在 Moodle 中以编程方式上传课程中的文件和文件夹

Question

我需要将文件和文件夹从 zip 文件上传到 Moodle 中的课程中，我一直在搜索并找到了如何上传文件的方法。我尝试上传，文件已正确上传到数据库和文件存储库中，但是当我进入课程时，这些文件没有显示在课程中。

下面的代码是我尝试的

$packer = get_file_packer('application/zip');
$files = $packer->extract_to_pathname($archivo_zip, $carpeta_unzip );

foreach($files as $path => $status){
    $fs = get_file_storage();                                   
    $context = context_course::instance($courseid);

    $filename = basename($path);
    $path_directory = "/" . str_replace($filename, "", $path);

    $author = $DB->get_record('user', array('id'=>$userid ), '*', MUST_EXIST);

    $file_record = new stdClass;
    $file_record->component = 'mod_folder';     //mod_resource  
    $file_record->contextid = $context->id;         
    $file_record->userid    = $userid ;                 
    $file_record->filearea  = 'content';            //draft, attachment
    $file_record->filename = $filename;             
    $file_record->filepath  = $path_directory;      
    $file_record->itemid    = 0;                
    $file_record->author    = fullname($author);
    $file_record->license   = $CFG->sitedefaultlicense;
    $file_record->source    = $filename;            
    //$file_record->timecreated    = time();            
    //$file_record->timemodified    = time();           

    $existingfile = $fs->file_exists($file_record->contextid, $file_record->component, $file_record->filearea,
    $file_record->itemid, $file_record->filepath, $file_record->filename);

    if ($existingfile) {
        //throw new file_exception('filenameexist');
    } else {
        $stored_file = $fs->create_file_from_pathname($file_record, $path_upload);
    }
}

我尝试通过网站手动上传文件，我注意到文件夹 ara 在另一个名为 mdl_folder 的表或名为 mdl_file 的表中创建，但我不知道该怎么做以编程方式创建文件夹并将其与文件相关联的最佳方法，然后很好地显示在网站上。

因此，如果有人知道如何做或有任何可能有用的示例或文档，那将会很有帮助。

提前致谢。

我找到了一个适合我的解决方案，我不知道它是否最合适，是否有人可以看看并告诉我它是否正确，或者可以做出哪些改变将不胜感激.

我找到的解决办法是：

• 创建或取回将包含文件的文件夹
• 上传文件

代码：

    $packer = get_file_packer('application/zip');
    $files = $packer->extract_to_pathname($archivo_zip, $carpeta_unzip );

    foreach($files as $path => $status){
        $fs = get_file_storage();    

        $folder = get_folder($courseid, 'Upload Test');   

        $filename = basename($path);
        $path_directory = "/" . str_replace($filename, "", $path);

        $author = $DB->get_record('user', array('id'=>$userid ), '*', MUST_EXIST);

        $file_record = new stdClass;
        $file_record->component = 'mod_folder';     //mod_resource  
        $file_record->contextid = $folder->id;         
        $file_record->userid    = $userid ;                 
        $file_record->filearea  = 'content';            //draft, attachment
        $file_record->filename = $filename;             
        $file_record->filepath  = $path_directory;      
        $file_record->itemid    = 0;                
        $file_record->author    = fullname($author);
        $file_record->license   = $CFG->sitedefaultlicense;
        $file_record->source    = $filename;            
        //$file_record->timecreated    = time();            
        //$file_record->timemodified    = time();           

        $existingfile = $fs->file_exists($file_record->contextid, $file_record->component, $file_record->filearea,
        $file_record->itemid, $file_record->filepath, $file_record->filename);

        if ($existingfile) {
            //throw new file_exception('filenameexist');
        } else {
            $stored_file = $fs->create_file_from_pathname($file_record, $path_upload);
        }
    }

创建或取回文件夹的功能是：

function get_folder($courseid, $resource_name) {
    global $DB, $CFG;

    //Comprobamos si la carpeta ya existe ya existe

    $sql = "SELECT cm.id as cmid FROM {course_modules} cm, {folder} res
        WHERE res.name = '" . $resource_name . "'
        AND cm.course = " . $courseid . "
        AND cm.instance = res.id";

    if (! $coursemodule = $DB->get_record_sql($sql)) {      
        require_once($CFG->dirroot.'/course/lib.php');

        echo "\tCreate new folder\n";

        $course = $DB->get_record('course', array('id' => $courseid), '*', MUST_EXIST);

        // get module id
        $module = $DB->get_record('modules', array('name' => 'folder'), '*', MUST_EXIST);

        // get course section
        /*course_create_sections_if_missing($course->id, 0);
        $modinfo = get_fast_modinfo($course->id);
        $cw = $modinfo->get_section_info(0);

        echo "section id: " . $cw->id;*/

        $sectionid = $DB->get_record('course_sections', array('course' => $course->id, 'name' => 'Recursos'), '*', MUST_EXIST);

        $folder_data = new stdClass();
        $folder_data->course = $course->id;
        $folder_data->name = $resource_name;            
        $folder_data->intro = '<p>'.$resource_name.'</p>';
        $folder_data->introformat = 1;
        $folder_data->revision = 1;
        $folder_data->timemodified = time();
        $folder_data->display = 0;
        $folder_data->showexpanded = 1;
        $folder_data->showdownloadfolder = 1;

        $folder_id = $DB->insert_record('folder', $folder_data);

        echo "folder id: " . $folder_id;

        // add course module
        $cm = new stdClass();
        $cm->course = $courseid;
        $cm->module = $module->id; // should be retrieved from mdl_modules
        $cm->instance = $folder_id; // from mdl_resource
        $cm->section = $sectionid->id; // from mdl_course_sections
        $cm->visible = 1;
        $cm->visibleold = 1;
        $cm->showavailability = 1;
        $cm->added = time();

        $cmid = $DB->insert_record('course_modules', $cm);

        // add module to course section so it'll be visible
        if ($DB->record_exists('course_sections', array('course' => $courseid, 'section' => 1))) {
            $sectionid = $DB->get_record('course_sections', array('course' => $courseid, 'section' => 1));

            // if sequence is not empty, add another course_module id
            if (!empty($sectionid->sequence)) {
                $sequence = $sectionid->sequence . ',' . $cmid;
            } else {
                // if sequence is empty, add course_module id
                $sequence = $cmid;
            }

            $course_section = new stdClass();
            $course_section->id = $sectionid->id;
            $course_section->course = $courseid;
            $course_section->section = 1;
            $course_section->sequence = $sequence;
            $csid = $DB->update_record('course_sections', $course_section);

        } else {

            $sequence = $cmid;

            $course_section = new stdClass();
            $course_section->course = $courseid;
            $course_section->section = 1;
            $course_section->sequence = $sequence;

            $csid = $DB->insert_record('course_sections', $course_section);
        }

        rebuild_course_cache($courseid, true);      

        // get context again, this time with all resources present
        $context = get_folder($courseid, $resource_name);
        return $context;

    } else {
        $context = context_module::instance($coursemodule->cmid); 

        return $context;
    }
} // get_folder
