How to delete uploaded files with Codeigniter? - php

Question

I used the Codeigniter's Upload Class to upload images to a folder in the project. In the database I only store the the url generated after upload the image, so when I want to delete a row in the db I also need to delete the image. How can I do it in codeigniter?
I will be grateful for your answers.

Answer 1

You can delete all the files in a given path, for example in the uploads folder, using this deleteFiles() function which could be in one of your models:
$path = $_SERVER['DOCUMENT_ROOT'].'/uploads/';
function deleteFiles($path){
$files = glob($path.'*'); // get all file names
foreach($files as $file){ // iterate files
if(is_file($file))
unlink($file); // delete file
//echo $file.'file deleted';
}
}

Answer 2

delete_row_from_db(); unlink('/path/to/file');
/path/to/file must be real path.
For eg :
if your folder is like this htp://example.com/uploads
$path = realpath(APPPATH . '../uploads');
APPPATH = path to the application folder.
Its working...

if(isset($_FILES['image']) && $_FILES['image']['name'] != '')
{
$config['upload_path'] = './upload/image';
$config['allowed_types'] = 'jpeg|jpg|png';
$config['file_name'] = base64_encode("" . mt_rand());
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!$this->upload->do_upload('image'))
{
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('msg', 'We had an error trying. Unable upload image');
}
else
{
$image_data = $this->upload->data();
#unlink("./upload/image/".$_POST['prev_image']);
$testData['image'] = $image_data['file_name'];
}
}

$m_img_real= $_SERVER['DOCUMENT_ROOT'].'/images/shop/real_images/'.$data['settings']->shop_now;
$m_img_thumbs = $_SERVER['DOCUMENT_ROOT'].'/images/shop/thumbs/'.$data['settings']->shop_now;
if (file_exists($m_img_real) && file_exists($m_img_thumbs))
{
unlink($m_img_real);
unlink($m_img_thumbs);
}

Answer 5

View:
<input type="file" name="new_file" data-required="1" class="" />
<input type="hidden" name="old_file" value="echo your old file name"/>
<input type="submit" name="submit"/>
Controller:
function edit_image() {
if(isset($_FILES['new_file']['name']) && $_FILES['new_file']['name'] != '') {
move_uploaded_file($_FILES['new_file']['tmp_name'],'./public_html/banner/'.$_FILES['new_file']['name']);
$upload = $_FILES['new_file']['name'];
$name = $post['old_file'];
#unlink("./public_html/banner/".$name);
}
else {
$upload = $post['old_file'];
}
}

Answer 6

Try using delete_files('path') function offered by CI framework itself:

Answer 7

$image_data = $this->upload->data();
unlink($image_data['full_path']);
This line $this->upload->data() will return many information about uploaded file. You can print information and work accordingly.
