I am trying to add CakeDC ratings to my CakePHP website. I have followed the instructions in readme provided with the plugin, but the rating stars do not appear. Also the ratings are not saved when I press 'Rate'. Here is the code from the view file:
<h3><?php echo ($post['Post']['title']); ?></h3>
<?php echo $this->Rating->display(array(
'item' => $post['Post']['id'],
'type' => 'radio',
'stars' => 5,
'value' => $post['Post']['rating'],
'createForm' => array('url' => array_merge($this -> passedArgs, array('rate' => $post['Post']['id'], 'redirect' => true)))));?></h3>
After pressing "Rate", the url changes to '.../rate:2/redirect:1' , but the data does not appear in the database. Am I missing something?
i also encountered this problem, but what i did was, i added this
public $components = array('Ratings.Ratings');
public $actsAs = array('Ratings.Ratable');
and after that, it managed to save the data

I'm trying to display data in cakePHP with a Google Chart.
I downloaded the GoogleCharts plugin on https://github.com/scottharwell/GoogleCharts and put it in my App/Plugin directory. I load all plugins in my application's bootstrap file with
CakePlugin::loadAll();
In my Controller, I put
App::uses('GoogleCharts', 'GoogleCharts.Lib');
and
public $helpers = array('GoogleCharts.GoogleCharts');
, so cakePHP is able to detect I will work with this plugin. Of course, I created the GoogleChartHelper.php in App/View/Helper.
Before working with my data, what I want is just to display an example of chart to see if it is working. Which is not! I copied the example of the above-provided link (on github.com), so here is my Controller class:
<?php
App::uses ( 'AppController', 'Controller');
App::uses ('GoogleCharts', 'GoogleCharts.Lib');
class StatisticsController extends AppController{
public $helpers = array('GoogleCharts.GoogleCharts');
public $components = array (
'Paginator',
'Session'
);
public function index(){
//Setup data for chart
$chart = new GoogleCharts();
$chart->type("LineChart");
//Options array holds all options for Chart API
$chart->options(array('title' => "Recent Scores"));
$chart->columns(array(
//Each column key should correspond to a field in your data array
'event_date' => array(
//Tells the chart what type of data this is
'type' => 'string',
//The chart label for this column
'label' => 'Date'
),
'score' => array(
'type' => 'number',
'label' => 'Score',
//Optional NumberFormat pattern
'format' => '#,###'
)
));
//You can also manually add rows:
$chart->addRow(array('event_date' => '1/1/2012', 'score' => 55));
//Set the chart for your view
$this->set(compact('chart'));
}
}
In my View, I put the code
<div id="chart_div"><?php $this->GoogleChart->createJsChart($chart);?></div>
(without "s" to "GoogleChart" (not like on the download page, where is it written "GoogleCharts"), which took me 3 hours to notice)
My charts should be displayed on the page, but I got the following error:
Warning (512): Method GoogleChartHelper::createJsChart does not exist
[CORE\Cake\View\Helper.php, line 192]
(and if I put the "s" in the View, my page displays like without any error but without any chart...)
Am I missing something?
N.B. : I didn't copy the first method given on the github page, because with it a new worst error appears:
Error: Call to a member function find() on null
That method is:
//Get data from model
//Get the last 10 rounds for score graph
$rounds = $this->Round->find(
'all',
array(
'conditions' => array(
'Round.user_id' => $this->Auth->user('id')
),
'order' => array('Round.event_date' => 'ASC'),
'limit' => 10,
'fields' => array(
'Round.score',
'Round.event_date'
)
)
);
Please help me, I just want to display some random data in a chart and it should not be complicated (but with cakePHP, everything seems complex)...
The problem is that one step was missing:
you have to write
<?php echo $this->fetch('script'); ?>
in View/Layouts/bootstrap.ctp and if you followed all other steps, it should work!
