Preventing form submission when there is no attachment

[Ankur Bawiskar]

@lhieanne 

this is for catalog item?

is this for portal only?

Should the attachment be mandatory based on some variable?

If my response helped please mark it correct and close the thread so that it benefits future readers.

this is for catalog item in portal, then attachment should be mandatory when the selected application has attachment required = true in the table.

Hi @lhieanne ,

try below code.

function onSubmit() {
    var appSysId = g_form.getValue('adt_application_name');

    // Check if the application Sys ID is provided
    if (!appSysId) {
        g_form.addErrorMessage('Application Sys ID is required.');
        return false; // Prevent form submission
    }

    // Use GlideAjax to determine if attachments are required
    var ga = new GlideAjax('global.AttachmentRequiredHelper');
    ga.addParam('sysparm_name', 'getAttachmentRequired');
    ga.addParam('appSysId', appSysId);
    ga.getXMLAnswer(function(response) {
        if (!response) {
            alert('Error: No response from GlideAjax for attachment requirement check.');
            return false; // Prevent form submission
        }

        var attachmentRequired = response;
        if (attachmentRequired) {
            checkAttachments(g_form.getUniqueValue());
        } else {
            g_form.submit(); // Submit the form if attachments are not required
        }
    });

    // Always prevent form submission initially
    return false;

    // Function to check for attachments
    function checkAttachments(tableSysId) {
        var attachmentGa = new GlideAjax('global.AttachmentRequiredHelper');
        attachmentGa.addParam('sysparm_name', 'hasAttachments');
        attachmentGa.addParam('tableSysId', tableSysId);
        attachmentGa.getXMLAnswer(function(response) {
            if (!response) {
                alert('Error: No response from GlideAjax for attachment check.');
                return false; // Prevent form submission
            }

            var hasAttachments = response;
            if (hasAttachments) {
                g_form.submit(); // Submit the form if attachments are found
            } else {
                g_form.addErrorMessage('Attachment is required because "Attachment Required" is set to True for the selected application.');
            }
        });
    }
}
