PHP：插入多行到sql数据库

我想从我的表单插入多行数据到我的sql数据库。我一直在查找数组，并试图应用我发现的，但无济于事。我是编程的初学者，从来没有参加任何正式的课程，只是根据需要学习代码的片段，所以我的基础知识是不存在的。PHP：插入多行到sql数据库

PlayerID不是自动递增的，而是用户提供的实际数字。

这里是我的表单代码

你在混合MySQL API，他们不这样做;始终如一。 – 2014-08-28 02:17:25

您没有为相同字段发送多个值。你的姓名属性就像name="playerid"，这意味着每个具有相同名称的新条目都将覆盖前一个，并且只有一个被发送到服务器。

您应该使用阵列组的字段：

<input type="text" name="playerid[SOME_ID]" size="20"> 
... 
<input type="text" name="firstname[SOME_ID]" size="20"> 
... 
// etc. 

... 
<input type="text" name="playerid[SOME_OTHER_ID]" size="20"> 
... 
<input type="text" name="firstname[SOME_OTHER_ID]" size="20"> 
... 
// etc.

对于SOME_ID，SOME_OTHER_ID等值，你可以从数据库中，如果它已经存在，或者一个简单的计数器，只要使用一个值组中的字段使用相同的号码/ ID。

关于php方面，正如@ Fred-ii提到的那样，您应该只使用一个sql API，在这种情况下是mysqli。

还要注意的是：

$playerid = mysqli_real_escape_string('playerid');

应该是：

$playerid = mysqli_real_escape_string($con, 'playerid');

我个人也将使用与绑定变量的一份声明中，这样就可以一次准备语句，然后运行几次使用不同的值组而不必担心sql注入/转义值。

一个附加备注：

这是要失败的：

$row_data = "($playerid,$firstname, $lastname, $position,$team,$Game)"; 

if (is_array($row_data)); 
{

你刚才设置你的$row_data变量是一个字符串，可能与一堆不确定的变量，因此检查一行之后，这是否是一个数组永远不会工作。

也在3个地方。蠕虫陷阱。 – 2014-08-28 02:20:07

@ Fred-ii-我看到过更糟;-) – jeroen 2014-08-28 02:23:23

同样在这里。 'mysqli_real_escape_string（'playerid'）'我没有看到那个。 *然而，*我早些时候快速浏览了一下，看起来有些奇怪。 – 2014-08-28 02:23:36

好吧，自从最后一点以来已经有一段时间了，生活变得繁忙，我想做更多的研究。

我修改了我的form.html来指定它们是数组，并创建了一个新的php文件。这里是下面的代码。

      // $e = $team_a[$i]; 
      // $f = $game_a[$i]; 

        $str[ ] = "('{$player_[$i]}','{$firstname_[$i]}','{$lastname_[$i]}','{$position_[$i]}','{$team_[$i]}','{$game_[$i]}')"; 
      } 

      $s= implode(',', $str); 

      $sql="INSERT INTO wp_es_fstest (playerid, firstname, lastname, position, team, game) VALUES $s"; 

      echo $sql; 


      mysqli_close($con); 

      ?>

我不认为我正确定义的一切，在回声我是空值。

INSERT INTO wp_es_fstest (playerid, firstname, lastname, position, team, game) VALUES  ('','','','','',''),('','','','','',''),('','','','','',''),('','','','','',''),('','','','','',''), ('','','','','','')
