Summary

Usage

fetch( 'content', 'collected_info_count',
       hash( [ 'object_attribute_id', object_attribute_id, ]
             [ 'object_id',           object_id,           ]
             [ 'value',               value                ] ) )

Parameters

Returns

The number of collections (as an integer).

Description

This function counts the number of collections based on the provided parameters. An object's ID number (using the "object_id" parameter) or an object attribute's ID number (using the "object_attribute_id" parameter) must be specified. In addition, it is possible to filter out collections that match a certain value. This is typically useful when it comes to counting the number of times a specific value was submitted to a poll. If the "value" parameter is used then the "object_attribute_id" parameter must also be provided. The function returns a positive integer if the system is able to find collections matching the given parameters; if not, zero will be returned.

Examples

Example 1

{def $collections=fetch( 'content', 'collected_info_count',
                          hash( 'object_attribute_id', 42,
                                'object_id',           20,
                                'value',                1 ) )}
{$collections}

Outputs the number of times attribute #42 for object number 20 has collected "1".
