Symfony form, saving filtration through pagination - forms

Question

I use filtration form and pagination on same page to display great number of objects.
If i use POST form, after going through pagination filtration resets. If i use GET form filtration works, but URL is not clear and even have token.
Something like this:
?form[date_from][year]=&form[date_from][month]=&form[date_from][day]=&form[date_to][year]=&form[date_to][month]=&form[date_to][day]=&form[email]=email&form[submit]=&form[_token]=Nk0prilVJiROZaQQKvCt-hRfnKdh0IdDOWOIer
Is any way to make url more clear, hide token and unused parameters?

Answer 1

Well, i find no solution and write service for handling form filtration data in sessions.

Answer 2

Save filtration: use an array in controller:
$filter_array=[];
if ($search_form->isSubmitted() && $search_form->isValid()) {
$search_form->getData();
//save post/get form data without empty fields
$filter_array[$search_form->getName()]=array_filter(
$request->get($search_form->getName()),
function($value) { return $value !== ''; });
//... etc
}
Solution 1- make forms in your page links and add hidden fields with $filter_array
Solution 2- in page links use a script to add a hidden form field with page number and submit the form, simple but the form could be modified before click.
Solution 3- Put the paginator navigation and search results in a div, use jquery.load() for all actions (send form, page links, $( document ).ready() ...). The url will look like domain/page/#page_1:
{% for i in range(1, paginator.getTotalPages()) %}
<li {% if paginator.getPage() == i %} class="active"{%endif%}>
<a href="#page_{{i}}" onClick="
$('{{selector}}').load('{{ paginationPath }}',
{{filter_array|merge({page: i,})|json_encode()}});"
href="#page_{{i}}">{{ i }}</a>
</li>
{%endfor%}
