formvariables
To list all the variables that are passed in a form or url, [formvariables] will display them all in name-value pairs.
[formvariables][name] = [value][/formvariables]Parameters
| Parameter | Description |
|---|---|
| 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. |
Tags available inside a [formvariables] context:
| Tag | Description |
|---|---|
| [index] | A number indicating this variable's placement in the list |
| [name] | The name of the variable |
| [value] | The value associated with the variable |
| [break] | From v8.1, 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. |
This context is extremely useful to debug a form.
To display a list of all the form variables available, put a [formvariables] context into a template.
Example WebDNA code:
The following will list all the form variables available to a page:
[formvariables]
[index], [name] = [value]<br>
[/formvariables]The [formvariables] context has optional parameters in order to modify the list of form variables produced.
Example WebDNA code:
The following are the values of all the form variables with the name "text":
[formvariables name=text&exact=T]
[index], [name] = [value]<br>
[/formvariables]
