我目前正在開發討論板。我的問題是，它似乎是它給每個類別的4 ID，然後顯示在4類論壇（那不是很好的解釋，但希望你明白）...PHP MySQL創建討論板
<?php
/* CATEGORIES */
$query = "SELECT * FROM bkg_categories";
try {
$stmt = $db->prepare($query);
$result = $stmt->execute();
} catch(PDOException $e) {
$error[] = "An error has occured. Please try again later.";
}
$categories = $stmt->fetchAll();
/* FORUMS */
foreach($categories as $category) {
$catid = $category['category_id'];
$query = "SELECT * FROM bkg_forums WHERE category_id = :catid";
$query_params = array(':catid' => $catid);
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
} catch(PDOException $e) {
$error[] = "An error has occured. Please try again later.";
}
$forums = $stmt->fetchAll();
foreach($forums as $forum) {
print $forum['forum_id'];
}
}
?>
和html將其全部顯示在頁面上。
<?php foreach($categories as $category): ?>
<div><?php echo $category['category_name']; ?><?php echo $category['category_id']; ?></div>
<table width="100%">
<tr>
<td colspan="2">Forum</td>
<td>Lastest Post</td>
<td>Topics</td>
<td>Posts</td>
</tr>
<?php foreach($forums as $forum): ?>
<tr>
<td width="5%"></td>
<td><a href="viewforum.php?f=<?php echo $forum['forum_id']; ?>"><?php echo $forum['forum_name']; ?></a></td>
<td width="15%">
<!--<?php foreach($posts as $post): ?>
<a href="viewtopic.php?f=<?php echo $post['forum_id']; ?>&t=<?php echo $post['topic_id']; ?>#<?php echo $post['post_id']; ?>"><?php echo substr($post['post_subject'], 0, 10); ?></a>
<?php endforeach; ?>-->
</td>
<td width="5%" class="text-center"></td>
<td width="5%" class="text-center"></td>
</tr>
<?php endforeach; ?>
</table>
<?php endforeach; ?>
編輯：
我創建了四個類別
一般 發展 遊戲 題外話
，並用4 CATEGORY_ID 1論壇，以及1個論壇，顯示在每個類別。
