我最初依靠页面刷新，然后根据php控制器文件中的验证函数在地址添加/编辑表单上显示任何错误(如果不满足所需字段(。然后，我调整了我的表单，使用引导模式，而不是动态加载的表单，我可以非常出色地提交数据。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，这反过来会阻止模态关闭，并且看起来不会提交任何内容。我查看了这个链接：ZF2-在引导模式中进行验证，但它似乎不适合我的需求。我真的希望避免使用jquery来完全以某种方式在客户端验证我的表单。我只需要将jquery与ajax调用一起使用，以某种方式检查我现有的php控制器文件，并直接在我的模态中显示任何错误，同时如果发现此类错误，也会阻止表单提交。

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。我将jquery 2.1.1和bootstrap 3.3.0用于我的这个特定项目，但如果有人能为我指明正确的方向，我可以调整任何答案。
更新：我在下面标出了正确的答案，这对我帮助很大。为了包含我对答案所做的操作，我将错误封装在空的div中，并简单地使用.html填充发现的任何错误。
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>
已更改为：
<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，我所需要做的就是不断添加我的.html，用于我需要填充的所有错误div，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 }}');
}
});
你说得对。从服务器向客户端发送JSON响应。您可以指定验证是否成功，将原因与等一起发送
在后端，如果你使用Symphony，你可以发送这样的响应：
return new JsonResponse(array('success' => false, 'message' => 'Invalid EMail'));
因此，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PHP处理的模板的错误显示部分。让前端处理错误的显示。
修改您的ajax调用代码。。
$.ajax({
type: request_method,
url: "post_url",
data: form_data,
cache: false,
success: function(result){
if(result===1){
// On success redirect...return 1 from backend if no errors are there.
$('#addAddressModal').modal('hide');
}
else
//display error message..create response 'result' in backend such that you can display all errors
//for eg : foreach error append a number to response and in client side use js include to check if certain error is there or not.
}
});
它100%有效
