希望有人能找到我的问题的解决方案。我正在尝试使用谷歌地图和 PHP 创建仪表板。在尝试将其放入 MVC 模式之前，我能够显示图表，现在我得到的只是错误。（代码分为各自的文件夹模型、视图和控制器，根目录中有一个索引文件）。这是我到目前为止的代码
指数
<?php
include_once ("Design/includes.php");
$controller = new Controller();
$controller->invoke();
?>
控制器
<?php
class Controller {
public $model;
public function __construct()
{
$this->model = new tableModel();
}
public function invoke()
{
$this->model -> tableData();
include 'view/homeScreen.php';
}
}
?>
模型（这是表格，另一个模型在同一个文件夹中但完全相同）
<?php
class tableModel {
public function tableData(){
global $con;
$result = mysqli_query ( $con, "SELECT fk_EXECUTION_LAB_MACHINE as LAB_MACHINE, COUNT(fk_EXECUTION_LAB_MACHINE) as TOTAL
FROM EXECUTION_QUEUE
WHERE fk_EXECUTION_LAB_MACHINE IS NOT NULL and WEEK (TEST_START_TIME) = WEEK( current_date ) -1 AND YEAR( TEST_START_TIME) = YEAR( current_date )
GROUP BY fk_EXECUTION_LAB_MACHINE order by count(fk_EXECUTION_LAB_MACHINE) desc;");
$rows = array();
$table = array();
$table['cols'] = array(
// Labels for chart/column titles
array('label' => 'LAB_MACHINE', 'type' => 'string'),
array('label' => 'TOTAL', 'type' => 'number')
);
//Getting results array and populating table
$rows = array();
while($r = mysqli_fetch_array($result)) {
$temp = array();
$temp[] = array('v' => (string) $r['LAB_MACHINE']);
$temp[] = array('v' => (int) $r['TOTAL']);
$rows[] = array('c' => $temp);
}
//Get table in JSON format
$table['rows'] = $rows;
$jsonTable = json_encode($table);
echo $jsonTable;
return $jsonTable;
mysqli_close ( $con );
}
}
?>
这是视图

正如我之前所说，当我将视图和表数据放在一个文件夹中时，这些图表运行良好，但现在我将其放入 MVC 样式中，它不再起作用。这是我得到的错误
{"cols":[{"label":"LAB_MACHINE","type":"string"},{"label":"TOTAL","type":"number"}],"rows":[{"c":[{"v":"LIT-QAVIST-20"},{"v":1}]},{"c":[{"v":"LIT-QAVIST-25"},{"v":1}]}]}Warning: mysqli_query(): Couldn't fetch mysqli in C:\Users\n0237569\workspace\Dashboard MVC\Design\model\tableModel.php on line 11

Warning: include(): Failed opening 'view/homeScreen.php' for inclusion (include_path='.;C:\php\pear') in C:\Users\n0237569\workspace\Dashboard MVC\Design\controller\Controller.php on line 17
正如您从第一个错误中看到的那样，它以 json 格式返回数据，但我不确定接下来会发生什么。
这是包含文件夹的内容，因为最后两个错误引用了它
包括
<?php
require_once "Design/config.php";
require_once "Design/connection.php";
require_once "Design/model/pieModel.php";
require_once "Design/model/tableModel.php";
require_once "Design/controller/Controller.php";
?>
任何帮助将不胜感激
谢谢
