Execute Query with Where Condition For ResultSet Zend Framework 2? - php

I have one tabel 'cms' which include cms page with 3 separate parent category(type) . when i call fetchAll() function which fetch all data but i want to only fetch data which parent category(type)='1' means i want to pass where condition and orderby condition in fetchAll() function.
My Cms.php page is:
<?php
namespace Front\Model;
use Zend\Db\TableGateway\AbstractTableGateway;
class Cms extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'cms';
$this->adapter = $adapter;
}
public function fetchAll($id) {
return $this->select();
}
public function getCmsContent($id){
$id = (int) $id;
$rowset = $this->select(array('id'=>$id));
if (!$row = $rowset->current()){
throw new \Exception ('Row not found');
}
return $row;
}
}
My Controller is :FrontController.php is:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Front\Model\Cms;
use Front\Model\Setting;
use Front\Model\Slider;
class FrontController extends AbstractActionController
{
public function indexAction()
{
return array('cms_data'=>$this->getCms()->fetchAll('1'));
}
public function getCms(){
return $this->getServiceLocator()->get('Front\Model\Cms');
}
}
My Model is:
namespace Front;
class Module
{
public function getAutoloaderConfig()
{
return array('Zend\Loader\StandardAutoloader' =>
array('namespaces' =>
array(__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,),
),
);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
// Add this method:
public function getServiceConfig()
{
return array(
'factories' => array(
'Front\Model\Cms' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Front\Model\Cms($dbAdapter);
return $table;
},
),
);
}
}
?>
My View:index.php Page is:
<?php print_R($cms_data); ?>

Your question is not clear. Are you asking how to add Where clause to your query? If so, then this is it:
use Zend\Db\Sql\Predicate\Operator;
public function fetchAll($id) {
return $this->select()
->where(new Operator('type', Operator::OPERATOR_EQUAL_TO, $id);
}

different fileds for a model in yii2 rest api

I created custom actions for rest api in yii2
my codes are:
namespace app\controllers;
use yii\rest\ActiveController;
use yii\web\Response;
use Yii;
class RsController extends ActiveController{
public $modelClass='app\models\Mymodel';
/*some another actions*/
public function actionOne($id){
return \app\models\Anothermodel::findAll(['my_id'=>$id]);
}
public function actionTwo($id){
return \app\models\Anothermodel::findAll(['my_name'=>'xxxx']);
}
}
I know we can override fields function in model to get special fields but
now I wanted to get different fields for actionOne and actionTwo (of a model)
How can I override fields function in Anothermodel for this purpose?
I found my answer from here
I create a component like this
<?php
namespace app\components;
class Serializer extends \yii\rest\Serializer {
public $defaultFields;
public $defaultExpand;
public function init() {
parent::init();
$this->defaultFields = !is_null($this->defaultFields) ? implode(",", $this->defaultFields) : $this->defaultFields;
$this->defaultExpand = !is_null($this->defaultExpand) ? implode(",", $this->defaultExpand) : $this->defaultExpand;
}
protected function getRequestedFields() {
$fields = is_null($this->request->get($this->fieldsParam)) ? $this->defaultFields : $this->request->get($this->fieldsParam);
$expand = is_null($this->request->get($this->expandParam)) ? $this->defaultExpand : $this->request->get($this->expandParam);
return [
preg_split('/\s*,\s*/', $fields, -1, PREG_SPLIT_NO_EMPTY),
preg_split('/\s*,\s*/', $expand, -1, PREG_SPLIT_NO_EMPTY),
];
}
}
and then in my controllers action set my fields
like this.
public function actionOne($id){
$this->serializer['defaultFields'] = ["field1",
"field2"];
return new \yii\data\ActiveDataProvider([
'query' => \app\models\Anothermodel::find()->where(['my_id'=>$id]),
]);
}
public function actionTwo($id){
$this->serializer['defaultFields'] = ["field1",
"field2","field3"];
return new \yii\data\ActiveDataProvider([
'query' => \app\models\Anothermodel::find()->where(['my_id'=>$id]),
]);
}
I suggest to use events
public function actionPublic()
{
\yii\base\Event::on(Thing::class, Thing::EVENT_AFTER_FIND, function ($event) {
$event->sender->scenario = Thing::SCENARIO_SEARCH_PUBLIC;
});
return new ActiveDataProvider([
'query' => Thing::find(),
]);
}
public function actionPrivate()
{
\yii\base\Event::on(Thing::class, Thing::EVENT_AFTER_FIND, function ($event) {
$event->sender->scenario = Thing::SCENARIO_SEARCH_PRIVATE;
});
return new ActiveDataProvider([
'query' => Thing::find(),
]);
}
and inside of ActiveRecord (Thing in my case) check the scenario in fields() method
public function fields()
{
$fields = parent::fields();
if ($this->scenario === self::SCENARIO_SEARCH_PUBLIC) {
unset($fields['field1'], $fields['field2'], $fields['field3'], $fields['field4']);
}
return $fields;
}

How to get value from table and display it at view?

