Image Upload in CodeIgniter

by Bhumi // Mar 19,2013 // No comment

CodeIgniter makes it easy to add images to your site. You can upload them using code I am going to explain here in this post.If you want to upload image in codeigniter,you need to write below html code into your view file which will create field to upload image.


<html>
<head>
</head>
<body>
	<form name="upload" id="upload" method="post" action="/user/test1" enctype="multipart/form-data">
		Select File <input type="file" name="txtImage" size="20" />
		<input type="submit" value="submit" />
	</form>
</body>
</html>

<html>

<head>

</head>

<body>

Select File <input type="file" name="txtImage" size="20" />

</form>

</body>

</html>

Now in the form action, at the PHP side, your code should be this. Here txtImage is your input field name. You have to provide upload_path, allowed types, max_size etc. You can ecrypt the file name by passing encrypt_name = true. The else part creates image thumbnail for specified height and width.


if($_FILES['txtImage']['name'] != "")
{
	$config['upload_path'] = 'images/upload/';
	$config['allowed_types'] = 'gif|jpg|png|jpeg';
	$config['max_size'] = '2000';
	$config['remove_spaces'] = true;
	$config['overwrite'] = false;
	$config['encrypt_name'] = true;
	$config['max_width']  = '';
	$config['max_height']  = '';
	$this->load->library('upload', $config);
	$this->upload->initialize($config);			
	if (!$this->upload->do_upload('txtImage'))
	{
		$error = array('error' => $this->upload->display_errors());
		print_r($error);
		exit();
	}
	else
	{
		$image = $this->upload->data();
		if ($image['file_name'])
		{
			$data['file1'] = $image['file_name'];
		}		
		$product_image = $data['file1'];
		$config['image_library'] = 'gd2';
		$config['source_image'] = '/images/upload/'.$data['file1'];
		$config['new_image'] = '/images/upload/new/';
		$config['maintain_ratio'] = FALSE;
		$config['overwrite'] = false;
		$config['width'] = 280;
		$config['height'] = 280;
		$this->load->library('image_lib', $config); //load library
		$this->image_lib->clear();
		$this->image_lib->initialize($config);
		$this->image_lib->resize(); //do whatever specified in config
		echo "all the things go well.";
	}
}

if($_FILES['txtImage']['name'] != "")

{

$config['upload_path'] = 'images/upload/';

$config['allowed_types'] = 'gif|jpg|png|jpeg';

$config['max_size'] = '2000';

$config['remove_spaces'] = true;

$config['overwrite'] = false;

$config['encrypt_name'] = true;

$config['max_width'] = '';

$config['max_height'] = '';

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

$this->upload->initialize($config);

if (!$this->upload->do_upload('txtImage'))

{

$error = array('error' => $this->upload->display_errors());

print_r($error);

exit();

}

else

{

$image = $this->upload->data();

if ($image['file_name'])

{

$data['file1'] = $image['file_name'];

}

$product_image = $data['file1'];

$config['image_library'] = 'gd2';

$config['source_image'] = '/images/upload/'.$data['file1'];

$config['new_image'] = '/images/upload/new/';

$config['maintain_ratio'] = FALSE;

$config['overwrite'] = false;

$config['width'] = 280;

$config['height'] = 280;

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

$this->image_lib->clear();

$this->image_lib->initialize($config);

$this->image_lib->resize(); //do whatever specified in config

echo "all the things go well.";

}
