[opencms-dev] retreiving content resources by property (second time)

[Andreas Zahner]

Osama,

try the following method from the CmsObject:

    /**
     * Reads all resources that have a value (containing the specified
value) set 
     * for the specified property in the given path.<p>
     * 
     * Both individual and shared properties of a resource are checked.<p>
     *
     * @param path the folder to get the resources with the property from
     * @param propertyDefinition the name of the property to check for
     * @param value the string to search in the value of the property
     * 
     * @return all <code>{@link CmsResource}</code> objects 
     *          that have a value set for the specified property in the
given path.
     * 
     * @throws CmsException if something goes wrong
     */
    public List readResourcesWithProperty(String path, String
propertyDefinition, String value) throws CmsException;

To get an initialized CmsObject on your JSP, use the method of the
CmsJspActionElement: getCmsObject() or use it in your customized collector
code;

Hello all

We are building an OpenCMS based news website whereby articles will be
displayed. An article would typically contain a title, author, date,
section, etc. This article is implemented in XML content.

The problem is the following: if I want, for example, in a full article view
to get the "latest articles written by this author", how can this be done? 

The solution I thought of was by building a custom collector for my articles
that can filter them by a custom property called "author-name" for example.

I have worked with other CMS software and this capability comes out of the
box: you can query the system for pieces of content based on metadata
(a.k.a. properties) values. For example: get me all articles with property
author-name=abc (or even use wildcards)

Is this already available? Or do I have to build the collector? If it is
available, how do I do it?

Thanks a lot.
