Page.RequestNumber Method
The RequestNumber method retrieves a value from a URL query string or form post variable and converts it to a number based on the specified or default locale.
Optionally, RequestNumber checks the converted number against the specified range, and validates it based on the specified locale.
Syntax
Page.RequestNumber( Name, Default, LowNumber, HighNumber, Locale)
Parameters
- Name
- The name of the URL query string or form post variable to retrieve.
- Default
- Optional. The value to return if the requested URL query string or form post variable is not present or contains no value. If this parameter is not supplied, the method returns Null in this case.
- LowNumber
- Optional. A number value that specifies the low end of the range against which to validate the converted value.
- HighNumber
- Optional. A number value that specifies the high end of the range against which to validate the converted value.
- Locale
- Optional. A number that specifies the locale to use to convert Name. If this parameter is not used, RequestNumber uses the value of the DataFunctions object's Locale property.
Example
In the following example, the value of a field on the purchase form (filled out by the customer) is read into the variable cc_expmonth. Because the Default parameter is specified as null, RequestNumber will return Null if the field is empty or missing, or if the month typed in the field is outside of the range of 1 to 12:
cc_expmonth = page.RequestNumber("_cc_expmonth", null, 1, 12)
