Hand over parameters from a MediaWiki template to a included one - mediawiki

Question

I'm using the MediaWiki extension DynamicPageList (third-party) which can be used as a template:
{{#dpl:
|category=foo
|notcategory=bar
}}
I try to use this template in one of my templates which uses more parameter e.g.:
{{myTemplate
|category=foo
|notcategory=bar
|mypara1=bla
|mypara2=lala
}}
myTemplate looks like this:
do something with mypara1
...
do something with mypara2
...
{{#dpl:
|category=foo
|notcategory=bar
}}
I know my parameters but #dpl: can use one or many parameters.
How can I separate my parameters from the #dpl: ones? And how can I just hand over the parameters which belongs to #dpl:?
Thanks,
Ray

Answer 1

Finally I came up with the following solution:
DPL has an additional template #dplreplace. I'm using this to parse my parameters.
Call the template:
{{myTemplate
| filter=category:foo;notcategory:bar
| mypara1=bla
| mypara2=lala
}}
In the template I replace the : by = and ; by {{!}}.
{{#dpl:
| {{#dplreplace: {{#dplreplace: {{{filter}}} | /:/ | = }} | /;/ | {{!}} }}
| ordermethod = sortkey
| suppresserrors = true
}}
NOTE: {{!}} is a template which is replaced by |.

Maybe I'm misunderstanding your issue, but you can just pass the parameters on to DPL, just like you would to a template, or another parser function. You might want to add an empty default in most cases:
myTemplate:
do something with {{{mypara1}}}
do something with {{{mypara2}}}
{{#dpl:
|category = {{{category|}}} <!-- default to empty string -->
|notcategory = {{{notcategory|}}} <!-- default to empty string -->
}}
Call it like this:
{{myTemplate
|category=foo
|notcategory=bar
|mypara1=bla
|mypara2=lala
}}
Will work with missing parameters too:
{{myTemplate
|category=foo
|mypara1=bla
|mypara2=lala
}}
