Thank you very much for your contribution, now you can verify, the error is corrected

[imdewan]

the first error comes if we didn't upload error and the second one comes if we fill all inputs. Also the page doesn't create

[imdewan]

After adding a folder 'uploads' reduces some errors but the page is still not created

In the page table, parent is default '0', if not is selected you can use
// If parent not is integer or is empty
if (!is_int($parent) || empty($parent)) {
$parent = 0;
}

// Store in folder pages
$directory = 'pages/';
//Check if the directory already exists.
if (!is_dir($directory)) {
//Directory does not exist, so lets create it.
mkdir($directory, 0755, true);
}
// If you use and make php file
// $link_path = $directory . $link . ".php";
// If you use and make html file
$link_path = $directory . $link . ".html";
$myfile = fopen($link_path, "w") or die("Unable to open file!");
// For redirect php
// $txt = '';
// For redirect html
$txt = '<script>window.location.replace("../view.php?id=' . $last_id . '");</script>';
fwrite($myfile, $text);
fclose($myfile);
