I have problem with edit my post with it's attachment. this is my scripts on controller
Code:
function edit_post()
{
$data['css'] = $this->css;
$data['base'] = $this->base;
$data['title'] = "Admin";
$data['heading'] = "Edit Post";
$data['message'] = "";
$data['upload_error'] = "";
$query=$this->cr_posts_model->get_by_id($this->uri->segment(4));
foreach($query as $row):
$data['post_title'] =$row->title;
$data['body'] =$row->body;
$data['status']=$row->status;
$data['attach']=$row->attachment;
endforeach;
//form post
$data['input_title'] = array(
'name' => 'title',
'id' => 'title',
'maxlength' => '50',
'size' => '50',
'style' => 'width:50%'
);
$data['input_body'] = array(
'name' => 'body',
'id' => 'body',
'rows' => '50',
'cols' => '600',
'style' => 'width:100%'
);
$data['input_attachment'] = array(
'name' => 'attachment',
'id' => 'attachment',
'maxlength' => '100',
'size' => '50',
'type' => 'file',
'style' => 'width:50%'
);
$data['post_status'] = array(
'publish' => 'Publish',
'unpublish' => 'Unpublish',
);
$this->form_validation->set_rules('title', 'Title', 'trim|required');
$this->form_validation->set_rules('body', 'Body', 'trim|required');
$this->form_validation->set_rules('attachment', 'Attachment', 'trim');
if ($this->form_validation->run() == FALSE || !$this->upload->do_upload('attachment'))
{
$data['upload_error'] = array('error' => $this->upload->display_errors());
$this->load->view('admin/cr_edit_view', $data);
}
else //submit success
{
//upload
//$this->upload->do_upload('attachment');
$data['details'] = $this->upload->data();
//end upload
$post_id = $this->cr_posts_model->get_next_id();
$this->cr_posts_model->update();
$query=$this->cr_posts_model->get_by_id($this->uri->segment(4));
foreach($query as $row):
$data['post_title'] =$row->title;
$data['body'] =$row->body;
$data['status']=$row->status;
$data['attach']=$row->attachment;
endforeach;
if($_POST['button']=="Save"){
$data['message'] = "Your post has been saved . Continue editing or <a >base."public/company_report/full_page/".$this->uri->segment(4)."'>View Now</a> ?";
}
$this->load->view('admin/cr_edit_view', $data);
}
}
And in my model
Code:
function update()
{
$details = $this->upload->data();
$query=$this->cr_posts_model->get_attach($this->uri->segment(4));
foreach($query as $row):
$attach=$row->attachment;
endforeach;
if($details['file_name']!=""){
unlink($this->config->item('upload').str_replace($this->base."files/","",$attach));
$data = array(
'title' => $_POST['title'],
'body' => $_POST['body'],
'status' => $_POST['status'],
'attachment' => $this->base."files/cr_attachments/".$details['file_name'],
'modified' => date("Y-m-d H:i:s"),
'modified_by' => $this->session->userdata('user_id')
);
}else{
$data = array(
'title' => $_POST['title'],
'body' => $_POST['body'],
'status' => $_POST['status'],
'modified' => date("Y-m-d H:i:s"),
'modified_by' => $this->session->userdata('user_id')
);
}
$this->db->update('cr_posts',$data, array('post_id' => $this->uri->segment(4)));
}
It's working, i can delete my file if i change text field attachment and it's replace with new one. But I have problem with empty text field attachment. I want to by pass empty text field attachment and keep post updated with old attachment, but by default code igniters $this->upload->display_errors() always catch error "You did not select a file to upload."
any solution for this?
thx for help^^
