将值从一个函数传递到另一个函数时，视图文件未加载到 codeigniter 4 中？

Question

我需要帮助。在控制器中，当我从另一个函数调用一个函数时，视图文件未加载。只显示空白页。

在下面的代码中，我需要将数组 $calc 从 calc() 函数传递给 sem1() 函数。数组值在函数中传递，但 sem1() 函数中的视图文件未加载，仅显示空白页。我正在使用 CodeIgniter 4。请帮忙。

    public function calc()
    {
        $calc = [
            'regulation'    => $this->request->getPost("regulation"),
            'branch'        => $this->request->getPost("branch"),
            'calculation'   => $this->request->getPost("calculation"),
            "semester"      => $this->request->getPost("semester")
        ];

        if ($calc['calculation'] == "GPA") {
            if ($calc['semester'] == "Semester 1") {
                $this->sem1($calc);
            }
        }
    }

    public function sem1($calc = '')
    {
        $this->builder->select('elective, sub_code, sub_name');
        $this->builder->where('semester', $calc['semester']);
        $this->builder->where('branch', $calc['branch']);
        $query = $this->builder->get();
        $isElective = [0, 0, 0, 0, 0];

        return view('au/auform', ['query' => $query, 'semester' => $semester, 'isElective' => $isElective]);
    }

您应该添加回显以呈现视图：

public function calc(){
    $calc = [
        'regulation'    => $this->request->getPost("regulation"),
        'branch'        => $this->request->getPost("branch"),
        'calculation'   => $this->request->getPost("calculation"),
        "semester"      => $this->request->getPost("semester")
    ];

    if ($calc['calculation'] == "GPA") {
        if ($calc['semester'] == "Semester 1") {
            echo $this->sem1($calc);
        }
    }
}

While passing values from one function to another function the view files are not loading in codeigniter 4?
