Question

I always do POST’s check validation, sometime its get too messy and long. What is the best way to keep it shorter and tidy?

Example:

if (isset($_POST['albumName']) && trim($_POST['albumName']) != "" && isset($_POST['slugName']) && $_POST['slugName'] != "" && is_numeric($_POST['PhotoCatID'])) {
  //All good
}

Answer 1

The standard Filter extension may have what you’re looking for, filter_input in particular:

$albumName = filter_input(INPUT_POST, 'albumName', FILTER_SANITIZE_STRIPPED);
$slugNamed = filter_input(INPUT_POST, 'slugName', FILTER_SANITIZE_STRIPPED);
$PhotoCatId = filter_input(INPUT_POST, 'PhotoCatId', FILTER_SANITIZE_NUMBER_INT);

(I personally ended up writing wrappers named filter_get, filter_post and filter_request just to make the lines a bit shorter…)
