Undefined class constant - HELP

[ppowell]

class NicknameVerifier {

 function NicknameVerifier() {}

 function isValid() {
  if ($fileID) {
     $content = fread($fileID, HTMLRetriever::MAX_URL_SIZE);
     fclose($fileID);
     if ($content) $this->setErrorArray(array('nickname' => $content));	// DUP NICKNAME FOUND
     return false;
    }
   }
  }

}

Also consider:

class HTMLRetriever {

 var $MAX_URL_SIZE = 100000;

}

Upon the line:

$content = fread($fileID, HTMLRetriever::MAX_URL_SIZE);

I get the following error:

Fatal error: Undefined class constant 'MAX_URL_SIZE' in /wwwroot/mycgiserver.com/members/includes/chat_classes.php on line 230

I am using PHP version 5 at www.myjavaserver.com and I am completely at a loss as to what is going on. Both classes reside in chat_classes.php equally. Why am I getting an "undefined class constant" error, it's right there?!

Thanx

First, you haven't created an instance of class HTMLRetriever, also the :: operator is used for calling methods of a child's parent class.

include_once("html_retriever.php");

class NicknameVerifier { 
 function NicknameVerifier() {} 

 function isValid() { 
  if ($fileID) { 
     $html = new HTMLRetriever();
     $content = fread($fileID, $html->$MAX_URL_SIZE); 
     fclose($fileID); 
     if ($content) $this->setErrorArray(array('nickname' => $content));    // DUP NICKNAME FOUND 
     return false; 
    } 
   } 
  } 
}

Don't have to create an instance, since I now in PHP version 5 can make the variables static:

class HTMLRetriever {
 static $MAX_URL_SIZE = 100000;

 function HTMLRetriever() {}

}

class NicknameVerifier {

 static $MIN_NICKNAME_LENGTH = 2;

 function NicknameVerifier() {}

 function isValid() {
  if ($nickname < NicknameVerifier::$MIN_NICKNAME_LENGTH) {}
  print_r(HTMLRetriever::$MAX_URL_SIZE);
 }

}

It's not a "backwards compatible" solution, but it's a seriously cool OO way to go!

Or, since you're using PHP5...

const MAX_URL_SIZE = 100000;

OK, stand corrected 🙂

Morning. no caffeine, brain slow.

God, just realised how little I read of your first post. Sorry 🙂
