在制作样本详细信息页面时,我只是陷入了一个非常令人困惑的情况.我真正想要做的是这样的:

+----------------------------------------------------+
+ Year  | Month   | Date        | Total Gain +
+----------------------------------------------------+
+ 2003  | January | 26/01/2003  |  +90 %             + 
+ 2003  | January | 27/01/2003  |  +10 %             +   
+ 2003  | Feburary| 01/02/2003  |  -29 %             +
+ 2003  | Feburary| 15/02/2003  |  +0.52 %           +
+----------------------------------------------------+

我真正想要的是,我可以列出月份名称和年份明智 mysql_query('SELECT month FROM mytable WHERE year="2003"');

但问题是它显示了1月份的两次.我想显示一月份的1月份和旁边的链接,它将进入下一页.这将显示1月份的统计数据.

如何从文本文件中删除除前20行之外的每一行？

我的Grid.php文件中有以下代码:

function _prepareCollection () {
$collection = Mage::getResourceModel($this->_getCollectionClass());
$collection->getSelect()->joinLeft(
    array('sfog' => 'sales_flat_order_grid'),
    'main_table.entity_id = sfog.entity_id',
    array('sfog.shipping_name','sfog.billing_name')
);
$collection->getSelect()->joinLeft(
    array('sfo'=>'sales_flat_order'),
    'sfo.entity_id=main_table.entity_id',
    array(
        'sfo.customer_email',
        'sfo.weight',
        'sfo.discount_description',
        'sfo.increment_id',
        'sfo.store_id',
        'sfo.created_at',
        'sfo.status',
        'sfo.base_grand_total',
        'sfo.grand_total'
    )
);

我想添加表sales_order_item,但如果我添加此表,我会收到此错误:

具有相同id"119"的Item(Mage_Sales_Model_Order)已经存在

无论如何围绕这个？

我有一个PHP数组如下:

$array = array("one" => "is one" , "two" => "is two" , "three" => "is three", "four" => "is four" , "five" => "is five" , "six" => "is six" , "seven" => "is seven" , "eight" => "is eight" , "nine" => "is nine" , "ten" => "is ten");

将此数组分为两组,即5个元素后,使用以下方法:

 function partition(Array $list, $p) {
    $listlen = count($list);
    $partlen = floor($listlen / $p);
    $partrem = $listlen % $p;
    $partition = array();
    $mark = 0;
    for($px = 0; $px …
