php - How do I tell which radio button was selected in file HTML-Twig -
i have 4 radio buttons in code html:
<input id="spa-price" name="price" class="w3-radio" value="spare {{ price.getspareprice }}" type="radio"> <input id="spa-price" name="price" class="w3-radio" value="repair {{ price.getrepairprice }}" type="radio"> <input id="spa-price" name="price" class="w3-radio" value="test {{ price.gettestprice }}" type="radio"> <input id="spa-price" name="price" class="w3-radio" value="std-exchange {{ price.getexchangeprice }}" type="radio"> on post, want output hidden field value of selected radio button, eg:
<input type="hidden" name="lt" value="{{ price.getlt }}"> the code have @ moment:
{% if $_post['price'] == 'spare' %} <input type="hidden" name="lt" value="{{ price.getlt }}"> {% elseif $_post['price'] == 'repair' %} <input type="hidden" name="lt" value="{{ 10 }}"> {% elseif $_post['price'] == 'test' %} <input type="hidden" name="lt" value="{{ 10 }}"> {% else $_post['price'] == 'exchange' %} <input type="hidden" name="lt" value="{{ price.getlt }}"> currently, not work.
what error ? thank you.
first, have given every checkbox made same id bad practice. in html every id should have unique name. suggest same names. optional
so change id's this:
<input id="spare-price" name="price" class="w3-radio" value="spare {{ price.getspareprice }}" type="radio"> <input id="repair-price" name="price" class="w3-radio" value="repair {{ price.getrepairprice }}" type="radio"> <input id="test-price" name="price" class="w3-radio" value="test {{ price.gettestprice }}" type="radio"> <input id="exchange-price" name="price" class="w3-radio" value="std-exchange {{ price.getexchangeprice }}" type="radio"> you can use javascript check if box checked
{% block javascripts%} <script> function validate(){ var spare= document.getelementbyid('spare-price'); if (spare.checked){ alert("checked") ; }else{ alert("you didn't check spare-price! let me check you.") } } </script> {% endblock %}
