I'm trying to do URL format likes below
for pages -
www.example.com/page-name
for categories
www.example.com/category-name/sub-category-name
for product
www.example.com/category-name/sub-category-name/product-name
This should not be a problem if you are using only one controller i.e. your default controller. Say your default controller is called "Home". Then you can simply do this.
class Home extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('Home_model');
}
public function _remap()
{
$category = $this->uri->segment(2);
$sub_category = $this->uri->segment(3);
$product = $this->uri->segment(4);
// Check what you have
// echo $category.'_'. $sub_category.'_'. $product;
if($category == '' || $sub_category == '' || $product == '')
{
//send user to landing page of website
$this->load->view('landing');
}
else
{
// get the product details
$render['product_details] = $this->Home_model->get_product_details($category, $sub_category, $product);
// send product details to view
$this->load->view('product_details', $render);
}
}
}

I'm trying to understand Joomla language and I have this situation:
In a models/calcoloonline.php I have this function
public function estraivariabili()
{
$db = JFactory::getDBO();
// Put the result into a variable first, then return it.
$value = $db->setQuery("SELECT * FROM #__calcolo_imposte")->loadObjectList();
if ($value != NULL)
{
return $value;
}
else
{
return JFactory::getApplication()->enqueueMessage(JText::_('COM_CALCOLO_IMPOSTE_IMPORTI_NON_DEFINITI'), 'type');
}
}
This works perfectly but I'd like that after check if the return is NULL I want to hide display default.php and show only the message on JText.
How can I do this?
For your purpose, you just return the $value from the model function and call the function at view.html.php's display() function.
At default.php file check the availability of the $value and show your contents.
For example, you store the data at view.php.html. It looks like
public function display($tpl = null)
{
$model = $this->getModel();
$this->value = $model->estraivariabili();
return parent::display($tpl);
}
And your default.php file would be
<?php if (!empty($this->value)) { ?>
<h1>The value is not empty.</h1>
<?php } else {
// value not found :(
JFactory::getApplication()->enqueueMessage(JText::_('NOT_FOUND_MESSAGE'), 'warning');
} ?>
I am new in codeigniter.
Currently working in e-commerce site I want to send the category_id as parameter to bring product data.
I want to know the steps to detail and Thanks
This is my model:
( function get_category(){ $query = $this->db->query("SELECT a.category_id,a.category_name from ci_intro.categories a order by a.category_id"); return $query->result(); } function get_product($id){ $q = $this->db->query('select * from products where category_id = $id'); if($q->num_rows() > 0){ foreach ($q->result() as $row) { $data[] = $row; } return $data; } } )
and this is my controller
( public function services() { $this->load->model("get_db"); $data['results'] = $this->get_db->get_category(); $id=$this->input->post('id'); $data['cat_id'] = $this->get_db->get_product($id); $this->load->view("view_header"); $this->load->view("view_nav"); $this->load->view("content_portfolio",$data); $this->load->view("site_footer"); } )
You get category_id in model as $_GET['category_id'] or $_REQUEST['category_id'] in model also .
class Pages extends CI_Controller {
public function view($page = 'home')
{
$this->load->model('services_model');
$id=$this->input->post('id');
$data['records']= $this->services_model->getData($id);
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
}
this is your controller example
and this is mlodel for you
class Services_model extends CI_Model {
function getUser($id) {
$q = $this->db->query('YOUR QUERY HERE');
if($q->num_rows() > 0){
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
}
you can see various crud example and their website for further details
Your category should be the drop downlist. on change event the id will be pass through ajax like below
$(document).ready(function() {
$("#category").change(function(){
/*dropdown post */
$.ajax({
url:"<?php echo base_url(); ?>index.php/services/getproducts",
data: {catid: $(this).val()},
type: "POST",
success: function(data){
$("#product").html(data);
}
});
});
}
get prducts will be the function in services controller class you can get the category id using the
$this->input->post('catid');
i am currently working on a project where users can save note snippets in there own little user area.
I was wondering how would i check if the id of an item exists for example if a user visits
http://mysite.com/view/1 and there is a note snippet of 1 it will display all the data relating to the id of one. Now if the user was to change the url to lets say 1000, that id doesnt exist and the view just errors.
i want to be able to redirect them back to a certain page with a error message "snippet does not exist" etc.
