大家好模型,我给在功能如下错误消息:数据

$query = $this->db->get(); 
      $result = $query->result(); 
      $data[] = $result; 

但作为一个PHP错误遇到

严重性我得到的错误:请注意

消息:未定义变量:数据

文件名:型号/ survey_model.php

行号:845

什么是这一点。有人可以帮我请

function get_actual_details_model($fin_year,$state){ 
     $this->db->select('*'); 
     $this->db->from('survey_respondent_info'); 
     $this->db->where('state', $state); 
     $queryYr = $this->db->get(); 
     $resYr = $queryYr->result(); 
     foreach ($resYr as $surveyId) { 
      $this->db->select('budgets.*, budget_funding.*, marketing_budget.*, personnel_budget.*, grants_budget.*'); 
      $this->db->from('budgets'); 
      $this->db->join('budget_funding', 'budget_funding.budget_id = budgets.budget_id', 'left'); 
      $this->db->join('marketing_budget', 'marketing_budget.budget_id = budgets.budget_id', 'left'); 
      $this->db->join('personnel_budget', 'personnel_budget.budget_id = budgets.budget_id', 'left'); 
      $this->db->join('grants_budget', 'grants_budget.budget_id = budgets.budget_id', 'left'); 
      $this->db->where('budgets.financial_year',$fin_year); 
      $this->db->where('budget_option_id', 1); 
      $this->db->where('survey_id', $surveyId->survey_id); 
      $data = array(); 
$query = $this->db->get(); 
$result = $query->result(); 
$data[] = $result; 
     } 
     return $data; 
     }

你在哪里设置$的数据? – Anigel

你应该使用的代码的例子。 这只是一个例子!

$data = array(); 
$query = $this->db->get('table'); 
$result = $query->result(); 
$data[] = $result; 

return $data; 

你很少更新代码

function get_actual_details_model($fin_year,$state){ 
    $data = array(); // Data need to be in start 
    $this->db->select('*'); 
    $this->db->from('survey_respondent_info'); 
    $this->db->where('state', $state); 
    $queryYr = $this->db->get(); 
    $resYr = $queryYr->result(); 
    foreach ($resYr as $surveyId) { 
     $this->db->select('budgets.*, budget_funding.*, marketing_budget.*, personnel_budget.*, grants_budget.*'); 
     $this->db->from('budgets'); 
     $this->db->join('budget_funding', 'budget_funding.budget_id = budgets.budget_id', 'left'); 
     $this->db->join('marketing_budget', 'marketing_budget.budget_id = budgets.budget_id', 'left'); 
     $this->db->join('personnel_budget', 'personnel_budget.budget_id = budgets.budget_id', 'left'); 
     $this->db->join('grants_budget', 'grants_budget.budget_id = budgets.budget_id', 'left'); 
     $this->db->where('budgets.financial_year',$fin_year); 
     $this->db->where('budget_option_id', 1); 
     $this->db->where('survey_id', $surveyId->survey_id); 
     $query = $this->db->get(); 
     $result = $query->result(); 
     $data[] = $result; 
    } 
    return $data; 
}

显示你的所有模型,因为,如果它是相同的错误,那么问题就不存在了。 – Arturs

之前,你把任何东西在$数据,把它定义为空数组是这样的:没有定义

$data = array();

$data变量。 而且它附有$result

以下是更新后的代码:

$data = array(); 
$query = $this->db->get(); 
$result = $query->result(); 
$data[] = $result; 
2

你必须定义你$data第一。

$data = array(); 

变化

$data[] = $result; 

$data = $result;
