why image unlink works when condition false
I have a form that can either add icon or a icontext. The problem is, that icon is unlinked from file path when I submit form without change.
if (isset($_POST['icontext'])) { // echo '<pre>';print_r($_POST['icontext']);exit;
if(file_exists(UPLOAD_PATH . 'images/highlights_icon/' . $this->view->highlights['highlighticon'] )) {
unlink(UPLOAD_PATH . 'images/highlights_icon/' . $this->view->highlights['highlighticon']);
//echo '<pre>';print_r($this->view->highlights['highlighticon']);exit;
}
}

maybe you want!empty($_POST['icontext'])instead of isset?icontextcould/will be set even if it's an empty string.

I think you want to check whether $_POST['icontext'] is empty or not, instead of checking whether it is_set or not, because it might be set even if it's only an empty string.
So change your code to
if (!empty($_POST['icontext'])) {
//...
}
