我正在预订机票，并且有 2 个单选按钮。
1)一种方法
2) 往返
我所做的事情是，当我选择往返时，所有字段都在那里(出发、返回和乘客数量)，但当我选择单程单选按钮时，返回字段应该隐藏。
在我的 Controller 中，我验证了所有字段都是必需的。问题是，每当我尝试以一种方式搜索(返回字段被隐藏)时，它都会给我一个“需要返回字段”错误
问题:当我选择“单向”单选按钮时，如何防止返回字段中的验证？

隐藏返回字段时我的ajax/js
<script type="text/javascript">
$(document).on('change', 'input:radio[name=flight_type]', function(){
$('div[id^="try"]').toggle(); // hide all DIVs begining with "my_radio_"
$('#' + $(this).attr('id') + '_text').show(); // show the current one
});
</script>
最佳答案
首先，您必须为往返旅程增加值(value):
<input type="radio" name="flight_type" value="round_trip" class="roundw" style="" checked>Round Trip
然后执行如下验证条件:
// Global validation for this method
if ($_POST['flight_type'] == 'round_trip')
{
$this->form_validation->set_rules('depart', 'Date of flight', 'required|trim');
$this->form_validation->set_rules('return', 'Date of return', 'required|trim');
}
else if($_POST['flight_type'] == 'one_way'){
// add validation for one way trip
}
关于php - 当您有隐藏字段时阻止验证 Codeigniter，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44449729/
