Joomla 查询显然运行了不止一次

我在 Joomla 网站的管理员中有一个报告组件。用户可以从可用报告类型的下拉列表中进行选择,然后调用函数来运行查询并输出 CSV 文件。在大多数情况下,这是有效的。然而,对于一份报告,我通过 Joomla 函数得到的结果数量与直接在 mySQL 中运行查询得到的结果数量不同。我添加了一个 error_log 来查看发生了什么,看起来好像查询运行了两次。 (也许吧。)

这是调用该函数的代码:

function getFullRedeemActivity($start, $end){

    return getReportFullRedeemActivityByDate("v.UpdateDT", strtotime($start),strtotime($end));

}

传入 $start 和 $end;那里没有问题。问题出在 getReportFullRedeemActivityByDate 函数中。这是代码:

function getReportFullRedeemActivityByDate($start, $end, $limitStart=null, $limitRows=null){
    //open db
    $db =& JFactory::getDBO();
    $where = ($low && $high) ? " and v.UpdateDT between ".$db->quote($low)." and ".$db->quote($high) : "";
     $sort = "v.UpdateDT";
     $limit = (is_int($limitStart) && is_int($limitRows)) ? " limit ".$db->quote($limitstart).", ".$db->quote($limitRows) : "";

    //set query
    $query = "select    r.RedeemAmt,
            v.VoucherNbr, v.BalanceInit, v.UpdateDT, v.BalanceCurrent, 
    m.SkuAbbr, m.MerchantNm,
    a.name,  a.email, a.company, a.address1, a.address2, a.city, a.state, a.zip, a.phone

            from arrc_RedeemActivity r
            left outer join arrc_Voucher v on v.VoucherID = r.VoucherID
            left outer join arrc_Merchant m on m.MerchantID = r.MerchantID
            left outer join jos_customers_addresses a on a.id = r.AcctID
           {$where} 
            order by {$sort} {$limit}";

    $db->setQuery($query);
    if (!$db->query()) error_log($db->stderr());

    if (!$db->getNumRows()){
        JError::raiseWarning( 100, 'No records returned' );
        return false;
    }
    else{
        error_log("there are ". $db->getNumRows()." rows");
    }

    //loop out records into array
    foreach ($db->loadAssocList() as $row){
        $data[$row['BalanceCurrent']] = $row;
        return $data;
    }
}

当我查看 error_log 时,我看到的是:

[Tue Oct 19 09:37:30 2010] [error] [client xxx.xx.xx.xxx] there are 5 rows, referer: http://mysite.com/administrator/index.php?option=com_arrcard&section=reports
[Tue Oct 19 09:37:30 2010] [error] [client xxx.xx.xx.xxx] there are 2 rows, referer: http://mysite.com/administrator/index.php?option=com_arrcard&section=reports

就像那样;一个接一个。鉴于打印出来的行不在循环内,我无法弄清楚为什么它显然运行该部分两次。

有什么想法吗?

I have a reporting component in the administrator of a Joomla site. The user can choose from a dropdown list of available report types, which then calls a function to run the query and output a CSV file. For the most part this works. However, for one report, I'm getting a different number of results through the Joomla function than I do if I run the query directly in mySQL. I added an error_log to see what was happening, and it appears as if the query is running twice. (Maybe.)

Here's the code that calls the function:

function getFullRedeemActivity($start, $end){

    return getReportFullRedeemActivityByDate("v.UpdateDT", strtotime($start),strtotime($end));

}

$start and $end are passed in; no problems there. The issue is in the getReportFullRedeemActivityByDate function. Here's the code for that:

function getReportFullRedeemActivityByDate($start, $end, $limitStart=null, $limitRows=null){
    //open db
    $db =& JFactory::getDBO();
    $where = ($low && $high) ? " and v.UpdateDT between ".$db->quote($low)." and ".$db->quote($high) : "";
     $sort = "v.UpdateDT";
     $limit = (is_int($limitStart) && is_int($limitRows)) ? " limit ".$db->quote($limitstart).", ".$db->quote($limitRows) : "";

    //set query
    $query = "select    r.RedeemAmt,
            v.VoucherNbr, v.BalanceInit, v.UpdateDT, v.BalanceCurrent, 
    m.SkuAbbr, m.MerchantNm,
    a.name,  a.email, a.company, a.address1, a.address2, a.city, a.state, a.zip, a.phone

            from arrc_RedeemActivity r
            left outer join arrc_Voucher v on v.VoucherID = r.VoucherID
            left outer join arrc_Merchant m on m.MerchantID = r.MerchantID
            left outer join jos_customers_addresses a on a.id = r.AcctID
           {$where} 
            order by {$sort} {$limit}";

    $db->setQuery($query);
    if (!$db->query()) error_log($db->stderr());

    if (!$db->getNumRows()){
        JError::raiseWarning( 100, 'No records returned' );
        return false;
    }
    else{
        error_log("there are ". $db->getNumRows()." rows");
    }

    //loop out records into array
    foreach ($db->loadAssocList() as $row){
        $data[$row['BalanceCurrent']] = $row;
        return $data;
    }
}

When I look at my error_log, what I see is:

[Tue Oct 19 09:37:30 2010] [error] [client xxx.xx.xx.xxx] there are 5 rows, referer: http://mysite.com/administrator/index.php?option=com_arrcard§ion=reports
[Tue Oct 19 09:37:30 2010] [error] [client xxx.xx.xx.xxx] there are 2 rows, referer: http://mysite.com/administrator/index.php?option=com_arrcard§ion=reports

Just like that; one after the other. Given that the line that prints that out is not inside a loop, I can't figure out why it's apparently running through that section twice.

Any ideas?

事实证明,并非所有返回的记录在 BalanceCurrent 列中都有值,因此当 foreach 命中此行时:

 $data[$row['BalanceCurrent']] = $row;

它不会为这些记录创建行。我将字段名称切换为所有行肯定都有的 id 列之一,一切都很好。

It turns out that not all records being returned had a value in the BalanceCurrent column, so when the foreach hit this line:

 $data[$row['BalanceCurrent']] = $row;

it wasn't creating a row for those records. I switched the field name to one of the id columns that all rows definitely have, and everything's fine.
