Accessing a function directly - El Forum - 10-22-2008

I have a function that passes an id to a destination page that pulls data from a table based on that id. Everything works fine when the URL contains a number at the end like post/1, but when I hit the function directly like post/ it gives errors saying "Message: Missing argument 1 for welcome::post()" .
Is there a way to make that URL redirect to another page?

Such a well written question...such a little thought put the problem...
Open your most basic PHP reference and find the section on User Defined functions. It will explain that when you demand that PHP expect a parameter as input...it will do exactly what you tell it too.
Simply change your method declaration from
Code:
function post($id)
{
}to...
Code:
function post( $id=NULL )
{
}you can either capture $id=NULL and redirect on that or change $id do a different default value and show a predefined default post.
