多个文件上传Moodle 2中的命令行脚本

Question

我获得了moodle上传到moodle课程的命令行脚本，编码如下。

为课程添加多个资源（到课程的第一部分）。资源将命名为“文件A”，“文件B”等。对于每个资源，我们将上传多个文件，并根据文件名决定哪个文件位于哪里，例如。以“a”开头的文件将转到名为“Files A”的资源。

我一步一步做了什么：

• 获取文件资源上下文ID

• 获取文件存储（单件）

• 创建文件信息数据

• 上传文件

现在，在获取资源上下文ID时，我们必须确保选择正确的资源名称（例如“文件A”）并且该资源确实存在。因此，我们需要一个能够为我们做到这一点的功能，并创建所有需要的资源。

然后我们需要确保新创建的资源可见，可用，创建上下文，资源放在正确的课程部分等等。我们还可以检查模块是否已启用以及许多其他内容，但这对于此示例来说已经足够了。

在整个操作之后，我们将清理课程缓存，以便用户可以看到新的课程元素。

        // get context again, this time with all resources present

        $context = get_context_instance(CONTEXT_MODULE, $coursemodule->cmid);

        return $context;
    }


} // get_resource
} 

输入就像

/> php filename.php courseid "upload/file/path" 

example: 

/> php script.php 4 "E:\file\untitled-1.pdf"

但结果是错误

Error: Not exists or Not readable 

请帮助解决此问题。     可以修复吗

提前致谢。

我对您的代码进行了一些更改，因为我尝试过的moodle版本告诉我某些功能已被弃用。

我已经测试了下面的代码，可以使用文件或带资源的资源创建一个文件夹。

首先是资源我做了这个：

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

    $sql = "SELECT cm.id as cmid FROM {course_modules} cm, {resource} 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 resouce\n";

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

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

        $resource_data = new stdClass();
        $resource_data->course = $course->id;
        $resource_data->name = $resource_name;
        $resource_data->intro = '<p>'.$resource_name.'</p>';
        $resource_data->introformat = 1;
        $resource_data->tobemigrated = 0;
        $resource_data->legacyfiles = 0;
        $resource_data->display = 0;
        $resource_data->displayoptions = 'a:2:{s:12:"printheading";i:0;s:10:"printintro";i:1;}';
        $resource_data->revision = 1;
        $resource_data->completion = 1;
        $resource_data->showavailability = 1;
        $resource_data->timemodified = time();

        $resource_id = $DB->insert_record('resource', $resource_data);

        // add course module
        $cm = new stdClass();
        $cm->course = $courseid;
        $cm->module = $module->id; // should be retrieved from mdl_modules
        $cm->instance = $resource_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
        $context = get_resource($courseid, $resource_name);
        return $context;

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

        return $context;
    }
} // get_resource

对于文件夹我做了这个：

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

    $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

我如何称呼这个功能：

$resource = get_folder($course, 'Folder Script'); // for folders
//$resource = get_resource($course, 'Resource Script'); // for resources

$fs = get_file_storage();
$filename = 'Text1.txt';    

// Prepare file record object
$fileinfo = array(
      'contextid' => $resource->id, // ID of context
      'component' => 'mod_folder',     // usually = table name
      'filearea' => 'content',     // usually = table name
      'itemid' => 0,               // usually = ID of row in table
      'filepath' => '/',           // any path beginning and ending in /
      'filename' => $filename); // any filename
/*$fileinfo = array(
      'contextid' => $resource->id, // ID of context
      'component' => 'mod_resource',     // usually = table name
      'filearea' => 'content',     // usually = table name
      'itemid' => 0,               // usually = ID of row in table
      'filepath' => '/',           // any path beginning and ending in /
      'filename' => $filename); // any filename
*/

$path_upload = '/path/Text1.txt';   

$existingfile = $fs->file_exists($resource->id, 'mod_resource', 'content', 0, '/', $filename);

if ($existingfile) {
    //the file exists
} else {
    $fs->create_file_from_pathname($fileinfo, $path_upload);
    //file uploaded
}

请注意，这是一个快速测试。

我希望这能为你服务。
