This article describes how to change the maximum number of input variables allowed for PHP scripts by using the max_input_vars directive in a php.ini file.
PHP obtains input variables from HTML forms (through GET and POST requests), as well as from any cookies enabled on a page. By default, the maximum number of input variables allowed for PHP scripts is set to 1000. You can change this amount by setting the max_input_vars directive in a php.ini file.
To change the maximum number of input variables allowed, use a text editor to add the max_input_vars directive to your php.ini file. For example, to set the maximum number of input variables to 1500, add the following setting:
max_input_vars = 1500
