當我回傳我的事件串列時，如何檢索通過搜索表單發送的資料？

我想知道如何使用表格events獲得event的結果回傳路由search。目前，當我嘗試從eventto回傳時events，我丟失了所有允許我根據其bigcity和類別查找事件的資料。

有沒有辦法檢索這些資訊？

事件.html.twig

{% extends 'base.html.twig' %}

{% block main %}

<a href="{{ path('events') }}" >&lt; Retour</a>

事件控制器.php

uj5u.com熱心網友回復：

每個事件都與一個類別和一個大城市相關，表單搜索表單只有這兩個欄位

所以，當你在show one event route時，你可以從當前的事件中知道什么是類別，什么是bigcity。

您可以像這樣在路徑中添加這兩個屬性 id：

<a href="{{ path('events', {'category': event.category.id, 'bigcity': event.bigCity.id}) }}">Retour</a>

或者您也可以使用“referer”，但這不會每次都有效，因為如果用戶顯示來自 borwser 歷史記錄或外部 url 的事件，或者如果他直接在瀏覽器 url 選項卡中鍵入 url

 <a href="{{ app.request.headers.get('referer') }}">Rtour</a>

或者使用 javascript
