I'm updating cakephp2 to cakephp3.
For model side, I can not get paginate parameters using func_get_arg() function in Model.
How can I get it?
I want to keep using func_get_arg() because other Model classes have also same logic.
class TopController extends AppController {
public function showTop() {
$query = array(
'limit' => 5,
'extra' => array(
'data' => 'test',
),
);
$topRawTable = TableRegistry::get('TopRawSql');
$pages = $this->Paginator->paginate($topRawTable->paginate($query)); //Error occur
}
}
class TopRawSqlTable extends Table {
public $useTable = false;
function paginate()
{
$extra = func_get_arg(6); // null
$limit = func_get_arg(3); // null
$page = func_get_arg(4); // null
// Execute custom query
}
}
I knew that CakePHP2 supports override paginate() and paginateCount() functions. But CakePHP3 DOESN'T support override paginate() and paginateCount(). That's why I couldn't get parameters by func_get_arg().
So, I switched to use CakePHP2 paginator feature.

i'm creating a application in which i need to populate data in select element from a db table.
i need to populate user roles from db
my form code is
$this->pass2->addValidator('Identical', false, array('token' => 'pass1'));
$this->addElement('select', 'userrole', array(
'class' => 'form-control',
'required' => true,
'multiOptions' =>
));
what should i do with multi options ?,
is there any way to load data from db in element using controller ,please helpme
thanks
What I have done in the past is to pass the db-adapter (or a model that knows how to do the required db query) to the form as a constructor parameter.
Something like this:
class Application_Form_MyForm extends Zend_Form
{
protected $db;
public function __construct($db)
{
$this->db = $db;
// Don't forget to call the parent __construct. Ultimately
// it is the parent __construct() that calls your init()
// method that adds your elements
parent::__construct();
}
public function init()
{
// Create your form elements
// $this->addElement('text', 'my_text_field'); // etc
// Now your select field...
$this->addElement('select', 'my_select', array(
'multiOptions' => $this->buildMultiOptions(),
'validators' => array(
// blah, blah
),
);
}
protected function buildMultiOptions()
{
$select = $this->db->select()
->from('my_table', array(
'my_value_column',
'my_display_column'
))
->order(array(
'my_display_column ASC',
));
$results = $this->db->query($select)->fetchAll();
$return = array();
foreach ($results as $row) {
$return[$row['my_value_column']] = $row['my_display_column'];
}
return $return;
}
}
Then in the controller action, when you instantiate your form, you grab the db-adapter and pass it in as a constructor parameter:
$db = $this->getInvokeArg('bootstrap')->getResource('db');
$form = new Application_Form_MyForm($db);
// Then process your form as usual
on case with is necessary populate options outside form class.
$form->getElement( 'ele_name' )
->setConfig(new Zend_Config( array(
'multiOptions' => array('option1','option2') )
)));
I'm having problem in editing associated (BelongsTo) field...
Class ModelA extends AppModel {
public $belongsTo = array ('ModelB');
public $actsAs = array('Containable');
public function getModelA($id){
$modelA = $this->find('all', array('contain' => array('ModelB'),'conditions' => array('ModelA.id' => $id)));
if(count($modelA)>0){
$modelA = $modelA[0];
}
return $modelA;
}
}
class ModelAsController extends AppController {
public function edit($id = null) {
$modelA = $this->ModelA->getModelA($id);
$this->set('modelA', $modelA);
}
}
Data in the $modelA is in the format:
array(
'ModelA' => array(
...
),
'ModelB' => array(
...
)
)
So far, everything is fine...
But, I'm stuck with the edit.ctp. I need input for editing of the field1 from the ModelB, but I'm getting empty input box. Line of the code goes like this:
echo $this->Form->input('ModelB.field1');
When I try to debug:
Debugger::log($modelA['ModelB']['field1']);
then I have correct value.
What would be the way to have input box filled with field1 of the ModelB?
for a FormHelper to pickup the model data you have to set
$this->request->data = $modelA;
in the Controller, otherwise the helper has no idea where you've hidden the data :)
(tip: usually you can debug the helper code in such cases)
I have added translate behaviour to a model, the model comes here
App::uses('AppModel', 'Model');
class Category extends AppModel
{
public $hasMany = "Product";
public $validate = array(
'name' => array(
'rule' => 'notEmpty'
)
);
public $actsAs = array(
'Translate' => array(
'name','folder','show'
)
);
public $name = "Category";
public $translateModel = 'KeyTranslate';
}
And heres the controller for updating the model
public function admin_edit_translate($id,$locale)
{
$this->Category->locale = $locale;
$category = $this->Category->findById($id);
if ($this->request->is('post') || $this->request->is('put')) {
$this->Category->id = $id;
if ($this->Category->save($this->request->data)) {
$this->Session->setFlash('Category translate has been updated');
//$this->redirect(array('action' => 'edit',$id));
} else {
$this->Session->setFlash('Unable to update category');
}
}
if (!$this->request->data) {
$this->request->data = $category;
}
}
My Problem is that i have a name field in the categories database and when i update or create a new translation it gets updated with the translated value. How do i avoid that
You must use Model::locale value to set code language for save in database
This happens because the TranslateBehavior uses callbacks like beforeSave and afterSave to save translated content, so it needs to let the model's save operation continue and thus will contain the last translated content.
