Can user parameters be arbitrary?

Question

PHP

Everything is on one page. It is necessary to somehow enter the value from input into a variable without reloading. In theory.

<input type='text' name='Shp_name' value='Сюда вводим имя'>

$name = "Введенное имя в input попадает сюда";

$crc  = md5("$mrh_login::$inv_id:$mrh_pass1:Shp_name=$name");

Answer 1

If I understand correctly, then you need to pass the value from the form to the script without reloading the page. In this case, google towards AJAX. jQuery.ajax() or jQuery.post() to be specific.
