Unable to pass data from controller to view in codeigniter - php

Question

I'm having issues passing data from my controller to my view. I have a contenteditable div that I am saving the contents of to my database; I want to then display that in the view.
My controller
{
function __construct(){
parent::__construct();
$this->load->database();
$this->load->model('view_data');
$data = array();
}
public function index(){
$data['contactMe'] = $this->input->post('data');
$this->db->update('content', $data);
$results = $this->view_data->loadData();
$data['contactMeData'] = $results;
$this->load->view('pages/home', $data);
}
}
My model
<?php
class View_data extends CI_Model{
function __construct(){
parent::__construct();
}
public function loadData(){
$this->db->where('contactMe');
$query = $this->db->get('content');
return $query->result_array();
}
}
My view
<div class="w-100" ondblclick="makeEditable(this)" onblur="makeReadOnly(this)" contenteditable="true" id="contactMe">
<?php
foreach($contactMeData as $contact){
echo $contact;
}
?>
</div>
<button id="editBtn" type="submit" value="">Save changes
</button>
Every time I reload the page it replaces the data already in the database and I just get a blank div. I'm unable to view the data that was in the database to begin with.

Answer 1

try to add parameter on where
$this->db->where('contactMe',$parameter);
try to add field name on your view
echo $contact['field_name'];

Answer 2

This might be because every time you open the URL it updates the table, so you need a condition to check if POST request was made or not and then update the column
public function index(){
if($this->input->post()){ // check for post request
$data['contactMe'] = $this->input->post('data');
$this->db->update('content', $data); // try writing db queries in model
}
$results = $this->view_data->loadData();
$data['contactMeData'] = $results;
$this->load->view('pages/home', $data);
}
See, if it helps you.
