Re: Is their something like $classname::$tablename ?

Thanks Jochem, I now solved the problem with your help, the following way: In the parent-class I define: static function getTableName($classname) { if (defined("$classname::TABLE_NAME")) { return(constant("$classname::TABLE_NAME")); } else { throw new Exception("No TABLE_NAME for ".$classname." defined!"); } } And in each child-class I define, the const TABLE_NAME. Now I have two more problems: - I have to pass the Classname as a parameter to all my static functions: for Example: echo testTable::toHtml_table_heading($dbConnect, "testTable"); - I need a similar thing for an Array $fields, which contains the field descriptions of the class: static function toHtml_table_heading($dbConnect, $classname) { $result = "\n\t<tr>"; if (!isset("$classname::$fields")) { $classname->intializeClass($dbConnect, $classname); } ...

Hi, I've got one function getTableName() which returns the Database-Table with the data of a class (see below). As you can see it always calls the static $tablename of the subclass described by $this->classname.

I solved this problem by doing the following: abstract class DBTable { // we can't define abstract consts. // but this must be defined in your subclass // const TABLE_NAME = 'xxxxx'; // define this func in your subclasses abstract function getTableName(); } class C1 extends DBTable { function getTableName() { return self::TABLE_NAME; } } it seems like a crap way of doing it but its very flexible and easy to understand (it just doesn't have that certain 'je ne c'est quoi') - none the less it was born out of a need for major flexibility (for pretty much similar reasons to you - namely generic data objects), anyway it gives you many ways to skin the cat (get the tablename): <? $c = new C1; echo $c->getTableName(); echo C1::getTableName(); echo C1::TABLE_NAME; $a = 'C1'; if (defined("$a::TABLE_NAME")) { echo constant("$a::TABLE_NAME"); } if someone has a better way, bring it on :-) I'd love to be able to improve my own code. You may also want to look at the possibility of using class names that are always indentical to the table names - I tried that but I didn't like it.

Thankyou, André Here the function: function getTableName() { if ($this->classname == "class1") { return class1::$tablename; } elseif ($this->classname == "class2") { return class2::$tablename; } elseif ($this->classname == "class3") { return class3::$tablename; }... ... }else { throw new Exception($this->classname." not found!"); } }
