Development:Using the File API: Difference between revisions

Revision as of 05:34, 2 February 2009

Template:Moodle 2.0 The file API is for managing all the files stored by Moodle. If you are interested in how the file API works internally, see Development:File_API. The page is just about what you need to know to use the file API. Related is the Development:Repository API, which lets users get files into Moodle.

Overview of how it works

File areas

Serving files to users

Getting files from the user

Getting a file from a Moodle form

Getting a file with content from the HTML editor

Giving a file to the user

Moving files around

For example, if you have just built a file at the path

$from_zip_file =
$CFG->dataroot."/temp/backup/".$preferences->backup_unique_code."/".$preferences->backup_name;

And you want to move it into the course_backup file area, do

$context = get_context_instance(CONTEXT_COURSE, $preferences->backup_course);
$fs = get_file_storage();
$file_record = array('contextid'=>$context->id, 'filearea'=>'course_backup',
        'itemid'=>0, 'filepath'=>'/', 'filename'=>$preferences->backup_name,
        'timecreated'=>time(), 'timemodified'=>time());
$fs->create_file_from_pathname($file_record, $from_zip_file);
