我是smarty的新手。我需要在我的.tpl文件之一中执行以下代码:
<? // SELECT sql query
$sql = "SELECT 'id' , 'title' FROM `forum_posts` WHERE bid = '1' ORDER BY 'date' DESC LIMIT 4";
// perform the query and store the result
$result = query($sql);
// if the $result contains at least one row
if ($result->num_rows > 0) {
// output data of each row from $result
while($row = $result->fetch_assoc()) {
echo '<tr>
<td><a href="http://www.site.com/forum.php?topic='. $row['id']. '">'. $row['title']. '</a> </td>
</tr> ';
}
}
else {
echo 'No news';
}
?>
我已经试了3个小时了，在网上冲浪，但没有成功。请帮助!
您使用的是引号而不是反勾作为列名，只需更改它们以避免错误
SELECT `id` , `title` FROM `forum_posts` WHERE `bid` = '1' ORDER BY `date` DESC LIMIT 4";
require('../lib/SmartySQL.class.php');
$smarty = new SmartySQL(array('pdo_dsn' => 'mysql:dbname=db_name;host=localhost')，'pdo_username' => 'username'，'pdo_password' => 'password'，'pdo_driver_options' => array());
$ smarty ->显示("index.tpl");
