Hey all, I'm having a few difficulties checking for attachments, checking the attachments name for special characters, and checking for multiple instances of file extensions. We need to check for this due a process we have that errors out if the file name has these things. Here is the code I've put together but can't seem to get any of it working right.
Running this from a catalog client script so that this should work from the portal view.
function onSubmit() {
var cat_id = g_form.getValue('sysparm_item_guid');
var gr = new GlideRecord("sys_attachment");
gr.addQuery("table_name", "sc_cart_item");
gr.addQuery("table_sys_id", cat_id);
gr.query();
if (!gr.next()) {
alert("You must add an attachment before submitting this request.");
return false;
}
var fileName = gr.getValue("file_name");
var specialChars = /^[a-zA-Z0-9]+$/;
if (specialChars.test(fileName)) {
alert("The file name contains special characters, please remove them and try again.");
return false;
}
var fileExt = fileName.substr(fileName.lastIndexOf(".") + 1);
var multipleExts = new RegExp(fileExt + "{2,}");
if (multipleExts.test(fileName)) {
alert("The file name contains multiple instances of the file extension, please remove them and try again.");
return false;
}
}
Right now the code throws a false on "You must add an attachment", regardless if there is an attachment. However I did have this portion working previously with different code but with the rest of the code it failed to check for the special characters and failed to check for the multiple instances of the file extension.
Anyone have any ideas on how I can go about this? Thanks in advance.
