After I have updated a customer (which works fine)
public function update($customer_acc) {
if($this->session->userdata('logged_in'))
{
$id= $this->input->post('did');
$data = array(
'customer_name' => $this->input->post('dname')
);
$this->load->model('update_model');
$this->update_model->update_customer($id,$data);
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
How can i then load back the view customer function. What i need is after the update has been completed so then go back to viewing the customer.
public function view($customer_acc) {
if($this->session->userdata('logged_in'))
{
$this->load->model('display_single_customer');
$customers = $this->display_single_customer->view_single_customer($customer_acc);
$data['customer_acc'] = $customers['customer_acc'];
$data['customer_name'] = $customers['customer_name'];
$this->load->view('customers_single_view', $data);
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
you just exit to another method in your controller to show the new page. for passing the id you can either pass it directly
if ( some condition ) {
$id = $this->input->post('did', TRUE);
// blah blah blah
// success -- now go to show customer method
$this->showCustomer($id) ; }
function showCustomer($id){
// get the customer to display using the $id that was passed
$customers = $this->display_single_customer->view_single_customer($id);
OR you can declare the id with $this-> and then it is available to any method in the controller
$this->id = $this->input->post('did', TRUE);
// blah blah
$this->showCustomer() ; }
function showCustomer(){
// get the customer to display using $this->id
$customers = $this->display_single_customer->view_single_customer($this->id);
// etc etc
I think i may have sussed it I can use a redirect using the $id which is the customer account number
redirect("/customers/view/$id");
Is this the correct way, It works but is it best practice ?

I am working in Codeigniter and I want to hide ID from URL.
my current URL is:
www.localhost/CI/services/1/ac_repair
but need this type of URL in codeigniter:
www.localhost/CI/services/ac_repair
View Page Code:
<?=anchor('services/' . $ser->s_id . '/' . url_title($ser->s_title,'_') ,'View Service');?>
Controller Code:
public function services()
{
$this->load->model('ServicesModel', 'ser_model');
$s_id = $this->uri->segment(2, 0);
if($s_id){
$get_service = $this->ser_model->get_ser($s_id);
return $this->load->view('public/detail', compact('get_service') );
}
else
{
// $services = $this->articles->articles_list( $config['per_page'], $this->uri->segment(3) );
$get_services['result'] = $this->ser_model->all_services_list();
// $this->load->view('public/services', ['services'=>$services]);
$this->load->view('public/services', $get_services);
}
}
Model Code here:
public function get_ser($id)
{
// $q = $this->db
$q = $this->db->select('*')
->from('services')
->where( ['s_id' => $id] )
->get();
if ( $q->num_rows() )
return $q->row();
return false;
}
but need this type of URL in codeigniter:
www.localhost/CI/services/ac_repair
If you want this functionality you have to be able to use your title ac_repair in place of the id. This means the title needs to be marked as unique and therefore not contain any duplicates.
The following pseudo-code should give you an idea:
function services($url_title = null) {
if (!is_null($url_title)) {
// get ser would use title instead of $id
$this->db->where('title', $url_title);
} else {
// all rows
}
}
Other methods would be "hacky" and I cannot think of any off the top of my head that I would consider usable.
Side note: you should never be returning in a view
My website has two restrict areas, in the public website and admin area. I've tried to follow some instructions to make multiple sessions throughout the website, but I'm facing some problems about accessing and retrieving their information.
