I feel there is a small step that I am missing that apparently everyone on the other related questions understands.
I have created a simple CI 2 view, controller and model, shown below:
I have installed dompdf into the helpers folder like so:
Code:
applications/helpers/dompdf
applications/helpers/dompdf/dompdf_help.php
What I want to happen is when user clicks the submit button on the view page, send form data to the db, then get a pdf of that filled in form.
Between getting underdefined var errors or nothing at all, except for the data going to db, I can't see what I am missing.
Could some please guide me? What am I not getting here?
View:
In the interest of space I won't copy the view here, but it is just a basic CI form, first/last name, branch, open/close form, onsubmit for call quicksubmit controller
Controller:
Code:
<?php
class Quicksubmit extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->library('form_validation');
$this->load->database();
$this->load->helper('form');
$this->load->helper('url');
$this->load->model('quicksubmit_model');
}
function index()
{
$this->form_validation->set_rules('title', 'Title', 'required|trim|xss_clean|max_length[50]');
$this->form_validation->set_rules('first_name', 'First Name', 'trim|xss_clean|max_length[100]');
$this->form_validation->set_rules('last_name', 'Last Name', 'required|trim|xss_clean|max_length[100]');
$this->form_validation->set_rules('branch', 'Branch', 'trim|xss_clean|max_length[100]');
$this->form_validation->set_rules('zip', 'Zip', 'trim|xss_clean|is_numeric|max_length[7]');
$this->form_validation->set_error_delimiters('<br /><span class="error">', '</span>');
if ($this->form_validation->run() == FALSE) // validation hasn't been passed
{
$this->load->view('quicksubmit_view');
}
else // passed validation proceed to post success logic
{
$this->pdf($output);
$form_data = array(
'title' => set_value('title'),
'first_name' => set_value('first_name'),
'last_name' => set_value('last_name'),
'branch' => set_value('branch'),
'zip' => set_value('zip')
);
if ($this->quicksubmit_model->SaveForm($form_data) == TRUE) // the information has therefore been successfully saved in the db
{
redirect('quicksubmit/success'); // or whatever logic needs to occur
}
else
{
echo 'An error occurred saving your information. Please try again later';
}
}
}
function success()
{
redirect(base_url(),'refresh');
}
function pdf()
{
$this->load->helper(array('dompdf', 'file'));
$html = $this->load->view('quicksubmit_view', $data, true);
pdf_create($html, 'filename');
}
dompdf_help.php file
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
function pdf_create($html, $filename='', $stream=TRUE)
{
require_once("dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
if ($stream) {
$dompdf->stream($filename.".pdf");
} else {
return $dompdf->output();
}
}
?>
