SETVAR

Sets the value of a variable.

Syntax

<SETVAR 
      NAME="VAR_NAME" 
      VALUE="VAR_VALUE"/>

Parameters

NAME (required)

Name of the variable to set.

VALUE (required)

Value to set the variable to.

Description

The SETVAR tag sets the value of a variable. The value of the variable exists for the duration of the page evaluation unless it is explicitly deleted using REMOVEVAR . For more information about variables, see the Sites Developer's Guide.

Error Numbers

There are no possible errno for this tag.

Example

This example sets the variable "color" to "red".

<SETVAR NAME="color" VALUE="red"/>

The next example assumes that the variable "color" has been set to "red" and appends "and blue".

<SETVAR NAME="color" VALUE="Variables.color and blue"/>
<CSVAR NAME="Variables.color"/>

The browser displays:

red and blue

If a variable was set by loading a file or URL and the content contains Variables.varname syntax, then the variable values can be resolved by:

<SETVAR NAME="myvar" VALUE="Variables.myvar"/>

Any variables as part of the value of myvar are resolved before the value is reset.
