getting sys_id of currently open catalog form

[Ubada Barmawar]

Hi Everyone,

I have a catalog item, and due to some organization standards I cannot use variable type 'attachment'. so I had to go ahead with form attachment. now that I want to clear the attachments based on some onchange conditions, Im not able to find a solution for that. I have referred THIS but it doesnt serve the purpose on service portal(it works only through 'try it' button).

is there any other way that I can access the 'sys_id' of currently open catalog form(when I attach an attachment, the sys_id of currently open form is pasted in sys_attachment table). using this sys_id I want to enhance user experience by deleting the attachment onchange of relevant fields.

I really appreciate any solution for this usecase,

thanks and regards,

Ubada Barmawar.

@Ubada Barmawar Attachments uploaded in the Service Portal are temporarily linked using a temporary ID (e.g., sysparm_item_guid) until the form is submitted. You can access this ID in your client script using:

var tempId = g_form.getParameter('sysparm_item_guid');

This tempId can be used to query the sys_attachment table to get attachments associated with the form before submission.

Example:

var ga = new GlideAjax('AttachmentHandler');

ga.addParam('sysparm_name', 'getAttachments');

ga.addParam('sysparm_temp_id', tempId);

ga.getXMLAnswer(function(response) {

    var attachments = JSON.parse(response);

    // Process attachments as needed

});

The Script Include (AttachmentHandler) could look like this:

var AttachmentHandler = Class.create();

AttachmentHandler.prototype = {

    initialize: function() {},

    getAttachments: function(tempId) {

        var result = [];

        var gr = new GlideRecord('sys_attachment');

        gr.addQuery('table_sys_id', tempId);

        gr.query();

        while (gr.next()) {

            result.push({

                sys_id: gr.getValue('sys_id'),

                file_name: gr.getValue('file_name')

            });

        }

        return JSON.stringify(result);

    },

    type: 'AttachmentHandler'

};

Once you have the list of attachments, you can delete them based on specific conditions using the GlideSysAttachment API in a GlideAjax call:

var ga = new GlideAjax('AttachmentHandler');

ga.addParam('sysparm_name', 'deleteAttachments');

ga.addParam('sysparm_temp_id', tempId);

ga.getXMLAnswer(function(response) {

    // Handle deletion respon

se

});

hope this will help you.

unfortunately, g_form.getParameter('sysparm_item_guid') doesnt seem to work on sp, but it does work in native UI. 

so..can we make it work somehow?
