在MySQL中，您不能将列命名为“组”，因为它是一个组。将列重命名为更符合您的代码的名称，如userGroup。正如@danfromdermany所指出的，转义数据库表列肯定有问题
class Db {
public function update($table, $id, $fields = array()) {
$set = '';
$x = 1;
foreach($fields as $name => $value) {
$set .= "`{$name}` = ?"; // Mind this row. ` were added to table column name.
if($x < count($fields)) {
$set .= ',';
}
$x++;
}
$sql = "UPDATE {$table} SET {$set} WHERE id = {$id}";
if(!$this->query($sql, $fields)->error()) {
return true;
}
return false;
}
}
classdb{
公共函数更新（$table，$id，$fields=array（））{
$set=''；
$x=1；
foreach（$name=>$value的字段）{
$set.=“`{$name}`=？”；//注意这一行。`已添加到表列名中。
如果（$x<计数（$fields））{
$set.='，'；
}
$x++；
}
$sql=“更新{$table}SET{$SET}，其中id={$id}”；
如果（！$this->query（$sql，$fields）->error（））{
返回true；
}
返回false；
}
}
你也应该仔细阅读。
它会报告那个错误
请投票@DanFromGermany的评论，如果这是真的，这个答案对你有帮助
顺便说一下：类名应该总是以大写字母开头。最好继续您是否收到任何错误消息？到目前为止，您尝试了什么？也许它不应该被称为group
，也许这与groupby
语句中的group
产生了冲突。顺便说一下，我没有得到反对票。当然有很多代码，但它有助于解决问题。但是，在问题发布之前，应该在开始时进行更多的调试。我知道这将是一件简单的事情。有趣的是，我的脚本寄存器部分与名为group的列配合得很好。谢谢你的帮助！！！
