Script step that validates a field

Hi, I'm looking for a script step (or custom function) that will allow me to check the validation rules associated with a field from within a script... (so I can do something like If (field passes validation check)...

The problem is that when I use the "commit record" step in the script, the user gets presented with the error message defined in the field options settings from within the database manager window and the script pauses for their input (revert or cancel). I'm looking for someway to prevent that message box from popping up and scripting my own procedure (revert the record and show a different dialogue)

I've already looked at this (http://fmforums.com/forum/topic/72788-scripting-field-validation/) but I'm looking for a way to do this purely from within a script (without creating a new TO) and that uses the validation rules set in the database manager.

thanks!

Thanks,

Ok , now I'm coming at this from a different angle...How can I create a script step that searches in the same field (with the same name in each table) in which ever table you're currently in for duplicates using the "!" operator, and then counts the number of records found?

in this example (which uses imaginary functions that don't exist to help me explain) each table has a field named "FIELD_TO_BE_SEARCHED"

I want something like this: Count ( Find ( Get (LayoutTableName) & ::FIELD_TO_BE_SEARCHED) )

thanks!

Don't confuse functions with script steps. To get the results of a find, you must actually perform a find (and lose your current found set in the process - though this can be solved by opening a new window for the find).

You can use the Set Field By Name[] step to avoid hard-coding the field to be searched.

Just to make sure we understand the starting point: there is no good solution for this. When Filemaker added the OnObjectValidate trigger, they did not add a IsUnique() function at the same time. As a result, there is no elegant way to predict the result of this type of validation (and perhaps some other types as well).

There is a very big difference between a reference to a field and the field's name as text.

GetField ( TableICareAbout::FieldICareAbout )
 

looks at the contents of FieldICareAbout, then tries to to find a field so named in order to get its contents. See the Arrow/Target/Bullseye examples in the help.




GetFieldName ( TableICareAbout::FieldICareAbout )
 

returns the name of the referenced field as text, i.e. "TableICareAbout::FieldICareAbout". From this, it should be obvious that:




GetField ( GetFieldName ( TableICareAbout::FieldICareAbout ) ) 



is the same as:




GetField ( "TableICareAbout::FieldICareAbout" ) 



and very different from:




GetField ( TableICareAbout::FieldICareAbout )
