searchstate:tostring

Converts a searchstate object into its string representation that is suitable for various uses, such as saving in a session variable or packing into a URL.

Syntax

<searchstate:tostring 
      name="objname" 
      varname="varname"/> 

Parameters

name (required)

Input parameter. Name of the object.

varname (required)

Input and output parameter. As input, name of the string that is assigned the string representation on output.

Error Numbers

The possible values of errno include:

Value	Description
-10004	A required parameter is missing.
-13050	General error.

Example

This code serializes a searchstate "origSS" containing a simple constraint and creates a variable which contains the string representation.

<searchstate:create name="ss" />
<searchstate:addsimplestandardconstraint name="ss" attribute="productdesc" value="LU50/90/27"/>
<searchstate:tostring name="ss" varname="searchstring"/>
<ics:getvar name="searchstring"/><br/>

The following code which would probably be in a page called by the above code then uses the variable searchstring passed on the URL to set a new searchstate "newSS" from the string representation. This code then sets this searchstate into an assetset:setsearchedassets tag to constrain the assetset to be used when searching with other assetset tags. The last tag uses this constrained assetset to search for matching assets and fetch a list of values for a different attribute of the returned assets:

<searchstate:create name="newSS" />
<searchstate:fromstring name="newSS" value='<%=ics.GetVar("searchstring")%>'/>
<assetset:setsearchedassets name="as" constraint="newSS" assettypes="Products"/>
<assetset:getattributevalues name="as" attribute="cat2" listvarname="resultlist"/>
<ics:listloop listname="resultlist">
<ics:listget listname="resultlist" fieldname="value"/><br/>
</ics:listloop>
