I'm trying to send a simple ajax request in cakephp. I've to send ajax requests for many buttons. But I'm just trying a simple ajax request first. But it's not working for some reason. This is what I've done so far. This is my code.
show.ctp
<?php echo $this->Html->script('jquery', FALSE); ?>
<?php
echo $this->Form->create();
echo $this->Form->input('field', array('id'=>'field'));
echo $this->Js->submit('Send', array(
'before'=>$this->Js->get('#sending')->effect('fadeIn'),
'success'=>$this->Js->get('#sending')->effect('fadeOut'),
'update'=>'#success'
));
?>
<div id='sending' style="display:none"> Counz[dot]gif will be displayed </div>
<div id='success'></div>
controller
var $name = 'count';
public $helpers = array('Js' => array('Jquery'));
//var $helpers = array('Ajax', 'Javascript');
var $components = array('RequestHandler');
public function show(){
if($this->RequestHandler->isAjax()){
$this->render('success', 'ajax'); //ajax tells the layout it should use
}else{
$this->set('for_map', $this->count->find('all'));
}
}
success.ctp
<p>It's working</p>
Also ajax.ctp is there by default.
Please tell me what am I doing wrong. Thanks. :)
It's better not to post to self when doing ajax requests.
show.ctp
echo $this->Form->create('Count', array('action'=>'ajaxShow'));
controller
public function ajaxShow(){
$this->layout = 'ajax';
if($this->RequestHandler->isAjax()){
$this->render('success', 'ajax'); //ajax tells the layout it should use
}
}
I know this thread is very old but I'll just share my answer. You can just do normal ajax call, for example your url is 'users/items' type is GET then in your:
UsersController.php
public function items(){
// some logic to get items
$this->set('items',$items);
$this->layout = null; //remove default layout.
$this->render('ajax/items'); // here I use View/Users/ajax/items.ctp
}
items.ctp
//you can return json
<?php echo json_encode($items); ?>
//or
//your own format
<?php
foreach($items as $item){
//some output
}
?>
now that output in items.ctp will be in your js' success property. just make sure you parse the returned json.

i have been trying to redirect the same previous page after delete or inserting the data using if condition in the controller to flash the message but there is something i am missing.
<form action="<?php echo base_url(); ?>curdler/add/tbl_category/addCat/category" method="post">
Category Title<input type="text" name="category_title"/> </br>
<input type ="submit" value="submit">
</form>
<?php echo $this->session->flashdata('msg'); ?>
Controller
public function add() {
$data = $_POST;
$tableName = $this->uri->segment(3);
$content = $this->uri->segment(4);
$folderName = $this->uri->segment(5);
$this->load->model('curdmodel');
if($this->curdmodel->add($data, $tableName)){
$this->session->set_flashdata('msg', 'Category added');
redirect('welcome/index/'.$content.'/'.$folderName);
} else{
$this->session->set_flashdata('msg', 'Category Not Added');
}
}
when using the if statement it goes to the different url but without if statement its working fine.
model
public function add($data, $tableName) {
$this->db->insert($tableName, $data);
}
Your redirect only occurs if the if statement evaluates to be true, if the condition is false codeigniter is just setting the flashdata and then ending the script.
Consider changing the order of your code to something like
if($this->curdmodel->add($data, $tableName)){
$this->session->set_flashdata('msg', 'Category added');
} else{
$this->session->set_flashdata('msg', 'Category Not Added');
}
redirect('welcome/index/'.$content.'/'.$folderName);
Additionally, your model does not contain any return value and therefore will never pass data back for the if statement to be evaluated. You should update your model as follows:
public function add($data, $tableName) {
$this->db->insert($tableName, $data);
if($this->db->affected_rows() > 0) {
return true;
}
}
i have the following code which i modiefied from a tutorial
but the problem is that, i cant display the result properly in my view page..
if i display the array in the controller then its working properly, but in the view, its throwing the error..
