Cant validate form data or insert into database (Codeigniter) - php

Question

I am working with Codeigniter framework these days. I am trying to validate my form data using codeigniter's form_validation library. The problem is I cant get it to work. I dont know where the problem is no error is being shown.
Here is the view page I am calling controller core and function postad in form action
<div class="container table-responsive" id="con1">
<div class="row" id="h4_subad">
<div class="col-md-4"><h4>Submit an Ad</h4></div>
</div>
<form class="form-horizontal" role="form" method="get" action="/core/postad">
<table id="form_table" class="table-responsive table table-striped" id="table_form">
<td>Ad Title*</td><td><input class="form-control" name="ad_title" id="ad_title" type="text" placeholder="Enter Title" id="ad_form"></td>
<tr> <td>Select Category*</td> <td><select name="ad_form" class="form-control" id="ad_form">
<option>Electronics</option>
<option>Mobiles & Accessories</option>
<option>Computers & Accessories</option>
<option>Kitchen Applicances</option>
<option>Clothing</option>
</select></td></tr>
<tr><td>Ad Description*</td><td><textarea name="txt_area" id="txt_area" class="form-control" type="text" placeholder="Enter Description" ></textarea></td></tr>
<tr><td><button type="button" class="btn btn-warning" onclick="core/postad">Submit Ad</button></td></tr>
</table>
</form>
</div>
Controller for this view
class Core extends CI_Controller {
public function index() {
$this->load->view('header1');
$this->load->view('body');
$this->load->view('footer');
}
public function product() {
$this->load->view('header1');
$this->load->view('product');
$this->load->view('footer');
}
public function contact() {
$this->load->view('header1');
$this->load->view('contact');
$this->load->view('footer');
}
public function aboutus() {
$this->load->view('header1');
$this->load->view('aboutus');
$this->load->view('footer');
}
public function reg() {
$this->load->view('header1');
$this->load->view('reg');
$this->load->view('footer');
$this->input->get('username');
}
public function postad() {
$this->load->view('header1');
$this->load->view('postad');
$this->load->view('footer');
$this->load->model('insert_model');
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
//Validating Name Field
$this->form_validation->set_rules('txt_area', 'Text Area', 'required|min_length[5]|max_length[15]');
if ($this->form_validation->run() == FALSE) {
$this->load->view('postad');
}
else {
//Setting values for tabel columns
$data = array(
'description' => $this->input->post('txt_area'),
);
//Transfering data to Model
$this->insert_model->form_insert($data);
$data['message'] = 'Data Inserted Successfully';
//Loading View
$this->load->view('insert_view', $data);
}
}
}
Model for database connectivity
<?php
class insert_model extends CI_Model{
function __construct() {
parent::__construct();
}
function form_insert($data){
$this->db->insert('post_ad', $data);
}
}
?>
Only trying it for just one field txt_area
I dont want to use codeigniter's form helper as I am using bootstrap form.

You should echo the validation_errors(); as below in your html . For more information you can vist this
<?php echo validation_errors(); ?>
<div class="row" id="h4_subad">
<div class="col-md-4"><h4>Submit an Ad</h4></div>
</div>
<form class="form-horizontal" role="form" method="get" action="/core/postad">
<table id="form_table" class="table-responsive table table-striped" id="table_form">
<td>Ad Title*</td><td><input class="form-control" name="ad_title" id="ad_title" type="text" placeholder="Enter Title" id="ad_form"></td>
<tr> <td>Select Category*</td> <td><select name="ad_form" class="form-control" id="ad_form">
<option>Electronics</option>
<option>Mobiles & Accessories</option>
<option>Computers & Accessories</option>
<option>Kitchen Applicances</option>
<option>Clothing</option>
</select></td></tr>
<tr><td>Ad Description*</td><td><textarea name="txt_area" id="txt_area" class="form-control" type="text" placeholder="Enter Description" ></textarea></td></tr>
<tr><td><button type="button" class="btn btn-warning" onclick="core/postad">Submit Ad</button></td></tr>
</table>
</form>
</div>

Answer 2

You need to use validation_errors(); in posted.php file (HTML) for display error message which you validate.
<?php echo validation_errors(); ?>
Form Validation User Manual

Answer 3

Your button to submit the form is incorrect. When you try to submit a form make sure to set the type to submit too.
<button type="submit">Submit form</button>
or
<submit>Submit form</submit>
