18 | * formslib.php - library of classes for creating forms in Moodle, based on PEAR QuickForms. | |
da1320da | 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 : | |
78bfb562 | 28 | * form definition is used for both printing of form and processing and should be the same |
da1320da | 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. | |
32 | * | |
