web.link question

[rickyhow]

This creates a link to Step 3, but the text for the link is the common ancestor (page.parent).

{{ web.link{uri: page.parent.uri.."/Step_3", text:page.parent.title} }}

Anyone know how I could change the text argument so that it references the Step_3 page?

Can't you just use the following?


{{ web.link{uri: page.parent.uri.."/Step_3"} }}

or


{{ web.link{uri: page.parent.uri.."/Step_3", text:"Step 3"} }}

[rickyhow]

If I use the first option I get the full path. If I use the second option and the page name that I am linking to is changed, then the text may no longer be appropriate.

If I use page.parent.title I almost get what I am looking for - except that it is the name of the parent.

I just need to be able to get the name of page by building a path to it.

[brigettek]

This will give you the title of a page at a given path:



{{ wiki.getpage(page.parent.uri.."/Step_3").title }}

[rickyhow]

Yes that does it - I just needed to make one change (path rather than uri for wiki.getpage).

{{ web.link{uri: page.parent.uri.."/Step_3", text: wiki.getpage(page.parent.path.."/Step_3").title} }}

Thank-you kindly Brigettek!

It looks like you may need this code fragment several times (maybe as part of an instruction manual or something).

You can save yourself some typing and reduce errors by putting it into a template, like this:

Template:StepLink
{{ var p = wiki.getpage(page.parent.path .. "/" .. $0); web.link{uri: p.uri, text: p.title} }}


Now, to use it on the target page, just use this:

To go to the next step click on {{ template.steplink("Step3") }}.

Thank-you much appreciated...
