image view problem

cerberus478 · July 24, 2012

Hi

My problem is that I want to view an image, but when I view it I get a bunch of gibberish.

I'm using codigniter.

I set my image column as a BLOB.

This is my bras controller

<?php
class Bras extends CI_Controller {

public function __construct()
{
	parent::__construct();
	$this->load->model('bras_model');
}

public function index()
{
	$data['bras'] = $this->bras_model->get_bras();
	$data['title'] = 'bras archive';

$this->load->view('templates/header', $data);
$this->load->view('bras/index', $data);
$this->load->view('templates/footer');
}

public function view($slug)
{
$data['bras_item'] = $this->bras_model->get_bras($slug);

if (empty($data['bras_item']))
{
	show_404();
}

$data['title'] = $data['bras_item']['title'];

$this->load->view('templates/header', $data);
$this->load->view('bras/view', $data);
$this->load->view('templates/footer');
}

public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');

$data['title'] = 'Create a bra item';

$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('content', 'content', 'required');

if ($this->form_validation->run() === FALSE)
{
	$this->load->view('templates/header', $data);	
	$this->load->view('bras/create');
	$this->load->view('templates/footer');

}
else
{
	$this->bras_model->set_bras();
	$this->load->view('bras/success');
}
}
}

This is my bras_model

<?php
class Bras_model extends CI_Model {

public function __construct()
{
	$this->load->database();
}

public function get_bras($slug = FALSE)
{
if ($slug === FALSE)
{
	$query = $this->db->get('bras');
	return $query->result_array();
}

$query = $this->db->get_where('bras', array('slug' => $slug));
return $query->row_array();
}

public function set_bras()
{
$this->load->helper('url');

$slug = url_title($this->input->post('title'), 'dash', TRUE);

$data = array(
	'title' => $this->input->post('title'),
	'slug' => $slug,
	'content' => $this->input->post('content')
);

return $this->db->insert('bras', $data);
}
}

This is my view

<?php
echo '<h2>'.$bras_item['title'].'</h2>';
echo $bras_item['image'];
echo $bras_item['content'];

?>

Question: Why are you storing the image in the database? That's unnecessary bloat.

This 'gibberish' you are viewing are the binary forms of the images. You could store the images in a folder and recall the images from there (preferred) - or you'll need to set headers (ill advised)

Then is there a way to store the path of the image on the database?

of course there is. it's just letters that make words, which are just strings, right?

I've maneged to get the pics to uplaod into a folder on the server, but I'm not sure on how to put the folder path into the database.

This is my upload controller

<?php

class Upload extends CI_Controller {

function __construct()
{
	parent::__construct();
	$this->load->helper(array('form', 'url'));

}

function index()
{
	$this->load->view('upload_form', array('error' => ' ' ));


}

function do_upload()
{
	$config['upload_path'] = './uploads/';
	$config['allowed_types'] = 'gif|jpg|png';
	$config['max_size']	= '100';
	$config['max_width']  = '1024';
	$config['max_height']  = '768';

	$this->load->library('upload', $config);

	if ( ! $this->upload->do_upload())
	{
		$error = array('error' => $this->upload->display_errors());

		$this->load->view('upload_form', $error);
	}
	else
	{
		$data = array('upload_data' => $this->upload->data());

		$this->load->view('upload_success', $data);
	}
}
}
?>

and this is the upload_form

<html>
<head>
<title>Upload Form</title>
</head>
<body>

<?php echo $error;?>

<?php echo form_open_multipart('upload/do_upload');?>

<input type="file" name="userfile" size="20" />

<br /><br />

<input type="submit" value="upload" />

</form>

</body>
</html>

You tell it to. You've already got $config['upload_path'] = './uploads/', and $this->upload->data(); contains the file name.
