【问题描述】：

我有这个代码

 public function delete($delete_candindate)
    $this->load->database();
    $this->load->dbforge();
    $delete_candindate = $this->uri->segment(3);
    $this->dbforge->drop_table($delete_candindate);
    $this->db->where('dataset_name', $delete_candindate);
    $this->db->delete('all_datasets'); 
    $data['success_or_failure'] = 'That dataset already exists.Kindly go back and try again.';
    $this->load->view('success_or_failure');
    

我用来从我的表中删除一些数据，但我现在需要将数据从控制器传递到视图，但我的控制器有一个参数。

不知何故，变量$data['success_or_failure'] 没有被传递，因为我不断收到此错误

遇到了 php 错误

严重性：通知

消息：未定义变量：success_or_failure

文件名：views/success_or_failure.php

行号：54

为什么不将$data['success_or_failure'] = 'That dataset already exists.Kindly go back and try again.'; 传递给视图？

【参考方案1】：

发现我没有传递$data 变量

public function delete($delete_candindate) $this->load->database(); $this->load->dbforge(); $delete_candindate = $this->uri->segment(3); $this->dbforge->drop_table($delete_candindate); $this->db->where('dataset_name', $delete_candindate); $this->db->delete('all_datasets'); $data['success_or_failure'] = 'That dataset already exists.Kindly go back and try again.'; $this->load->view('success_or_failure',$data);