Below are the login methods from both pages. First from the administration area:
public function login()
{
if ($this->Admin_model->find_credentials()) {
$data['user_email'] = $this->input->post('email');
$this->session->set_userdata('auto', $data);
redirect('/admin/dashboard', 'refresh');
} else {
$this->session->set_flashdata('message', 'Desculpe, credenciais inválidas');
redirect('/admin/entrar');
}
}
And then, the admin area in the public website:
public function login()
{
if ($this->Usuarios_model->find_credentials()) {
$email = $this->input->post('email');
if ($this->Usuarios_model->is_active($email)) {
$data = array();
$data['nome'] = $this->Usuarios_model->find_col_by_email('nome_razao_social', $email);
$data['email'] = $email;
$data['tipo_usuario'] = $this->Usuarios_model->find_col_by_email('tipo_usuario', $email);
$data['id_usuario'] = $this->Usuarios_model->find_col_by_email('id', $email);
$this->session->set_userdata('auto', $data);
$this->session->set_flashdata('message', 'Bem-vindo!');
redirect('/usuario/painel');
} else {
$this->session->set_flashdata('message', 'Por favor, ative o seu cadastro');
redirect('/');
}
} else {
$this->session->set_flashdata('message', 'Desculpe, credenciais inválidas');
redirect('/');
}
}
For each new session, I am settling a name for it. Now, every point I call the session value, I must specify the name of which session I want, but I am having an error message after I try to log-in:
Message: Array to string conversion
This error points at line 161 of my model, which has the following code:
public function find_details($email = null, $id = null, $id_carro = null)
{
$this->db
->select(
'usuario.*,' .
'estado.nome_estado AS uf,' .
'cidade.nome_cidade AS cidade'
)
->join('cidade', 'cidade.id = usuario.id_cidade')
->join('estado', 'estado.id = usuario.id_estado');
if ($email) {$this->db->where('usuario.email', $email);} // 161
...
}
What do I need to do to make multiple sessions work correctly?
Alright. The solution for me was a different way to echo the value of a certain session:
$this->session->userdata('foo')['bar'].
Where foo is the session name, specified when creating a new session. In my case, a good example can be $this->session->userdata('auto')['email'];
I'm using codeigniter, for make an api rest, with the library that provide the oficial web site.
The problem is: the file routes.php doesn't redirect well. When i put localhost/API/1 into my browser apear the 404 error.
Here my controller "Apicontroller":
public function __construct() { //constructor //no tocar
parent::__construct();
$this -> load -> model("Modelocontrolador");
}
public function index_get() { //get all the info
$datos_devueltos = $this->Modelocontrolador->getPrueba(NULL, "Usuarios");
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}
public function find_get($id){ //select where
$datos_devueltos = $this->Modelocontrolador->getPrueba($id, "Usuarios");
if($id != NULL){
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}else{
$this->response(array("response" => "No dates for search"), 200);
}
}
public function index_post() { //insert in la table
if(! $this -> post("dato")){
$this->response(array("response" => "No enought info"), 200);
}else{
$datoID = $this -> Modelocontrolador -> save($this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => $datoID), 200);
}else{
$this->response(array("response" => "No found it"), 200);
}
}
}
public function index_put($id) { //"update"
if(! $this -> post("dato") || ! $id){
$this->response(array("response" => "No ha mandado informacion correcta para el update"), 200);
}else{
$datoID = $this -> Modelocontrolador -> update("Uid",$id,$this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => "Dato actualizado"), 200);
}else{
$this->response(array("response" => "Error modify"), 200);
}
}
}
public function index_delete($id) {
if(! $id){
$this->response(array("response" => "Not enought info"), 200);
}else{
$delete = $this-> Modelocontrolador -> delete("Uid",$id,"UsuariosJJ");
}
if(!is_null($delete)){
$this->response(array("response" => "Date delete"), 200);
}else{
$this->response(array("response" => "Error delete"), 200);
}
}}
And my routes file:
$route['default_controller'] = 'Apicontroller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
/*sub-rutas*/
/*---------*/
$route["Apicontroller"]["get"] = "Apicontroller/index"; //basico
$route["Apicontroller/(:num)"]["get"] = "Apicontroller/find"; //select
$route["Apicontroller"]["post"] = "Apicontroller/index"; //insert
$route["Apicontroller/(:num)"]["put"] = "Apicontroller/index/$1"; //update
$route["Apicontroller/(:num)"]["delete"] = "Apicontroller/index/$1"; //delete
If the browser request literally uses /API then routing needs to 'see' exactly that. Also, the route rules must be explicit with the method to be called. (Hopefully the code shown reflects the mapping you had in mind.)
