Question

我试图从控制器内部的回调中获取一些额外的信息。

控制器要求验证：

$this->form_validation->set_rules('csvfile', 'Upload CSV', 'callback_csv_upload');

验证回调应该管理文件上传的所有内容。现在，我想要做的是将上传信息进一步用于控制器：

 $this->form_validation->set_rules('csvfile', 'Upload CSV', 'callback_csv_upload');

do something with --- $this->lists->csvinfo;

//控制器内的回调

function csv_upload(){
      if($_FILES['csvfile']['size'] != 0){
        $upload_dir = './uploads/';
        if (!is_dir($upload_dir)) {
             mkdir($upload_dir);
        }   
        $config['upload_path']   = $upload_dir;
        $config['allowed_types'] = 'csv|txt';
        $config['file_name']     = 'csv_'.substr(md5(rand()),0,7);

        $config['overwrite']     = false;
        $config['max_size']  = '5120';

        $this->load->library('upload', $config);
        if (!$this->upload->do_upload('csvfile')){
            $this->form_validation->set_message('csv_upload', $this->upload->display_errors());
            return false;
        }   
        else{
             $this->load->model('lists');
            $this->lists->set_csvinfo($this->upload->data());
            return true;
        }   
    }   
    else{
        $this->form_validation->set_message('csv_upload', "No csv file selected");
        return false;
    }
}

模型

Class Lists extends CI_Model
{
    public $csvinfo = 'xx';     

    function set_csvinfo($info){

        $this->csvinfo = $info;

    }

}

就像我在回调中做的那样，不会影响Model变量 - 在打印出默认的'xx'值时。如果我尝试在控制器中调用de set_csvinfo（），则变量正在改变，但从不在回调函数内调用。

Answer 1

我认为您的$csvinfo必须是一种数组，因为$this->upload->data()会返回数组

Class Lists extends CI_Model
{
    public $csvinfo = [];      

    function set_csvinfo($info){

        $this->csvinfo = $info;

    }

}

Answer 2

我的验证回调函数不会触发，除非调用$ this-＆gt; form_validation-＆gt; run（）;

function csv_upload(){
.......
$this->lists->csvinfo = 'upload info';
..........
}

$this->form_validation->set_rules('csvfile', 'Upload CSV', 'callback_csv_upload');

$this->form_validation->run();
do something with --- $this->lists->csvinfo;

从回调验证Code Igniter获取额外信息
