To validate a Date field inside a Multi-Row Variable Set (MRVS) in a catalog item, you’ll need to use Catalog Client Scripts in combination with g_form.getControl() and a loop over the MRVS rows.
✅ 1. Use a Catalog Client Script (onLoad or onSubmit)
Here’s how you can loop through rows and validate a date field:
function onSubmit() {
var isValid = true;
var rows = g_form.getMultipleRows(); // all rows of MRVS
for (var i = 0; i < rows.length; i++) {
var dateVal = rows[i].variable_name; // replace with your date field's variable name
if (new Date(dateVal) < new Date()) {
isValid = false;
g_form.showFieldMsg('multi_row_variable_set', 'Date must be in the future', 'error');
break;
}
}
return isValid;
}
✅ 2.
Alternative: Use g_form.getValue() on MRVS Scoped Name
If the MRVS is named my_mrvs, and your date variable is my_date, access like:
var allRows = g_form.getValue('my_mrvs');…but this returns a stringified object. You’ll need to parse the value if accessed this way — not recommended unless you’re comfortable with serialized MRVS data.
🔒 Important:
MRVS fields are tricky — client scripts must be global (Type: Catalog Client Script) and set for “Applies on Requested Item”.
Server-side validation can also be done via Catalog Item Validator Script for extra enforcement.
