我正在以这种方式进行数据库查询:
foreach ( $_SESSION['cart'] as $product )
{
$id = (int)$product['id'];
$select = $this->table->select();
$select->where("id=$id");
$this->view->products = $this->table->fetchAll($select);
}
在视图中,我是这样做的:
<?php foreach($this->products as $product) : ?>
<tr>
<td><img src="<?php echo $product->image;?>" width="190px"/><td>
<td><?php echo $product->name;?><td>
<td><?php echo $product->weight/1000 ?><td>
<td><?php //echo $this->currency($product->price);?><td>
<td>x<td>
<td><input type="text" value="<?php echo $_SESSION['cart'][$product->id]['qtd'] ?>" /><td>
<td><input type="submit" name="remove" value="Remover" /><?php echo $product->id; ?><td>
</tr>
<?php endforeach; ?>
但结果为空。任何人都可以帮助我吗?
- UPDATE -
我试着这样做:
$this->view->products = array();
foreach ( $_SESSION['cart'] as $product )
{
$id = (int)$product['id'];
$select = $this->table->select();
$select->where("id=$id");
$this->view->products[$id] = $this->table->fetchAll($select);
}
但结果仍为空。我设法做旧的方式,但我只返回最后的结果,因为数组被覆盖。

您缺少'from'部分,因此查询不知道要从哪个表中进行选择。