<?php
class test extends CI_Controller {
public function index($start = 0) {
$this->load->model('pages_model');
$data_page=$this->pages_model->get_pages();
$this->load->helper('url');
$this->load->library('pagination');
$config['base_url'] = base_url().'test/index';
$config['total_rows'] = count($data_page);
$config['per_page'] = 5;
$data['user'] = array();
for($i=$start; $i<$start+$config['per_page']; $i++)
{
if (isset($data_page[$i])) {
$data['user'] = $data_page[$i];
}
}
//print_r($data['user']['page_id']); // this line displays 3, since the tupple with id 3 has maximum priority 5
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
if ($this->input->post('ajax')) {
$this->load->view('test', $data);
} else {
$this->load->view('test', $data);
}
}
}
?>
now comes the model
<?php
class pages_model extends CI_Model{
function __construct() {
parent::__construct();
}
function get_pages()
{
return $this->db->query("SELECT * FROM td_pages ORDER BY page_priority ASC")->result_array();
}
}
?>
and finally the view
<!DOCTYPE html>
<html>
<header>
<title>CodeIgniter Ajax Jquery Pagination</title>
<script src="<?php echo base_url(); ?>assets/front_assets/js/jquery-1.7.1.min.js"></script>
<script>
$(function() {
applyPagination();
function applyPagination() {
$("#ajax_paging a").click(function() {
var url = $(this).attr("href");
$.ajax({
type: "POST",
data: "ajax=1",
url: url,
beforeSend: function() {
$("#content").html("");
},
success: function(msg) {
$("#content").html(msg);
applyPagination();
}
});
return false;
});
}
});
</script>
</header>
<body>
<div id="content">
<div id="data">
<?php foreach($page_frag as $ut)
{?>
<div><?php echo $ut['page_slug'];?></div>
<?php } ?>
</data>
<div id="ajax_paging">
<?php echo $pagination; ?>
</div>
</div>
</div>
</body>
</html>
the problem is that the view is displaying the results in wrong way, but if i display in controller, then it shows that the array in the controller is working perfectly...
please help me solving the prob
You are loading the entire view in your ajax request which also contains the body and head text, Create a seperate view with the following content and load it in your ajax request.
<div id="data">
<?php foreach($page_frag as $ut)
{?>
<div><?php echo $ut['page_slug'];?></div>
<?php } ?>
</div>
What you're doing is WRONG
Pagination is meant to off-load processing power/ram from the server not only from the client side.
You're pulling off all your result then paginate them while you should be asking MySQL to paginate it for you & have a second query to give you the number of results to use it.
If you have index.php in your links then you must be using site_url() instead of base_url() & please note that both accepts an argument so you do not need to concatenate it the way you did it would be like this:
site_url('test/index');
codeigniter uses GET method, while in your javascript code you're using POST.
An easier method would be to catch the pagination li > a tags for the pagination & process it inside a container.
How can i use flash messenger in zend freamwork 2? Session documentation is not yet. Anyone know it? But session libraries are there.
Update :
Zend Framework new release added FlashMessenger View Helper , found in path /library/Zend/View/Helper/FlashMessenger.php
FlashMessenger.php
Old answer :
I have written a custom view helper, for printing flash messages
In /module/Application/Module.php
public function getViewHelperConfig()
{
return array(
'factories' => array(
'flashMessage' => function($sm) {
$flashmessenger = $sm->getServiceLocator()
->get('ControllerPluginManager')
->get('flashmessenger');
$message = new \My\View\Helper\FlashMessages( ) ;
$message->setFlashMessenger( $flashmessenger );
return $message ;
}
),
);
}
Create a custom view helper in /library/My/View/Helper/FlashMessages.php
namespace My\View\Helper;
use Zend\View\Helper\AbstractHelper;
class FlashMessages extends AbstractHelper
{
protected $flashMessenger;
public function setFlashMessenger( $flashMessenger )
{
$this->flashMessenger = $flashMessenger ;
}
public function __invoke( )
{
$namespaces = array(
'error' ,'success',
'info','warning'
);
// messages as string
$messageString = '';
foreach ( $namespaces as $ns ) {
$this->flashMessenger->setNamespace( $ns );
$messages = array_merge(
$this->flashMessenger->getMessages(),
$this->flashMessenger->getCurrentMessages()
);
if ( ! $messages ) continue;
$messageString .= "<div class='$ns'>"
. implode( '<br />', $messages )
.'</div>';
}
return $messageString ;
}
}
then simple call from layout.phtml , or your view.phtml
echo $this->flashMessage();
Let me show example of controller action
public function testFlashAction()
{
//set flash message
$this->flashMessenger()->setNamespace('warning')
->addMessage('Mail sending failed!');
//set flash message
$this->flashMessenger()->setNamespace('success')
->addMessage('Data added successfully');
// redirect to home page
return $this->redirect()->toUrl('/');
}
In home page, it prints
<div class="success">Data added successfully</div>
<div class="warning">Mail sending failed!</div>
Hope this will helps !
