In CodeIgniter, upload library is useful to upload image.
We need to add multipart in form, so we can upload file:
<?php echo form_open_multipart('upload/do_upload'); ?>
and add input type as “file: to upload file:
<input type="file" name="profile_image" />
In controller function, you need to add upload library:
$this->load->library('upload', $config);
In $config, you add basic config setting:
$config['upload_path'] = './uploads/'; //folder path file to upload $config['allowed_types'] = 'gif|jpg|png'; //allowed file type or file extension $config['max_size'] = 100; $config['max_width'] = 300; $config['max_height'] = 400; $this->load->library('upload', $config);
After that, do_upload function uploads file on specific folder location and $upload_data gives uploaded file information or return error based on performed operation result.
if ( ! $this->upload->do_upload('profile_image')) { $error = array('error' => $this->upload->display_errors()); } else{ $upload_data = $this->upload->data(); }
Upload script:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 300;
$config['max_height'] = 400;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('userfile'))
{
$error = array('error' => $this->upload->display_errors());
} else {
$upload_data = $this->upload->data();
}
Hope this helps!
