I'm using CakePHP 3 and I want to paginate my users.
However when I click on the second page, the URL looks like /users?page=2 and I expect : /users/2.
I created this route in routes.php :
$routes->connect('/users/:page', ['controller' => 'users', 'action' => 'index'], ['page' => '[0-9]+']);
And in Users/index.ctp before the "prev" button I put :
<?php
$this->Paginator->options([
'url' => [
'controller' => 'users',
'action' => 'index'
]
]);
?>
Now when I click on page 2 for example, /users/2 opens and I got this error message (RuntimeException) :
Unable to locate an object compatible with paginate.
Did I miss something or where I made a mistake ?
Thanks for your help.
The PaginatorHelper has built in the url format, i.e. to use ?page=n. It will also do sorting such as users?page=2&sort=user_id&direction=asc. Your format of /users/{page} does not handle sorting.
If your REALLY want to stick to /users/{page} you'll have to override PaginatorHelper.
try this
in side your controller with paginator component . It works for me
$this->Paginator->paginate('Users')
for custom urlenter code here
u need to implement index action as
public function index($page = null){
$this->Paginator->settings = ['limit' => 15, 'page' => $page];
$this->set('users', $this->Paginator->paginate('Users'));
}

I'm new to CakePHP...
Can anyone help me about this:
I have a Controller that I want to maintain in the URL not search an action, i.e: site.com/controller/SKU01B not seek for action SQU01B but search by product with SKU, the same will occur when typed site.com/product/view/1.
I think:
$routes->connect('/site/SKU*', ['controller' => 'Site', 'action' => 'index']);
but it didn't work, nor with ? instead of *.
Can anyone help me how can I do it?
Use:
Router::connect('/sku/*', array('controller' => 'yourcontroller', 'action' => 'view'),array('pass' => array('id')));
and
function view($id=null){
// $id will be sku
// For example, http://www.example.com/product/12345 here $id is 12345
}
Recently, I've been studying cake, I've seen the auth library which said to be will take care of the access control over your app, but, it seems like, you can't initialize or even use this auth library when you're not in the 'UsersController', i did not want that, what if it has some admin part wherein i want the URI to be admin/login, or just simply /login, i've been scratching my head over this one, please help.
Another question, why it seems like the functionality of the '$this->redirect' is not effective when i'm putting this one at any method that contains nothing but redirection, or even in the __construct()?
thanks guys, hoping someone could clearly explain to me those things.
you can use the Auth component inside any controller in the application. If you want it will only effect with the admin section then you can add condition in the beforeFilter funciton in you application AppController on Auth initialization like.
// for component initialization.
public $components = array(
'Auth' => array(
'authenticate' => array(
'userModel' => 'Customer', // you can also specify the differnt model instead of user
'Form' => array(
'fields' => array('username' => 'email')
)
)
)
}
and you can bind this on the admin routing like
function beforeFilter(){
// only works with admin routing.
if(isset($this->request->params['prefix']) && ($this->request->params['prefix'] == 'admin')){
$this->Auth->loginRedirect = array('admin' => true, 'controller' => 'pages', 'action' => 'index');
$this->Auth->logoutRedirect = array('controller' => 'users', 'action' => 'login', 'admin' => true);
$this->Auth->loginAction = array('admin' => true, 'controller' => 'customers', 'action' => 'login');
}
}
If you're using cake 2.3.x or later then make sure you have specified the redirect action in correct format like.
return $this->redirect('action_name'); // you can also specify the array of parameters.
I have some simple pagination set up in my controller like so:
public function index() {
$this->set('items', $this->paginate());
}
In my view I'm using the Paginator helper to output numbered links:
echo $this->Paginator->numbers(array(
'separator' => '',
'tag' => 'li',
'currentTag' => 'a',
'currentClass' => 'active'
));
This all works fine, however I want to use a custom URL for the paginated links. I added this to my routes.php file:
Router::connect('/things/:page', array('controller' => 'things', 'action' => 'index'), array('page' => '[0-9]+'));
Now the links outputted by the Paginator helper are the way I want. They look like http://mysite.com/things/2, http://mysite.com/things/3 etc.
But when I click the links the Paginator in my controller doesn't seem to recognize it's on a certain page, as I just get the first page's results shown. I'm guessing I need to somehow pass the page number to $this->paginate(), but I don't know what the best method is. Is there a way for Cake to get the page number automatically if I modify my route?
Thanks!
Since the Pagination component by default expect named parameter 'page:1' you need somehow to pass same variable in index.
if you make print of $this->request->params in your controller, you will see that it's missing.
