insert and update in single form in CodeIgniter - php

Question

Here I have controller news.php:
<?php
class News extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url_helper');
}
public function index(){
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
public function view($slug = NULL)
{
$data['news_item'] = $this->news_model->get_news($slug);
if (empty($data['news_item']))
{
show_404();
}
$data['title'] = "News in Detail(s)";
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Create a news item 22';
$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('text', 'Text', 'required');
$data['updateid'] = '' ;
if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('news/create');
$this->load->view('templates/footer');
}
else
{
$this->news_model->set_news();
if($update == 1){
redirect('/news', 'location');
}
}
}
public function update($id){
$this->load->helper('form');
$this->load->library('form_validation');
$data['updateid'] = $id;
$data['title'] = "Update News in Detail(s)";
$data['update'] = $this->news_model->edit_load_data($id);
$this->load->view('news/create',$data);
if ($this->input->post('submit')) {
$update = $this->news_model->update_news($id);
if($update == 1){
redirect('/news', 'location');
}
}
}
}
?>
Here my model file news_model.php:
<?php
class News_model extends CI_Model{
public function __construct(){
$this->load->database();
}
public function get_news($slug= false){
if($slug == false){
$query= $this->db->get('news');
return $query->result_array();
}
$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
public function set_news(){
$this->load->helper('url');
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$data = array(
'title' => $this->input->post('title'),
'slug' => $slug,
//'text' => $this->input->post('text')
'text' => $this->input->post('select')
);
return $this->db->insert('news', $data);
}
public function edit_load_data($id){
$query = $this->db->get_where('news', array('id' => $id));
return $query->row_array();
}
public function update_news($id){
$this->load->helper('url');
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$data = array(
'title' => $this->input->post('title'),
'slug' => $slug,
//'text' => $this->input->post('text')
'text' => $this->input->post('select')
);
$this->db->where('id', $id);
return $this->db->update('news', $data);
}
}
?>
Here my form create.php file:
<?php echo validation_errors();
echo $updateid;
?>
<?php if($updateid == ''){ ?>
<?php echo form_open('news/create'); ?>
<?php } else { ?>
<?php echo form_open('news/update/'.$updateid); ?>
<?php } ?>
<label for="title">Title</label>
<input type="input" name="title" value="<?php echo $update['title']; ?>" /><br />
<label for="text">Text</label>
<textarea name="text" ><?php echo set_value('text'); ?></textarea><br />
<label for="text">Select</label>
<select name="select">
<option <?php if($update['text']=='text1'){ echo "selected";} ?> value="text1">text1</option>
<option <?php if( $update['text']=='text2'){ echo "selected";} ?> value="text2">text2</option>
</select>
<br />
<input type="submit" name="submit" value="Create news item" />
</form>
Here when I am going news/create in gives error:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: update
Filename: news/create.php
Line Number: 15
Backtrace:
File: C:\xampp\htdocs\mylab\application\views\news\create.php Line: 15
Function: _error_handler
File: C:\xampp\htdocs\mylab\application\controllers\News.php Line: 54
Function: view
File: C:\xampp\htdocs\mylab\index.php Line: 315 Function: require_once
" />
What can I do for that? I want add and edit for same file create.php
is it possible there?

Answer 1

I don't know that this will produce the outcome you want but it will prevent the use of undefined variables.
<?php
echo validation_errors();
$updateid = isset($updateid) ? $updateid : '';
echo $updateid;
if($updateid == '')
{
echo form_open('news/create');
}
else
{
echo form_open('news/update/'.$updateid);
}
if(!isset($update))
{
$update['title'] = NULL;
$update['slug'] = NULL;
$update['text'] = NULL;
}
?>
<label for="title">Title</label>
<input type="input" name="title" value="<?php echo $update['title']; ?>" /><br />
<label for="text">Text</label>
<textarea name="text" ><?php echo set_value('text'); ?></textarea><br />
<label for="text">Select</label>
<select name="select">
<option <?php
if($update['text'] == 'text1')
{
echo "selected";
}
?> value="text1">text1</option>
<option <?php
if($update['text'] == 'text2')
{
echo "selected";
}
?> value="text2">text2</option>
</select>
<br />
<input type="submit" name="submit" value="Create news item" />
</form>
You should probably modify your model so that it returns a default array if/when the inputs are not present. I am not able to identify where you are sending $update to the view either.

Answer 2

I think you're not returning $update['title'], $update['text'], etc.. You are returning $title, $text...
Try changing $update['title'] to $title in create.php to see what
happens
