Application::setHidden

Set values for hidden inputs

Description

public void Application::setHidden( mixed $name, [ mixed $value = "" ] )
public void Application::unsetHidden( string $name )

setHidden() stores a value that the {{ hidden }} tag prints as <input type="hidden">. unsetHidden() removes one again.

Names and values are HTML-escaped (a value that is already escaped is not escaped twice). An array value is printed as one input per element, with names such as tags[0] and tags[1].

See also Hidden.

$value	string / array	""	Hidden value (ignored when $name is an array)
