php - 使用 php 和 jquery 在引导模式中动态验证表单

我最初依赖于页面刷新,然后根据 php Controller 文件中的验证功能在我的地址添加/编辑表单上显示任何错误(如果未满足必填字段)。然后,我调整了我的表单以使用引导模式,而不是动态加载的表单,我可以出色地提交数据。然而,我遇到的一个小问题是,虽然后端验证会阻止更新/添加的数据实际提交表单,但它不会显示客户端验证错误,这反过来会阻止模式关闭和似乎没有提交任何内容。我查看了这个链接:ZF2 - validation within a bootstrap modal但它似乎不适合我的需要。我真的很想避免使用jquery完全以某种方式在客户端验证我的表单。我只需要使用 jquery 和 ajax 调用来以某种方式检查我现有的 php Controller 文件并直接在我的模式中显示任何错误,同时如果发现此类错误也阻止表单提交。

我的 php 文件中的相关代码:

public function getAddressForm() {
$this->load->language('customer/customer');

if (isset($this->request->get['customer_id'])) {
$customer_id = $this->request->get['customer_id'];
} else {
$customer_id = 0;
}

$this->load->model('customer/customer');

我的 Twig 文件上的相关代码使模态表单工作并提交数据,但无法显示客户端验证:

<script type="text/javascript"><!--
function update_address(id){

$('#updateAddressModal').modal();
$('#updateAddressModal .modal-body').load('index.php?route=customer/customer/editaddress&user_token={{ user_token }}&customer_id={{ customer_id }}&address_id='+id, function(){
$('#updateAddressModal #address_form').submit(function(e){

e.preventDefault();

var post_url = $(this).attr("action");
var request_method = $(this).attr("method");
var form_data = $(this).serialize();

$.ajax({
url : post_url,
type: request_method,
data : form_data
}).done(function(response){
$('#updateAddressModal').modal('hide');
$('#address').load('index.php?route=customer/customer/getaddresslist&user_token={{ user_token }}&customer_id={{ customer_id }}');

});
});

$('#updateAddressModal select[name=\'country_id\']').trigger('change');
});


}
//--></script>
<script type="text/javascript"><!--
function add_address(){
$('#addAddressModal').modal();
$('#addAddressModal .modal-body').load('index.php?route=customer/customer/addaddress&user_token={{ user_token }}&customer_id={{ customer_id }}', function(){
$('#addAddressModal #address_form').submit(function(e){

e.preventDefault();

var post_url = $(this).attr("action");
var request_method = $(this).attr("method");
var form_data = $(this).serialize();

$.ajax({
url : post_url,
type: request_method,
data : form_data
}).done(function(response){
$('#addAddressModal').modal('hide');
$('#address').load('index.php?route=customer/customer/getaddresslist&user_token={{ user_token }}&customer_id={{ customer_id }}');

});
});

$('#addAddressModal select[name=\'country_id\']').trigger('change');
});
}
//--></script>

我的模式形式的“操作”决定了模式是否添加或编辑现有地址。我确信答案就在它的某个地方,通过 ajax 调用检查验证,我猜(?),所以这就是我被难住的地方。:

我怀疑我可能需要在所有这些中使用 json 来显示错误,但我不确定。我在我的这个特定项目中使用 jquery 2.1.1 以及 bootstrap 3.3.0,但如果有人能指出我正确的方向,我可以调整向我抛出的任何答案.

更新:我在下面标记了正确的答案,这对我帮助很大。为了包含我对答案所做的操作,我将错误包含在空 div 中,并简单地使用 .html 用发现的任何错误填充它们。

示例:

  <div class="form-group required">
<label class="col-sm-4 control-label" for="input-postcode">{{ entry_postcode }}</label>
<div class="col-sm-8">
<input type="text" name="postcode" value="{{ postcode }}" placeholder="{{ entry_postcode }}" id="input-postcode" class="form-control" />
{% if error_postcode %}
<div class="text-danger">{{ error_postcode }}</div>
{% endif %}
</div>
</div>

更改为:

  <div class="form-group required">
<label class="col-sm-4 control-label" for="input-postcode">{{ entry_postcode }}</label>
<div class="col-sm-8">
<input type="text" name="postcode" value="{{ postcode }}" placeholder="{{ entry_postcode }}" id="input-postcode" class="form-control" />
<div id="error-postcode"></div>
</div>
</div>

然后,我需要做的就是继续为我需要填充的所有错误 div 添加 .html,如下所示:

        $.ajax({
url: post_url,
type: request_method,
data: form_data
}).done(function(response){
if(!response.success) {
//Dont close the modal, display the error
$('#error-postcode').html('{% if error_postcode %}<div class="text-danger">{{ error_postcode }}</div>{% endif %}');
}
else {
$('#addAddressModal').modal('hide');
$('#address').load('index.php?route=customer/customer/getaddresslist&user_token={{ user_token }}&customer_id={{ customer_id }}');
}

});

最佳答案

你是对的。将 JSON 响应从服务器发送到客户端。您可以指定验证是否成功,以及发送原因等

在后端,如果您使用 Symphony,您可以像这样发送响应:

return new JsonResponse(array('success' => false, 'message' => 'Invalid EMail'));

所以,客户端代码变成这样:

$.ajax({
url : post_url,
type: request_method,
data : form_data
}).done(function(response){

if(!response.success) {
//Dont close the modal, display the error
$('#err').html(response.message);
}
else {
$('#addAddressModal').modal('hide');
$('#address').load('index.php?route=customer/customer/getaddresslist&user_token={{ user_token }}&customer_id={{ customer_id
}
});
});

您几乎可以避免由 PHP 处理的模板的错误显示部分。让前端处理错误的显示。
