General help

Although it's not impossible, you don't normally store a file (of any kind) in a database. Certainly not in Moodle. There's a whole file system for this.

As this refers to a form, you probably want - https://docs.moodle.org/dev/Using_the_File_API_in_Moodle_forms

Although the following is useful as well - https://docs.moodle.org/dev/File_API

Note that the file is stored with an 'item id'. That's what you want to store in the database so you can reference the file. However, there is often a 'natural' id that you can use (e.g. the id number of a database record you will be creating anyway)

Hi Nilesh,

The code "print_r($fromform->uploadfile);" gives you the itemid of the stored file. Their are many way  available both in moodle and php to print that image on page. You just need to pass correct parameter like file context, itemid, filepath, filename. All these information are available in prefix_files. You can find that file in moodle and move that file in temporary location and then print it by using moodle core function or simple php functions.
To store files you can use Moodle filepicker or Filemanager  :-

                        $filemanageroptions = array();
			$filemanageroptions['accepted_types'] = '*.pdf, *.jpg';
			$filemanageroptions['maxbytes']       = $CFG->maxbytes;
			$filemanageroptions['subdirs']        = 0;
			$filemanageroptions['maxfiles']       = 1;

			$storeFile->addElement('filemanager', 'attachments', get_string('file_upload', 'local_plugin'), null, $filemanageroptions);
