The password autocompletion in case of Moodle makes sense only on the login page, the form autocompletion in general is most probably useful only on the user signup page. This patch is compatible with html 5, unfortunately we have to ignore strict warnings in legacy xhtml 1.0 standard.

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