I have two form on a single page: login form and register form. When I submit the register form, it validates both: form fields that are in login and registeration. How can I handle it if both form have the same model (user model)
Register form
<?php echo $this->Form->create('User', array('url' => array('controller' => 'users', 'action' => 'add'))); ?>
<?php echo $this->Form->input('username', array('label' => false, 'div' => false, 'class' => 'reg_input'));?>
<?php echo $this->Form->input('email', array('label' => false, 'div' => false, 'class' => 'reg_input'));?>
<?php echo $this->Form->input('password', array('label' => false, 'div' => false, 'class' => 'reg_input'));?>
<?php echo $this->Form->input('confirm_password', array('type' => 'password', 'label' => false, 'div' => false, 'class' => 'reg_input'));?>
<?php echo $this->Form->submit(__('Submit', true), array ('class' => 'reg_button', 'div' => false));
echo $this->Form->end();?>
and Login form is below
<?php echo $this->Form->create('User', array('controller' => 'users', 'action' => 'login'))?>
<?php echo $this->Form->input('User.username',array('label'=>false,'div'=>false, 'class' => 'reg_input'));?>
<?php echo $this->Form->input('User.password',array('label'=>false,'div'=>false, 'class' => 'reg_input'));?>
<?php echo $this->Form->submit(__('Log in', true), array ('class' => 'reg_button', 'div' => false)); ?>
<?php echo $this->Form->end();?>
When I submit registration form it validates both forms, I want to validate only the registration form.
How can I handle that?
I've come up with a "solution" (I find the approach dirty, but it works) for a different question (very similar to this). That other question worked with elements and views, though. I'll post the entire solution here to see if it helps someone (though I rather someone else comes with a different approach).
So, first: change the creation names for the two forms.
//for the registration
<?php echo $this->Form->create('Registration',
array('url' => array('controller' => 'users', 'action' => 'add'))); ?>
//for the login
<?php echo $this->Form->create('Login',
array('controller' => 'users', 'action' => 'login'))?>
The forms should work, look and post to the same actions, so no harm done.
Second step: I don't have your action code, so I'm going to explain what needs to be done in general
public function login() {
if ($this->request->is('post')) {
//we need to change the request->data indexes to make everything work
if (isset($this->request->data['Login'] /*that's the name we gave to the form*/)) {
$this->request->data['User'] = $this->request->data['Login'];
unset($this->request->data['Login']); //clean everything up so all work as it is working now
$this->set('formName', 'Login'); //we need to pass a reference to the view for validation display
} //if there's no 'Login' index, we can assume the request came the normal way
//your code that should work normally
}
}
Same thing for the registration (only need to change 'Login' to 'Registration').
Now, the actions should behave normally, since it has no idea we changed the form names on the view (we made sure of that changing the indexes in the action). But, if there are validation errors, the view will check for them in
$this->validationErrors['Model_with_errors']
And that 'Model_with_errors' (in this case 'User') won't be displayed in the respective forms because we've changed the names. So we need to also tweak the view. Oh! I'm assuming these both forms are in a view called index.ctp, for example, but if they are on separate files (if you're using an element or similar) I recommend add the lines of code for all the files
//preferably in the first line of the view/element (index.ctp in this example)
if (!empty($this->validationErrors['User']) && isset($formName)) {
$this->validationErrors[$formName] = $this->validationErrors['User'];
}
With that, we copy the model validation of the User to the fake-named form, and only that one. Note that if you have a third form in that view for the same model, and you use the typical $this->form->create('User'), then the validation errors will show for that one too unless you change the form name for that third one.
Doing that should work and only validate the form with the correct name.
I find this a messy approach because it involves controller-view changes. I think everything should be done by the controller, and the view shouldn't even blink about validation issues... The problem with that is that the render function of Controller.php needs to be replaced... It can be done in the AppController, but for every updgrade of Cakephp, you'll have to be careful of copying the new render function of Controller.php to the one replacing it in AppController. The advantage of that approach, though, is that the "feature" would be available for every form without having to worry about changing the views.
Well, it's just not that maintainable anyway, so better to leave it alone if it's just for this one case... If anyone is interested on how to handle this just in the controller side, though, comment and I'll post it.
