Lists all the form variables and parameters passed to the current page.

[formvariables]Form Variable Tags[/formvariables]

To display a list of all the form variables available, put a [formvariables] context into a template.

This context is extremely useful to debug a form


Example:
The following are all the form variables available to this page:

[formvariables]
[index],[name],[value]

[/formvariables]

The [formvariables] context has optional parameters placed within the beginning tag in order to modify the list of form variables produced.

Example:
The following are the values of all the form variables with the name "text":

[formvariables name=text&exact=T]
[index],[value]

[/formvariables]

Listing the variables with a given name is useful for getting the results of a multiple select list or multiple checkboxes with the same name.

The following parameters are optional to the [formvariables] context:
ParameterDescription
Name(Optional) The name of the field to list.
 Exact(Optional) T(rue) or F(alse) whether to exactly match the name of the parameter or match any name that contains the "name" value. (Default value is true).
Form(Optional) Use form=include to retrieve the list of form variables from the [include file=xxx&var1=yyy&var2=zzz] tag in this template.


The following tags are available inside a [formvariables] context:
TagDescription
 [name]the name of the field.
 [value]the value associated with the field.
[index]A number from 1 to the total number of fields, indicating this field's index placement in the list.
[break]From version 8.1, if the [formvariables] context sees the [break] tag while executing a loop, it will stop looping, once it finishes the current loop. Thus the [break] tag should only appear in a [showif] statement that is evaluated at the end (bottom) of the loop.
