Attachment Mandtory for a catalog item

[nameisnani]

Hi Team ,

We have a catalog item called “AWS Support”. Inside it, there is a variable called “Type of Request”.
One of the options for this variable is “Create AWS AD Group”.

If the user selects this option and tries to submit the form without adding an attachment, the form should not be submitted. Instead, the system should show an error message asking the user to attach the required file.

function onSubmit() {

    var requestType = g_form.getValue('type_of_request'); 

    if (requestType == 'Create AWS AD Group') {

        var attachmentCount = g_form.getValue('attachments'); // this only works with attachment mandatory check in later versions

        // For safer check - use g_form.hasAttachments() if your instance supports

        if (!g_form.hasAttachments()) {

            alert("Attachment is mandatory when selecting 'Create AWS AD Group'. Please attach a file before submitting.");

            return false; // Prevent submission

        }

    }

    return true;

}

the script which i have written it is not working - what was the error .

Hi @nameisnani 

Kindly make changes as per the below code. It should work.

Client Script

function onSubmit() {
    var requestType = g_form.getValue('type_of_request');

    if (requestType == 'Create AWS AD Group') {

        var sysid = g_form.getValue('sysparm_item_guid');
        var ga = new GlideAjax('CheckAttachment');
        ga.addParam('sysparm_name', 'hasAttachment');
        ga.addParam('sysparm_sysid', sysid);
        ga.getXMLWait();

        var answer = ga.getAnswer();
        if (answer == 'false') {
            alert("Please attach something before submitting this request.");
            return false;
        }
    }
    return true; // Allow submission if attachment exist
}

Script Include

var CheckAttachment = Class.create();
CheckAttachment.prototype = Object.extendsObject(AbstractAjaxProcessor, {
 hasAttachment:function() {
       
        var sysId = this.getParameter('sysparm_sysid');
        var gr = new GlideRecord('sys_attachment');
        gr.addQuery('table_name', 'sc_cart_item');
        gr.addQuery('table_sys_id', sysId);
        gr.query();
        return gr.hasNext().toString(); // Returns 'true' or 'false'
    },
    type: 'CheckAttachment'
});
