只显示带有foreach限制的值的字段

Question

我有db结构

id | ref_id |美化1 |舒适2 |舒适3 |舒适4 |舒适5

每个舒适性列的值为1或0. 当进行搜索时，我需要显示值不等于零（值！= 0）的字段。 我知道我可以考虑这样做，因为

if($data->amenity1 == 0) echo ''; 

但我需要用它来限制自动化。

我的模型代码是

function select_all_active_amenities($for_id){ 
    foreach($for_id as $id){ 
     $prop_id = $id->vbc_item_id; 
    } 
    $this->db->select('*'); 
    $this->db->from('vbc_property_amenities'); 
    $this->db->where_in(array('v_ref_id'=> $prop_id)); 
    $this->db->limit(5); 
    $query = $this->db->get(); 
    $result = $query->result(); 

    return $result; 
} 

请帮

你只是使用自定义数组建立

function select_all_active_amenities($for_id){ 
foreach($for_id as $id){ 
    $prop_id = $id->vbc_item_id; 
} 
$this->db->select('*'); 
$this->db->distinct('v_ref_id'); 
$this->db->from('vbc_property_amenities'); 
$this->db->where_in(array('v_ref_id'=> $prop_id)); 
// $this->db->limit(5); 
$query = $this->db->get(); 
$result1 = $query->result_array(); 

//fetch the value as array 

//and this query for fetch the column name what you have right now an where not equal to id and ref_id 

$this->db->query("SELECT COLUMN_NAME FROM information_schema.COLUMNS WHERE TABLE_NAME='vbc_property_amenities' AND COLUMN_NAME !='id' AND COLUMN_NAME != 'ref_id AND COLUMN_NAME !='id' ")->result_array(); 
    $query = $this->db->get(); 
    $result2 = $query->result_array(); 

foreach($result as $key1=>$row1) 
{ 

     foreach($result2 as $key2=>$row2) 
     { 

      if($row2 ==$row1[$row2] && $row1 ==0) 
      { 

       unset($result[$key1][$row2]); 
      } 

     } 



} 

//$result only have the where value=1 

return $result; 

//you just limit the five in your view page 
}

添加“DISTINCT”关键字查询选择之前，获得唯一的记录

$this->db->distinct(); 

希望它可以帮助你出来了！
