Restrict the request submission

[Community Alums]

Hi All, 

Having a requirement that, 

We are having a catalog form, where it contains three fields

1- Student name (reference to user table)

2- Course( reference to course table)

The validation that we need to set on the form before submission is

> If the student is submited a request for a course (which is active ) restrict the another request submission for the same course. 

> if the student submitted a three course requests need to restrict not to submit another one. (limit is three requests submission which are active. 

Need suggestions to achieve this.

Hi @Community Alums,

You can create a onsubmit client script along with Script Include Ajax call checking for no of open request by requested by and see if the active course is already submitted.

I hope this logic will help you build the code. Let me know if any questions...

Hello @Community Alums ,

It can be done via the OnSubmit client script.

onSubmit() script runs when a form is submitted. Typically, you use an onSubmit() script to validate things on the form and ensure that the submission makes sense. As such, onSubmit() scripts can potentially cancel a submission by returning false.
