Question

我在moodle中创建一个表单。我需要在enctype属性中multipart/form-data来处理文件。但我不知道应该在哪里设置属性。以及如何设置它。

Answer 1

使用Forms API查看Files API以上传文件。

http://docs.moodle.org/dev/Using_the_File_API_in_Moodle_forms

更新：Haven未对此进行测试，但它是我现有代码的缩减版本

在你的edit.php文件中有这样的内容：

require_once(dirname(__FILE__) . '/edit_form.php');

$id = optional_param('id', null, PARAM_INT);

if ($id) {
    // Existing record
    $record = $DB->get_record('mytablename');
} else {
    // New record
    $record = new stdClass();
    $record->id = null;
    $record->myfield = '';
    ...
}

// Prepare the files.
$fileoptions = array(
    'maxbytes' => get_max_upload_file_size(),
    'maxfiles' => '1', // Change this to how many files can be uploaded.
    'subdirs' => 0, // No sub directories.
    'context' => $context
);
$record = file_prepare_standard_filemanager($record, 'myfiles',
        $fileoptions, $context, 'mypluginname', 'myfiles', $record->id);

$mform = new edit_form(null, array('fileoptions' => $fileoptions));

if ($formdata = $mform->get_data()) {
    // Form has been submitted.
    if (empty($formdata->id)) {
        // New record so create it.
        $recordid = $DB->insert_record('mytablename', $formdata);
        $record = $DB->get_record('mytablename', array('id' => $recordid));
    } else {
        // Update it.
        $DB->update_record('mytablename', $formdata);
        $record = $DB->get_record('mytablename', array('id' => $id));
    }
    // Save the files.
    $formdata = file_postupdate_standard_filemanager($formdata, 'myfiles',
            $fileoptions, $context, 'mypluginname', 'myfiles', $record->id);

} else {
    // Display the form.
    $mform->set_data($record);
    $mform->display();
}

在你的edit_form.php中有这样的东西

defined('MOODLE_INTERNAL') || die;

require_once($CFG->libdir . '/formslib.php');

class edit_form extends moodleform {

    public function definition() {

        $fileoptions = $this->_customdata['fileoptions'];

        $mform =& $this->_form;

        $mform->addElement('hidden', 'id');
        $mform->setType('id', PARAM_INT);

        ...

        $mform->addElement('filemanager', 'myfiles_filemanager',
                get_string('myfiles', 'mypluginname'), null, $fileoptions);

        $this->add_action_buttons(false, get_string('submit'));
    }

}

设置＆＃39; enctype＆＃39; moodle形式的表单属性？
