Modify Twig template variable using AJAX

Modify Twig template variable using AJAX

I'm attempting to dynamically reload a section of my HTML with new data fetched through AJAX.

Within the code, there is a loop that iterates over clients:

{% for client in clients %}

After making an AJAX request and receiving updated client information,

        $search = $request->request->get('data');

        $clients=$this->getDoctrine()->getRepository(
        Client::class)->findBy(array('name'=>$search));

        $response = new JsonResponse();
        $response->setStatusCode(200);
        return $response->setData(['search' => $clients ]);

I am trying to replace the existing client data with this newly obtained set.

Is there a method to achieve this, or should I explore alternative approaches?

Appreciate your assistance!

To update the clients value using AJAX, you need to follow a specific approach because the template has already been rendered. One solution is to create a separate twig template as shown below:

{# loop.html.twig #}
{% for client in clients %}
.. your code
{% endfor %}

Next, include this template in your main template like so:

<div id="client-loop-container">
    {% include 'loop.html.twig' %}
</div>

In your AJAX controller, fetch the clients based on search criteria and render the template:

$clients = $this->getDoctrine()->getRepository(
        Client::class)->findBy(array('name'=>$search));

$template = $this->render('yourTemplate.html.twig')->getContent();
$response = new JsonResponse();
$response->setStatusCode(200);
return $response->setData(['template' => $template ]);

Lastly, handle the AJAX response in your JavaScript function:

$.ajax({
    type: "POST",
    success: function(response) {
        response = JSON.parse(response);
        $("div#client-loop-container").html(response.template);    
    }
});

Unfortunately, the limitation stems from Twig being rendered on the server side. To achieve this task, consider modifying the HTML output produced by {% for client in clients%} with the help of JavaScript.

When working in your controller

$clients=$this->getDoctrine()->getRepository(
        Client::class)->findBy(array('name'=>$search));

return $this->render('yourTemplate.html.twig')->getContent();

In the Twig file

$.ajax({
    type: "POST",
    success: function(data) {

        $("div#client-loop-container").html(data);    
    }
});
