如何将会话用户名插入 mySql 数据库

Question

我正在尝试编写一个程序，用户可以在其中将数据添加到数据库中，并且还无需手动输入用户的用户名。这是php代码

$user->createSession(array(
             'title' => Input::get('title'),
             'start_date' => date('Y-m-d H:i:s', strtotime(Input::get('start_date'))),
             'end_date' => date('Y-m-d H:i:s', strtotime(Input::get('end_date'))),
             'passcode' => (Input::get('passcode')),
             'username' => (Input::get('username'))
         ));

这是 html

<form class="session" action="" method="POST" >
  <div class="input-group">

<label for="title" ><span class="input-group-addon" id="basic-addon1">Title</span></label>

<input type="text" id="username" name="title" class="form-control" value = "<?php echo escape(input::get('title')); ?>" placeholder="Title" autocomplete="on" required> 
  </div>

<div id="datetimepicker" class="input-append date">
    <input type="text" name="start_date" placeholder="start date"></input>

  <span class="add-on">
    <i data-time-icon="icon-time" data-date-icon="icon-calendar"></i>
  </span>
</div>

<div id="datetimepicker1" class="input-append date">
    <input type="text" name="end_date" placeholder="end date"></input>
  <span class="add-on">
    <i data-time-icon="icon-time" data-date-icon="icon-calendar"></i>
  </span>
</div>

  <label for="passcode" class="input-group">Pass-code (optional)</label>
    <input type="passcode" id="passcode" name="passcode" class="form-control" placeholder="Passcode" autocomplete="off" >

    <br>
    <input type = "hidden" name = "username" value = "<?php echo escape($user->data()->username); ?>">

<button class="btn btn-lg btn-primary" type="submit">Create</button>

它将除用户名会话之外的所有内容添加到数据库中。我不知道该怎么办。我也试过删除：

<input type = "hidden" name = "username" value = "<?php echo escape($user->data()->username); ?>">

并且做了：

$user->createSession(array(
         'title' => Input::get('title'),
         'start_date' => date('Y-m-d H:i:s', strtotime(Input::get('start_date'))),
         'end_date' => date('Y-m-d H:i:s', strtotime(Input::get('end_date'))),
         'passcode' => (Input::get('passcode')),
         'username' => $user->data()->username
     ));

这是请求的数据库代码

session_start();

$GLOBALS['config'] = array(
    'mysql'     => array(
    'host'      => 'localhost', 
    'username'  => 'root', 
    'password'  => '', 
    'db' => 'coursework'),
        //remember me
    'remember' => array('cookie_name' => 'hash', 'cookie_expiry' => '604800'),

'session' => array('session_name' => 'user', 'token_name' => 'token'));

spl_autoload_register(function($class) {
    require_once 'classes/'.$class.'.php';
});

编辑

此代码将数据插入数据库

 public function createSession($fields = array()){
    if(!$this->_db->insert('sessions', $fields)){
        throw new Exception ("there was a problem adding a session");
    }
}

其他一切正常，数据库连接正常，数据输入数据库正常，但用户名字段为空。正在创建的会话是其他类似主题的东西。

连接到数据库

function __construct() {
    try {
        $this->_pdo = new PDO('mysql:host=' . Config::get('mysql/host') .';dbname=' . Config::get('mysql/db'), Config::get('mysql/username'), Config::get('mysql/password'));
        //echo 'connected';
    } catch (PDOException $e) {
        die($e->getMessage());
    }

}

How to insert session username into mySql database

您需要 connect 使用您的配置信息到实际数据库。

PDO 很适合这个：

 $dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

你需要insert into the database, preferrably using prepared statements.

有很多 decent answers on how although I like mixing it up with the prepared statement article，您应该在准备好的查询中执行变量数组。

获取会话信息

你大概能想出怎么做。也许还有一些其他信息？

$someValue = ""; // Just some random value.
$someSessionValue = ""; // Extract from session. Probably $_SESSION['stuff'] or similar.

最后，插入提取的信息。

应该这样做，仔细查看链接或进行适当的搜索：

$sql = $dbh->prepare("INSERT INTO tablename(column1, column2) VALUES (?, ?)");
$sql->execute(array($someValue, $someSessionValue));

如果您希望它自动发生，那么您只需将它放入一个方法中，当某些操作被触发时，您的代码将自动调用。
