Form Gen.

Ein wahnsinns praktisches Teil wenn mal schnell ein Formular benötigt das auch noch gleich mit validiert werden soll.

Script:

<?php
class form_o_mat
{
var $id; //Form name (to identify if it was send)
var $action; //Where should this form post? (if nothing, it self)
var $caption; //Caption to show the user
var $target = "_self"; //What should the target be?
var $style; //If there is a css class for this form, put the name here
var $enctype; //Will automaticly be set to multipart/form-data if there is a form with a file obj.
var $hide = FALSE; //Shuld the form be hidden if there are no errors in the send data?

var $_error=""; //Intern error trigger
var $_error_msg=""; //Intern error message to be displayed
var $_data=""; //Intern usage for storing the form data
