wie man Dateien beim Bearbeiten eines Dateimanagers in moodle

Question

Ich bin gerade dabei, ein Praktikum zu machen, und ich habe versucht, ein Aktivitätsmodul zur Wiedergabe von Playlist, von Video von einem Dateimanager gegeben. Es ist mir gelungen, das Video an die Datenbank zu senden, aber wenn ich mein Modul bearbeiten möchte, zeigt es keine Dateien im Dateimanager an.

las ich die moodle Dokumentation über file API und ich beschlossen, den folgenden Code (Load vorhandenen Dateien in Entwurf Bereich) verwenden

:

if (empty($entry->id)) { 
$entry = new stdClass; 
$entry->id = null; 
} 

$draftitemid = file_get_submitted_draft_itemid('attachments'); 
file_prepare_draft_area($draftitemid, $context->id, 'mod_glossary','attachment', $entry->id,array('subdirs' => 0, 'maxbytes' => $maxbytes, 'maxfiles' => 50)); 
$entry->attachments = $draftitemid; 
$mform->set_data($entry); 

Also habe ich die folgenden Zeilen in meinem mod_form.php :

$filemanager_options = array(); 
    $filemanager_options['accepted_types'] = '*'; 
    $filemanager_options['maxbytes'] = 0; 
    $filemanager_options['maxfiles'] = -1; 
    $filemanager_options['mainfile'] = true; 

     $mform->addElement('filemanager', 'files', get_string('selectfiles'), null, $filemanager_options); 



if (empty($entry->id)) { 
    $entry = new stdClass; 
    $entry->id = null; 
} 

$draftitemid = file_get_submitted_draft_itemid('mymanager'); 


file_prepare_draft_area($draftitemid, $this->context->id, 'mod_playlist', 'content', 0, 
         array('subdirs'=>true)); 

$entry->attachments = $draftitemid; 

$mform->set_data($entry); 

das Problem ist, dass der Datei-Manager noch leer ist, und die Zeile "$ mform-> set_data ($ entry)," macht die Seite (leer) zum Absturz bringen.

Hier ist eine Vorlage zum Hochladen von Dateien.

In local/myplugin/upload.php

require_once(dirname(dirname(dirname(__FILE__))) . '/config.php'); 
require_once(dirname(__FILE__) . '/upload_form.php'); 

require_login(); 

$context = context_system::instance(); 

require_capability('local/myplugin:upload', $context); 

$pageurl = new moodle_url('/local/myplugin/upload.php'); 
$heading = get_string('myupload', 'local_myplugin'); 
$PAGE->set_context($context); 
$PAGE->set_heading(format_string($heading)); 
$PAGE->set_title(format_string($heading)); 
$PAGE->set_url('/local/myplugin/upload.php'); 

echo $OUTPUT->header(); 
echo $OUTPUT->heading($heading); 

$fileoptions = array(
     'maxbytes' => 0, 
     'maxfiles' => '1', 
     'subdirs' => 0, 
     'context' => context_system::instance() 
); 

$data = new stdClass(); 

$data = file_prepare_standard_filemanager($data, 'myfiles', 
     $fileoptions, context_system::instance(), 'local_myplugin', 'myfiles', 0); // 0 is the item id. 

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

if ($formdata = $mform->get_data()) { 
    // Save the file. 
    $data = file_postupdate_standard_filemanager($data, 'myfiles', 
      $fileoptions, context_system::instance(), 'local_myplugin', 'myfiles', 0); 
} else { 
    // Display the form. 
    $mform->set_data($data); 
    $mform->display(); 
} 

echo $OUTPUT->footer(); 

dann in local/myplugin/upload_form.php

defined('MOODLE_INTERNAL') || die; 

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

class upload_form extends moodleform { 

    public function definition() { 
     $mform =& $this->_form; 

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

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

     $this->add_action_buttons(false, get_string('save', 'local_myplugin')); 

    } 
} 

Sie müssen auch diese in /local/myplugin/lib.php

function local_myplugin_pluginfile($course, $cm, $context, $filearea, $args, $forcedownload, array $options = array()) { 

    if ($context->contextlevel != CONTEXT_SYSTEM) { 
     send_file_not_found(); 
    } 

    $fs = get_file_storage(); 
    $file = $fs->get_file($context->id, 'local_myplugin', $filearea, $args[0], '/', $args[1]); 

    send_stored_file($file); 
}
