Question

我试图从一个视图运行两个模型函数。第一个查询似乎工作正常。第二个查询返回一个空数组。我注意到在将查询打印到屏幕上时，查询似乎是连接在一起而不是分开的，如下所示：

JDatabaseQueryMySQL对象（[db：protected] =＆gt; JDatabaseMySQL对象（[name] =＆gt; mysql [nameQuote：protected] =＆gt;`[nullDate：protected] =＆gt; 0000-00-00 00:00： 00 [dbMinimum：protected] =＆gt; 5.0.4 [_database：JDatabase：private] =＆gt; Curling_Schedule [connection：protected] =＆gt;资源ID＃19 [count：protected] =＆gt; 0 [cursor：protected] = ＆gt;资源ID＃72 [debug：protected] =＆gt; [limit：protected] =＆gt; 0 [log：protected] =＆gt; Array（）[offset：protected] =＆gt; 0 [sql：protected] =＆gt ; SELECT team_name，division FROM #_ autoschedTeams ORDER BY division [tablePrefix：protected] =＆gt; encex [utf：protected] =＆gt; 1 [errorNum：protected] =＆gt; 0 [errorMsg：protected ] =＆gt; [hasQuoted：protected] =＆gt; [quoted：protected] =＆gt; Array（））[type：protected] =＆gt; select [element：protected] =＆gt; [select：protected] =＆gt; JDatabaseQueryElement Object（[name：protected] =＆gt; SELECT [elements：protected] =＆gt; Array（[0] =＆gt; sheet，id）[glue：protected] =＆gt;，）[delete：protec ted] =＆gt; [update：protected] =＆gt; [insert：protected] =＆gt; [来自：protected] =＆gt; JDatabaseQueryElement Object（[name：protected] =＆gt; FROM [elements：protected] =＆gt; Array（[0] =＆gt; #__ autoschedPlayingSheets）[glue：protected] =＆gt;，）[join：protected] =＆gt; [set：protected] =＆gt; [where：protected] =＆gt; [group：protected] =＆gt; [有：受保护] =＆gt; [columns：protected] =＆gt; [values：protected] =＆gt; [order：protected] =＆gt; JDatabaseQueryElement Object（[name：protected] =＆gt; ORDER BY [elements：protected] =＆gt; Array（[0] =＆gt; sheet）[glue：protected] =＆gt;，）[union：protected] =＆gt; [autoIncrementField：protected] =＆gt; ）

型号：

    public function getTeams()
    {


            // Create a new query object.           
            $db = JFactory::getDBO();
            $query = $db->getQuery(true);
            // Select some fields
            $query->select('team_name, division');
            // From the hello table
            $query->from('#__autoschedTeams');
            $query->order('division');      
            $db->setQuery((string)$query);
            $teams = $db->loadResultArray();
            $div = $db->loadResultArray(1);
            $divs = array_unique($div);
            $result = [];
            foreach($divs as $key)
            {
                $result[$key] = [];
                foreach(array_keys($div, $key) as $index)
                {
                   array_push($result[$key], $teams[$index]);
                }
            }
            return $result;
 }
             public function getSheets()
    {

            // Create a new query object.           
            $db = JFactory::getDBO();
            print_r($query);
            $query = $db->getQuery(true);
            // Select some fields
            $query->select('sheet, id');
            // From the hello table
            $query->from('#__autoschedPlayingSheets');
            $query->order('sheet'); 
            //print_r($query);  
            $db->setQuery($query);
            $result = $db->loadResultArray();
            return $result;

    }

}

来自View的相关代码：

$teams_sched = $this->get('Teams');
$sheets_sched = $this->get('Sheets');

更改变量的名称并使用它进行检查。

如果您没有再次获得结果，请打印查询echo $query;并进行检查。

public function getSheets()
{      
    $db     = JFactory::getDBO();               
    $query  = $db->getQuery(true);                
    $query->select('sheet, id');
    $query->from('#__autoschedPlayingSheets');
    $query->order('sheet'); 
    $db->setQuery($query);
    $Sheets = $db->loadResultArray();

    print_r($Sheets);

    return $Sheets;

}
