/** |
22 |
* This class is used to build and render the form. |
23 |
* It builds a form by creating FormElement objects |
24 |
* which have automatic validation. It leaves the |
25 |
* layout of the form up to the child class. It has |
26 |
* a mechanism in place to automagically show a |
27 |
* confirmation 'page' after the data has been submitted |
28 |
* and validated. It also provides a hook for any |
29 |
* 'back end' validation of data. Finally, it provides |
30 |
* a function for handling the action of the form, which |
31 |
* only gets call after ALL validation has passed. |
32 |
* |
33 |
* Functions: |
34 |
* |
35 |
* form_init_elements() - This function is used to |
36 |
* build the FormElement objects that will be used |
37 |
* by the form. This function is called EVERY time |
38 |
* the FormContent class is instantiated. After you |
39 |
* create the FormElement, you call the |
40 |
* FormContent::add_element() method, to add the |
41 |
* FormElement object to the form. You will then |
42 |
* call the 2 methods FormContent::element_label() and |
43 |
* FormContent::element_form() to get access to the |
44 |
* FormElement's label and form field respectively. |
45 |
* |
46 |
* form_init_data() - This is called only the first time |
47 |
* the form is encountered. It Allows you to populate |
48 |
* the FormElements with data from a DB for example. |
49 |
* You would use FormContent::set_element_value() or |
50 |
* FormContent::set_hidden_element_value() inside here. |
51 |
* |
52 |
* form() - This is the method that gets called to build |
53 |
* the layout for your form. Typically you use a table |
54 |
* and add the label in the first <td> and the form field |
55 |
* itself in the 2nd <td>. So there are 2 methods in |
56 |
* the FormContent object that allow u to get access to |
57 |
* the FormElements label, and form field. |
58 |
* FormContent::element_label() and |
59 |
* FormContent::element_form(). |
60 |
* |
61 |
* |
62 |
* form_backend_validation() - This method enables you to |
63 |
* do any "back end" validation of data. Such as, check |
64 |
* for a duplicate in the DB on a create/new form. This |
65 |
* is called after the FormElement's validation methods have |
66 |
* passed. |
67 |
* |
68 |
* form_action() - This method is called after ALL validation |
69 |
* was successfull, including each FormElement object's |
70 |
* validation methods, as well as the FormContent::form_backend_validation() |
71 |
* |
