Question

• One of my webs contains several categories like "Abbreviation" or "Documents".
• I have created several templates within a web, one for each category.
• Depending on the category, I want to preselect the corresponding template in WebTopicCreator in order to make it easier for the user.
• I know that I can provide special parameters to WebTopicCreator (at the moment it is only "parent").
• I want to give a parameter called topictemplate to WebTopicCreator.
• My question is: How can I change the code in WebTopicCreator in order to preselect the appropriate template within the selection box (the preselected one is "Default template" at the moment)?

Good suggestion to add a template parameter. Just after

<select name="templatetopic" class="twikiSelect">

%IF{"$templatetopic" then='<option value="%URLPARAM{templatetopic}%" selected="selected"></option>'}%

I tried it but it does not work. So I tried

<p>%STARTSECTION{"topictemplate"}%<select name="templatetopic"> <option value="">%MAKETEXT{"Default template"}%</option>%SEARCH{".*Template$" scope="topic" type="regex" nonoise="on" format="<option %IF{"$topictemplate=$topic" then=selected="selected"}%>$topic</option>"}%</select> <a href="%SCRIPTURL{view}%/TWiki06x01/WebTemplateTopics?web=%BASEWEB%">View templates</a> %ENDSECTION{"topictemplate"}%</p>

But it does not work either. I think the compare is wrong because if I do not compare templatetopic with $topic the last template of the selection is shown. But I do not know how to change the compare to be correct.

You need to escape the IF in the format so that it evaluates once per hit, and not just once per search:

format="<option $percntIF{\"$topictemplate=$topic\" then='selected=\"selected\"'}$percnt>$topic</option>"

Thanks. I replaced $topictemplate by %URLPARAM{topictemplate}% because I want to check the given parameter. Now it works but only if the parameter is given. Otherwise the comparision is not correct because %URLPARAM{topictemplate}% is empty. How can I manage the case if %URLPARAM{topictemplate}% is not given?

See TWiki.VarURLPARAM for a description of URLPARAM's default attribute, where you can give, well, a default value in case parameter is empty or missing.

Great! Now it is working. I had some problems with using quotation marks but now it is working. Thanks to all of you for your help!
