【问题描述】:
我在做一个文字类的网络游戏,在我的游戏里,有一个战斗系统。击败敌人后,如果您还没有徽章,您可以获得徽章。但是,由于一些我无法理解的奇怪原因,徽章按原样添加到数据库中(如果徽章的表行在 MySQL 数据库中不存在),但是应该伴随获得的文本徽章有时会出现。我会说回声显示 50% 或更少的时间。这是我的代码:
$gettrainerbadge = mysqli_query($conn, "SELECT * FROM t_badges where
badge='$badge' AND trainer='$getuser3[username]'");
$gettrainerbadge2 = mysqli_fetch_assoc($gettrainerbadge);
if(!$gettrainerbadge2)
{
//This echo shows up maybe 50% of the time the form is submitted.
echo "<font face='verdana' size='2'><br><br><br><img src='images/badges/$get_gym_leader3[badge].png' style='padding: 10px;'><br>By defeating $getuser3[battle_trainer] you have also earned a(n) $get_gym_leader3[badge] Badge!";
//This INSERT works as expected when the badge doesn't exist it adds the badge to the database if the badge already exists it does nothing
$addbadge = "INSERT INTO t_badges (`trainer`, `badge`) VALUES ('$getuser3[username]', '$get_gym_leader3[badge]')";
mysqli_query($conn, $addbadge);
}
正如我所说的 echo 语句有一半的时间都有效,它应该每次都有效,我无法弄清楚为什么要添加徽章,但伴随它的文本没有显示。任何帮助表示赞赏。
在玩了一些代码之后,我注意到有时我可以看到带有徽章图像的页面非常快速地闪烁,所以我不认为上面的代码是罪魁祸首。我认为这与我用来在没有用户反馈的情况下自动提交表单的以下脚本有关。我不知道他们为什么会互相干扰,但我几乎可以肯定在某处有一个双重帖子提交。如果有人能帮助指出我在这里可能做错了什么,我将不胜感激。
