| Returns | |
| 1 | The data is valid for this F_STRING field. |
| 0 | The data is invalid for this F_STRING field. |
| Description
If a range was specified for the field, vf_st() checks that the string entered falls within the specified range. If the string does not lie within the specified range for the field, VAL_ERR is set to OUTOFRANGE. The form editor will then display the appropriate message. If no range is specified for the field, vf_st() does nothing. Vermont Views validation messages are defined in vv_valmsg.c. |
