定制moodle注册表单

Question

I need to add attachment input to moodle sign up form
This file input is not supported by moodle through the standard user profile fields.

So I tried to add it manually:
I added:

$mform->addElement('file', 'attach', "Attach", null,array( 'accepted_types' => 'pdf'));
$mform->setType('attach', PARAM_RAW);
$mform->addRule('attach', 'Missing File Attachment', 'required', null, 'client');

But where should I tell Moodle to insert that value into the database?

Answer 1

You should probably first add a custom user profile field, as described here. Here you should override the function profile_save_data($usernew) to tell the system where you want to save your file.
If you want to learn how to get the file from the form and save it you can go here. In particular, you could use the filepicker form element, which replaces the old file element, with

$mform->addElement('filepicker', 'userfile', get_string('file'), null,
                   array('maxbytes' => $maxbytes, 'accepted_types' => 'pdf'));

Get the file content and file name as well as store it with:

$content = $mform->get_file_content('userfile');
$name = $mform->get_new_filename('userfile');
$success = $mform->save_file('userfile', $fullpath, $override);

where $fullpath is a path in the file sytem (such as the moodledata folder) and $override is a boolean meaning "override file if exists".
DISCLAIMER: I did not try this solution myself.
