ILEMAKER FUNCTIONS REFERENCE 247
IsValid
Purpose
Returns 0 (false) if the data is invalid; otherwise, returns 1 (true).
Format
IsValid(field)
Parameters
field - any field name
Data type returned
number
Originated in
FileMaker Pro 6.0 or earlier
Description
Returns 0 (False) if:
• A field contains an invalid value because of a field type mismatch (text in a date field, for
example)
• FileMaker Pro cannot locate (temporarily or permanently) the related table in which the
referenced field is defined
• A field has been deleted from a related table, and therefore the references to that field in the
source table are invalid
Otherwise, it returns 1 (the data is valid).
Note IsValid does not check field validation options defined in the Manage Database dialog box.
Define field validation options to make sure that data is correctly entered into fields during data entry
and import. See Defining field validation.
Examples
IsValid(Datefield) returns 0 if there is non-date data in Datefield, for example if text was
imported into it.
IsValid(Amount) returns 0 if there is only text in the number field Amount.
IsValid(table::field) returns 0 if the related table was renamed and the relationship isn’t
updated with the new filename.
