Access GET, POST or COOKIE input variables and more ($input API variable as a function)

  • Default behavior with no arguments is to return the $input API variable.
  • If given just a $type argument (like “get” or “post”), it will return a WireInputData object for that type.
  • If given a $type and $key arguments, it will return the value, or null if not present.
  • If $sanitizer argument given, the returned value will also be run through the given sanitizer.
  • If the $sanitizer argument is an array, the returned input value must be within the given list, or null if not (3.0.125+).
  • If $fallback argument given, it will return the fallback value if input value was not present or not valid (3.0.125+).
  • See the WireInput::get() method for all options.

Example

// Can be used the same way as the $input API variable
// In examples below the “post” can also be “get” or “cookie”
$input = input(); // Returns $input API var (WireInput)
$post = input()->post(); // Returns $input->post (WireInputData instance)
$foo = input()->post('foo'); // Returns POST variable “foo”
$bar = input()->post('bar', 'text'); // Returns “bar” after text sanitizer (3.0.125+)
$s = input()->post('s', ['foo', 'bar', 'baz']); // POST var “s” must match given list (3.0.125+)

// You can also move the arguments all to the function call if you prefer:
$s = input('get', 'sort'); // Returns GET var “sort”
$s = input('get', 'sort', 'fieldName'); // Returns “sort” after “fieldName” sanitizer
$s = input('get', 'sort', ['title', 'created']); // Require sort to be one in given array (3.0.125+)
$s = input('get', 'sort', ['title', 'created'], 'title'); // Same as above, fallback to 'title' (3.0.125+)

Usage

// basic usage
$wireInput = input();

// usage with all arguments
$wireInput = input(string $type = '', string $key = '', string $sanitizer = null, $fallback = null);

“To Drupal, or to ProcessWire? The million dollar choice. We decided to make an early switch to PW. And in retrospect, ProcessWire was probably the best decision we made. Thanks are due to ProcessWire and the amazing system and set of modules that are in place.” —Unni Krishnan, Founder of PigtailPundits