You can duplicate your model and change his name and define $useTable as the same table name.
Example :
class Registration extends AppModel {
public $useTable = 'users';
You define the action in form->create like Nunser for your login form
<?php
echo $this->Form->create('User',array(
'url' => array(
'controller' => 'Users',
'action' => 'login',
'user' => true
),
'inputDefaults' => array(
'div' => false,
'label' => false
),
'novalidate'=>true,
));
?>
and your registration form
<?php
echo $this->Form->create('Registration',array(
'url' => array(
'controller' => 'Users',
'action' => 'validation_registration',
'user' => false
),
'inputDefaults' => array(
'div' => false,
'label' => false
),
'novalidate'=>true,
));
?>
In your controller define a method for registration validation and the most important define the render
public function validation_registration(){
$this->loadModel('Registration');
if($this->request->is('post')){
if($this->Registration->save($this->request->data)){
--- code ---
}else{
--- code ---
}
}
$this->render('user_login');
}
Sorry for my english ! Have a nice day ! :D
The create method on your login form is missing the 'url' key for creating the action attribute. I tried to re-create this once I fixed this and could not. Maybe that will fix it?
I am trying to work with HABTM association between Profiles and Qualifications tables.
Model: Profile.php
App::uses('AppModel', 'Model');
class Profile extends AppModel {
public $hasAndBelongsToMany = array(
'Qualification' => array(
'className' => 'Qualification',
'joinTable' => 'profile_qualifications',
'foreignKey' => 'profile_id',
'associationForeignKey' => 'qualification_id',
'unique' => 'keepExisting'
)
);
}
Model: Qualification.php
App::uses('AppModel', 'Model');
class Qualification extends AppModel {
public $hasAndBelongsToMany = array(
'Profile' => array(
'className' => 'Profile',
'joinTable' => 'profile_qualifications',
'foreignKey' => 'qualification_id',
'associationForeignKey' => 'profile_id',
'unique' => 'keepExisting',
)
);
}
Controller: ProfilesController.php
App::uses('AppController', 'Controller');
class ProfilesController extends AppController {
public function edit() {
$this->Profile->id = $this->Auth->user('profile_id');
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->Profile->save($this->request->data)) {
$this->Session->setFlash(__('The profile has been saved'));
$this->redirect(array('action' => 'view'));
} else {
$this->Session->setFlash(__('The profile could not be saved. Please, try again.'));
}
} else {
$this->request->data = $this->Profile->read(null, $this->Auth->user('profile_id'));
}
$salutations = $this->Profile->Salutation->find('list', array('fields' => array('Salutation.id', 'Salutation.abbr_name')));
$qualifications = $this->Profile->Qualification->find('list', array('fields' => array('Qualification.id', 'Qualification.abbr_name')));
$this->set(compact('salutations', 'qualifications'));
}
}
Vew: edit.ctp
<div class="profiles form">
<?php echo $this->Form->create('Profile'); ?>
<fieldset>
<legend><?php echo __('My Profile'); ?></legend>
<?php
echo $this->Form->input('salutation_id');
echo $this->Form->input('first_name');
echo $this->Form->input('middle_name');
echo $this->Form->input('last_name');
echo $this->Form->input('qualification'); /* gives drop down not multi select */
echo $this->Form->input('bio');
echo $this->Form->input('email');
echo $this->Form->input('mobile');
echo $this->Form->input('phone');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
The edit view thus generated contains drop down to select a single value at a time for Qualifications attribute.
I want to know how can I generate a view with multi value selection box for qualifications ?
Moreover, what is the mistake in my code right now ?
First time poster, long time user.
I stumbled across this question today, and ended up using the subsequent solution which indeed does work quite nicely. However, I left myself wondering "why wouldn't CakePHP pickup on the HABTM relationship properly?" Especially considering (at least in my case) that the majority of the files had been baked in the cake console.
