My codeigniter site stopped outputting data from my database - database

Question

Good day internet. I am working on a basic cms using codeigniter. I have it set up so it is showing data from my database.
Here is the code in my controller for the first 2 pages
class Site extends CI_Controller {
public function index(){
$this->home();
}
public function home(){
$this->load->model("model_get");
$data["results"] = $this->model_get->getData("home");
$this->load->view("site_header");
$this->load->view("site_nav");
$this->load->view("content_home", $data);
$this->load->view("site_footer");
}
public function about(){
$this->load->model("model_get");
$data["results"] = $this->model_get->getData("about");
$this->load->view("site_header");
$this->load->view("site_nav");
$this->load->view("content_about", $data);
$this->load->view("site_footer");
}
Here is the model to get the data from the database
class Model_get extends CI_Model{
function getData($page){
$query = $this->db->get_where("pageData", array("page" => $page));
return $query->result();
}
}
Here is the view to output the data in the database
<div id="content">
<?php
foreach($results as $row){
$title = $row->title;
$text1 = $row->text1;
$text2 = $row->text2;
}
echo heading($title, 1);
?>
<p><?php echo $text1; ?></p>
<p><?php echo $text2; ?></p>
It has been working just fine but I wanted to use a form to change the data in the database. Here is the code for the view of my form
<div id="content">
<?php
$this->load->helper("form");
echo validation_errors();
echo form_open("site/updatevalues");
echo form_label("Heading", "title");
$data = array(
"name" => "title",
"id" => "title",
"value" => set_value("title"),
"style" => "width:100%",
"rows" => "rows:3"
);
echo form_textarea($data);
echo form_label("Text 1", "text1");
$data = array(
"name" => "text1",
"id" => "text1",
"value" => set_value("text1"),
"style" => "width:100%",
"rows" => "rows:3"
);
echo form_textarea($data);
echo form_label("Text 2: ", "text2");
$data = array(
"name" => "text2",
"id" => "text2",
"value" => set_value("text2"),
"style" => "width:100%",
"rows" => "rows:3"
);
echo form_textarea($data);
echo form_submit("dataSubmit", "Submit");
echo form_close();
?>
Here is the code snippet in my controller that is using the form inputs from the above view
public function updatevalues(){
$this->load->library("form_validation");
$this->form_validation->set_rules("title", "Heading", "required|xss_clean");
$this->form_validation->set_rules("text1", "Text 1", "required|xss_clean");
$this->form_validation->set_rules("text2", "Text 2", "required|xss_clean");
if($this->form_validation->run() == FALSE){
$data ["success"] = "";
$this->load->view("site_header");
$this->load->view("site_nav");
$this->load->view("data_input", $data);
$this->load->view("site_footer");
} else {
echo $data["success"] = "The page has been updated";
$this->load->view("site_header");
$this->load->view("site_nav");
$this->load->view("data_input", $data);
$this->load->view("site_footer");
$this->load->model("model_update");
$newRow = array(
"id" => "3",
"title" => set_value("title"),
"page" => "Contact Page", **<---This was the problem**
"text1" => set_value("text1"),
"text2" => set_value("text2")
);
$this->model_update->update1($newRow);
}
}
Here is the model that is handling updating the data in the database, I am just using the first function here
class Model_update extends CI_Model{
function update1($data){
$this->db->update("pagedata", $data, "id = 3");
}
function update2($data){
$this->db->update_batch("pagedata", $data, "id");
}
}
So after days of trying to figure this out I finally got it to update certain fields in the database which would theoretically update the output in the view but now it is giving me this error message:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: title
Filename: views/content_about.php
Line Number: 10
It is giving the error for all the variables I am trying to echo. I don't get it, I haven't touched the code to display from the database and now that I am finally able to change the data through a form the variable is all of a sudden undefined. If anyone can help me with this I would appreciate it. Been working on this single task for 2 weeks now!
Edit: As I was writing this up I figured out the problem and have put an arrow to identify it. The page data must be "about" because that is how the foreach loop is grabbing the data. I could just not post this but maybe this code will help someone else. Take what you can and enjoy internet you have just witnessed someone correcting themselves, lol.

Answer 1

Change this line in your site controller function home:
From this:
$data["results"] = $this->model_get->getData("home");
Into this:
$data["results"] = $this->model_get->getData("home page");
I know this because you took this from the youtube tutorial of Steven.
