Posting to controller with jquery ajax in CakePHP - php

Question

I want to post data to a controller in CakePHP, but posting with JQuery always results in an error and I can't figure out why.
In my view I have the following method, that posts the data to the controller page
function RenameNode(name, id)
{
$.ajax({
type: "POST",
url: '<?php echo Router::url(array('controller' => 'categories', 'action' => 'rename')); ?>',
data: {
id: id,
name: name
},
success: function(){
}
});
}
My controller method looks like this:
public function rename($id = null, $name = null) {
if ($this->request->is('get')) {
throw new MethodNotAllowedException();
}
if(!$id)
{
$id = #$this->request->query('id');
}
if(!$name)
{
$name = #$this->request->query('name');
}
if (!$id) {
throw new NotFoundException(__('No id'));
}
$category = $this->Category->findById($id);
if (!$category) {
throw new NotFoundException(__('Invalid category'));
}
$this->autoRender = false;
$this->layout = 'ajax';
if ($this->request->is('post') || $this->request->is('put')) {
$this->Category->id = $id;
$this->request->data['Category']['name'] = $name;
if ($this->Category->save($this->request->data)) {
$this->Session->setFlash(__('The category has been updated.'));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('Unable to update the category.'));
}
}
}
When I do a post with the jquery method, I keep getting the following error message in my log:
2013-05-20 11:34:25 Error: [NotFoundException] No id
Request URL: /cakephp/categories/rename
Stack Trace:
#0 [internal function]: CategoriesController->rename()
When I comment the request checks for get and post, the controller itself works perfectly when I call it with /categories/rename?id=1&name=test. For some reason the ajax way doesn't work, but I can't figure out why. Any ideas?
Update
I fixed it by changing the following code, now it works perfectly
if(!$id)
{
$id = #$this->request->query('id');
}
if(!$name)
{
$name = #$this->request->query('name');
}
to
if(!$id)
{
$id = #$this->request->data('id');
}
if(!$name)
{
$name = #$this->request->data('name');
}

Answer 1

You are not including the id and/or name in the URL you're posting to;
echo Router::url(array('controller' => 'categories', 'action' => 'rename'));
Will output;
/categories/rename
But you're expecting
/categories/rename/1/test
Or
/categories/rename?id=1&name=test
Change the URL in your AJAX code to something like;
echo Router::url(array(
'controller' => 'categories',
'action' => 'rename',
0 => $this->request->params['pass'][0],
1 => $this->request->params['pass'][1]
));
Which should output the right url, containing the original id and name of the current request (e.g. /categories/rename/123/oldname)

Answer 2

use somthing like that
data = 'name='+name+'&id='id'';
$.ajax({
type:'post',
url: '/categories/rename',
data: data
});
and in controller function
$name=$_POST[name];
$id=$_POST[id];

$('a.ajax-delete-pdf').on('click', function (event) {
event.preventDefault();
var id = $(this).data('id');
$.ajax(
{
url: webroot + 'productos/ajax_eliminar_pdf/' + id ,
async : false,
success: function(respuesta)
{
if(respuesta == 'Borrado')
{
$(this).parent().toggle();
}
}
});
});
