I have a piece of code that is responsible for the pagination in my controllers:
var $paginate = array(
'limit' => 5,
'conditions' => array('Tanque.user_id' => 1),
'order' => array(
'Tanque.nome' => 'asc'
)
);
So, where I have 'Tanque.user_id' => 1, I would like to use the user_id instead of the number 1. I am getting the user_id from the Session $this->Session->read('Auth.User.id'), but I get an error.
How can I use the $this->Session->read outside of the functions?
You cannot use expressions in class declarations, you can only use static values. Not to mention that all the components aren't even loaded at this stage. Do this in a function, like beforeFilter:
public function beforeFilter() {
$this->paginate['conditions']['Tanque.user_id'] = $this->Auth->user('id');
parent::beforeFilter();
}

I'm just starting out with Doctrine and was rewriting some code to use Doctrine entities in some Forms.
I have an Entity Business which has some 1:n relations with addresses, employees, emails etc. the Setup is really basic and working fine.
To add new Businesses i created a BusinessForm and Fieldsets for each of my entities. Here the constructor of the form:
public function __construct($scenario='create', $entityManager = null) {
parent::__construct('business_form');
$this->scenario = $scenario;
$this->entityManager = $entityManager;
$this->setAttribute('method', 'post');
$businessFieldset = new BusinessFieldset($this->entityManager);
$businessFieldset->setUseAsBaseFieldset(true);
$this->add($businessFieldset);
$hydrator = new DoctrineHydrator($this->entityManager, new Business());
$this->setHydrator($hydrator);
$this->addElements();
$this->addInputFilter();
}
addElements just adds a Submit and CSRF input.
And here the Controller action:
public function addAction(){
$form = new BusinessForm('create', $this->entityManager);
if ($this->getRequest()->isPost()) {
$data = $this->params()->fromPost();
$form->setData($data);
if($form->isValid()) {
// save Object
return $this->redirect()->toRoute('subcontractor', ['action'=>'index']);
}
}
return new ViewModel([
'form' => $form
]);
}
The form validates and i can get the Data from the form with $form->getData(). But i cant figure out how to get a populated Object from the form using the form's hydrator. When I use setObject(new Business()) at the start of the controller i get an error while $form->isValid() is running :
Zend\Hydrator\ArraySerializable::extract expects the provided object to implement getArrayCopy()
Isnt that the wrong hydrator being called ?
If i dont setObject() but instead use $form->bind(new Business()) after the validation i get an empty Object from $form->getObject(). If i get the data and hydrate a new Object with the form's hydrator like so : $form->getHydrator()->hydrate($data['business], new Business()) i do get the populated Object i was expecting. (Business being the name of the base fieldset)
So my question is, how to i get the result of the last call from just using $form->getObject() after the validation?
[EDIT]
The Problem seems to be with the Collections of Fieldsets used as sub-fieldsets in the businessfieldset. If i validate the form without using the collections i do get the expected Business Object from $form->getData()
Here an example how i add the collection (in the business fieldset):
$this->add([
'name' => 'emails',
'type' => 'Zend\Form\Element\Collection',
'attributes' => [
'id' => 'business_emails',
],
'options' => [
'label' => 'Emails',
'count' => 1,
'should_create_template' => true,
'template_placeholder' => '__index__',
'allow_add' => true,
'target_element' => [
'type' => 'LwsSubcontractor\Form\EmailFieldset',
],
'target_class' => 'LwsSubcontractor\Entity\Email'
],
]);
and here the EmailFieldset:
public function __construct() {
parent::__construct('email');
$this->setObject(new Email());
$this->addElements();
}
protected function addElements() {
$this->add([
'name' => 'email',
'type' => 'Zend\Form\Element\Email',
'attributes' => [
'placeholder' => 'E-Mail (z.B. email#muster-email.de)',
'class' => 'form-control',
'required' => true,
'size' => 50,
],
'options' => [
'label' => 'Email',
],
]);
}
}
If using the Collections i get the Error message from above. So after adding a hydrator to each Fieldset i was fine.