If we dive a little deeper into the issue, we discover that the problem is actually quite simple. A closer look at this snippet in the PostsController.php reveals how Cake builds in the HABTM relationship to the function, and uses $this->set() in order to pass it to the view (IMPORTANT: using lower-case plural versions "salutations"):
$salutations = $this->Profile->Salutation->find('list', array('fields' => array('Salutation.id', 'Salutation.abbr_name')));
$qualifications = $this->Profile->Qualification->find('list', array('fields' => array('Qualification.id', 'Qualification.abbr_name')));
$this->set(compact('salutations', 'qualifications'));
According to the Cake Cook Book, in order to take advantage of this HABTM in the front end when using the form helper is to specify the variable in singular form & title case (ie: "Salutation")
Snippet from the cook book:
Assuming that User hasAndBelongsToMany Group. In your controller, set a camelCase plural variable (group -> groups in this case, or ExtraFunkyModel -> extraFunkyModels) with the select options. In the controller action you would put the following:
$this->set('groups', $this->User->Group->find('list'));
And in the view a multiple select can be created with this simple code:
echo $this->Form->input('Group');
Should solve your issue without any necessary field tweaking.
Cheers!
Bake on.
Perhaps you need further configuration of your input:
echo $this->Form->input('Qualification',array(
'label' => 'Qualifications',
'type' => 'select',
'multiple' => true, // or 'checkbox' if you want a set of checkboxes
'options' => $qualifications,
'selected' => $html->value('Qualification.Qualification'),
));
I've used this blog post whenever I've come up against HABTM associations. It seems to me that a set of checkboxes maybe desired by default over a select input - maybe someone with greater CakePHP insight can chime in here?
Change
echo $this->Form->input('qualification');
to
echo $this->Form->input('qualification', array(
'multiple' => true
));
The CakePHP manual has more information on the form helper input options.
Short version
I have some HABTM checkboxes on a form. Validation is working correctly (at least one checkbox needs to be checked for validation to pass) but the CakePHP error message divs aren't being generated as they should be.
Long Version
I have a from which allows users to fill in their name and email address and then choose from a list of brochures (checkboxes) they'd like to receive.
The form looks like this:
<?php
echo $this->Form->create('Request',array('action' => 'index'));
echo $this->Form->input('id');
echo $this->Form->input('name');
echo $this->Form->input('email');
echo $this->Form->input('Brochure',array(
'label' => __('Information Required:',true),
'type' => 'select',
'multiple' => 'checkbox',
'options' => $list,
'selected' => $this->Html->value('Brochure.Brochure'),
));
echo $this->Form->submit('Submit');
echo $this->Form->end();
?>
In my controller, $list is set as like this:
$this->Request->Brochure->find('list',array('fields'=>array('id','name')));
After reading the 2nd answer (posted by user448164) in HABTM form validation in CakePHP on Stack Overflow, I set my Request model up like this:
<?php
class Request extends AppModel {
var $name = 'Request';
function beforeValidate() {
foreach($this->hasAndBelongsToMany as $k=>$v) {
if(isset($this->data[$k][$k]))
{
$this->data[$this->alias][$k] = $this->data[$k][$k];
}
}
}
var $validate = array(
'name' => array(
'rule' => 'notEmpty',
'message' => 'Please enter your full name'
),
'email' => array(
'rule' => 'email',
'message' => 'Please enter a valid email address'
),
'Brochure' => array(
'rule' => array('multiple', array('min' => 1)),
'message' => 'Please select 1'
),
);
?>
This actually works 99% well. If none of the checkboxes are checked, validation fails as it should do. However, the only problem is that Cake isn't setting the "error" class on the <div>, nor is it creating the <div class="error-message">Please select 1</div> as it should.
For name and email, there is no problem - the error divs are being created properly.
So, to clarify, validation is working for my HABTM checkboxes. The only problem is that the error divs aren't being generated.
I'm posting this here as this is actually a much better question than the related question you found.
I was banging my head against a wall trying to handle the same problem of getting the validation error to show up in the page. I'm using CakePHP v1.2 and I hit a similar problem although I have actually split out the HABTM into the individual tables i.e. Request->BrochuesRequest->Brochure. This is because I can't have it deleting and re-adding the joining table rows at will.
