Languages :: PHP :: Supressing Warnings
By: PHP newbee U.S.A.  Date: 06/03/2003 00:00:00  English  Points: 50 Status: Answered

Hi All!

If I define a function like so:
// Start of Code
function printviewform($var) {
// End of Code

Is there any way I can supress the warnings given if the argument $var isn't passed to it?

Any help is appreciated,

yes, of course. Make it (Ada-Like) an optional parameter by providing a default value

declare the function as :
function printviewform($var="") {

and that's all

PS. With your example above, would that not restrict any value being passed to $var, as it sets it to "" when the function is called?

Or am I being clueless again?

no
it's the default value, that's the one if no value is provided as an argument
if $var received a value by argument, fine. If no argument makes it through, $var will have it's default value as per the si gnature of the function.
This is 100% ADA