/*sub-rutas*/
/*---------*/
$route["API"]["get"] = "Apicontroller/index_get"; //basico
$route["API/(:num)"]["get"] = "Apicontroller/find_get/$1"; //select
$route["API"]["post"] = "Apicontroller/index_post"; //insert
$route["API/(:num)"]["put"] = "Apicontroller/index_put/$1"; //update
$route["API/(:num)"]["delete"] = "Apicontroller/index_delete/$1"; //delete
Using the above routes I created some test code. Here are those files.
The much simplified Apicontroller.
class Apicontroller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
function index_get()
{
echo "API index";
}
public function find_get($id)
{ //select where
echo "API find_get $id";
}
public function index_post()
{
echo 'API index_post';
}
public function index_put($id)
{ //"update"
echo "API put $id";
}
}
I don't believe that because your Apicontroller is extending a different Class the results would change. That may be a drastic assumption.
In order to test POST calls I used these two files.
First a Testpost.php controller
class Testpost extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('form');
}
public function index()
{
$this->load->view("test");
}
}
The very simple view (test.php) loaded by the above.
<?php
echo form_open("API");
echo form_submit('mysubmit', 'Submit Post!');
echo form_close();
Directing the browser to localhost/testpost shows a page with a single submit button. Pressing the button results in a screen with the text "API index_post".
Sending the browser to localhost/API/3 produces a screen with the text "API find_get 3".
localhost/API produces "API index".
Now the interesting thing (not related to your problem, but interesting).
Given the default
$route['default_controller'] = 'Apicontroller';
and the route
$route["API"]["get"] = "Apicontroller/index_get";
I expected that directing the browser to the home page localhost would produce "API index". But it doesn't. It results in a 404. Due to that behavior it might be wise to be more explicit with default_controller
$route['default_controller'] = 'Apicontroller/index_get';
Or add an index() function to Apicontroller that calls $this->index_get().
I did not test PUT or DELETE as my server isn't setup to handle them. But as GET and POST seem to function, in a righteous world, they will work.
seems like you are using PHil's REST_Controller library with CI 2.x, correct ?
If so, I would recommend you to use what I like to call an "index gateway" because you can't do per-Method routing with CI2:
class Apicontroller extends REST_Controller
{
function index_gateway_get($id){
$this->get_get($id);
}
function index_gateway_put($id){
$this->put_put($id);
}
// This is not a "gateway" method because POST doesn't require an ID
function index_post(){
$this->post_post();
}
function get_get($id = null){
if(!isset($id)){
// Get all rows
}else{
// Get specific row
}
}
function put_put($id = null){
if(!isset($id)){
// a PUT withtout an ID is a POST
$this->post_post();
}else{
// PUT method
}
}
function post_post(){
// POST method
}
}
The routing to make this work is really easy:
$route["API/(:num)"] = "Apicontroller/index_gateway/$1";
That's all you need. Phil's REST Library will redirect to the correct index_gateway_HTTPMETHOD depending on which method is used.
Each index_gateway_HTTPMETHOD will then redirect to the correct method.
As far as I know, this trick is the only way to have CI2 use a single /API/ entry point that works for all HTTP Methods.
Here is my controller code
function index() {
echo $this->session->flashdata('message');
$this->load->view('categoryView');
}
function delete() {
$products = $this->item_model->get_category_id($category_id);
if (count($products)) {
$message = 'Category Name is used by the product. Please change them to another category!';
}
else {
$category_id = $this->product_category_model->delete($category_id);
$message = ($category_id) ? 'Category Deleted Successfully' : 'Failed to Delete Category';
}
$this->session->set_flashdata('message', $message);
redirect('category', 'refresh');
}
After calling the delete function the flashdata has to be set and retrieve that value in index() function of the same controller but I can't.
