Link to individual fragment

[regystro]

Hi.

Trying to figure out how to accomplish this, but having read all documentation, I can't get it to work.

I have a single page named datapage containing all data objects of class "item":

<data myitem #item1>
SampleField: One
</data>

<data myitem #item2>
SampleField: Two
</data>

<data myitem #item3>
SampleField: Three
</data>

and so on... What I want is a simple table showing direct links to each item, so I use:

<table ?item> 
?item is a: myitem
</table>

And I end having a table which links to datapage#item1, datapage#item2 and datapage#item3

But having a look at the HTML code I've found there are no HTML sections / anchors defined as #item1 .. #itemN, so no direct linking possible, and that's what I need. When I click on the links I'm always redirected to the top of the datapage. Is there any way to do this? Am I missing anything in the item / fragment approach?

Thanks a lot in advance. Greetings.

You are not missing anything. The current way of handling fragments is due to the developmental nature of the plugins: at the moment, the fragments are used to build links, but they are not rendered to HTML. This is because I have yet to find a clean way to mesh the generation of these identifiers with the default wiki header identifiers.

What does work is the following:

===== item1 =====
<data myitem #item1>
SampleField: One
</data>

That way the rendered links will jump you to the header.

Does that help you out?

[regystro]

Yes it kind of does. And I've been able to avoid duplicated headers by using Wrap plugin and including a custom CSS class this way:

.wrap_header-hidden h2 {
    visibility: hidden;
    position: absolute;
}

Then my data entry looks like this:

<WRAP header-hidden>
===== item1 =====
</WRAP>
<data myitem #item1>
SampleField: One
</data>

So let's say this workaround works for me :+1:

Thank you!!

Good to hear!

I'll leave this issue open, since there should be a solid solution for this problem. (Workarounds are nice, but we really want this to work out-of-the-box.)

Hi.

I managed to write a little mod and got it working. Now there's no need to include the headers (===== item1 =====) nor the CSS to hide them as stated in some posts above :)

Just wanted to share in case anyone is interested.

Strata Plugin version 2017-03-28 File: lib\plugins\strata\syntax\entry.php Replace the original line #252 $R->doc .= '<div class="strata-entry" '.(isset($currentPosition)?'id="'.$currentPosition.'"':'').'>'; by all this code:

// ## internal link MOD ##
$divid = $data['entry'];
resolve_pageid(getNS($ID),$divid,$exists); // convert entry title to id using DokuWiki function
// translate id to match the link generated by Strata Plugin
$divid = preg_replace('/[\.:]/','',$divid); // remove unwanted characters
$divid = preg_replace('/#/','_',$divid); // replace particular characters
if (isset($previousPosition) or isset($nextPosition)) {
    // has fragments
    if (!isset($previousPosition)) $R->doc .= '<span id="'.$divid.'"><span>'; // added as bookmark to first fragment
    $R->doc .= '<div class="strata-entry" '.(isset($currentPosition)?'id="'.$currentPosition.'"':'').'>'; // yep, that's the original line
} else {
    // single entry
    $R->doc .= '<div class="strata-entry" '.(isset($currentPosition)?'id="'.$divid.'"':'').'>'; // use our generated id instead
}
// ## END internal link MOD ##

You may use this code to test it:

~~NOCACHE~~
<data myitem #item1>
SampleField: One
</data>

\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

<data myitem #item2>
SampleField: Two
</data>

\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

<data myitem #item3>
SampleField: Three
</data>

\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

<data myitem #item4>
SampleField: Four
</data>

\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

<data myitem #item4>
SampleExtraField: Another fragment
</data>

\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\

<table ?item> 
?item is a: myitem
</table>

Now you can click on the links at the table and they take you to the related data entry.

Greetings :)
