Stop user from deleting a set file name not working - wolfgang1983 - 10-10-2015
I have a file in two locations called no_image.jpg When user try's to delete the image I would like to be able to stop the user from deleting just that image.
But for some reason the image still gets delete How can I make it stop deleting image if file is no_image.png
PHP Code:
public function delete() {
$json = array();
if (!$json) {
foreach ($this->input->post('path') as $path) {
$no_image_check = $this->config->item('image_path') . 'catalog/no_image.jpg';
$no_image_cache_check = $this->config->item('image_cache_path') . 'catalog/no_image.jpg';
if (isset($no_image_check)) {
$json['error'] = 'You cannot remove this image';
}
if (isset($no_image_cache_check)) {
$json['error'] = 'You cannot remove this image';
}
if (is_dir($this->config->item('image_path') . $path)) {
rmdir($this->config->item('image_path') . $path);
rmdir($this->config->item('image_cache_path') . $path);
} elseif (is_file($this->config->item('image_path') . $path)) {
unlink($this->config->item('image_path') . $path);
unlink($this->config->item('image_cache_path') . $path);
}
}
$json['success'] = 'Your Selected File Has Been Removed!';
}
$this->output->set_content_type('Content-Type: application/json');
$this->output->set_output(json_encode($json));
}
Any examples on how to solve it would be great.

It looks like your "validation" is just checking if the variable $no_image_check is set, which it is on the previous line.
What you want to do is check if the actual file exists:

I have check boxes below each image though and user needs to have that check box checked before delete but need to make sure does not delete the no_image.jpg.
I am also not sure if I have my json message in correct places.
PHP Code:
public function delete() {
$json = array();
if (!$json) {
foreach ($this->input->post('path') as $path) {
$no_image_check = $this->config->item('image_path') . 'catalog/no_image.jpg';
if (isset($no_image_check)) {
$json['error'] = 'You canot remove this image';
} else {
if (is_dir($this->config->item('image_path') . $path)) {
if (file_exists($this->config->item('image_path') . $path)) {
delete_files($this->config->item('image_path') . $path);
delete_files($this->config->item('image_cache_path') . $path);
}
continue;
rmdir($this->config->item('image_path') . $path);
rmdir($this->config->item('image_cache_path') . $path);
$json['success'] = 'Your Selected Folder Has Been Removed!';
} elseif (is_file($this->config->item('image_path') . $path)) {
delete_files($this->config->item('image_path') . $path);
delete_files($this->config->item('image_cache_path') . $path);
$json['success'] = 'Your Selected File Has Been Removed!';
}
}
}
}
$this->output->set_content_type('Content-Type: application/json');
$this->output->set_output(json_encode($json));
}

After some more thinking about it I have got it all most working now.
In my foreach loop I have done a check like below.
if ($this->config->item('image_path') . $path == $no_image_check) {
PHP Code:
public function delete() {
$json = array();
if (!$json) {
$no_image_check = $this->config->item('image_path') . 'catalog/no_image.jpg';
foreach ($this->input->post('path') as $path) {
if ($this->config->item('image_path') . $path == $no_image_check) {
$json['error'] = 'Your Selected File Can\'t be removed!';
} else {
if (is_dir($this->config->item('image_path') . $path)) {
rmdir($this->config->item('image_path') . $path);
rmdir($this->config->item('image_cache_path') . $path);
$json['success'] = 'Your Selected Folder Has Been Removed!';
} elseif (is_file($this->config->item('image_path') . $path)) {
unlink($this->config->item('image_path') . $path);
unlink($this->config->item('image_cache_path') . $path);
$json['success'] = 'Your Selected File Has Been Removed!';
}
}
}
}
$this->output->set_content_type('Content-Type: application/json');
$this->output->set_output(json_encode($json));
}