Am also tried the $this->session->keep_flashdata('message'); before redirect to index function. But still am not get any value in index function.
Also changed $config['sess_expire_on_close'] = FALSE; to $config['sess_expire_on_close'] = TRUE; Still am not get the result.
I am wasted more time(nearly half day). Please anybody help to retrieve the flas data in codeigniter.
There are several probabilities:
1- Check your browser cookie. See if it allows cookies or if any other extension is intervening.
2- Refresh might not send the browser a new request (which thus mean a new URL). Try it for another controller see if it make any change
3- hard code the set_flashdata() with hard-coded value than a variable. set_flashdata("message", "Thank you");
In codeingitor you cannot echo anything in controller.
You have to set in $this->session->flashdata('message'); in view file not in index() function of controller
Try again by putting $this->session->flashdata('message'); in "categoryView" file where you want to display flash message.
You could try:
function set_flashdata_notification($notify_type, $msg, $error_code = null)
{
$ci =& get_instance();
$flashdata_data = set_notification_array($notify_type, $msg, $error_code);
$ci->session->set_flashdata($flashdata_data);
}
function delete() {
$products = $this->item_model->get_category_id($category_id);
if (count($products)) {
set_flashdata_notification('Category Name is used by the product.','Please change them to another category!');
redirect('path_to_view/view','refresh');
}
I have this code in my controller (admin):
function save(){
$model = $this->getModel('mymodel');
if ($model->store($post)) {
$msg = JText::_( 'Yes!' );
} else {
$msg = JText::_( 'Error :(' );
}
$link = 'index.php?option=com_mycomponent&view=myview';
$this->setRedirect($link, $msg);
}
In model I have:
function store(){
$row =& $this->getTable();
$data = JRequest::get('post');
if(strlen($data['fl'])!=0){
return false;
}
[...]
And this is working - generate error message, but it return to items list view. I want to stay in edit view with entered data. How to do it?
In your controller you can:
if ($model->store($post)) {
$msg = JText::_( 'Yes!' );
} else {
// stores the data in your session
$app->setUserState('com_mycomponent.edit.mymodel.data', $validData);
// Redirect to the edit view
$msg = JText::_( 'Error :(' );
$this->setError('Save failed', $model->getError()));
$this->setMessage($this->getError(), 'error');
$this->setRedirect(JRoute::_('index.php?option=com_mycomponent&view=myview&id=XX'), false));
}
then, you will need to load the data from session with something like:
JFactory::getApplication()->getUserState('com_mycomponent.edit.mymodel.data', array());
normally this is loaded in the method "loadFormData" in your model. Where to load that data will depend on how are you implementing your component. If you are using the Joomla's form api then you can add the following method to your model.
protected function loadFormData()
{
// Check the session for previously entered form data.
$data = JFactory::getApplication()->getUserState('com_mycomponent.edit.mymodel.data', array());
if (empty($data)) {
$data = $this->getItem();
}
return $data;
}
EDIT:
BUT please note, that Joomla's API already can do all this for you if you controller inherits from "JControllerForm", you don't need to rewrite the save method. The best way to create your component is copying what is in Joomla's core components, com_content for example
It is not recommended to rewrite save or any method.
If you really want to override something and want to update something before or after save, you should use JTable file.
For Example:
/**
* Example table
*/
class HelloworldTableExample extends JTable
{
/**
* Method to store a node in the database table.
*
* #param boolean $updateNulls True to update fields even if they are null.
*
* #return boolean True on success.
*/
public function store($updateNulls = false)
{
// This change is before save
$this->name = str_replace(' ', '_', $this->name);
if (!parent::store($updateNulls))
{
return false;
}
// This function will be called after saving table
AnotherClass::functionIsCallingAfterSaving();
}
}
You can extends any method using JTable class and that's the recommended way to doing it.
