Access return value from result() function - php

Question

Trying to get the result of my query send it back to controller and return it to a view and access it there. I can't seem to display the value at my view so I tried echoing out what I got as a result from controller. It keeps stating undefined offset 1...please tell me how to access model return value properly
Model
$output = $this->db->query("SELECT * from incoming ORDER BY incomingId LIMIT 20");
return $output->result();
Controller
$data = $this->search_form->searchIdIncoming($searchQuery);
echo $data[0][1];
$this->load->view("searchIncoming", $data);
View
if(isset($incomingId))
echo "Primary key is available";

Answer 1

Try
echo $data[0]["Your Database field name"]; instead of echo $data[0][1];
like
echo $data[0]["id"];

Answer 2

If you want to display the result from model in view the most appropriate way is like this:
1) Return the resultant records from the model as an array like:
$output = $this->db->query("SELECT * from incoming ORDER BY incomingId LIMIT 20");
return $output->result();
2) Access this value in Controller by calling the function for this model query say (as you have not detailed well, I am not sure which function you are using),
$data['details'] = $this->search_form->searchIdIncoming($searchQuery); // store the result in an array
and pass the array to the view
$this->load->view("searchIncoming", $data);
3) In the view file, you can display the records with
if(!empty($details))
{
foreach($details as $row)
{
if($row->incomingId!=0)
echo "Primary key is available";
...........
}
}

I finally made it work by replacing the result() function with the result_array() function in codeigniter added a few other stuff to properly get table functions but here's the result I got:
$rows[] = array();
$rows2[] = array();
$rows3[] = array();
$i = 0;
$companyName = $this->db->query("SELECT id, name from company");
foreach($companyName->result_array() as $row2){
$rows2[$i]['id'] = $row2['id'];
$rows2[$i]['name'] = $row2['name'];
$i++;
}
//get all company names
$i = 0;
$staffName = $this->db->query("SELECT id, surname, firstName, middleInitial from employee");
foreach($staffName->result_array() as $row3){
$rows3[$i]['id'] = $row3['id'];
$rows3[$i]['name'] = $row3['surname'].", ".$row3['firstName']." ".$row3['middleInitial'];
$i++;
}
//get all employee names
$i= 0;
$output = $this->db->query("SELECT * from incoming ORDER BY incomingId LIMIT 20");
if ($output->num_rows() > 0) {
foreach($output->result_array() as $row){
$count = 0;
$j = 0;
$rows[$i]['incomingId'] = $row['incomingId'];
$rows[$i]['referenceNo'] = $row['referenceNo'];
$rows[$i]['documentTypeId'] = $row['documentTypeId'];
$rows[$i]['documentDate'] = $row['documentDate'];
$rows[$i]['dateReceived'] = $row['dateReceived'];
$rows[$i]['sender'] = $row['sender'];
while($count < sizeof($rows2)){
if($rows2[$j]['id'] != $row['companyId']){
$j++;
}else{
$rows[$i]['companyName'] = $rows2[$j]['name'];
break;
}
$count++;
}
$j= 0;
$count = 0;
while($count < sizeof($rows3)){
if($rows3[$j]['id'] != $row['responsibleStaffId']){
$j++;
}else{
$rows[$i]['responsibleStaffName'] = $rows3[$j]['name'];
break;
}
$count++;
}
$rows[$i]['subject'] = $row['subject'];
$rows[$i]['actionDone'] = $row['actionDone'];
$rows[$i]['track'] = $row['track'];
$rows[$i]['completed'] = $row['completed'];
$rows[$i]['remarks'] = $row['remarks'];
$i++;
}
return $rows;
}
return false;
