thinkphp数据库操作

$aCouseIds = $_POST['courseId'];

foreach($aCouseIds as $couseId ){
$sCouseIds .=  $couseId.',';
}
echo $sCouseIds;
$sCouseIds = addslashes($sCouseIds);
// $sql = "update cms_settings set value1 = '".$sCouseIds."' where name='home_gezkqbz' ";
$map['name'] = 'home_gezkqbz';
// $data ['value1'] = $sCouseIds;

$settings = M('Settings');
$data = array();
$data['value1']=$sCouseIds;
$r = $settings->where( 'name="home_gezkqbz"' )->save($data);
// $r = $settings->select();
// $Model = M();
// $r = $Model->query( $sql );
// $r = $settings->query($sql);
print_r ( $r);

用sql的时候要记得值要转意$sCouseIds。

$sql = "update cms_settings set value1 = '".$sCouseIds."' where name='home_gezkqbz' ";

加分号。
