How to upload an image from custom portal widget and show that image in the ticket created?

[manmathpanda]

Dear Developers,

I am new to Service Portal and working on a custom portal widget where no record producer created instead all code are written in html for all fields of the form. like below

I have simply created 

<div class="row">
<label>Select a file: <input type="file" name="myFile"><br><br>

</div>

As i don't have idea how to create this, some code will helpful to me to achieve this?

Please help.

i want to create an attachment to upload passport images or files in the form and after submitting the form it should show in ticket as well.

Regards,

Manmath

ata._attachmentTable = "sc_req_item";//here put your table
	data.recordID = "46d91e8bdb800010feeb47823996190d";// this sys_id is of my instance, put your record or req sys_id so that it will be seen in REQ as well

instead of fixed data.recordID can we get dynamic record which is getting created, attachment should attach to it
