问题描述：

I am new in Codeigniter and I have gone through its documentation. I'm trying to submit a form which is in HTML and jQuery but once I click the submit button nothing happens and my code seems fine. I also have a date and time picker which I would like to ask: should I store both in one column with a date and time as its type? or should they be stored separately? Here is my view:

<link href="<?php echo base_url() ?>assets/css/bootstrap-timepicker.min.css" rel="stylesheet">
<link href="<?php echo base_url() ?>assets/css/datepicker3.css" rel="stylesheet">
<link href="<?php echo base_url() ?>assets/tagsinput/bootstrap-tagsinput.css" rel="stylesheet">

<script type="text/javascript" src="<?php echo base_url() ?>assets/js/bootstrap-timepicker.js"></script>
<script type="text/javascript" src="<?php echo base_url() ?>assets/js/bootstrap-datepicker.js"></script>

<script type="text/javascript" src="<?php echo base_url() ?>assets/js/typeahead.js/bloodhound.min.js"></script>
<script type="text/javascript" src="<?php echo base_url() ?>assets/js/typeahead.js/typeahead.bundle.min.js"></script>
<script type="text/javascript" src="<?php echo base_url() ?>assets/js/typeahead.js/typeahead.jquery.min.js"></script>

<script type="text/javascript" src="<?php echo base_url() ?>assets/tagsinput/bootstrap-tagsinput-angular.min.js"></script>
<script type="text/javascript" src="<?php echo base_url() ?>assets/tagsinput/bootstrap-tagsinput.min.js"></script>

Your line:

<form name="SendSMSForm" id="SendSMSForm" action="<?phpecho form_open('comments/create_comment'); ?>" class="form-horizontal" role="form" method="post">

should not have form_open in action attribute. This will only generate the following:

    <form name="SendSMSForm" id="SendSMSForm" action="<form action="http://localhost/comments/create_comment" method="post" accept-charset="utf-8">
" class="form-horizontal" role="form" method="post">

form_open() is a native CI helper and helps you generate a form tag. https://www.codeigniter.com/userguide3/helpers/form_helper.html?highlight=form_open#form_open

Here's the proper syntax:

form_open($action = '', $attributes = array(), $hidden = array())

To create a form tag, you should do this:

<!-- Remove the form tag and use CI's form helper -->
<?php echo form_open(NULL, array('name'=>'SendSMSForm', 'id'=>'SendSMSForm', 'class'=>'form-horizontal', 'role'=>'form')); ?>

This should generate the following:

<form action="http://localhost/" name="SendSMSForm" id="SendSMSForm" class="form-horizontal" role="form" method="post" accept-charset="utf-8">

This is a CodeIgniter way. You can still use the <form> tag.
