PHPRunner General questions

I've been trying to work out how to implement a solution for the situation where I need to record a 100 or so predefined measurements for one master (boat) added. Each measurement has a spec, min value and max value which do not change for a new boat plus the actual measurement which is unique to the new boat.

I'm sure the solution is relatively simple but I would be grateful for a pointer in the right direction.

Thanks

Unless I'm missing something this looks like a simple master-details relationship between two tables.
Probably you need to elaborate what exactly causes the trouble.

Its not trouble with the software; its trouble with getting my head around the solution!

I have a table of over 600 boats. For each boat I want to be able to add 100 or more detail records with each record having 4 fields. 3 fields are unchanging as they define the rule spec, max measurement and min measurement. the fourth field will record the actual measurement taken for that boat. So I want to be able to add the 100 detail records in one fell swoop and then enter the actual measurements in the fourth field.

Sorry, still don't get what causes the trouble here.
Add master record, add as many details as you need. Sounds pretty straightforward.

OK. The solution I have in mind means that I need to be able to append 100 measurement records from a separate table as detail records once I have added a master record for the boat. Then I can then edit each of the 100 detail records I have added with the actual measurement for that boat.

What code do I need to append the records and which is the most appropriate event to hold it?

So the question is how add 100 details records automatically after master record is created?
To do so you need to implement AfterAdd event of master table.
To insert a record use DAL's method Add():

http://xlinesoft.com/phprunner/docs/data_access_layer.htm
To insert 100 records use PHP for statement:

for($i=1;$i<=100;++$i)

{

// add one record
}