Although i was under the impression that setting the hydrator for the form would result in the used fieldsets to inherit that hydrator.Or was this because of using the fieldsets as collections and not directly ?
You have to add the hydrator to all your fieldsets, personally I use DoctrineModule\Stdlib\Hydrator\DoctrineObject for doctrine entities.
I would also look at using the init() method to initialize your forms and add elements then register and retrieve your form and fieldsets through the FormElementManager, $serviceLocator->get('FormElementManager')->get(yourFieldsetorForm::class). The form can than be injected into your controller.
I hope this helps.
I have a Form having primary key on two fields (gid, bid). I need to add validation to block duplicate entries into database.
I have checked with ZF2 Solution for this . http://framework.zend.com/manual/2.2/en/modules/zend.validator.db.html#excluding-records . While this approach of handling composite keys is not look the ideal way, But still I am trying it because it look like only buil-in way. Now it require me to provide second field's value (value option in exclude), which is again a problem. As I am trying it
$inputFilter->add(array(
'name' => 'gid',
'required' => true,
'validators' => array(
array(
'name' => 'NotEmpty',
'options' => array(
'messages' => array(
'isEmpty' => 'required'
),
),
),
array (
'name' => 'Zend\Validator\Db\NoRecordExists',
'options' => array (
'table' => 'gtable',
'field' => 'gid',
'adapter' => $this->dbAdapter,
'messages' => array(
\Zend\Validator\Db\NoRecordExists::ERROR_RECORD_FOUND => 'The specified key already exists in database'
),
'exclude' => array(
'field' => 'bid',
'value' => [?],
),
)
),
)
));
How do I get this value, As Form is absolute separate Class/File than controller where I have the submitted form values. Is some better architecture solution of this problem exists Or Some hack to pass submitted field value to Form Class is only solution ?
Note : I am not in favor of Build My Validation Plugin for this task as short time is constraint for functionality.
You can do all the job in your form. To achieve that, you could define your forms as factories in your module Module.php.
Module.php
use MyNamespace\MyForm;
//NOTE THAT THE SERVICE MANAGER IS INJECTED. YOUR FORM COULD RECEIVE IT THROUGH THE CONSTRUCTOR
public function getServiceConfig()
{
return array(
'factories' => array(
'my_form' => function( $sm ) {
$form = new MyForm( $sm );
return $form;
},
),
);
}
When you want to use the form is as easy as use this code in your controller:
class MyController extends AbstractActionController
{
public function createAction() {
$form = $this->getServiceLocator()->get( 'my_form' ) );
(...)
}
}
And your MyForm.php
use Zend\Form\Form;
class MyForm extends Form
{
public $serviceManager, $request, $postData;
public function __construct( $serviceManager ) {
parent::__construct( null );
$this->serviceManager = $serviceManager;
$this->request = $serviceManager->get( 'Application')->getMvcEvent()->getRequest();
$this->postData = get_object_vars( $this->request->getPost() );
}
}
This way you can get advantage of the Service Manager within your form. And the public postData, where you'll find the bid value you're looking for to build your NoRecordExists filter.
You could add the parameters to the getInputFilter, like this :
getInputFilter($gid, $bid)
And then on the controller, when you set the filter you pass the 2 parameters, and then just check as $form->isValid(); ...
Alternative try this:
array(
'name' => 'Db\NoRecordExists',
'options' => array(
'table' => 'gtable',
'field' => 'gid',
'adapter' => $this->dbAdapter,
),
),
I'm unsure on your use case. If you were to add a database entry the primary keys for that table would not be known until you insert anyway - If you have foreign key constraints you could handle the exception from the database.
I am not in favor of Build My Validation Plugin for this task
The validator is also not designed to validate multiple fields as they are attached to a form element on a 1-1 basis. You will therefore need to create your own.
The below example has NOT been tested, so take it as an example of the approach rather than working code.