You could get around this by tricking the TranslateBehavior into thinking the model is saving something by calling the beforeSave and afterSave like this:
$Model = $this->Category;
$Model->create($this->request->data);
$Model->locale = $locale;
$beforeSave = $Model->Behaviors->Translate->beforeSave($Model, array(
array(
'callbacks' => true
)
));
if($beforeSave) {
$Model->id = $id;
$Model->Behaviors->Translate->afterSave($Model, true);
}
This way the translation will be saved and the main table will be left untouched. Might not be the best way to save translations though. Why do you need to leave the main table untouched?
Callback Behavior::beforeSave is before Model::beforeSave...
but, the simplest way to modify data in Model::beforeSave before Behavior::beforeSave before realy saving is:
$this->Behaviors->Behavior_Name->runtime[Model_Name]['beforeSave'][Field_Name] = '...';
i have created one function in cakephp appcontrollet.php file. that retrive me the detail on that record from that id
the function is mentioned below
function getDetail($id = null) // to check that user is valid or not
{
$data = $this->ModelName->find('first',array('conditions'=>array('ModelName.is_active'=>'Y','ModelName.is_deleted'=>'N','ModelName.primaryKey'=>$id)));
if($data !=array())
{
// return true;
return $data;
} else {
$data = array();
return $data;
//return false;
}
}
Now i want to call this function from any controlller to get detail of the record like i will call this function fron Userscontroller,adminscontroller, marketscontroller etc. and it will return me the related data
my issue is that how should appcontroller know that request is come from which controller and which model to user ?
can anyone help me to solve this
thanks in advance
Put this function to AppModel and call it from each controller with the related model. The function then looks like:
class AppModel extends Model
{
public function getDetail($id = null) {
$data = $this->find('all', array(
'conditions' => array($this->name.'.id' => $id)
));
// ...
Depending on your call from the model it will automatically use the right model. Such a call may look like this:
class UsersController extends AppController
{
public $uses = array('User', 'Market');
public function index()
{
// Fetch data from markets database
$this->Market->getDetail($id);
// Fetch data from users database
$this->User->getDetail($id);
// ...
In this case, the model Market will be used to fetch the details from the database.
I'm building a form which contains a category field. I need a choice list to do that, but I don't find out how to fill this choice list with the several categories stored in the database.
public function buildForm(FormBuilder $builder, array $options) {
$builder->add('item', 'text', array('label' => 'Item'));
$builder->add('category', 'choice', array(
'choices' => ???,
'label' => 'Category'
));
}
How can I get the categories from the database?
(I can't seem to access $this->getDoctrine() inside this class.)
Use type entity instead of choice
$builder
->add('entity_property', 'entity', array(
'class' => 'Namespace\\To\\Entity',
'query_builder' => function(EntityRepository $repository) {
return $repository->createQueryBuilder('q')
->where('q.a_field = yourvalue');
}
));
Edit:
Two ways for using custom parameters in your query. In both situations, the parameters are injected from outside, so your FormType don't need any references to the session or request objects or whatever.
1- Pass required parameters to your constructor
class TaskType extends AbstractType
{
private $custom_value;
public function __construct($custom_value) {
$this->custom_value = $custom_value;
}
// ...
}
in your buildForm() you must copy the value to local variable and make it available for the query_builder callback:
public function buildForm(/*...*/) {
$my_custom_value = $this->custom_value;
// ...
'query_builder' => function(EntityRepository $repository) use ($my_custom_value) {
return $repository->createQueryBuilder('q')
->where('q.a_field = :my_custom_value')
->setParameter('my_custom_value', $my_custom_value);
}
// ...
}
2- use the $options parameter of the buildForm method.
First you have to define a default value by overriding getDefaultOptions:
public function getDefaultOptions(array $options)
{
return array(
'my_custom_value' => 'defaultvalue'
);
}
Then you can pass it from your controller in the third argument of the createForm method.
$this->createForm(new YourFormType(), $entity, array('my_custom_value' => 'custom_value'));
Now the value should be available through the $options parameter of youru buildForm method. Pass it to the callback as described above.
In Symfony 2.1
You now have to use the OptionsResolverInterface within the setDefaultOptions method. Here is the code you would have to use if you wanted to retrieve the options (using the same example as the accepted answer)
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
public function buildForm(FormBuilderInterface $builder, array $options){
parent::buildForm($builder, $options);
$my_custom_value = $options[custom_value];
// ...
'query_builder' => function(EntityRepository $repository) use ($my_custom_value) {
return $repository->createQueryBuilder('q')
->where('q.a_field = :my_custom_value')
->setParameter('my_custom_value', $my_custom_value);
}
// ...
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'my_custom_value' => 'defaultvalue'
));
}
You still pass the options in the same way:
$this->createForm(new YourFormType(), $entity, array('my_custom_value' => 'custom_value'));
