Joomla2.5 joomla 2.5中多个表中的数据值重复

我正在开发MVC组件，并从joomla 2.5中的两个表中获取数据，但我遇到了一个问题，航班信息有不同类型的票价，所以当它在表中显示输出时，它会显示重复的值。下面是示例代码

质疑

鉴于

<?php foreach($this->items as $i => $value):
?>
    <tr class="row<?php echo $i % 2; ?>">
        <td>
            <?php echo $value->flight_child_id; ?>
        </td>
        <td>
            <?php echo JHtml::_('grid.id', $i, $value->flight_child_id); ?>
        </td>
        <td><?php echo $value->flight_name; ?></td> 
            <td><?php echo $value->flight_code; ?></td>
            <td><?php echo $value->flight_dep_date; ?></td>
            <td><?php echo $value->flight_ari_date; ?></td>
            <td><?php echo $value->flight_dep_time; ?></td>
            <td><?php echo $value->flight_ari_time; ?></td>
            <td><?php echo $value->flight_dep_city; ?></td>
           <td><?php echo $value->flight_ari_city; ?></td>
           <td><?php    
         echo $value->fair_type; 
             echo $value->fair; ?>
            </td>
         </tr>
<?php endforeach; ?>

第4行打印了5次，因为有五种类型的票价

重复值原因：您的

#uu fairinfo

表有一行，而

#uu faredescription

表有4行，因此仅显示重复值

看来你的期望是这样的

是吗？

请这样做

$query->select('f.flight_child_id,f.flight_name,f.flight_code,f.flight_dep_date,f.flight_ari_date,f.flight_dep_time,f.flight_ari_time,f.flight_dep_city,f.flight_ari_city,f.flight_child_id');
        $query->from('#__fairinfo as f');                

鉴于

<?php foreach($this->items as $i => $value):
?>
    <tr class="row<?php echo $i % 2; ?>">
        <td>
            <?php echo $value->flight_child_id; ?>
        </td>
        <td>
            <?php echo JHtml::_('grid.id', $i, $value->flight_child_id); ?>
        </td>
        <td><?php echo $value->flight_name; ?></td> 
            <td><?php echo $value->flight_code; ?></td>
            <td><?php echo $value->flight_dep_date; ?></td>

            <td><?php echo $value->flight_dep_time; ?></td>
            <td><?php echo $value->flight_ari_time; ?></td>
            <td><?php echo $value->flight_dep_city; ?></td>
           <td><?php echo $value->flight_ari_city; ?></td>
           <td><?php 
                $model = $this->getmodel('Your model name');
                echo nl2br($model->functionname($value->flight_child_id));
            ?></td>
         </tr>
<?php endforeach; ?>

我认为，因为加入查询，它给出了这种类型的结果，我知道在关系代数中，它本身就被删除了，但在这种情况下，我们如何消除重复？我的名声不太好，它不允许我放弃投票，但我接受了你的答案

$query->select('f.flight_child_id,f.flight_name,f.flight_code,f.flight_dep_date,f.flight_ari_date,f.flight_dep_time,f.flight_ari_time,f.flight_dep_city,f.flight_ari_city,f.flight_child_id');