The key bit is the isValid method.
namespace MyModule\Validator\Db;
use Zend\Validator\Db\NoRecordExists;
class CompositeNoRecordExists extends NoRecordExists
{
protected $field2;
protected $field2Value;
public function __construct($options = null)
{
parent::__construct($options);
if (array_key_exists('field2', $options)) {
$this->setField2($options['field2']);
} else {
throw new \BadMethodCallException('Missing field2 option!');
}
}
protected function setField2Value(array $context)
{
if (! isset($context[$this->field2])) {
throw new \BadMethodCallException('Unable to find value for field 2');
}
$this->field2Value = $context[$this->field2];
}
public function isValid($value)
{
// The isValid() method is actually given a 2nd argument called $context
// Which is injected by the inputFilter, via the input and into the validator chain
// $context contains all of RAW form element values, keyed by thier element name.
// Unfortunately due to the ValidatorInterface you are unable to add this to the method
// signature. So you will need to be 'creative':
$args = func_get_args();
if (isset($args[1]) && is_array($args[1])) {
$this->setField2Value($args[1]);
} else {
throw new \BadMethodCallException('Missing validator context');
}
return parent::isValid($value);
}
public function getSelect()
{
$select = parent::getSelect();
$select->where->equalTo($this->field2, $this->field2Value);
return $select;
}
}
Then all you would need to do is update the validator config, adding the field2 field name.
array (
'name' => 'MyModule\Validator\Db\CompositeNoRecordExists',
'options' => array (
'table' => 'gtable',
'field' => 'gid',
'field2' => 'bid',
'adapter' => $this->dbAdapter,
'messages' => array(
\Zend\Validator\Db\NoRecordExists::ERROR_RECORD_FOUND => 'The specified key already exists in database'
),
)
),
I am currently working on a custom module add-on and I wanted to be able to use sorting and filtering on the a table in my control panel admin. I am using the EE table class and form helper. I'm trying to follow the documentation here for setting it up, but when I call try to call the '_datasource' method in my class I get this error
Fatal error: Call to undefined method Content_publish::_datasource() in /home/public_html/system/expressionengine/libraries/EE_Table.php on line 162
I have a feeling it's a scoping issue, but in the table class '$this->EE->table->datasource()' method you are supposed to just pass a string value with the name of your datasource function which is what I'm doing.
I don't seem to be the only one with this issue. There are more details and code examples on this EE Discussion forum thread
The documentation is not really clear. I also tried looking at EE's own comments module to see if i could figure it out, but no luck. Anyone have experience with this?
Here is the method I'm calling:
$data = $this->EE->table->datasource('_datasource');
And this is my function in my class:
function _datasource()
{
// ....
// $query comes from DB result set code above.
// I have omitted it here for brevity
$datarows = array();
foreach ($query->result_array() as $key => $row)
{
$datarows[] = array(
'entry_id' => $row['entry_id'],
'date' => date('Y-m-d',$row['entry_date']),
'author' => $row['screen_name'],
'payment' => $payment_amount,
'status' => $status,
'title' => $edit_href.$row['title']."</a>"
);
}
return $datarows;
}
Your datasource callback function must be on your Module_mcp class (looking at your forum thread you are trying to use it on a plugin which would explain the error).
If you want to put the datasource method on a different class, then just add this line right before you call datasource() to trick the table library into using the correct class:
// ensure table callbacks use this class rather than our MCP file
$this->EE->_mcp_reference =& $this;
$data = $this->EE->table->datasource('_datasource');
The table and form_validation libraries are the only two which use the special _mcp_reference variable, so I can't see any side effects to changing it, and have successfully done this in at least two modules.
