[RESOLVED] Warning: Missing argument 4

[Horizon88]

This is really weird. I added a new parameter to my function to allow customizable indentation strings, and it broke it. :\

Here's the original function declaration:

function displayTree($parentID, $level, $tableName) {
...
}

Which works when I call it like so:

displayTree('', 0, 'pages');

Now, I updated the function to this:

function displayTree($parentID, $level, $tableName, $indentStr) {
...
}

and call it like this:

displayTree('', 0, 'pages', ' -- ');

And now it spits out an error:

Warning: Missing argument 4 for displaytree() in /path/ on line 86

I've tried re-ordering the parameters, changing the inputs, using double-quotes instead of single-quotes, and I just don't know what's doing it. Any ideas?

Problem solved.

Didn't update the parameters passed in the recursive second call. D'oh!
