[英]SQL Query insert error
So I'm currently trying to establish a database connection to my server and my insertion is having some problems. 因此,我目前正在尝试与服务器建立数据库连接,而我的插入遇到了一些问题。 My query works when I manually try to plug it into phpmyadmin and a single row gets inserted.
当我手动尝试将其插入phpmyadmin并插入一行时,我的查询有效。
However, when I try to load a page with the below code, it seems to hit the database 3 times. 但是,当我尝试使用下面的代码加载页面时,似乎击中数据库3次。 I tried using exit() right after my query to see if there was any weird loops, but it still got entered 3 times into the database.
我尝试在查询后立即使用exit()来查看是否存在任何怪异的循环,但仍将其输入数据库3次。 Is there anything that seems weird here?
这里有什么奇怪的地方吗?
//timestamp
$t = time();
$stamp = date("Y-m-d", $t);
//create connection
$conn = new mysqli($servername, $username, $password, $dbname);
//check connection
if($conn->connect_error){
die("connection failed: ".$conn->connect_error);
}
echo "Connection Successful"."<br>";
$name = "hi";
$affiliation = "yo";
$note = "wat";
$sql = "INSERT INTO `$table` (`name`, `affiliation`, `notes`, `timestamp`) VALUES ('$name', '$affiliation', '$note', '$stamp')";
$result = $conn->query($sql);
if($result){
echo "Data entered successfully";
echo "<br>".$sql;
} else{
echo "Error: " .$sql."<br>".$conn->error;
}
$conn->close();

So here is a sample output for the whole table during one session 因此,这是一个会话期间整个表的示例输出
id: 281 - Name: yo wat 2016-09-03 19:18:09 id:281-名称:哟wat 2016-09-03 19:18:09
id: 282 - Name: yo wat 2016-09-03 19:18:11 id:282-名称:哟wat 2016-09-03 19:18:11
id: 283 - Name: yo wat 2016-09-03 19:18:11 id:283-名称:哟wat 2016-09-03 19:18:11
id: 284 - Name: yo wat 2016-09-03 19:20:55 id:284-名称:yo wat 2016-09-03 19:20:55
As you can tell by the timestamp, one gets added in one session and it is correct. 如您所知,在一个会话中添加了一个,这是正确的。 However, shortly after that one is added 2 more instances of the query are run and put in. So the reason I was seeing 3 outputs per refresh is because of the 2 extra inserts that get through.
但是,不久之后,又添加了2个查询实例,并将其放入。因此,我之所以看到每个刷新3个输出,是因为获得了2个额外的插入。 (The 2 extra + the 1 correct insert)
(额外2个+正确插入1个)
I'm mystified as to why it does this, because it seems to be a server-related issue. 我对为什么要这样做感到迷惑不解,因为这似乎是与服务器相关的问题。 I'm running mariadb and things look correct, but maybe something isn't closing correctly?
我正在运行mariadb,并且一切看起来正确,但是也许某些东西无法正确关闭?
I would like to know if someone knows a reason to why this happens, but for now, the immediate problem is solved. 我想知道是否有人知道发生这种情况的原因,但是现在,眼前的问题已经解决。
