Forms Date Constraints

Forms
Updated September 24, 2024
asked on September 20, 2024

Hello, I have a Laserfiche form which has are two tables with date fields. Each table can have multiple rows.

The first table is called Travel and the date field variable of that table is called Date. The second table is called Cost_Distribution and it has two date fields, the first field's variable is Start_Date and the second field's variable is called End_Date.

How do I code it to prevent the Start_Date field from being able to select a date prior to the first row Travel table's Date field? I also need the End_Date field to be limited to the last instance of the Travel Date field.

 

Thanks

Hi Michael,

If you are using classic form designer, this is quite difficult to prevent the date selection based on the other variable's value, because the datepicker is from 3-rd party, it's hard to customize it to only allow a specific scope of dates. If you wants to validate if the date is valid or not, Forms use parsley js to do frontend validation, you have to write your own validators and apply it to start_date and end_date fields. 

In the new designer, we are working on a feature to limit the date selection to only specific dates, and support reading the scope from other variables, this feature id is 484964. It's still under development and can be ready in next release.

Correct, this would be much easier in the new designer. The feature exists in cloud, and will be coming to self-hosted in v12. The feature is documented here for cloud https://doc.laserfiche.com/laserfiche.documentation/en-us/Default.htm#../Subsystems/ProcessAutomation/Content/Forms-Current/Form-Fields/Date-and-Time.htm?Highlight=date%20fields
