php – MySQL bind_param将NULL写入表

导读:问题:尽管我的$settings数组中包含值(int),但当值为0和2时,MySQL会将NULL写入表中. 作为参考,$settings数组中的每个索引都是[0] = max和[1] = min的数组. public function updateAdaptiveArmour($gameid,$shipid,$settings){ foreach ($settings as $key =
问题:尽管我的$settings数组中包含值(int),但当值为0和2时,MySQL会将NULL写入表中.
作为参考,$settings数组中的每个索引都是[0] = max和[1] = min的数组. public function updateAdaptiveArmour($gameid,$shipid,$settings){ foreach ($settings as $key => $value){ debug::log($key." ".$value[0]." ".$value[1]); //just to show the contents // [561103190304f][2015-10-04 12:44:41] particle 4 2 // [56110319035b3][2015-10-04 12:44:41] laser 0 0 // [56110319035b3][2015-10-04 12:44:41] molecular 0 0 } try { if ($stmt = $this->connection->prepare( "UPDATE tac_adaptivearmour SET particlealloc = ?,laseralloc = ?,molecularalloc = ? WHERE gameid = ? AND shipid = ? " )) { $stmt->bind_param('iiiii',$settings[0][1],$settings[1][1],$settings[2][1],$gameid,$shipid); $stmt->execute(); $stmt->close(); } } catch(Exception $e) { throw $e; } } 理想情况下,对于此示例,我希望UPDATE为2/0/0而不是null / null / null. 解决方法
您的数组填充如下:
$settings = [ 'particle' => [4,2],'laser' => [0,0],'molecular' => [0,0] ]; 我希望能回答这个问题,而无需进一步解释. 它将固定如下: $stmt->bind_param('iiiii',$settings['particle'][1],$settings['laser'][1],$settings['molecular'][1],$shipid ); (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
