分页时在会话中存储复选框值的最佳方法-PHP中文网问答

我与 Symfony 和 Twig 合作。我目前有一个包含产品列表的树枝页面，我使用 foreach 循环显示它们，并设置分页来限制产品的显示。

我在此页面中有一个表单，其中有一个复选框作为输入，当我转到下一页时，我需要在会话中选中保存复选框

我尝试通过添加此代码来做到这一点

有一些代码，我在分页视图和控制器中添加了一些注释来解释我的尝试。

我的循环视图：

<form>
    <div class="row" >
        {%  for annonce in annonces %}

            <div class="col-12 col-md-6 col-lg-4">
                        <p class="text text--blue text--bold m-0 text--medium mt-2">
                            {{ annonce._source.titre }}
                        </p>
                        <p class="m-0">{{ 'Réf' }}: {{ annonce._source.reference }}</p>
                        <div class="d-flex mt-2 text--bold">
                            <div class="d-flex me-2">
                                {{  annonce._source.ville }}
                            </div>
                        </div>
                    <div>
                        <input type="checkbox" name="checkbox[]" id="checkbox_pdf" value="{{annonce._id}}" multiple/>
                    </div>

            </div>

        {% endfor %}
    </div>
    <input type="submit" id="pdf_submit" value="Create PDF" name="submit_pdf" class="btn btn-primary">
</form>

分页视图：

// I tried to add a onclick : onclick='document.forms["name"].submit(); return false;' on each pagination link combined with the save of the value in session with my controller but doesn't work

<div class="col d-flex justify-content-between align-items-center">
    <div class="d-flex">
        {% if page > 0 %}
            <a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':0, 'type':'frontoffice'}) }}" data-target="pagination-target">
                «
            </a>
            <a href="#"  data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':page-1, 'type':'frontoffice'}) }}"  data-target="pagination-target">
                {{ 'Précédent' }}
            </a>
        {% else %}
            <a href="#" disabled="disabled" >
                {{ 'Précédent' }}
            </a>
        {% endif %}
    </div>
    <div>
        <ul class="list-unstyled pagination m-0">
            {% for i in (page+1)..(page+4) %}
                {% if i <= numberOfMaxPage %}
                    {% if i == (page+1) %}
                        <li>
                            <a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':(i-1), 'type':'frontoffice'}) }}" data-target="pagination-target">
                                {{ i }}
                            </a>
                        </li>
                    {% else %}
                        <li>
                            <a href="#"  data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':(i-1), 'type':'frontoffice'}) }}" data-target="pagination-target">
                                {{ i }}
                            </a>
                        </li>
                    {% endif %}
                {% endif %}
            {% endfor %}
        </ul>
    </div>
    <div class="d-flex">
        {% if page < (numberOfMaxPage-1) %}
            <a href="#"  data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':page+1, 'type':'frontoffice'}) }}" data-target="pagination-target">
                {{ 'Suivant' }}
            </a>
            <a href="#"  data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':numberOfMaxPage-1, 'type':'frontoffice'}) }}" data-target="pagination-target">
                »
            </a>
        {% endif %}
    </div>
</div>

分页的JS：

$( document ).ready(function() {
            $(document).on('click', 'a.pagination',function(e) {
                e.preventDefault();
                $.ajax({
                    url: $(this).data('uri'),
                }).done(function(html) {
                    $('#pagination-target').html(html);
                    $('html,body').animate({scrollTop: $('#pagination-target').offset().top - 80}, 200);
                    var $scrollable = document.getElementById('pagination-target');
                    $scrollable.scrollIntoView();

                });
            });
        });

在我的控制器中，我像这样渲染视图：

public function search(Request $request, ?SecteurGeographique $secteurGeographique, AnnonceRepository $annonceRepository): Response
    {
        $selectId = $request->get('checkbox');
        $selected = $annonceRepository->findById($selectId);

// I tried to add this code to save my values
        
if (isset($selectId))
        {
            $session = new Session();
            $session->set('checkbox',$selectId);
        }else{
            echo 'false';
            $session = new Session();
            $session->clear();
        }

return $this->render('front/annonce/list.html.twig', array(
                        'annonces' => $results['hits']['hits'],
                        'total'  => $results['hits']['total']['value'],
                        'website' => $website,
                        'page' => $request->query->getInt('page')
                    ));
}

在会话中保存我的 php 还是在 ajax 中更好？

提前谢谢您

$(document).ready(function() { $(document).on('click', 'a.pagination',function(e) { e.preventDefault(); // Save all the selected checkboxes by moving them to #savedCheckboxes $('.checkboxPDF:checked').appendTo($('#savedCheckboxes')) // Do your pagination like you did $.ajax({ url: $(this).data('uri'), }).done(function(html) { $('#pagination-target').html(html); // If the user come to a previous page, verify if he did selected a checkbox $('#pagination-target .checkboxPDF').each(function(i, element) { // If the checkbox already exists in the #savedCheckboxes, then select this checkBox & remove it from #savedCheckboxes var savedCheckbox = $('#savedCheckboxes .checkboxPDF[value="'+element.val()+'"]') if(savedCheckbox.length > 0) { element.click() // Select this checkbox savedCheckbox.remove() // Remove it from the hidden selection } }) $('html,body').animate({scrollTop: $('#pagination-target').offset().top - 80}, 200); var $scrollable = document.getElementById('pagination-target'); $scrollable.scrollIntoView(); }); }); });