See that example how you can pass named parameters in the Router:
Router::connect(
'/:controller/:action/*',
array(),
array(
'named' => array(
'wibble',
'fish' => array('action' => 'index'),
'fizz' => array('controller' => array('comments', 'other')),
'buzz' => 'val-[\d]+'
)
)
);

I obviously have a fundamental misunderstanding of how pagination works in CakePHP.
I have the following route set up which shows all posts in a category:
Router::connect('/:parent/:category',
array('controller' => 'posts', 'action' => 'viewCategory'),
array('parent' => '[a-z0-9-]+', 'category' => '[a-z0-9-]+'));
The pages work fine, however the pagination helper is outputting the wrong links for pagination.
I'm using $this->Paginator->numbers().
It's outputting links in this format: mysite.com/posts/viewCategory?page=2
rather than like this: mysite.com/parent-category/sub-category?page=2.
I've tried adding the following route after the first one and it still doesn't work:
Router::connect('/:parent/:category/:page',
array('controller' => 'posts', 'action' => 'viewCategory'),
array('parent' => '[a-z0-9-]+',
'category' => '[a-z0-9-]+',
'page' => '[0-9]+'));
For reference, my pagination options set in my view are as so:
<?php $this->Paginator->options(
array('url' =>
array('controller' => 'posts', 'action' => 'viewCategory')
)); ?>
What am I doing wrong here?
You are setting the url yourself
This is your paginator options call:
<?php
$this->Paginator->options(array(
'url' => array(
'controller' => 'posts',
'action' => 'viewCategory'
)
));
?>
Where you are overriding the current url - and explicitly requesting that the paginator uses the the '/posts/viewCategory' url (with no arguments) as it's base url.
Just don't define the url
Simply don't call options and the helper will use the current url - that should mean that if the current url is:
/parent-category/sub-category
Then page 2 will be (assuming you are using the paramType option to use GET arguments rather than named parameters):
/parent-category/sub-category?page=2
If that's not the case there's information missing from the question; it's important to distinguish between "vanity routes not being used" and "the url is not equivalent (the current situation).
Just had a battle fixing something similar and came across this post. Though old, but I think my answer might save someone the time I had to spend fixing it.
Basically, what you need to do is call the Paginator->options() before Paginator->numbers(), thus:
$this->Paginator->options(
array(
'controller' => 'parent-category',
'action' => 'sub-category'
)
);
Though the controller and action do not exist, it just tricks CakePHP to use them "AS IS", since the reverse routing isn't working!
And for those (like me), who want have set up a route similar to
Router::connect(
'/go/page:id',
array(
'controller' => 'blog',
'action' => 'paginated'
)
);
There might be difficulty setting up the Paginator options. This, however, worked for me:
$this->Paginator->options(
array(
'controller' => 'go',
'action' => '/'
)
);
I guess you know why it worked ;)
I have one route that looks like this:
Router::connect('/Album/:slug/:id',array('controller' => 'albums', 'action' => 'photo'),array('pass' => array('slug','id'),'id' => '[0-9]+'));
and another like this:
Router::connect('/Album/:slug/*',array('controller' => 'albums','action' => 'contents'),array('pass' => array('slug')));
for what doesn't match the first. In the 'contents' action of the 'albums' controller, I take care of pagination myself - meaning I retrieve the named parameter 'page'.
A URL for the second route would look like this:
http://somesite.com/Album/foo-bar/page:2
The Above URL indeed works, but when I try to use the HTML Helper (url,link) to output a url like this, it appends the controller and action to the beginning, like this:
http://somesite.com/albums/contents/Album/foo-bar/page:2
Which i don't like.
The code that uses the HtmlHelper is as such:
$html->url(array('/Album/' . $album['Album']['slug'] . '/page:' . $next))
See below url it is very help full to you
http://book.cakephp.org/2.0/en/development/routing.html
Or read it
Passing parameters to action
When connecting routes using Route elements you may want to have routed elements be passed arguments instead. By using the 3rd argument of Router::connect() you can define which route elements should also be made available as passed arguments:
<?php
// SomeController.php
public function view($articleId = null, $slug = null) {
// some code here...
}
// routes.php
Router::connect(
'/blog/:id-:slug', // E.g. /blog/3-CakePHP_Rocks
array('controller' => 'blog', 'action' => 'view'),
array(
// order matters since this will simply map ":id" to $articleId in your action
'pass' => array('id', 'slug'),
'id' => '[0-9]+'
)
);
And now, thanks to the reverse routing capabilities, you can pass in the url array like below and Cake will know how to form the URL as defined in the routes:
// view.ctp
// this will return a link to /blog/3-CakePHP_Rocks
<?php
echo $this->Html->link('CakePHP Rocks', array(
'controller' => 'blog',
'action' => 'view',
'id' => 3,
'slug' => 'CakePHP_Rocks'
));
