Question

I need to copy table contents from table: user_openletter to table: country on clicking archive button. How to write a query to copy from,to,title,openletter,open_id from user_openletter to another table country. This a codeigniter app.
my controller code is :
public function store_user_data_archieve()
{
$match = $this->input->post('submit');
echo $match;
if($match == "Archieve")
{
$data = array(
'open_id' => $this->input->post('open_id'),
'featured' => '1',
'from' => $this->input->post('from'),
'to' => $this->input->post('to'),
'title' => $this->input->post('title'),
'archieve' => '1',
'latest' => '0',
'sponsor' => 'images/sponsor.png'
);
$this->load->database();
//load the model
$this->load->model('select');
//load the method of model
$data['r']=$this->select->store_user_data_archieve($data);
echo "success";
}
else if(!$match == "new")
{
$data = array(
'open_id' => $this->input->post('open_id'),
'featured' => '1',
'from' => $this->input->post('from'),
'to' => $this->input->post('to'),
'title' => $this->input->post('title'),
'openletter' => $this->input->post('openletter'),
'archieve' => '0',
'latest' => '1',
'sponsor' => 'images/sponsor.png'
);
$this->load->database();
//load the model
$this->load->model('select');
//load the method of model
$data['r']=$this->select->store_user_data_archieve($data);
echo "success";
}
else if(!$match == "Discard")
{
echo "failure";
}
}
My view code is:
<?php
foreach ($r->result() as $row)
{
?>
<table border="1" cellpadding="4" cellspacing="0">
<tr>
<td>from</td>
<td>to</td>
<td>title</td>
<td>openletter</td>
<td>Date & Time</td>
<td>open_id</td>
</tr>
<tr>
<form action="/index.php/welcome/store_user_data_archieve" method="post">
<td><input type="text" name="from" value="<?php echo $row->from;?>" /></td>
<td><input type="text" name="to" value="<?php echo $row->to;?>" /></td>
<td><input type="text" name="title" value="<?php echo $row->title;?>" /></td>
<td><input type="text" name="openletter" value="<?php echo $row->openletter;?>" /></td>
<td><input type="text" name="datetime" value="<?php echo $row->datetime;?>" /></td>
<td><input type="text" name="open_id" value="<?php echo $row->open_id;?>" /></td>
<td><div><input type="submit" name="submit" value="Archieve" /></div></td>
<td><div><input type="submit" name="new" value="new" /></div></td>
</form>
</tr>
</table>
<?php } ?>
My model code is:
public function store_user_data_archieve($data)
{
//data is retrieved from this query
$this->db->insert('country', $data);
$this->db->set('openletter');
$this->db->select('openletter');
$this->db->where('open_id', $data[open_id]);
$this->db->from('user_openletter');
// Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')
}

Answer 1

As per our discussion you need to copy from,to,title,openletter,open_id from table user_openletter to country table
$this->db->select('from,to,title,openletter,open_id');// select your filed
$q = $this->db->get('user_openletter')->result(); // get result from table
foreach ($q as $r) { // loop over results
$this->db->insert('country', $r); // insert each row to country table
}

Answer 2

$this->db->select('from, to, title,openletter, open_id');
$result_set = $this->db->get('user_openletter')->result();
if(count($result_set) > 0) {
$this->db->insert_batch('country', $result_set);
}
