Dear Sirs,

In an appointment form with a "Date and Time Picker" named as "appointment_on"
but the client do not allow to keep any data into web site database for avoid keeping personal / sensitive data, the form need to direct send to client given email.

However the client also need the "appointment_on" do no show any reserved data and time
e.g Public user A select 2025-07-18 09:30 thus, Publish user B cannot select this one

I am thinking using "mapping" to insert any appointment "ID", "Date and Time Picker" into a #__asec_appointment which do not keep any personal data

Then at "Date and Time Picker" Default Value
can we have a php script to exclude any record of data and time found from #__asec_appointment
so 2025-07-18 09:30 is not selectable by Public user B ?

Can you teacg me your php script for this function ?

Thanks indeed
