Php Codeigniter无法调用控制器内的函数

谢谢你的回答

所以我的Codeigniter还有一个问题，它仍然是同一个项目，只是计算数据库中的数据行

我想做的是在控制器中创建一个函数，然后在视图中调用该函数

这是我的原始代码：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Dash_control extends CI_Controller {

    public function __construct()
       {
            parent::__construct();
            $this->load->database();
            $this->load->model('dash_model');
       }



    public function index()
    {
        $data['cashtotal']=$this->dash_model->totalCash();
        $data['approvedtocash']=$this->dash_model->cashapproved();
        $data['rejectedtocash']=$this->dash_model->cashrejected();

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

}

我做错了什么？有什么我遗漏的吗？ 所以我不能在控制器内创建多个函数？ 谢谢你

更新

我听从了萨蒂的指导，结果成功了。谢谢！ 由于这是一个表，我想添加另一个函数，因此我将其添加如下：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Dash_control extends CI_Controller {

    public function __construct()
       {
            parent::__construct();
            $this->load->database();
            $this->load->model('dash_model');
       }



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

    public function CashTransSum()
    {
        $data['cashtotal']=$this->dash_model->totalCash();
        $data['approvedcash']=$this->dash_model->cashapproved();
        $data['rejectedcash']=$this->dash_model->cashrejected();

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

    public function PayTransSum()
    {
        $data['paytotal']=$this->dash_model->totalPay();
        $data['approvedpay']=$this->dash_model->payapproved();
        $data['acqrejectedpay']=$this->dash_model->payrejected();

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

}

这里说我需要给它打一次电话。。。哪一个？我把密码搞错了吗

您需要在

索引

函数中调用另一个函数（）

 public function index()
    {

        $this->anotherfunction();// call your function
    }
public function anotherfunction()
    {
        $data['cashtotal']=$this->dash_model->totalCash();
        $data['approvedtocash']=$this->dash_model->cashapproved();
        $data['rejectedtocash']=$this->dash_model->cashrejected();

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

您需要在

索引中调用
另一个函数（）
，如下所示

 public function index()
    {

        $this->anotherfunction();// call your function
    }
public function anotherfunction()
    {
        $data['cashtotal']=$this->dash_model->totalCash();
        $data['approvedtocash']=$this->dash_model->cashapproved();
        $data['rejectedtocash']=$this->dash_model->cashrejected();

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

您遇到的错误是完全正常的，您需要用所有变量填充
$data
数组，请尝试以下操作：

protected $data;

public function index()
{
    $this->CashTransSum();
    $this->PayTransSum();

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

public function CashTransSum()
{
    $this->data['cashtotal']=$this->dash_model->totalCash();
    $this->data['approvedcash']=$this->dash_model->cashapproved();
    $this->data['rejectedcash']=$this->dash_model->cashrejected();
}

public function PayTransSum()
{
    $this->data['paytotal']=$this->dash_model->totalPay();
    $this->data['approvedpay']=$this->dash_model->payapproved();
    $this->data['acqrejectedpay']=$this->dash_model->payrejected();
}

你还在上指数吗？如果是，则错误是正确的。如果您仍然想使用index方法，只需在那里包含声明即可。您仍然使用index吗？如果是，则错误是正确的。如果您仍然想使用index方法，只需在其中包含声明即可。
