Hope this will help you :
Arguments mismatch with updaterecords method in controller with model
Should be like this :
Call updaterecords method in your controller like this :
$this->Contact_model->updaterecords($id, $data);
Your model method should be like this :
function updaterecords($id,$data,)
{
$this->db->where('id', $id);
$this->db->update('about_us1', $data);
}
UPDATE :
your controller code should be like this :
if($this->input->post('update'))
{
$data = array();
$id = $this->input->post('id');
$data['first_content']=$this->input->post('first_content');
$data['second_content']=$this->input->post('second_content');
$data['third_content']=$this->input->post('third_content');
$data['fourth_content']=$this->input->post('fourth_content');
$this->Contact_model->updaterecords($id, $data);
redirect("Home/About_us_display");
}

i want to print post data in my login function with $this->input->post['username'];
I have a home controller given below :
<?php
class Home extends CI_Controller{
public function index(){
$this->load->view("home/home_view");
}
public function Login(){
echo $this->input->post['username'];
}
}
?>
but its showing me null result but if i write print_r($_POST) instead of $this->input->post['username'] its showing me all data
this is my home view code

i had auto loaded form helper and url helper
Hope this will help you :
Use $this->input->post('username'); instead of $this->input->post['username'] :
Your Login function should be like this :
public function Login()
{
/* to print all field name do like this*/
print_r($this->input->post());
/* to print a particular field name do like this*/
echo $this->input->post('username');
echo $this->input->post('password');
}
Use site_url or base_url in form like this ( good practice) :
<form method="post" action="<?php echo site_url('Home/Login'); ?>">
........
</form>
for more : https://www.codeigniter.com/user_guide/libraries/input.html
Convert your HTML from into CI form helper way although i have updated your view file for your reference see form helper [https://www.codeigniter.com/userguide3/helpers/form_helper.html][1]

This is very quick.
I have a form that when submitted should add user input into my DB. I have had a similar form working well but for some reason this one is not working.
Please excuse my sloppy code but here is the whole page. For some reason 'observation' will not take the user input and display it on the next page (showOne.php). The next page simply shows a blank space for observation and I checked the DB and there was nothing in the observation field of course.
Is it something simple that I can't see? I've been at this for days since it is identical to another form I have that works well on another page.
Thank you for any insight.
<?php
//including the database connection file
include("config.php");
$activePage = "start.php";
if(isset($_POST['update'])) {
$id = $_POST['id'];
$observation = $_POST['observation'];
$result = mysqli_query($mysqli, "UPDATE tasks SET observation='$observation' WHERE id=$id");
header("Location: showOne.php?id=$id");
}
//getting id from url
$id = $_GET['id'];
//selecting data associated with this particular id
$result2 = mysqli_query($mysqli, "SELECT * FROM users WHERE id=$id ORDER BY id ASC");
$result = mysqli_query($mysqli, "SELECT * FROM tasks ORDER BY taskNumber ASC");
include_once "nav.php";
?>

SearchText works if record is found but errors appear when record not found.
Here are the errors. Notice: Undefined variable: sample_list in C:\xampp\htdocs\viewsample\samplelist.php on line 166
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\ viewsample\samplelist.php on line 166
If I click the search button again, errors disappear.
Is it possible to return to home page if record not found?
I searched here a possible solution to my problem but I found none.
Please help.
Thank you and more power.

If no records are found in DB the $sample_list array is empty.
So samplelist.php needs this check before foreach loop,
if (empty($sample_list))
{
header('Location: http://www.homesweet.home/');
exit;
}
foreach($sample_list as $collection) :
...
endforeach;

class Productlist_controller extends CI_Controller {
function __construct(){
parent::__construct();
}
public function index()
{
if(isset($_POST["btn_delete"])){
$pid = $_POST["btn_delete"];
$this->load->model('product_model');
$result = $this->product_model->deleteProduct($pid);
if($result==true){
$data = array();
$this->load->model('product_model');
$data['products'] = $this->product_model->availableProductList();
$this->load->view('admin_product_list_view',$data);
}
else{
echo "Oops! Error occured..!";
}
}
else if(isset($_POST["btn_edit"])){
$pid = $_POST["btn_edit"];
$data = array();
$this->load->model('product_model');
$data['product'] = $this->product_model->readProduct($pid);
//$this->load->model('category_model');
//$data['categories'] = $this->category_model->getCategories();
$this->load->view('admin_product_edit_view', $data);
}

Now the problem is in the controller i need to load up categories (which I have commented) in order to show them in the edit view, but when I un-commented it, categories are loading, but Gives an Error in Item Description textarea saying
Message: Undefined property: stdClass::$itemdesc
With the category model loading line commented, it works fine except no categories will load up in the dropdownlist,Please someone suggest me a way to get rid of this.
Please use this in your view
if(isset($row->itemdesc)) echo $row->itemdesc;
I think this will solve your problem
I saw that you got an answer but i have a few suggestions for your code:
1. in your controller you load the model 3 times: you should load it once; you could do something like this:
if(!empty($_POST)){
$this->load->model('product_model');
if(isset($_POST["btn_delete"])){
//some code
}elseif(isset($_POST["btn_edit"])){
//some other code
}
}
2. in your views you load a helper: this should be loaded into the controller, right after the first verification from point 1.
3. in views you should check your variable for content, especially the ones that you are going to use in a loop, like $products
