Read content -> look for article with same name - link

Has someone tried to do the following:

Automatically read content from a custom field (or as well article body),
process for terms, which have a respective article in database under same name,
then link those terms automatically to the respective article, when displaying the content of the custom field (or article body), which contains it.

Any hints appreciated.

Re: Read content -> look for article with same name - link

That’s not too difficult, but can become time-expensive on huge text blocks (article body). You just need to create Title => link replacements pairs with <txp:article_custom /> and pass them to a replacement plugin.

Re: Read content -> look for article with same name - link

Thank you, etc. What kind of replacement plugin would that be, rah_replace? I looked at your link, but it seemed, it would only work in 4.7? i am on 4.6.2, waiting for the official release

Re: Read content -> look for article with same name - link

The only 4.7 feature my example uses is JSON encoding. You can replace this line:

	"<txp:title escape="json" />" : "<txp:permlink escape="json"><txp:title /></txp:permlink>"

with

<txp:php>
	echo json_encode(parse('<txp:title />')), ' : ',  json_encode(parse('<txp:permlink><txp:title /></txp:permlink>'));
</txp:php>

I wouldn’t recommend using straightforward replacement with rah_replace or other plugin, since it would link also article titles inside links, producing

<a href="#"><a href="#">Title</a></a>

Re: Read content -> look for article with same name - link

So i take it that you use etc_query for this.
I am trying to extract comma-separated terms from a custom field and return them linked to the same field when displayed, but seem to be digging in the dark.

I use

<txp:if_custom_field name="works with">
<txp:variable name="replacements">{
<txp:article_custom break=",">
	<txp:php>
	echo json_encode(parse('<txp:custom_field name="works with" />')), ' : ',  json_encode(parse('<txp:permlink><txp:title /></txp:permlink>'));
</txp:php>
</txp:article_custom>
}</txp:variable>
<txp:etc_query data='<txp:custom_field name="works with" />' 
	replace="//p/text()&={$json_decode({?replacements}|1).strtr({?}|$)}" />
</txp:if_custom_field>

and get no output at all.
Just using <txp:variable name="replacements" /> gives me a lot of output of all kinds of info stored in that custom field in various articles, but Oleg, i am an etc_query newbie.
EDIT: Links generated in txp:variable output look like https://website.net/%22https:////website.net//article-meta-title/%22

Can you give me a hint, please?

No worries, but I need your help.

jayrope wrote #310641:

what terms: article titles, their url titles, ..?

and return them linked to the same field when displayed

So, you want the “terms” to be replaced by article links?

Oleg, exactly, extracting comma-separated article titles from a custom field, then replace the respective entries with links to the respective articles in the same field, only in frontend, so only for display (yet ;).

In fact really cool would be, if i get a live list of existing article titles, when starting to type terms into that custom field in the backend. But that’s version “future”.

Re: Read content -> look for article with same name - link

Then yes, it could be rah_replace, but this should work too:

<txp:if_custom_field name="works with">
<txp:variable name="replacements">{
<txp:article_custom break="," limit="999"><txp:php>
	echo json_encode(parse('<txp:title />')).' : '.json_encode(parse('<txp:permlink><txp:title /></txp:permlink>'));
</txp:php></txp:article_custom>
}</txp:variable>
<txp:etc_query data='<txp:custom_field name="works with" />' markup="raw"> 
	{$json_decode({?replacements}|1).strtr({?}|$)}
</txp:etc_query>
</txp:if_custom_field>

Not sure works with is a good name choice, works_with looks more robust.

Edit: rah_replace version:

<txp:if_custom_field name="works with">
<txp:article_custom limit="999">
<txp:if_first_article>
	<txp:variable name="titles" value='<txp:title />' />
	<txp:variable name="links" value='<txp:permlink><txp:title /></txp:permlink>' />
<txp:else />
	<txp:variable name="titles" value='<txp:variable name="titles" />,<txp:title />' />
	<txp:variable name="links" value='<txp:variable name="links" />,<txp:permlink><txp:title /></txp:permlink>' />
</txp:if_first_article>
</txp:article_custom>

<txp:rah_replace from='<txp:variable name="titles" />' to='<txp:variable name="links" />'>
	<txp:custom_field name="works with" />
</txp:rah_replace>
</txp:if_custom_field>
