Exception from controller to view

in my controller, I have this code (I'm getting last order through a form):

    ...
      

foreach($array as $item){
try {
$product = $this->_productRepository->getById($item['product_id']);
$product_id = $product->getId();

} catch (NoSuchEntityException $e) {
$this->messageManager->addErrorMessage('Un ou plusieurs produits n\'existe(nt) plus');
continue;
}

if(isset($product)){
$param = array(
'product' => $item['product_id'],
'qty' => $item['qty']
);
}
}


I want to display a simple message on my view. The exception is way to big, I want only to show 'product doesn't exist'. How can I do that ? I saw that I can achieve this with "message manager", but how can I get the exception from the controller to my view ?

 

On the front, I try

$e->getMessage()

but $e is not define

In fact, this is working. I didn't need to show $e, it's automatically ^^,

Re: Exception from controller to view

You can use throw for send message to front,

foreach($array as $item){
    try {
        $product = $this->_productRepository->getById($item['product_id']);
        $product_id = $product->getId();

    } catch (NoSuchEntityException $e) {
        throw new \Magento\Framework\Exception\LocalizedException(__('Un ou plusieurs produits n\'existe(nt) plus'));
        continue;
    }

    if(isset($product)){
        $param = array(
            'product' => $item['product_id'],
            'qty' => $item['qty']
        );
    }
}
