I am developing a movie ticket reservation system in codeigniter.The user can select his seat by checking the box on each available seat.When I try to store the checked valued in session data i get an error.Below is my code.
View select_seat

I'm getting this error
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: controllers/Movies.php
A quick finding:
You can't use as
$this->input->post('seats[]')
Instead
$seats = $this->input->post('seats');
Now seats having array of values.
You can change your code as below:
function select_combo(){
$data['seats']=$this->input->post("seats");
$this->session->set_userdata($data);
$this->load->model('combo_model');
$data['combos'] = $this->combo_model->get_combo();
$this->load->view('header');
$this->load->view('select_combo',$data);
}

I was searching online all day today and could not find any solution for adding a dynamic image to owl carousel from MySQL database with information. If anyone can help?
I have done something like the following but I am getting only one slide, Like bootstrap, it is not showing all the images and table information from the database. If I loop it gives me all the tables on the same page.
<link rel="stylesheet" type="text/css" href="http://www.24limousine.com/wp-content/themes/24Limousine/assets/css/owl.carousel.min.css">
<?php
$connect = mysqli_connect("localhost", "root", "", "testing");
function make_query($connect)
{
$query = "SELECT * FROM banner ORDER BY banner_id ASC";
$result = mysqli_query($connect, $query);
return $result;
}
function make_slide_indicators($connect)
{
$output = '';
$count = 0;
$result = make_query($connect);
while($row = mysqli_fetch_array($result))
{
if($count == 0)
{
$output .= '
<li data-target="#dynamic_slide_show" data-slide-to="'.$count.'" class="active"></li>
';
}
else
{
$output .= '

}
$count = $count + 1;

return $output;

in ajax is not getting call ie $.ajax is not working here and my controller ie welcome with method send_otp is not called here.
why my function in controller is not getting called
how to solve the issue
what is the proper way to call the controller function using base_url
i have check the console also it is not showing any error
I noticed that you are using site_url() slightly incorrectly: don't write index.php there, just use site_url('welcome/send_otp')
Don't forget you have an unconditional die() at the top of your send_otp method - it will prevent any code below itself from executing
I'm the newbie in Codeigniter. I put the textbox values to session and go to next page and when i click the back button on 2nd page, then the 1st page data should be still in textbox. How can I do that? Please help me.

Load library session in construct
class Welcome extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('session');
}
Open your autoload.php in applications/config/autoload.php
$autoload['libraries'] = array('session');
The session data is the least of your problems.
First off, $this->load->view('pg2'); does not call your other functions in your controller, it loads a view named 'pg2'. In your question you didn't show the names of your views but if 'View 1' is a file named pg1.php in the /views folder, your controller function could look like this:
public function pg1() {
$this->session->set_userdata('page1',$this->input->get());
$this->load->view('pg1');
}
And then you have to learn how to pass data to display in views too... Try to read up on the docs, for example here's the page on how views work: https://www.codeigniter.com/user_guide/general/views.html
