Joomla：两个 mysql 查询模型功能与一个视图

Question

我正在尝试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，当将查询打印到屏幕上时，查询似乎连接在一起而不是分开的，如下所示：

JDatabaseQueryMySQL 对象 ( [db:protected] => JDatabaseMySQL 对象 ( [name] => mysql [nameQuote:protected] => ` [nullDate:protected] => 0000-00-00 00:00:00 [dbMinimum:protected] => 5.0.4 [_database:JDatabase:private] => Curling_Schedule [connection:protected] => 资源 id #19 [count:protected] => 0 [cursor:protected] => 资源 id #72 [debug:protected] => [limit:protected] => 0 [log:protected] => Array ( ) [offset:protected] => 0 [sql:protected] => SELECT team_name, Division FROM #_autoschedTeams ORDER BY Division [tablePrefix: protected] => encex [utf:protected] => 1 [errorNum:protected] => 0 [errorMsg:protected] => [hasQuoted:protected] => [quoted:protected] => 数组 ( ) ) [类型： protected] => 选择 [element:protected] => [select:protected] => JDatabaseQueryElement 对象 ( [name:protected] => SELECT [elements:protected] => 数组 ( [0] => Sheet, id ) [glue :protected] => , ) [delete:protected] => [update:protected] => [插入:protected] => [from:protected] => JDatabaseQueryElement 对象 ( [name:protected] => FROM [elements:protected ] => 数组 ( [0] => #__autoschedPlayingSheets ) [glue:protected] => , ) [join:protected] => [set:protected] => [where:protected] => [group:protected] => [having:protected] => [columns:protected] => [values:protected] => [order:protected] => JDatabaseQueryElement 对象 ( [name:protected] => ORDER BY [elements:protected] => Array ( [ 0] => 工作表 ) [胶水:受保护] => , ) [联合:受保护] => [自动增量字段:受保护] => )

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;

    }

}

查看相关代码：

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

Answer 1

更改变量的名称并检查它。

如果您没有再次得到结果，请打印查询

echo $query;

并检查它。

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;

}
