Code Igniter - How to save images into database - php

Question

I'm making use of codeIgniter to upload files into folders in the server. Now I also want to save the data into the database, what do I need in order to get the raw data and then save it into the database?
Here's the model for saving files:
<?php
class files extends ci_Model{
function saves($filename, $filedata, $post_id){
$this->db->query("INSERT INTO tbl_files SET file_data='$filedata', filename='$filename', postid='$post_id'");
}
}
?>
Here's how I call it from the upload controller:
$filename = $data['upload_data']['file_name'];
$file_data = file_get_contents($data['upload_data']['file_name']);
$this->load->model('files');
$this->files->saves($filename, $file_data, 'ID1');
Table Structure:
file_data (LONG BLOB)
filename (VARCHAR)

Try it , it's work on my code`
function _save($id = null){
$config['upload_path'] = './asset/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if($_POST || $_FILES){
if(!$this->upload->do_upload('field_input_name')){
echo $this->upload->display_errors('<p>', '</p>');
} else {
$w = $this->upload->data();
$data = array(
'field_input_name' => $w['file_name'],
);
$this->db->insert('table_image', $data);
}
}
}

I have solved the problem by using the handy mysql_real_escape_string() like this:
$filename = $data['upload_data']['file_name'];
$file_data = mysql_real_escape_string(file_get_contents($data['upload_data']['full_path']));
