Is_dir and Is_file inside foreach loop error. - wolfgang1983 - 03-09-2017
I am getting error in my foreach loop using
Array to string conversion error. On the line where is_dir and is_file.
Question: Where have I gone wrong? How to fix it?
Seems to be if any files in sub folder throws the error that's what causing error.
PHP Code:
foreach ($files as $image) {
if (is_dir($directory . $image)) {
$data['images'][] = array(
'name' => $image
);
} elseif (is_file($directory . $image)) {
$data['images'][] = array(
'name' => $image
);
}
}
Controller function
PHP Code:
public function index() {
$userdata = $this->user_model->getuser($this->user_model->getuserid());
if ($this->input->get('directory')) {
$directory = FCPATH . 'uploads/' . $userdata['upload_folder'] .'/'. $this->input->get('directory') .'/';
} else {
$directory = FCPATH . 'uploads/' . $userdata['upload_folder'] .'/';
}
$files = array();
$files = directory_map($directory, FALSE, TRUE);
$data['images'] = array();
foreach ($files as $image) {
if (is_dir($directory . $image)) {
$data['images'][] = array(
'name' => $image
);
} elseif (is_file($directory . $image)) {
$data['images'][] = array(
'name' => $image
);
}
}
$this->load->view('extension/filemanager', $data);
}

Perhaps your directory map is returning an array that is more complex than you have allowed for, so your $image is not a filename but an array of filenames. If you output the files array you generated with a var_dump what do you get?
