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
在带有codeigniter的bootstrap模型表单上,如果输入的用户名不正确,则应显示消息。但是,如果我单击按钮,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true,则不会关闭bootstrap模式,但如果form_validation正常,那么让我提交。

Error_validation
is a feature that CI provides.
Error_validation是CI提供的功能。
You can only use error_validation
of code igniter when the page is submitted hence, the bootstrap modal is automatically closed because the page is getting submitted.
因此,在提交页面时,您只能使用代码点火器的error_validation,因为页面正在提交,因此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:
<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;
}
}
});
});
});