i have written a post about this some time ago. You can find it right here
Basically you use it just the same like earlier.
<?php
public function commentAction()
{
// ... display Form
// ... validate the Form
if ($form->isValid()) {
// try-catch passing data to database
$this->flashMessenger()->addMessage('Thank you for your comment!');
return $this->redirect()->toRoute('blog-details'); //id, blabla
}
}
public function detailsAction()
{
// Grab the Blog with given ID
// Grab all Comments for this blog
// Assign the view Variables
return array(
'blog' => $blog,
'comments' => $comments,
'flashMessages' => $this->flashMessenger()->getMessages()
);
}
Then in your .phtml file you do it like this:
// details.phtml
<?php if(count($flashMessages)) : ?>
<ul>
<?php foreach ($flashMessages as $msg) : ?>
<li><?php echo $msg; ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
Obviously this isn't all too handy, as you have to do this for every single .phtml file. Therefore doing it within the layout you have to do it at best like the following:
<?php
// layout.phtml
// First get the viewmodel and all its children (ie the actions viewmodel)
$children = $this->viewModel()
->getCurrent()
->getChildren();
$ourView = $children[0];
if (isset($ourView->flashMessages) && count($ourView->flashMessages)) : ?>
<ul class="flashMessages">
<?php foreach ($ourView->flashMessages as $fMessage) : ?>
<li><?php echo $fMessage; ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
If you need further description, please see my blog, but i guess the code itself is pretty clear (apart frmo the layout.phtml example). Alternatively you're always free to write your own view helper to have it look a little cleaner inside your view-templates.
How to grab Flashmessenger’s messages in a View Helper – sharing code as requested by Sam.
The View helper should implement the ServiceManagerAwareInterface interface and related methods. The plugin will now have access to a Service Manager which we can use to get the Service Locator and ultimately access to the Flash Messenger.
I’ve not touched this code since I initially wrote it – so there may be a more elegant way of doing this.
protected function getMessages()
{
$serviceLocator = $this->getServiceManager()->getServiceLocator();
$plugin = $serviceLocator->get('ControllerPluginManager');
$flashMessenger = $plugin->get('flashmessenger');
$messages = $flashMessenger->getMessages();
// Check for any recently added messages
if ($flashMessenger->hasCurrentMessages())
{
$messages += $flashMessenger->getCurrentMessages();
$flashMessenger->clearCurrentMessages();
}
return $messages;
}
And calling getMessages() from within the plugin should return an array of messages that can be passed to a partial and rendered.
Add code below to the view to render error messages:
<?php echo $this->flashmessenger()
->setMessageOpenFormat('<div class="alert alert-danger"><ul%s><li>')
->setMessageCloseString('</li></ul></div>')
->render('error')
; ?>
In previous request, make sure you created an error message by running code below in your controller:
$this->flashmessenger()->addErrorMessage('Whops, something went wrong...');
I am a newbie in CI. I used MY_Controller.php as main controller. I could open the ajax as the div#page loader. Now , My problem is although I load /about page, I get the database entries for the services model. How can i get the about table for the about controller ?
..
function render_page($view) {
if( ! $this->input->is_ajax_request() )
{
$this->load->view('templates/header', $this->data);
}
$this->load->view($view, $this->data);
if( ! $this->input->is_ajax_request() )
{
$this->load->view('templates/menu');
$this->load->view('templates/footer', $this->data);
}
}..
