attribute

Summary

Makes it possible to inspect the contents of arrays, hashes and objects.

Usage

input|attribute( [show_values [, level [, table ] ] ] )

Parameters

NameTypeDescriptionRequired
show_values string Extract values in addition to keys, names, etc. No.
level integer The number of levels that should be processed (default is 2). No.
table boolean Return result as HTML table (default) or not. No.

Returns

A string revealing information about the target.

Description

This operator extracts all available keys, attribute names and/or methods that belong to the input parameter (must be either an object, an array or a hash). By default, only the array keys and object attribute names will be revealed. By passing "show" as the first parameter, the operator will also return the values. The second parameter can be used to control the number of levels/children that should be expanded and included in the result (the default setting is 2). A large level value may cause the system to be trapped in a recursive/infinite loop. The returned result is an HTML table containing the retrieved information. If "false()" is passed as the third parameter, the output will be a plain string instead of an HTML table. Please refer to the "Array and object inspection" section of the "Templates" chapter for more information about the use of this operator.

Examples

Example 1

{def $example=hash( 'Name',  'John Doe',
                    'Age',   24,
                    'Phone', '555-3212' )}
 
{$example|attribute()}

The following output will be produced:

                    'Age',   23,