I'm new to PHP framework (using Yii framework). How to get a value in MySQL then display it at a view? I'm confused in defining a model, controller, and how to use it.
Model:
public $name;
public $info;
$product = product::find()->orderBy('name')->all();
public function tablename()
{
return 'productdata';
}
Controller:
public function actionView($id)
{
$this->render('view',array(
'model'=>$this->loadModel($id),
));
}
public function LoadModel($id){
$model=productdata::model()->find($id);
return $model;
}
Have you tried any tutorials?
[models/MyModel.php]
class MyModel extends CActiveRecord {
public function rules() {
return ['id, name, value', 'safe'];
}
}
[controllers/MyController.php]
class MyController extends CController {
public function actionView($id) {
$model = MyModel::model()->findByPk($id);
$attributes = Yii::app()->request->getParam('MyModel');
if ($attributes) {
if ($model->save()) {
$this->redirect('myController/admin');
} else {
throw new CHttpException(500, 'Model not saved. Use echo CActiveForm::validat($model);');
}
}
$this->render('view', ['model' => $model]);
}
}
[views/MyController/view.php]
<?php echo $model->name; ?>

Order By Condition For ResultSet Zend Framework 2?

I have one tabel 'cms' when i call fetchAll() function which fetch all data fetch data with order by id desc means i want to pass orderby condition with fetchAll() function.
My Cms.php page is:
<?php
namespace Front\Model;
use Zend\Db\TableGateway\AbstractTableGateway;
class Cms extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'cms';
$this->adapter = $adapter;
}
public function fetchAll($id) {
return $this->select();
}
public function getCmsContent($id){
$id = (int) $id;
$rowset = $this->select(array('id'=>$id));
if (!$row = $rowset->current()){
throw new \Exception ('Row not found');
}
return $row;
}
}
My Controller is :FrontController.php is:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Front\Model\Cms;
use Front\Model\Setting;
use Front\Model\Slider;
class FrontController extends AbstractActionController
{
public function indexAction()
{
return array('cms_data'=>$this->getCms()->fetchAll('1'));
}
public function getCms(){
return $this->getServiceLocator()->get('Front\Model\Cms');
}
}
My Model is:
namespace Front;
class Module
{
public function getAutoloaderConfig()
{
return array('Zend\Loader\StandardAutoloader' =>
array('namespaces' =>
array(__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,),
),
);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
// Add this method:
public function getServiceConfig()
{
return array(
'factories' => array(
'Front\Model\Cms' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Front\Model\Cms($dbAdapter);
return $table;
},
),
);
}
}
?>
My View:index.php Page is:
<?php print_R($cms_data); ?>
An excerpt from the manual:
$select = new Select;
$select->order('id DESC'); // produces 'id' DESC
$select = new Select;
$select->order('id DESC')
->order('name ASC, age DESC'); // produces 'id' DESC, 'name' ASC, 'age' DESC
$select = new Select;
$select->order(array('name ASC', 'age DESC')); // produces 'name' ASC, 'age' DESC
The same method order applies to table gateway.

How to get access to the model in the view - Symfony 2

I have the following model:
class Person
{
public $name;
function __Construct( $name )
{
$this->name = $name;
}
}
I have the following controller:
class NavigationController extends Controller
{
public function indexAction()
{
$people = array(
new Person("James"),
new Person("Bob")
);
return $this->render('FrameworkBundle:Navigation:index.html.php', $people);
}
}
How do I get access to the model array in the view. Is there a way to access the model directly or do I have to assign a property like so:?
class NavigationController extends Controller
{
public function indexAction()
{
$people = array(
new Person("James"),
new Person("Bob")
);
return $this->render('FrameworkBundle:Navigation:index.html.php', array( "model" => $people ) );
}
}
View:
<?php
foreach( $model as $person )
{
echo $person->title;
}
?>
The problem with the above will be that it can be changed by a user to
return $this->render( 'FrameworkBundle:Navigation:index.html.php', array( "marybloomingpoppin" => $people ) );
With the example view you used, you already had the correct implementation:
class NavigationController extends Controller
{
public function indexAction()
{
$people = array(
new Person("James"),
new Person("Bob")
);
return $this->render('FrameworkBundle:Navigation:index.html.php', array( "model" => $people ) );
}
}
You mentioned the concern that somebody could change the assignment in the controller, but this is something you always have if somebody changes the name of a variable only in one place and not in all. So I don't think this is an issue.

Problem loading models with modules in Zend Framework

I have a folder structure like this and I'm trying to load the News model inside my controller:
<?php
/**
* Login
*/
class Admin_NewsController extends Zend_Controller_Action {
public function preDispatch() {
$layout = Zend_Layout::getMvcInstance();
$layout->setLayout('admin');
}
public function init() {
$this->db = new Application_Admin_Model_DbTable_News();
}
public function indexAction() {
}
public function addAction() {
//$this->getHelper('viewRenderer')->setNoRender();
// Calls the Request object
$request = $this->getRequest();
if ($request->isPost()) {
// Retrieves form data
$data = array(
"new_title" => $request->getParam('txtTitle'),
"new_text" => htmlentities($request->getParam('txtNews')),
"new_image" => $request->getParam('upName'),
"new_published" => 1
);
// Inserts in the database
if ($this->db->addNews($data)) {
$this->view->output = 1;
} else {
$this->view->output = 0;
}
} else {
$this->view->output = 0;
}
$this->_helper->layout->disableLayout();
}
}
And my model:
<?php
class Application_Admin_Model_DbTable_News extends Zend_Db_Table_Abstract
{
protected $_name = 'news';
public function addNews($data) {
$this->insert($data);
}
}
Althoug I'm getting this error:
Since your News class belongs to the module, its name should be Admin_Model_DbTable_News, without Application_ prefix.
