Php 无法检索结果数据
我试图通过查询检索一组行。但是,当我试图检索Php 无法检索结果数据,php,codeigniter,Php,Codeigniter,我试图通过查询检索一组行。但是,当我试图检索$query->result()时,无法检索结果集 使用print\r($query),我得到以下结果: object(CI_DB_mysql_result)#22 (8) { ["conn_id"]=> resource(61) of type (mysql link persistent) ["result_id"]=> resource(82) of type (mysql result) ["result_array"
$query->result()
时,无法检索结果集
使用print\r($query)
,我得到以下结果:
object(CI_DB_mysql_result)#22 (8) {
["conn_id"]=> resource(61) of type (mysql link persistent)
["result_id"]=> resource(82) of type (mysql result)
["result_array"]=> array(0) { } ["result_object"]=> array(0) { }
["custom_result_object"]=> array(0) { }
["current_row"]=> int(0)
["num_rows"]=> int(8)
["row_data"]=> NULL
}
该表包含数据且不为空。代码中正确指定了所有参数和名称
我的代码如下:
型号:
function site_detail( $vendor_id, $city, $restict_year, $type, $total_length, $adult, $children,$pets ) {
$this->db->select('*');
$this->db->from('vendor_details');
$this->db->join('vendor_siteinfo', 'vendor_siteinfo.vendor_id = vendor_details.id', 'left');
$this->db->join('vendorstay_details', 'vendorstay_details.vendor_id=vendor_details.id');
$this->db->where('city',$city);
$this->db->where('year_restrict',$restict_year);
$this->db->where('site_type',$type);
$this->db->where('site_length',$total_length);
$this->db->where('adult_limit',$adult);
$this->db->where('child_limit',$children);
$this->db->where('pet_limit',$pets);
$query = $this->db->get();
$total=$query->num_rows();
if($total != 0)
{
// echo "Search details found !!!";
// echo "TOTAL"; echo "$total";
return $query->result_array();
}
elseif($total= 0)
{
//echo "No results!";
return false;
}
print_r($query);
}
控制器:
function search_detail($vendor_id, $city, $restict_year, $type, $total_length, $adult, $children, $pets) {
$data['site']=$this->Home_Model->site_detail($vendor_id,$city,$restict_year,$type,$total_length,$adult,$children,$pets);
// $data['site_detail']=$this->Home_Model->sample($vendor_id);
//echo "site=$site";
print_r($data);
$this->load->view("search_detail",$data);
}
视图:
要检索
$query
,您需要执行以下操作:
// for object
foreach($query->result() as $row)
{
echo $row->your_table_field_name;
}
或
我也有同样的问题和你的建议
$result = $this->db->get()->result_array();
为我工作。
但我很好奇,为什么我的原始代码突然停止工作,所有的变化都是我的服务器
$this->db->select('*');
$this->db->from('isl_user');
$this->db->order_by('isl_user.name','asc');
$query = $this->db->get();
return $query;
你能提供完整的代码(包括查询本身)吗?
$result = $this->db->get()->result_array();
$this->db->select('*');
$this->db->from('isl_user');
$this->db->order_by('isl_user.name','asc');
$query = $this->db->get();
return $query;
