More clarification - Re: [PEAR] Can you serialize a Formbuilder object?

On the first creation of the $fb FormBuilder object, this HTML code is generated by echo print_r($fb); (Notice the array elements are QuickForm_header and QUickForm_hidden rather than __PHP_Incomplete_Class) ---begin snippet--- [_elements] => Array ( [0] => HTML_QuickForm_header Object ( [_text] => MY_TABLE [_label] => [_type] => header [_flagFrozen] => [_persistantFreeze] => [_attributes] => Array ( [name] => ) [_tabOffset] => 0 [_tab] => [_lineEnd] => [_comment] => ) [1] => HTML_QuickForm_hidden Object ( [_label] => [_type] => hidden [_flagFrozen] => [_persistantFreeze] => [_attributes] => Array ( [name] => SYSPROBE [type] => hidden [value] => ) [_tabOffset] => 0 [_tab] => [_lineEnd] => [_comment] => ) --end snippet--- After storing it in $_SESSION and retrieving, it looks like this, unless I require every single file in the HTML/QuickForm directory. > > > ---begin html source------ > [_elements] => Array > ( > [0] => __PHP_Incomplete_Class Object > ( > [__PHP_Incomplete_Class_Name] => > HTML_QuickForm_header > [_text] => MY_TABLE > [_label] => > [_type] => header > [_flagFrozen] => > [_persistantFreeze] => > [_attributes] => Array > ( > [name] => > ) > > [_tabOffset] => 0 > [_tab] => > [_lineEnd] => > > [_comment] => > ) > > [1] => __PHP_Incomplete_Class Object > ( > [__PHP_Incomplete_Class_Name] => > HTML_QuickForm_hidden > [_label] => > [_type] => hidden > [_flagFrozen] => > [_persistantFreeze] => > [_attributes] => Array > ( > [name] => SYSPROBE > [type] => hidden > [value] => > ) > > [_tabOffset] => 0 > [_tab] => > [_lineEnd] => > > [_comment] => > ) > > ---end HTML source------ > > > > If the solution is to simply require everything in that directory then that's fine.
