    Remapping Function Calls

    + +

    As noted above, the second segment of the URI typically determines which function in the controller gets called. +Code Igniter permits you to override this behavior through the use of the _remap() function:

    + +function _remap()
    +{
    +    // Some code here...
    +}     + +

    Important:  If your controller contains a function named _remap(), it will always +get called regardless of what your URI contains. It overrides the normal behavior in which the URI determines which function is called, +allowing you to define your own function routing rules.

    + +

    The overriden function call (typically the second segment of the URI) will be passed as a parameter the _remap() function:

    + +function _remap($method)
    +{
    +    if ($method == 'some_method')
    +    {
    +        $this->$method();
    +    }
    +    else
    +    {
    +        $this->default_method();
    +    }
    +}     + + + +

    Private Functions

    In some cases you may want certain functions hidden from public access. To make a function private, simply add an underscore as the name prefix and it will not be served via a URL request. For example, if you were to have a function like this:
