In this article, we will see how to get data in view layer ( presentation layer ) from action controller using ViewModel class.
This article belongs the series “Web application development with Zend Framework 2“.
For this, we will continue with the application “Zf2StudentApp” developed in the article titled “Zend Framework2 – Creating module, controller, actions, views and routing“.
1. Setup the application “Zf2StudentApp”
Please follow the steps explained in the article titled “Zend Framework2 – Creating module, controller, actions, views and routing” and ensure that you are getting the screen shown in the Figure 1, below :
- Figure 1 : Screenshot of the application with Student Module
2. Update the indexAction of the StudentController in the file Zf2StudentApp/module/Student/src/Student/Controller/StudentController.php
namespace Student\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
class StudentController extends AbstractActionController{
public function indexAction(){
return new ViewModel(array(
'students'=>array(
array(
"name"=>"A Mitra",
"department"=>"Physics",
"marks"=>77
),
array(
"name"=>"Mukherjee P S",
"department"=>"Physics",
"marks"=>89
),
array(
"name"=>"Rani Mathew",
"department"=>"Computer Science",
"marks"=>91
),
array(
"name"=>"Rakesh Krishna",
"department"=>"Computer Science",
"marks"=>72
),
array(
"name"=>"Faisal Ahmed",
"department"=>"ComputerScience",
"marks"=>93
)
)
));
}
}
3. Update the index.phtml file
<h1>
Students List
</h1>
<table border="1">
<thead>
<tr>
<th>No</th>
<th>Name</th>
<th>Department</th>
<th>Marks</th>
<tr>
</thead>
<?php
$i=1;
foreach($students as $student){
echo "<tr>";
echo "<td>" . $i++ . "</td>";
echo "<td>" . $student["name"] . "</td>";
echo "<td>" . $student["department"] . "</td>";
echo "<td>" . $student["marks"] . "</td>";
echo "</tr>";
}
?>
</table>
