Within the structure of my project, there is a directory labeled secure located in the root. The overall package of the project appears as follows:
application
secure
system
...........
Images are being uploaded inside the secure folder upon form submission using the following code snippets:
$config1['upload_path'] = './secure/';
$ext = end(explode(".", $_FILES['thumb_image']['name']));
$config1['file_name'] = time().$_FILES['thumb_image']['name'];
$config1['allowed_types'] = 'jpg|png|jpeg|gif|bmp|jpe|tiff|tif';
$this->load->library('upload', $config1);
$this->upload->initialize($config1);
$this->upload->do_upload('thumb_image');
The upload functionality works correctly. However, when attempting to edit details through another form and replacing the current image file with a new one, I aim to unlink the existing file before uploading the new one.
To achieve this, I have implemented the following code:
unlink(base_url("secure/".$data['row']->videothumbnail));
I have also tried:
unlink('/secure/'.$data['row']->videothumbnail);
where $data['row']->videothumbnail) represents the current image file stored in the database. While the new file uploads successfully, the old file remains intact and does not get unlinked. I have ensured that the permissions for the secure folder are set to 777. Could it be possible that the issue lies with the read-only permission set on the uploaded images preventing them from being unlinked?
If anyone could offer guidance on how to resolve this issue, I would greatly appreciate it.
Thank you in advance.
