Set a Minimum Order Quantity

Gravity Forms provides the ability to set a minimum per field when using a separate Quantity field but what about a minimum quantity for the entire order? This snippet can help!

Do I need to configure this snippet to work with my form?

Yes! This snippet has four bits to customize.

1. Update the 86 in the filter name gform_validation_86 to the ID of your own form.
2. Update the $min_qty variable to the minimum quantity your form should require.
3. Update the $min_qty_message variable to the validation message which should be displayed if the minimum quantity is not met. Use %1$d to populate the minimum number of tickets require. Use %2$d to populate the number of tickets the user must add to their order to meet the minimum. The actual values will be populated when the form is validated.

4. If you wish to limit the minimum quantity requirement to a specific set of fields, enter the IDs of these fields in the $min_qty_fields = array(); array like so: $min_qty_fields = array(3, 5);. Otherwise, simply leave this variable as is.
