url parameter becomes null after clicking button - php

Question

Here is my route:
'router' => array(
'routes' => array(
'upload' => array(
'type' => 'segment',
'options' => array(
'route' => '/products/upload[/:products]',
'defaults' => array(
'controller' => 'Products\Controller\Upload',
'action' => 'index'
),
),
'may_terminate' => true,
'child_routes' => array(
'uploadsuccessful' => array(
'type' => 'literal',
'options' => array(
'route' => '/uploadsuccessful',
'defaults' => array(
'controller' => 'Products\Controller\Upload',
'action' => 'successful'
),
),
),
),
),
),
);
I am trying to call this route several times from different view scripts giving different [/:products] parameter.
Upload Shoes Product Image
Upload Trainers Product Image
Upload Hat Product Image
Here is my Controller code.
<?php
namespace Products\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Products\Form\UploadForm;
class UploadController extends AbstractActionController
{
protected $_dir = null;
public function indexAction()
{
$products = $this->params()->fromRoute('products');
$config = $this->getServiceLocator()->get('Config');
$fileManagerDir =$config['file_manager']['dir'];
$this->_dir = realpath($fileManagerDir) .
DIRECTORY_SEPARATOR .
$products;
if (!is_dir($this->_dir)) {
//read, write, execute
mkdir($this->_dir, 0777);
}
$form = new UploadForm($this->_dir, 'upload-form');
$request = $this->getRequest();
if ($request->isPost()) {
$post = array_merge_recursive(
$request->getPost()->toArray(),
$request->getFiles()->toArray()
);
$form->setData($post);
if ($form->isValid()) {
$data = $form->getData();
$this->setFileNames($data);
return $this->redirect()->toRoute('upload/uploadsuccessful', array('products' =>$products));
}
}
return new ViewModel(array('form' => $form));
}
public function successfulAction()
{
$file = array();
$flashMessenger = $this->flashMessenger();
if ($flashMessenger->hasMessages()) {
foreach($flashMessenger->getMessages() as $key => $value) {
$file = $value;
}
}
return new ViewModel(array('file' => $file));
}
protected function setFileNames($data)
{
unset($data['submit']);
foreach ($data['image-file'] as $key => $file) {
rename($file['tmp_name'], $this->_dir . DIRECTORY_SEPARATOR . $file['name']);
}
}
}
I think the idea is clear: for each [/:products] parameter I tried to make separate folder with given name in $fileManagerDir.
But, there is a problem. When I click on button upload ($request->isPost() == true) parameter $products becomes null and uploaded files don't go to appropriate folders. Also I am not able to redirect to successful action - the error appears "missing parameter" because $products is null.

In your view script the upload buttons are href links. This will result in a GET REQUEST being sent to the controller and not a POST and no FILES will be present either. Unless that is, you are intercepting the click event with external JS which you haven't mentioned here. The route url's should be in the form action attribute. The submit buttons should be buttons not links (unless you are using JS not mentioned here). Make sure the form method is set to POST.
Something like:
<form action="<?php echo $this->url('upload', array('products' =>'shoes')); ?>" method="post" enctype="multipart/form-data">
You'll need to deal with the dynamic action using JS or redesign your routing.
