Access GET, POST or COOKIE input variables and more ($input API variable as a function)
- Default behavior with no arguments is to return the
$inputAPI variable. - If given just a
$typeargument (like “get” or “post”), it will return aWireInputDataobject for that type. - If given a
$typeand$keyarguments, it will return the value, or null if not present. - If
$sanitizerargument given, the returned value will also be run through the given sanitizer. - If the
$sanitizerargument is an array, the returned input value must be within the given list, or null if not (3.0.125+). - If
$fallbackargument 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);Arguments
