入您的看法，因为现在它的返回首$行，然后停止在foreach环路（ “返回” 停止循环）

实施例：

查看

<?php 
$subject_pos = $this->crud_model->get_subject_position($row2['exam_id'], $class_id, $row3['subject_id']); 
foreach($subject_pos as $row) { 
?> 
<tr> 
    <td style="text-align: center;"><?=$row['mark_obtained']?></td> 
</tr> 
<?php } ?> 

功能

function get_subject_position($exam_id , $class_id , $subject_id) { 

    $this->db->where('exam_id' , $exam_id); 
    $this->db->where('class_id' , $class_id); 
    $this->db->where('subject_id' , $subject_id); 
    $this->db->select('mark_obtained'); 
    $this->db->order_by('mark_obtained DESC'); 

    return $this->db->get('mark')->result_array(); // Get ALL rows 

    }
