Mysql Codeigniter数据库问题
从我的数据库中获取一些数据有点麻烦 我有以下型号:Mysql Codeigniter数据库问题,mysql,database,codeigniter,Mysql,Database,Codeigniter,从我的数据库中获取一些数据有点麻烦 我有以下型号: function GetRestaurants($options = array()) { // Qualification if(isset($options['restaurantID'])) $this->db->where('restaurantID', $options['restaurantID']); if(isset($options['
function GetRestaurants($options = array())
{
// Qualification
if(isset($options['restaurantID']))
$this->db->where('restaurantID', $options['restaurantID']);
if(isset($options['restaurantRegionID']))
$this->db->where('restaurantRegionID', $options['restaurantRegionID']);
if(isset($options['restaurantName']))
$this->db->where('restaurantName', $options['restaurantName']);
if(isset($options['restaurantAddress1']))
$this->db->where('restaurantAddress1', $options['restaurantAddress1']);
if(isset($options['restaurantAddress2']))
$this->db->where('restaurantAddress2', $options['restaurantAddress2']);
if(isset($options['restaurantSuburb']))
$this->db->where('restaurantSuburb', $options['restaurantSuburb']);
if(isset($options['restaurantCity']))
$this->db->where('restaurantCity', $options['restaurantCity']);
if(isset($options['restaurantInformation']))
$this->db->where('restaurantInformation', $options['restaurantInformation']);
// limit / offset
if(isset($options['limit']) && isset($options['offset']))
$this->db->limit($options['limit'], $options['offset']);
else if(isset($options['limit']))
$this->db->limit($options['limit']);
// sort
if(isset($options['sortBy']) && isset($options['sortDirection']))
$this->db->order_by($options['sortBy'], $options['sortDirection']);
$query = $this->db->get("tblRestaurants");
if(isset($options['count'])) return $query->num_rows();
if(isset($options['restaurantID']))
return $query->row(0);
if(isset($options['limit']) && $options['limit'] == '1')
return $query->row(0);
return $query->result();
}
现在,以下代码可以正常工作:
$this->load->model('Restaurants_model');
$data['restaurant'] = $this->Restaurants_model->GetRestaurants(array(
'restaurantName' => 'shed 5',
'limit' => '1'
));
但是,以下情况不起作用:
$this->load->model('Restaurants_model');
$data['restaurant'] = $this->Restaurants_model->GetRestaurants(array(
'restaurantName' => str_replace('-', ' ', $this->uri->segment(2)),
'limit' => '1'
));
即使
str_replace('-', ' ', $this->uri->segment(2))
在本例中为:“shed 5”
我比较了str_replace输出的var_转储和字符串本身,并确定它们是相同的。那么,为什么直接字符串返回结果,而从uri段生成的字符串却不返回结果呢?某种编码问题?我的数据库将数据保存在“utf8\u general\u ci”中
谢谢你的建议 $restaurant=str_替换“-”,“$this->uri->segment2 获取数组外部的值并尝试数组\u推送 $data['restaurant']=$this->Restaurants\u model->GetRestaurantsarray “restaurantName”=>$restaurant, “限制”=>“1”
; 看看echo$this->db->last\u查询的输出有什么不同。这在大多数情况下有助于解决查询问题。在$query=$this->db->gettbl之后将其插入模型中;
