/**
|
|
|
18 |
* formslib.php - library of classes for creating forms in Moodle, based on PEAR QuickForms.
|
|
|
19 |
*
|
|
|
20 |
* To use formslib then you will want to create a new file purpose_form.php eg. edit_form.php
|
|
|
21 |
* and you want to name your class something like {modulename}_{purpose}_form. Your class will
|
|
|
22 |
* extend moodleform overriding abstract classes definition and optionally defintion_after_data
|
|
|
23 |
* and validation.
|
|
|
24 |
*
|
|
|
25 |
* See examples of use of this library in course/edit.php and course/edit_form.php
|
|
|
26 |
*
|
|
|
27 |
* A few notes :
|
|
|
28 |
* form definition is used for both printing of form and processing and should be the same
|
|
|
29 |
* for both or you may lose some submitted data which won't be let through.
|
|
|
30 |
* you should be using setType for every form element except select, radio or checkbox
|
|
|
31 |
* elements, these elements clean themselves.