On a side note, if you want a good example of how to use the built in tablesorter, take a look at system/expressionengine/controllers/cp/members.php. The documentation is pretty bad, but the source code always tells the truth :)
I've been having issues too and have a mixed solution of generate() and datasource working. Here it is here:
In my mcp file:
public function index()
{
$this->EE->cp->set_variable('cp_page_title', lang('my_module_name'));
$data = $this->EE->table->datasource('_datasource');
return $this->EE->load->view('index', $data, TRUE);
}
public function _datasource()
{
$headers = array(
'name' => array('header' => 'Name'),
'color' => array('header' => 'Color'),
'size' => array('header' => 'Size')
);
$rows = array(
array('name' => 'Fred', 'color' => 'Blue', 'size' => 'Small'),
array('name' => 'Mary', 'color' => 'Red', 'size' => 'Large'),
array('name' => 'John', 'color' => 'Green', 'size' => 'Medium'),
);
return array(
'rows' => $rows,
'headers' => $headers
);
}
In my index view file:
$this->table->set_columns($headers);
$this->table->set_data($rows);
echo $this->table->generate();
Seems to be working at the moment and I've not tried pagination yet, but sorting works.
In my Vacation model Vac I have this function
public function getVacCount(){
this function returns how many days there are in one vacation.
and I want to add a custom column to the cgridview like this:
<?php
$this->widget('zii.widgets.grid.CGridView', array(
...
array(
'name' => 'count',
'value' => '$data->getVacPeriod()'
),
...
),
));
?>
it works fine.
but I don't know how can I sort upon this custom attribute.
I tried to use CSort but it does not work. any idea?
To use CSort for sorting, you'll need to convert your vacation function into a SQL query and then stash the results in a public variable in your model.
CSort only works with SQL statements/functions, as underneath it's using ORDER BY to do all the sorting.
More info (and demo code) available here
Here's a sample of how I'm doing it on a site of mine:
$criteria->select = array(
"*",
new CDbExpression("IF(survey.RequestDate, survey.RequestDate, SurveyCompleteDate) AS SurveyDate")
);
This then allows me to do this type of filter:
return new CActiveDataProvider($this, array(
'criteria' => $criteria,
'sort'=>array(
'attributes'=>array(
'SurveyDate' => array(
'asc' => 'SurveyDate',
'desc' => 'SurveyDate DESC',
),
'*',
),
),
);
Note: you'll also need a public variable defined in your model to hold the results of the CDbExpression that you're doing. Mine is called SurveyDate.
I want to use CakePHP's core validation for lists in my model:
var $validate = array(
'selectBox' => array(
'allowedChoice' => array(
'rule' => array('inList', $listToCheck),
'message' => 'Enter something in listToCheck.'
)
)
);
However, the $listToCheck array is the same array that's used in the view, to populate a selectbox. Where do I put this function?
public function getList() {
return array('hi'=>'Hello','bi'=>'Goodbye','si'=>'Salutations');
}
Already in my controller, in one of the actions I'm setting it for the view, like:
public function actionForForm() {
$options = $this->getList();
$this->set('options', $options);
}
So, I don't want to have to copy the getList() function...where can I put it so the Model can call it to populate its $listToCheck array?
Thanks for your help.
Considering that it's data, you should store the list of valid choices in the model.
class MyModel extends AppModel {
var $fieldAbcChoices = array('a' => 'The A', 'b' => 'The B', 'c' => 'The C');
}
You can get that variable in the Controller simply like this:
$this->set('fieldAbcs', $this->MyModel->fieldAbcChoices);
Unfortunately you can't simply use that variable in the rule declaration for the inList rule, since rules are declared as instance variables and those can only be initialized statically (no variables allowed). The best way around that is to set the variable in the Constructor:
var $validate = array(
'fieldAbc' => array(
'allowedChoice' => array(
'rule' => array('inList', array()),
'message' => 'Enter something in listToCheck.'
)
)
);
function __construct($id = false, $table = null, $ds = null) {
parent::__construct($id, $table, $ds);
$this->validate['fieldAbc']['allowedChoice']['rule'][1] = array_keys($this->fieldAbcChoices);
}
If you're not comfortable overriding the Constructor, you could also do this in a beforeValidate() callback.
Also note that you shouldn't name your field 'selectBox'. :)
