Bootstrap Modal With Codeigniter Form Validation
提问by Mr. ED
On my bootstrap model form with codeigniter if username was entered incorrect it should show message. But when if I click on button the bootstrap modal goes away even if validation errors are displayed
在我的带有 codeigniter 的引导模型表单上，如果输入的用户名不正确，它应该显示消息。但是当我点击按钮时，即使显示验证错误，引导模式也会消失
Goal:What I would like to be able to do is if any form validation true then will not close bootstrap modal but then if form_validation is OK then let me submit.
目标：我希望能够做的是，如果任何表单验证为真，则不会关闭引导模式，但如果 form_validation 正常，则让我提交。

Error_validationis a feature that CI provides.
Error_validation是 CI 提供的一个特性。
You can only use error_validationof code igniter when the page is submitted hence, the bootstrap modal is automatically closed because the page is getting submitted.
您只能error_validation在提交页面时使用代码点火器，因此，由于页面正在提交，引导模式会自动关闭。
If you want to perform a form validation on a modal, it is better you use AJAX
如果要对模态执行表单验证，最好使用 AJAX
If you want to show the error message above the form_open, just make a blank div like:
如果要在 form_open 上方显示错误消息，只需创建一个空白 div，例如：
<div class='error_msg'>
</div>
and with jquery:
并使用 jquery：
$(function(){
$('#form_id').submit(function(event){
event.preventDefault();
var custemail = $('#email_id').val();
var custname = $('#name').val();
$.ajax({
type: 'POST',
url: your controller path,
data: {
'name': custname,
'email': custemail
},
dataType: 'html',
success: function(results){
if(something not as you expected){
$('.error_msg').html('error msg');
return false;
}
}
});
});
});
