问题描述

萨拉姆,我遇到了一个在视图中未定义的变量的问题。我之前没有$data在控制器中使用变量。在我使用 之后$data,它仍然没有出现在我的视图中(称为仪表板)。有人可以帮我解决这个代码吗?

对不起,我知道以前有这样的问题。但我想知道我的,有什么问题,除了我在另一个文件中的代码很好

home.php 作为控制器

class Home extends CI_Controller{
public function __construct(){
    parent::__construct();
    $this->loginstatus->check_login();
    $this->load->library('template');
    $this->load->model('day_off_model');
}

public function index(){
    redirect('home/info');
}

public function info(){
    $data = array();
    $data['ym'] = date('Y-m');
    $this->template->display('information/dashboard');

    date_default_timezone_set('Asia/Tokyo');

    //$data['harian'] = 'a';
    // Get prev & next month
    if (isset($_GET['ym'])) {
        $ym = $_GET['ym'];
    } else {
        // Bulan ini
        $ym = date('Y-m');
    }
    //echo $ym;

    // Check format
    $timestamp = strtotime($ym . '-01');
    if ($timestamp === false) {
        $timestamp = time();
    }

    // Today
    $today = date('Y-m-j', time());

    // H3 title
    $html_title = date('m Y', $timestamp);

    $parts =  explode(' ',$html_title);
    $date   = $parts[0].' '.$parts[1];

    // return $date;
    // print_r($html_title);
    // die();

    $html_title=$this->tanggal->tanggal_indo_month_yeartext($date);

    // print_r($html_title);
    // die();

    // link prev next     mktime(hour,minute,second,month,day,year)
    $prev = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)-1, 1, date('Y', $timestamp)));
    $next = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)+1, 1, date('Y', $timestamp)));

    // Jumlah hari seblan
    $day_count = date('t', $timestamp);

    // 0:Minggu 1:Senin 2:Selasa ...
    $str = date('w', mktime(0, 0, 0, date('m', $timestamp), 1, date('Y', $timestamp)));
    //$str = date('w', mktime(0, 0, 0, date('m', $timestamp), 1, date('Y', $timestamp))); //senin, selasa, rabu

    // Create Calendar
    $weeks = array();
    $week = '';

    // cell dengan tabel kalender
    $week .= str_repeat('<td></td>', $str);
    //$week .= str_repeat('<td></td>', $str-1);

    for ( $day = 1; $day <= $day_count; $day++, $str++) {

        $date = $ym.'-'.$day;
        $exist = $this->day_off_model->get_all(false)->num_rows();
        // print_r($exist);
        // die();
        if ($today == $date) {
            $week .= '<td class="today">'.$day;
        } else {
            $week .= '<td>'.$day;
        }
        $week .= '</td>';

        // End of the week OR End of the month
        if ($str % 7 == 6 || $day == $day_count) {
        //if ($str % 7 == 0 || $day == $day_count) {
            if($day == $day_count) {
                // empty cell
                $week .= str_repeat('<td class="column_custom"></td>', 6 - ($str % 7));
                //$week .= str_repeat('<td></td>', 7 - ($str % 7));
            }

            $weeks[] = '<tr>'.$week.'</tr>';

            // weeks
            $week = '';
        }
    }
    //redirect('home/info');
}

dashboard.php 作为视图

<?php if($this->session->userdata('user_type_id')==TRUE){?>
<div class="row">
<div class="col-md-12">
    <h1>Sistem Informasi Absensi Kepegawaian</h1>
    <hr/>
    Informasi terbaru Absensi Kepegawaian<br/>
    Pascasarjana Universitas Diponegoro
    <?php echo validation_errors(); ?>
</div>
</div>
<div class="row">
<?php echo $ym; ?>
<div class="col-md-4">
    <h3><a href="?ym=<?php echo $prev; ?>">&lt;</a><?php echo $html_title; ?> <a href="?ym=<?php echo $next; ?>">&gt;</a></h3>
    <br>
    <table class="table table-bordered dashboard">
        <tr>
            <th class="th_custom" width="30px">Minggu</th>
            <th class="th_custom" width="30px">Senin</th>
            <th class="th_custom" width="30px">Selasa</th>
            <th class="th_custom" width="30px">Rabu</th>
            <th class="th_custom" width="30px">Kamis</th>
            <th class="th_custom" width="30px">Jum'at</th>
            <th class="th_custom" width="30px">Sabtu</th>
        </tr>
        <?php
            foreach ($weeks as $week) {
                echo $week;
            }   
        ?>
    </table>
</div>
</div>
<?php }
else{?>
<h3>Silahkan login sebagai admin terlebih dahulu</h3>
<?php }?>

我也很好奇$ym。变量$prev$html_title并且$next没有被识别。我应该通过此代码吗?

谢谢你

解决方案


我认为您正在寻找这种结构:

class Home extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        // load other stuff
    }

    public function index()
    {
        $this->info();
    }

    public function info()
    {
        $data = [];

        // group all data you wish to pass to the view inside the $data array in this format:
        // $data[<variableName>] = <variableValue>

        $this->load->view('myView', $data);
    }
}

您希望在视图中可用的所有变量都需要定义为您传递的数组中的键,在这种情况下$data

$data['myVar'] = 'myValue'

将对应于视图中的以下内容:

var_dump($myVar); // result: myValue

您可以对要传递的数组执行相同操作:

$data['myArray'] = [1, 2, 3, 4];

并在视图中访问它,如下所示:

var_dump($myArray); // result: [1, 2, 3, 4]