Firstly I think the accepted answer from your linked question assumes that you are doing a save / saveAll when the beforeValidate call is triggered, however I was doing it through a validates call. The difference is that you need to call the Request->set method first. It was an article by Jonathan Snook on Multiple Validation Sets pointed me to that issue.
The second issue is actually getting the error message to appear was down to the $field value you use when calling invalidate. For ages I was including the model as well as the field assuming that this was how it matched the invalidate call to the input, i.e. you have $form->input('BrochuresRequest.brochures_id') so you need $this->BrochuresRequest->invalidate('BrochuresRequest.brochures_id').
However that is wrong you just want $this->BrochuresRequest->invalidate('brochures_id').
<?php
// requests/add view
echo $form->input('BrochuresRequest.brochures_id', array('multiple' => true));
// requests_controller
function add() {
if (!empty($this->data)) {
$this->Request->create();
// critical set to have $this->data
// for beforeValidate when calling validates
$this->Request->set($this->data);
if ($this->Request->validates()) {
$this->Request->saveAll($this->data);
}
}
}
// request model
function beforeValidate() {
if (count($this->data['BrochuresRequest']['brochures_id']) < 1) {
$this->invalidate('non_existent_field'); // fake validation error on Project
// must be brochures_id and not BrochuresRequest.brochures_id
$this->BrochuresRequest->invalidate('brochures_id', 'Please select 1');
return false;
}
return true;
}
?>
A few of the other things that I picked up on the way through:
You don't need a separate $form->error in the view
I couldn't for the life of me get the 'multiple' validation rule to work in the model
The accepted answer checks for an isset but I believe that this isn't required and masked the problem of there being no $this->data being passed through.
The beforeValidate should return false if you want it to prevent any save action.
I'm using the cakephp media plugin in my project using the monolithic style attachments table, i.e. all the attachments go in the one table with foreign_key, model, group etc. saved with the file details. So my model looks like:
class ProjectProfile extends AppModel {
var $name = 'ProjectProfile';
var $useDbConfig = 'default';
var $useTable = 'project_profiles';
var $actsAs = array('Media.Transfer', 'Media.Generator');
public $belongsTo = array(
'Project' => array(
'className' => 'Project',
'foreignKey' => 'pjID'
)
);
var $hasMany = array(
'Photo' => array(
'className' => 'Media.Attachment',
'order' => 'Photo.basename, Photo.id',
'foreignKey' => 'foreign_key',
'conditions' => array('Photo.model' => 'ProjectProfile', 'Photo.group' => 'Photo'),
'dependent' => true)
);
Then a saveAll in the controller when saving my record saves the attached file.
This all works fine, however I'd really like to be able to upload multiple files at once, which the plugin does support by doing this in the form:
echo $this->Form->hidden('Photo.0.model', array('value' => 'Photo'));
echo $this->Form->input('Photo.0.file', array('type' => 'file');
echo $this->Form->hidden('Photo.1.model', array('value' => 'Photo'));
echo $this->Form->input('Photo.1.file', array('type' => 'file');
echo $this->Form->hidden('Photo.2.model', array('value' => 'Photo'));
echo $this->Form->input('Photo.2.file', array('type' => 'file');
But I think you'd agree that's a bit cumbersome to have to click browse for each individual file. The simplist method I could see to to allow multiple file uploads was to use the HTML5 multiple file section option - http://bakery.cakephp.org/articles/veganista/2012/01/31/html_5_multiple_file_upload_with_cake :
echo $this->Form->input('files.', array('type' => 'file', 'multiple'));
This allows you to shift click in the file browser to select multiple files then puts the files into an array to save... however, this field format isn't handled by the media plugin. Also, there'd be no way to add the model, group etc. fields on the save as far as I could see.
So, does anybody know how I can handle multi file uploads with the media plugin using the monolithic model? I'm open to all suggestions.
Thanks in advance.
Will this CakePHP 2.x plugin - AjaxMultiUpload - work for you? I think that does exactly what you need it to.