My services_model:
class Services_model extends CI_Model {
function getAll() {
$q = $this->db->get('services');
if($q->num_rows() > 0){
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
}
My home controller :
public function view($page = 'home')
{
$this->load->helper('text');
$this->data['records']= $this->services_model->getAll();
if ( ! file_exists('application/views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->render_page('pages/'.$page,$data);
}
When I use them in the home view there is no problem I can see the services_table :
<ul class="blog-medium">
<?php foreach($records as $row): ?>
<li>
<div class="blog-medium-text">
<h1><?php echo $row->title; ?></h1>
<p class="blog-medium-excerpt"><?php echo $row->content; ?><br />
Devamını Okumak için →</p>
</div>
<?php endforeach ?>
I want to use the same way in about page.
About_model:
class About_model extends CI_Model {
function getAll() {
$q = $this->db->get('abouts');
if($q->num_rows() > 0){
foreach ($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
}
About controller :
public function view($page = 'about')
{
$this->load->helper('text');
$this->data['records']= $this->about_model->getAll();
if ( ! file_exists('application/views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->render_page('pages/'.$page,$data);
}
And this is my view file of about :
<div id="content">
<?php foreach($infos as $row): ?>
<h3 style="text-align: center;"> <?php echo $row->title; ?></h3>
<div class="hr"> </div>
<?php echo $row->content; ?>
<?php endforeach; ?>
I get the error telling me :
Severity: Notice
Message: Undefined variable: infos
Filename: pages/about.php
Line Number: 3
Why cant i get the abouts table?
You are calling a variable $infos in your foreach, but it is never passed in as a variable to your view.
Read the docs about Adding Dynamic Data to the View
You will either need to set $data['infos'] to something or, and I'm guessing this what you intended, use $records in your foreach
The above answers your specific, but after you provided the repo for your source, there are issues you are struggling with. I highly suggest you read through the entire documentation, staring with the Introduction: Getting Started, continuing to the Tutorials and then General Topics.
The reason you are having problems here, you have your routes.php setup to that everything is routed into the Home controller executing the view method. This method, while it accepts the page you want to see is always returning a fetch of the services model. Your other controllers are not getting executed at all. Based on your controller setup, if you would just remove the custom route, http://theurl/about would route to the About Controller. The default method to be loaded is index so if you change view to index, then it would be displayed by default.
Could you please tell me how my model,controller and view should look like if I want to pass the following variable data($amount1, $amount2, $amount3) to my view file via controller from my model.
case 1: $amount1=100;
case 2: $amount2=500;
case 3: $amount3=1000;
I want to have the variables in a way that I don't have to echo them in any { } example:
foreach ($records as $row){ $i++; ?>
// I don't want to echo those inside in this.
// I want to echo it like this way- <? echo $amount1;?>
}
Thanks in Advance :)
If you pass an array of data from your controller to your view you can access each element as a variable in the view. Here is an example of what I mean:
model:
class Model extends CI_Model
{
public function get_data()
{
$data = array(
'amount1' => 100,
'amount2' => 500,
'amount3' => 1000,
);
return $data;
}
}
controller:
class Controller extends CI_Controller
{
public function index()
{
// get data from model
$data = $this->model->get_data();
// load view
$this->load->view('view', $data);
}
}
view:
<h1><?php echo $amount1; ?></h2>
<p><?php echo $amount2; ?></p>
<!-- etc... -->
I have found a solution myself. I just wanted to share so that it can help others. So here it is..
Your model should look like following :
function net_income(){
$data['amount1']=50;
$data['amount2']=100;
return json_encode($data);
}
Your controller:
function add(){
$this->load->model('mod_net_income');
$json = $this->mod_net_income->net_income();
$obj = json_decode($json);
$data['amount1']= $obj->{'amount1'};
$this->load->view('your_viewfile_name',$data);
}
And then in your view file: just
<? echo "$amount" ; ?>
Thanks :)
