I have been working on a cms for a small site and having a problem with the edit page and file upload.
My edit page shows the currently uploaded file and option to upload a new file. THe problem occurs if I submit an edit page without a putting a new file in the "file" field as it tried to do the upload in the model even though I have put if not null. My code is below, could anyone advise where I am going wrong please ?
THanks
Code:
function update()
{
$content = array('title' => $_POST['title'],
'category' => $_POST['category'],
'description' => $_POST['description'],
'order' => $_POST['order']);
if ($_FILES['myfile'] != NULL)
{
$config['upload_path'] = './includes/uploads/';
$config['allowed_types'] = 'gif|jpg';
$config['max_size'] = '1000';
$config['remove_spaces'] = true;
$config['overwrite'] = true;
//$config['max_width'] = '400';
//$config['max_height'] = '400';
$this->load->library('upload', $config);
if( ! $this->upload->do_upload('myfile'))
{
echo $this->upload->display_errors();
exit();
} else
{
// Thumbnail
$data = array('upload_data' => $this->upload->data());
$temp=$this->upload->data();
$thumb['image_library'] = 'GD2';
$thumb['source_image'] = './includes/uploads/'.$temp['file_name'];
$thumb['new_image'] = './includes/uploads/thumb/'.$temp['file_name'];
$thumb['maintain_ratio'] = TRUE;
$thumb['create_thumb'] = TRUE;
$thumb['quality'] = '100';
$thumb['height'] = '80';
$thumb['width'] = '80';
$this->load->library('image_lib', $thumb);
$this->image_lib->resize();
//making a thumbnail
$this->image_lib->clear();
//insert to the DB
$content['file'] = $temp['file_name'];
}
$this->db->where('id', $_POST['id']);
$this->db->update($this->table, $content);
}
}
