unexpected T_VARIABLE error

[Kestrad]

Hey all! I'm getting an unexpected T_VARIABLE with the following function:

 

function getHighestParentName($id = $this->cid){

    $cat = mysql_fetch_assoc(fsquery('getParentCategories', $id));

    if ($cat['pid']!=0){getHighestParentName($cat['id']);}

    return $cat['name'];

}

 

fsquery is a function defined in another file, which I know is correctly defined and correctly referenced. pid, id, and name are column names in a mysql table. Can someone please help me find what's wrong? Thanks!

Can you tell us which specific line is throwing the error?

[rajivgonsalves]

you cannot do this $id = $this->cid, assign the default as another variable it should be something like $id = ''

Sorry, I don't quite understand--do you mean that I can't define $id as another variable that already exists?

could yo not just do this:

 

<?php
function getHighestParentName (){
     $cat = mysql_fetch_assoc(fsquery('getParentCategories', $this->cid));
     if ($cat['pid']!=0){getHighestParentName($cat['id']);}
     return $cat['name'];
}
?>

If the function doesn't take an argument, doesn't that mean I can't pass it one?

[mrMarcus]

did you try it?

 

seems you may be wandering into unknown territories with OOP here.

Yep. I'm not getting the error anymore! Thanks for your help!
