You can try this solution for your problem :
Controller :
<?php
public function insert_news() {
$config['upload_path'] = 'uploads/news/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '20240000245';
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;
// You can change width & height
$imgage_width= 60;
$imgage_height= 60;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!$this->upload->do_upload($field)) {
$error = $this->upload->display_errors();
// uploading failed. $error will holds the errors.
$this->form_validation->set_message('error',$error);
return FALSE;
} else {
$fdata = $this->upload->data();
$configer = array(
'image_library' => 'gd2',
'source_image' => $fdata['full_path'],
'maintain_ratio' => TRUE,
'width' => $imgage_width,
'height' => $imgage_height,
);
// Load Image Lib Library
$this->load->library('image_lib');
$this->image_lib->clear();
$this->image_lib->initialize($configer);
$this->image_lib->resize();
$img_data ['path'] = $config['upload_path'] . $fdata['file_name'];
// uploading successfull, now do your further actions
$data=array(
'news_title' => $this->input->post('news_title'),
'news_content' => $this->input->post('news_content'),
'news_image' => $img_data ['path'],
'news_sef'=>sef($this->input->post('news_title'))
);
$this->load->model('vt');
$result = $this->vt->insert_news($data);
if ($result) {
$this->form_validation->set_message('success',"News has been added successfully.");
redirect('contorller/action_name');
} else {
$this->form_validation->set_message('error',"Error in aading news");
redirect('contorller/action_name');
}
}
}
?>
I Hope it will Help you.
