Question

我从数据库表Games_Model()中的模型match_schedule获取匹配项，模型100％正常工作没问题。然后，我将模型方法getMatchInfo()传递给视图，并将其分配给$data变量$data['games']，该变量作为view方法中的参数传递

    $data['games'] = $this->games_model->getUpcomingGames();
    $this->load->view('templates/upcoming_fixtures_tbl', $data);

输出

当我在print_r($games)中templates/upcomg_fixtures.php时，我得到以下内容：

Array (
    [0] => stdClass Object
        (
            [gameID] => 380
            [weekNum] => 1
            [gameTimeEastern] => 2018-06-14 18:00:00
            [homeID] => Russia
            [homeScore] => 
            [visitorID] => Saudi Arabia
            [visitorScore] => 
            [overtime] => 
            [tournament] => Fifa World Cup
            [sport] => soccer
            [location] => Luzhniki Stadium, Moscow
        )

    [1] => stdClass Object
        (
            [gameID] => 123
            [weekNum] => 1
            [gameTimeEastern] => 2018-09-06 20:20:00
            [homeID] => Philadelph
            [homeScore] => 
            [visitorID] => Atlanta Falcons
            [visitorScore] => 
            [overtime] => 
            [tournament] => NFL
            [sport] => AM Football
            [location] => Lincoln Financial Field
        )

    [2] => stdClass Object
        (
            [gameID] => 81
            [weekNum] => 14
            [gameTimeEastern] => 2018-05-18 00:00:00
            [homeID] => Hurricanes
            [homeScore] => 0
            [visitorID] => Reds
            [visitorScore] => 0
            [overtime] => 
            [tournament] => Super Rugby
            [sport] => rugby
            [location] => Westpac Stadium
        )

)

问题

但是，一旦我尝试使用$games变量，我就会收到错误

foreach ($games as $game){ echo $game['gameID']; }

致命错误：无法使用stdClass类型的对象作为数组

问题

如何访问游戏变量？

相关代码如下：

class Users extends CI_Controller {
public function dashboard($page = 'dashboard')
    {
        if(!file_exists(APPPATH . '/views/users/' . $page . '.php')){
            show_404();
        }
        //HERE DATA GETS PASSED AS ARRAY
        $data['games'] = $this->games_model->getUpcomingGames(); 

        $data['title'] ='WELCOME USER';
        $this->load->view('templates/header', $data);
        $this->load->view('users/' . $page, $data);
        $this->load->view('templates/upcoming_fixtures_tbl', $data);
        $this->load->view('templates/footer', $data);

模板/ upcomg_fixtures.php

foreach ($games as $game)
{
    echo $game['gameID'];
}

结果

致命错误：无法使用stdClass类型的对象作为数组

视图

如何在我的视图中访问数组索引？

希望这会对您有所帮助

func retrieveMonthlySpent(month:String, year:String) -> Double { FirebaseFunctions().retrieve(from: .expense, username: self.username as! String, returning: Expenses.self) { (expenses) in self.monthlyExpenses = expenses } var sum:Double = 0 for expense in self.monthlyExpenses{ if expense.modificationDate.convertToMonth() == month && expense.expense && expense.modificationDate.convertToYear() == year { sum += expense.convertedAmount } } return sum }是一个对象数组

在您的视图func retrieveMonthlySpent(month:String, year:String) -> Double{ FirebaseFunctions().retrieve(from: .expense, username: self.username as! String, returning: Expenses.self) { (expenses) in self.monthlyExpenses = expenses var sum:Double = 0 for expense in self.monthlyExpenses{ if expense.modificationDate.convertToMonth() == month && expense.expense && expense.modificationDate.convertToYear() == year{ sum += expense.convertedAmount } } } return sum }中执行此操作：

$games

CodeIgniter将数组信息传递给$ data变量