heres what i have so far ( i currently already have a conditional statement in here to check if the snippet is private, then if it is redirect back to /publicsnippets)
Controller:
class Publicsnippets extends CI_Controller {
function __construct()
{
parent::__construct();
if (!$this->tank_auth->is_logged_in()) {
redirect('/login/');
}
$this->load->model('dashboard_model');
$this->data['user_id'] = $this->tank_auth->get_user_id();
$this->data['username']= $this->tank_auth->get_username();
}
public function index()
{
$this->data['public_snippets'] = $this->dashboard_model->public_snippets();
$this->load->view('dashboard/public_snippets', $this->data);
}
public function view($snippet_id)
{
$snippet = $this->dashboard_model->get_snippet($snippet_id);
if ($snippet['state'] === 'private')
{
$this->session->set_flashdata('message', "<b style=\"color:red;\">You are not allowed to view this snippet!</b>");
redirect('/publicsnippets');
} else {
$this->data['snippet'] = $snippet;
}
$this->load->view('dashboard/view_public_snippet', $this->data);
}
}
Model:
class Dashboard_model extends CI_Model {
public function public_snippets()
{
$this->db->select('id, title, description, tags, author, date_submitted');
$query = $this->db->get_where('snippets', array('state' => 'public'));
return $query->result_array();
}
public function private_snippets()
{
$this->db->select('id, title, description, tags, author, date_submitted');
$query = $this->db->get_where('snippets', array('user_id' => $this->tank_auth->get_user_id()));
return $query->result_array();
}
public function add_snippet($data)
{
$this->db->insert('snippets', $data);
$id = $this->db->insert_id();
return (isset($id)) ? $id : FALSE;
}
public function get_snippet($snippet_id) {
$query = $this->db->get_where('snippets', array('id' => $snippet_id));
return $query->row_array();
}
public function update_snippet($snippet_id, $data)
{
$this->db->where('id', $snippet_id);
$this->db->update('snippets', $data);
}
public function delete_snippet($snippet_id)
{
$this->db->where('id', $snippet_id);
$this->db->delete('snippets');
}
}
View:
<h3>Description</h3>
<p><?php echo $snippet['description']; ?></p>
<h3>Tags</h3>
<p><?php echo $snippet['tags']; ?></p>
<h3>Date Submitted</h3>
<p><?php echo $snippet['date_submitted']; ?></p>
<h3>Snippet</h3></pre>
<pre class="prettyprint"><?php echo $snippet['code_snippet']; ?></pre>
You work is fine just add a check like this in your view method
Controller
public function view($snippet_id)
{
$snippet = $this->dashboard_model->get_snippet($snippet_id);
if($snippet){
if ($snippet['state'] === 'private')
{
$this->session->set_flashdata('message', "<b style=\"color:red;\">You are not allowed to view this snippet!</b>");
redirect('/publicsnippets');
} else {
$this->data['snippet'] = $snippet;
}
$this->load->view('dashboard/view_public_snippet', $this->data);
}else{
$this->session->set_flashdata('message', "<b style=\"color:red;\">snippet does not exist</b>");
redirect('/publicsnippets');
}
}
if no row is found in get_snippet method the $snippet will contain false or null
and the second block of condition will run.
In your model change get_snippet() to check for rows:
public function get_snippet($snippet_id) {
$query = $this->db->get_where('snippets', array('id' => $snippet_id));
if ($query->num_rows() > 0) {
return $query->row_array();
} else {
return false;
}
}
Then in your controller:
if ($snippet = $this->dashboard_model->get_snippet($snippet_id)) {
// code if snippet exists
} else {
// code if snippet doesn't exist
}
OR
$snippet = $this->dashboard_model->get_snippet($snippet_id);
if ($snippet) {
// etc...
In CI, I have a model...
<?php
class User_crud extends CI_Model {
var $base_url;
var $category;
var $brand;
var $filter;
var $limit;
var $page_number;
public function __construct($category, $brand, $filter, $limit, $page_number) {
$this->base_url = base_url();
$this->category = $category;
$this->brand = $brand;
$this->filter = $filter;
$this->limit = $limit;
$this->page_number = $page_number;
}
public function get_categories() {
// output
$output = "";
// query
$this->db->select("name");
$this->db->from("categories");
$query = $this->db->get();
// zero
if ($query->num_rows() < 1) {
$output .= "No results found";
return $output;
}
// result
$output .= "<li><a class=\"name\">Categories</a></li>\n";
foreach ($query->result_array as $row) {
$output = "<li>{$row['name']}</li>\n";
}
return $output;
}
while I am calling this in my controller...
<?php
class Pages extends CI_Controller {
// home page
public function home() {
}
// products page
public function products($category = "cell phones", $brand = "all", $filter = "latest") {
// loading
$this->load->model("user_crud");
//
}
Now, How can I pass the $category, $brand and $filter variables to the user_crud model while loading/instantiation?
You shouldn't be using your model like this, just pass the items you need for the functions you require:
$this->load->model("user_crud");
$data['categories'] = $this->user_crud->get_categories($id, $category, $etc);
I would suggest (after seeing your code) that you study the fantastic codeigniter userguide as it has really good examples, and you just went a totally different way (treating model like an object). Its more simple sticking to how it was designed vs what you are doing.
You can not. A better idea would be to setup some setters in your model class along with some private vars and set them after loading the model.
if you return $this from the setters you can even chain them together like $this->your_model->set_var1('test')->set_var2('test2');
I'm using the Cart class in Codeigniter. What I want to do should (hopefully!) be simple... but i'm struggling.
On the product page, I have a button to 'add to cart'. What I want to happen is that when the item is already in the cart, the button changes to 'remove from cart'.
<? //if(**not in cart**) { ?>
Add to cart
<? } else { ?>
Remove from cart
<? } ?>
How can I query the cart to see if that item is in there or not and get the 'rowid' so I can use that for a remove function?
Many thanks!
I had a similar problem - I got round it by extending the CI_Cart library with 2 new functions - in_cart() and all_item_count().
<?php
class MY_Cart extends CI_Cart {
function __construct()
{
parent::__construct();
$this->product_name_rules = '\d\D';
}
/*
* Returns data for products in cart
*
* #param integer $product_id used to fetch only the quantity of a specific product
* #return array|integer $in_cart an array in the form (id => quantity, ....) OR quantity if $product_id is set
*/
public function in_cart($product_id = null) {
if ($this->total_items() > 0)
{
$in_cart = array();
// Fetch data for all products in cart
foreach ($this->contents() AS $item)
{
$in_cart[$item['id']] = $item['qty'];
}
if ($product_id)
{
if (array_key_exists($product_id, $in_cart))
{
return $in_cart[$product_id];
}
return null;
}
else
{
return $in_cart;
}
}
return null;
}
public function all_item_count()
{
$total = 0;
if ($this->total_items() > 0)
{
foreach ($this->contents() AS $item)
{
$total = $item['qty'] + $total;
}
}
return $total;
}
}
/* End of file: MY_Cart.php */
/* Location: ./application/libraries/MY_Cart.php */
You could check in your model if the job name or whatever you would like to check already exists. If it exists display delete button else show add.
