Question

我是一个控制器类，如图所示

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

  class Results extends CI_Controller
   {
    public function index()
   {
    $this->load->model('my_model');       
    }
   function validate()
    {
    //set validation rules here

    //validate form input
    if ($this->form_validation->run() == FALSE) {
        // fails
        $this->load->view('get_results');
    } 
}    
    function ranking1(){
    $data['returned_records']= $this->my_model- >get_ranking();
    $html=$this->load->view('view_ranking', $data, true);       
    $pdfFilePath = "ranking.pdf";        
    $this->load->library('m_pdf');
    //generate the PDF from the given html
    $this->m_pdf->pdf->WriteHTML($html);
    //download it.
    $this->m_pdf->pdf->Output($pdfFilePath, "D");
}    
function top5(){
    $data['returned_records']= $this->school_model->get_top5();       
    $html=$this->load->view('view_top5', $data, true);
    //this the the PDF filename that user will get to download
    $pdfFilePath = "top5.pdf";
    //load mPDF library
    $this->load->library('m_pdf');
    //generate the PDF from the given html
    $this->m_pdf->pdf->WriteHTML($html);

    //download it.
    $this->m_pdf->pdf->Output($pdfFilePath, "D");
    }
  }

我想从我的观点中调用这些函数：

  <a href="<?php echo base_url(); ?>results/top5">Top 5</a><br>
        <a href="<?php echo base_url(); ?>results/ranking1">ranking</a><br>

当我在 index（）方法中调用控制器中的函数时，它们工作正常但是在上面显示的 a tag 中调用它们确实有效。

我解决了。这是一个愚蠢的错误。我需要从控制器的构造函数中调用 my_model 来使函数访问。

调用控制器类
