Example of code you should use. It's only example!
$data = array();
$query = $this->db->get( 'table' );
$result = $query->result();
$data[] = $result;
return $data;
Your code with little update
function get_actual_details_model($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;
}
you have to define you $data
first.
$data = array();
Change
$data[] = $result;
To
$data = $result;
在将任何数据放入$ data之前,将其定义为空数组,如下所示:
$data = array();
Your $data
variable is not defined. And it is appended with $result
Following is the updated code:
$data = array();
$query = $this->db->get();
$result = $query->result();
$data[] = $result;
