if($_POST["submit3"])
{
$result=$connection->query("update t_user set f_username='$a', f_sex='$b',f_age='$c',f_CT='$d',f_zaoyingji='$f',f_buwei='$g',f_HU='$h',f_jishu='$i',f_xiaoaguo='$j',f_qianming='$k',f_yanchi_time='$l',f_chufa_time='$m'");

}
else {
echo "数据修改失败";
}
}
$result=$connection->query("select * from t_user where id=$id ");
while ($rws=$result->fetch_row()) {
?>
}
?>
if($_GET["type"]=="del"){
$id=$_GET["id"];
$result=$connection->query("delete from t_user where id in ($id)");
echo "<script>alert('删除成功!');window.location='index.php'</script>";
}
?>
------解决方案--------------------更新時需要加條件 where id='$id'
<br />$result=$connection->query("update t_user set f_username='$a', f_sex='$b',f_age='$c',f_CT='$d',f_zaoyingji='$f',f_buwei='$g',f_HU='$h',f_jishu='$i',f_xiaoaguo='$j',f_qianming='$k',f_yanchi_time='$l',f_chufa_time='$m' where id='$id'");<br />
