Function Reference

wp_stream_filter_input()

Gets a specific external variable by name and optionally filters it.

This is a polyfill function intended to be used in place of PHP's filter_input() function, which can occasionally be unreliable. See issue #257 for more info.

Return

(mixed) Value of the requested variable on success, FALSE if the filter fails, or NULL if the $variable_name is not set.

Params

$type (int) One of INPUT_GET, INPUT_POST, INPUT_COOKIE, INPUT_SERVER, or INPUT_ENV.

$variable_name (string) Name of a variable to get.

$filter (int) The ID of the filter to apply. The Types of filters manual page lists the available filters.

$options (mixed) Associative array of options or bitwise disjunction of flags. If filter accepts options, flags can be provided in "flags" field of array.
