passing variables in form_open() in codeigniter - php

Question

Good day all. I'm new to codeigniter and I'm trying to pass a variable from one view page to another. But I get error and after a lot of tries still couldn't figure it out.
This is the Model code:
function get_post($postID){
$this->db->select()->from('khanposts')->where(array('post_id'=>$postID))->order_by('fullname', 'desc');
$query=$this->db->get();
return $query->result_array();
}
function update_post($postID, $data)
{
$this->where('post_id', $postID);
$this->db->update('khanposts', $data);
}
This is the Controller code:
function editpost($postID)
{
$data['success']=0;
if($_POST){
$data_post=array(
'fullname'=>$_POST['fullname'],
'dob'=>$_POST['dob'],
'blood'=>$_POST['blood'],
'village'=>$_POST['village'],
'occupation'=>$_POST['occupation'],
'company'=>$_POST['company'],
'email'=>$_POST['email'],
'contact'=>$_POST['contact'],
'password'=>$_POST['pass'],
'marry'=>$_POST['marry']);
$this->khanpost->update_post($postID, $data);
$data['success']=1;
}
$data['post']=$this->khanpost->get_post($postID);
$this->load->view('edit_post', $data);
}
This is the code of View page which passes the value to edit_post view page:
foreach ($posts as $row){
<tr><td><i>Edit</i></td></tr>';
}
This is code of edit_post view page where it must get the value of $row['post_id']:
echo form_open(base_url().'khanposts/editpost/'.$row['post_id']);
echo '<b>Full Name: </b>';
$data_form=array('name'=>'fullname', 'size'=>30, 'id'=>'fullname', 'class'=>'inputstyle', 'value'=>$row['fullname'] );
echo form_input($data_form);
How do I assign the passsed variable($row['post_id']) in form_open()? Any solution will be really helpful. Tnx.

Answer 1

As far as I understand the problem;
Pass PostID to view in editpost function:
function editpost($postID)
{
...
$data['postID'] = $postID;
}
Get it in view page like:
echo form_open(base_url('khanposts/editpost/'.$postID));
You should load form helper:
$this->load->helper('form');
And your data_form input:
$data_form = array('name'=>'fullname', 'size'=>30, 'id'=>'fullname', 'class'=>'inputstyle', 'value' => $post['fullname']);
You should use row_array instead of result_array, because of you get single post.
function get_post($postID)
{
$this->db->select()->from('khanposts')->where(array('post_id'=>$postID))->order_by('fullname', 'desc');
$query=$this->db->get();
return $query->row_array();
}
