A Database Error Occurred Error Number: 1146 in codeigniter - codeigniter

Question

I am new to codeigniter where I tried form validation.
Here is my View Code:
<?php echo validation_errors(); ?>
<?php echo form_open('enquiry'); ?>
<table width="580" border="0" cellspacing="0" cellpadding="5">
<tr>
<td height="30" align="right" valign="middle" class="normal-text-style"> *Full Name:<br /></td>
<td height="30" align="left" valign="middle" class="normal-style"><input type="text" name="name" value="<?php echo set_value('name'); ?>" class="textbox-style01" /></td>
</tr>
<tr>
<td height="30" align="right" valign="middle" class="normal-text-style"> *Company: <span id="mndCompany"> </span><br /></td>
<td height="30" align="left" valign="middle" class="normal-style"><input type="text" name="company" value="<?php echo set_value('company'); ?>" class="textbox-style01" /></td>
</tr>
<tr>
<td height="30" align="right" valign="middle" class="normal-text-style"> *E-mail:</td>
<td height="30" align="left" valign="middle" class="normal-style"><input type="text" name="email" value="<?php echo set_value('email'); ?>" class="textbox-style01" /></td>
</tr>
<tr>
<td height="30" align="right" valign="middle" class="normal-text-style"> *Phone: <br /></td>
<td height="30" align="left" valign="middle" class="normal-style"><input type="text" name="phone" value="<?php echo set_value('phone'); ?>" class="textbox-style01" /></td>
</tr>
<tr>
<td height="30" align="right" valign="middle" class="normal-text-style"> *Fax: <br /></td>
<td height="30" align="left" valign="middle" class="normal-style"><input type="text" name="fax" value="<?php echo set_value('comments'); ?>" class="textbox-style01" /></td>
</tr>
<tr>
<td width="179" height="30" rowspan="2" align="right" valign="top" class="normal-text-style"> *Comments: <br /></td>
<td width="421" height="12" align="left" valign="middle" class="normal-style"><textarea name="comments" class="msgebox-style01"><?php echo set_value('comments'); ?></textarea></td>
</tr>
<tr>
<td height="50" align="left" valign="top" class="normal-style"><input type="image" name="submit" src=" <?php echo base_url(); ?>/public/images/submit01.png" alt="submit" /></td>
</tr>
</table>
</form>
And this is my controller
function index()
{
$this->form_validation->set_rules('name', 'Name', 'trim|required|xss_clean');
$this->form_validation->set_rules('company', 'Company', 'trim|required|xss_clean');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');
$this->form_validation->set_rules('phone', 'phone', 'trim|required|xss_clean');
$this->form_validation->set_rules('fax', 'fax', 'trim|required|xss_clean');
$this->form_validation->set_rules('comments', 'comments', 'trim|required|xss_clean');
$data['header_menu']=$this->load->view('header_menu', '', TRUE);
$this->load->view('inner_header',$data);
$data['left_menu']=$this->load->view('left_menu', '', TRUE);
if ($this->form_validation->run() == FALSE)
{
$this->load->view('enquiry',$data);
}
else
{
$this->load->view('enquiry/formsucess',$data);
}
$this->load->view('footer');
//$this->load->view('enquiry',$data);
}
function formsucess()
{
$name = $this->input->post('name');
$company = $this->input->post('company');
$email = $this->input->post('email');
$phone = $this->input->post('phone');
$fax = $this->input->post('fax');
$comments = $this->input->post('comments');
$this->db->query("INSERT INTO `st_enquiry`
(name, company,email,phone,fax,comments,status,created_on)
VALUES
('$name','$company','$email','$phone','$fax','$comments','1',now())");
$data['header_menu']=$this->load->view('header_menu', '', TRUE);
$this->load->view('inner_header',$data);
$data['left_menu']=$this->load->view('left_menu', '', TRUE);
$this->load->view('media',$data);
$this->load->view('footer');
}
After submitting the form I got an error like:
A Database Error Occurred
Error Number: 1146
Table 'table.users' doesn't exist

Answer 1

checkout this link
Here
$data = array(
'title' => 'My title' , // column_name => value
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('tablename', $data);
must work in any condition.

Answer 2

$this->form_validation->set_rules('email','Email','required|valid_email|is_unique[users.email]');
Here will be some change
is_unique[users.email]
01.here users mean your table name
02. email means email column in your table.
so it will be
$this->form_validation->set_rules('email','Email','required|valid_email|
is_unique[table name.email column in your table]');

Answer 3

A Database Error Occurred
Error Number: 1146
Table 'table.users' doesn't exist
I solved this problem in Codeigniter by changing name of table in phpmyadmin
i hope this can help you

Answer 4

Create a function in Model like:
$this->db->insert($this->table_name,$db_data);
return $this->db->insert_id();
and send data from Controller to Model
