Page.RequestDefault Method

The RequestDefault method retrieves a value from a URL query string or form post variable and returns the value as a string.

Syntax

Page.RequestDefault(Name, Default)

Parameters

Name: The name of the URL query string variable to retrieve.
Default: Optional. The value to return if the requested URL query string or form post variable contains an empty string or a Null, or is not present in the request string. If this parameter is not supplied, the method returns Null in this case.

Remarks

This method is designed so that if a field on a form is blank, or the form does not contain the field, the value returned by default is Null. Null is generally the appropriate value to store to a database when a value is not present. If you need the result to be an empty string in the case of a missing value, supply an empty string as the Default parameter, as in the following example:

Page.RequestDefault("shopper_phone", "")

Example

The following example attempts to retrieve the value for the URL query string variable shopper_phone. Because no Default argument is supplied, if this URL query string variable has no value, the call to RequestDefault returns Null:

shopper_phone = Page.RequestDefault("shopper_phone")
