[英]how to make laravel query builder like codeigniter active record
我有Laravel 4查詢構建器的問題,我想制作一個可重用的方法
public function getData($where=array())
{
// $where = array('city' => 'jakarta', 'age' => '25');
return User::where($where)->get();
// this will produce an error, because i think laravel didn't support it
}
在CodeIgniter中,將數組傳遞給活動記錄很容易:
public function getData($where=array())
{
$rs = $this->db->where($where)->from('user')->get();
return $rs->result();
}
// it will produce :
// SELECT * FROM user WHERE city = 'jakarta' AND age = '25'
知道如何在Laravel 4查詢構建器上使用它嗎? 我有谷歌搜索但沒有找到任何答案。 謝謝你。
您可以嘗試這個(假設,此功能在您的User
模型中)
class User extends Eloquent {
public static function getData($where = null)
{
$query = DB::table('User');
if(!is_null($where )) {
foreach($where as $k => $v){
$query->where($k, $v);
}
}
return $query->get();
}
}
Rember that, =
是可選的。 稱之為
$data = User::getData(array('first_name' => 'Jhon'));
$where[] = array(
'field' => 'city',
'operator' => '=',
'value' => 'jakarta'
);
$where[] = array(
'field' => 'age',
'operator' => '=',
'value' => 25
);
$data = getData($where);
public function getData($wheres = array()){
$query = User::query();
if(!empty($wheres)){
foreach($wheres as $where){
{
$query = $query->where($where['field'], $where['operator'], $where['value']);
}
$result = $query->get();
}
}
