I have many controllers with functions like
function search($person) {
if empty($person) {
redirect('...');
}
else {
.........
}
}
I wasn't getting 开发者_如何学编程Undefined variable errors before, but now i do (if i go to .../search/) without passing a $person. I found i can fix this by doing function search($person = null)
but i was wondering if there is a "better" way. I am also curious why i wasn't getting errors before (on localhost) but am now.. (on godaddy).
THANKS!!!
I wouldn't provide a default value for the argument in this case, function search($person)
is how the function should be declared if $person
is indeed a required argument. You want this to throw a warning so you can quickly see what's wrong during development.
In production, you simply switch off error reporting/error display.
