With this MODX Revolution extra you can generate a xPDO where clause on base of request parameters. This where clause can i.e. be used as pdoRessources or getResources where property. That way you can filter MODX resources with request parameters.



The FilterGetResourcesWhere snippet creates a where clause that can i.e. be used as pdoRessources or getResources where property. It has to be called uncached to work on the request values.

The Snippet uses the following properties:

Property Description Default
fields JSON encoded array of filter => resourcefield combinations. -
where JSON encoded xPDO where clause to filter the resources. -
emptyRedirect ID of a resource, the user is redirected to, when the generated where clause is empty. -
toPlaceholder If set, the snippet result will be assigned to this placeholder instead of outputting it directly. -
varName Name of the superglobal variable that is searched for the filter values. REQUEST

The fields property uses the following syntax:


request_key contains the request key from which the value is retrieved. resource_fields contains a comma separated list of resource fields which are searched by the value. operator is optional and contains the xPDO query operator like =, >, LIKE etc. It defaults to =. If the operator is LIKE, the searched value is surrounded with %, to create a wildcard search in the resource fields. junction is optional and can be set to define the junction between two search query parts. It defaults to empty, which means AND in an xPDO where clause.

The sanitized values of each request key is set as placeholder in <key>_value.

Using the where property, you can combine the created where clause with an additional where clause created i.e. with TaggerGetResourcesWhere.
