Question

我从我的Twitter帐户中检索了直接消息，并且我希望将发件人，发件人屏幕名称和文本存储在mysql数据库表中，以便由Artificial intellingece标记语言引擎读取，以便它可以相应地进行回复。执行程序后，我检查了数据库，没有从数组输入任何行，也没有错误消息。

这是我的代码：

$connection = new TwitterOAuth($consumer_key,$consumer_secret, $oAuthToken, $oAuthSecret);

// Get direct message data 
$content = $connection ->get('https://api.twitter.com/1/direct_messages.json');

echo '<pre>',print_r($content,true),'</pre>';

function write_messages_to_database() {

require_once('connect_to_database');

$conn = mysql_connect("127.0.0.1", "Diego", "frafra") or die(mysql_error());
mysql_select_db('bot', $conn) or die(mysql_error());

foreach ($content as $directmessage) {
   mysql_query("INSERT INTO 'twitter_senders' ('sender_id', 'sender_name'), VALUES ('{$content->id}', '{$content->sender_screen_name}')");
   $directmessage_id = mysql_last_insert_id();
   foreach ($directmessage->text as $text) {
        mysql_query("INSERT INTO 'message_senders' ('message'), VALUES ('{$text->text}')");
   } 

 }
}

下面是我想从中提取id，sender_screen_name中的值的数组和text。此外，该数组有三个对象，但我只是粘贴在一个例子中。

您怎么看？

Answer 1

你有没有打电话给你write_messages_to_database()功能？

无论如何，我建议您按照以下几行重新定义：

function write_messages_to_database($content) {
    // Use PDO - it'll make your life so much easier
    $dbh = new PDO('mysql:dbname=bot;host=127.0.0.1', "Diego", "frafra");

    // use prepared statements to prevent SQL injection
    // see http://bobby-tables.com for more info
    // great thing is, we can prepare once and use many!
    $sender_stmt = $dbh->prepare("
        INSERT INTO twitter_senders (sender_id, sender_name)
        VALUES (:id, :name)
    ");
    $sender_stmt->bindParam(":id"  , $sender_id  );
    $sender_stmt->bindParam(":name", $sender_name);

    $message_stmt = $dbh->prepare("
        INSERT INTO message_senders (message) VALUES (:text)
    ");
    $message_stmt->bindParam(":text", $text);

    foreach ($content as $directmessage) {
       $sender_id   = $directmessage->sender->id  ;
       $sender_name = $directmessage->sender->name;
       $sender_stmt->execute();

       // this is pointless...
       $directmessage_id = $dbh->lastInsertId();

       $text = $directmessage->text;
       $message_stmt->execute();
    }
}

Answer 2

除非我们知道错误是什么，否则无法帮助您。

尝试这样做：

foreach ($directmessage->text as $text) {
        mysql_query("INSERT INTO 'message_senders' ('message'), VALUES ('{$text->text}')") 
        or die(mysql_error());
       }

此外，更好的方法是：

foreach ($directmessage->text as $text) {
    $query = sprintf("INSERT INTO 'message_senders' ('message'), VALUES ('%s')"
                , mysql_real_escape_string($text->text));
    mysql_query($query) or die(mysql_error());
}

将数组值写入mysql数据库
