我无法使用从剥离RSS提要中的链接获得的ID来获取每个帖子的正确字段值。
MyBB rss提要未在rss提要中提供作者值，因此我使用包含线程ID的提要中的链接手动获取了该值。我认为我可以从链接中成功获取正确的线程ID，因为我可以在每个帖子中回显正确的线程ID。因此，在获取数据库中的作者字段（用户名）时，我对线程ID使用相同的变量。我正在获取用户名字段，但所有帖子都显示相同的内容，它实际上是最后发布的用户名。我能够使它正常工作，并找到合适的作者，但是由于生活中有些疯狂的事情，而且我确实是该领域的新手，所以我无法备份并忘记了我是怎么做到的。
这是我用来从Feed中发布帖子的代码：
<?php
//Getting RSS Feed
$rss = new DOMDocument();
$rss->load('https://www.cmricths.com/board/syndication.php?fid=2');
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('encoded')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
//Setting Feed Limits
$fid = 2;
$limit = 5;
require_once 'queries/threadcount.php';
if ($tcount > $limit) {
$tlimit = $limit;
} else {
$tlimit = $tcount;
}
//Posting the feed
for($x=0;$x<$tlimit;$x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$date = date('l F d, Y', strtotime($feed[$x]['date']));
//getting thread id from the link
$arr = explode('=', $link);
$tid = $arr[1];
//fetching the author
require_once 'queries/postedby.php';
//post summary
echo '<h2 class="blog-post-title">'.$title.'</h2>';
echo '<p class="blog-post-meta">'.$date.' <em>by: '.$author.' '.$tid.'</em></p>';
echo '<p class="mb-0">'.$description.'</p>';
echo '<hr />';
}
?>
这是获取作者的代码：
<?php
/*
References:
*jQuery Remote Validation
*https://websitebeaver.com/prepared-statements-in-php-mysqli-to-prevent-sql-injection
*/
// Get Connection Details
require_once 'config.php';
// Setup the connection
$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
if($mysqli->connect_error) {
echo json_encode('Error connecting to database!');
exit;
} else {
// Do the validation process
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli->set_charset("utf8mb4");
//Prepare the statement
$stmt = $mysqli->prepare("SELECT `username` FROM `mybb_posts` WHERE `tid` = ?");
//Bind the parameter
$stmt->bind_param("i", $tid);
//Execute the statement
$stmt->execute();
//Get the result
$result = $stmt->get_result();
//Fetch Data
$row = $result->fetch_array();
$author = $row['username'];
}
?>
这是我的sql数据文件：

我想为每个线程获取正确的作者。因此，如果线程ID为9，我应该以jodilljames.esteban作为作者；如果线程ID为10，我应该以hermes.vargas作为作者，依此类推...
答案 0 :(得分：0)
如果您从queries/postedby.php脚本中提取了一些代码并将其放在代码的开头，请在开始任何循环之前创建prepared statement，然后可能会发现类似以下方法的方法
那让我感到惊讶，PHPBB不允许编辑RSS到您可以选择添加到提要中的程度……也许可以-也许不能-自从我看过已经有好几年了该软件。
祝你好运，希望能有所帮助
