Redirect route including language


#1

Trying to redirect same link on multilingual page to its proper languages files e.g.:

/en/link: ‘someaddress.com/en/file.ext
/cs/link: ‘someaddress.com/cs/file.ext

Is it possible to do it some easy way?


#2

Share more details. U want to create a link in twig or markdown? Is it an external file u want to link?


#3

the task was to create link with exact addres like mysite.com/cs/the-link which is pointing to pdf file
so i’ve managed to create redirect using site.yaml redirect section,
but then realized, that it doesn’t work in other language e.g. mysite.com/en/the-link

I mean, it’s pointing to same address file, in my case the cz pdf, but I have to pdfs, czech and english …


#4

In Twig you might try '/' ~ page.language ~ '/path/to/file.pdf'


#5

If i link an img in a md file like this:

[link-name](blah.jpg)

then it is availaible by the following routes:
www.blah.de/de/subdir/blah.jpg
www.blah.de/en/subdir/blah.jpg
www.blah.de/subdir/blah.jpg

You can even disable the language in routes in the system settings.


#6

That’s cool @npetri

I wonder, is twig that smart or has Grav added that smartness?


#7

Haha, no twig cant handle routes. This is a really superveryverybiggestawesome builtin feature of grav. :wink:


#8

Just learned a word which wasn’t in my vocabulary but found it in the urban dictionary


#9

I mean i need to put somehow to site.yaml
redirect:
mysite.com/en/mylink: ‘absoluteurl/myfile-EN.pdf’
mysite.com/cz/mylink: ‘absoluteurl/myfile-CZ.pdf’

I hope I’ve explained it correctly.


#10

Ahhhh now i get u. But i have no idea if its possible. U are able to create any route to a page, but to a file i dont know.


#11

no, in fact, redirecting in multilingual sites is done after the lang slash … as written in docs


#12

I was able to set a redirect to a particular file like this:

/de/hijpeg -> /subdir/hi.jpeg

The language indicator will be added automatically to the target. So u may try in your case:

/en/mylink: /myfile-EN.pdf
/cz/mylink: /myfile-CZ.pdf

But your pdf files need to be inside the pages folder.


#13

A different approach…

I’ve added an onPageContentRaw function to the theme. The function searches the Markdown code for the PDF and replace it by a proper <a>

All pages contain the same language neutral Markdown code [PFD](/user/pages/images/mypdf.pdf).

For example, when the English page is requested by the user, the Markdown code [PDF](/user/pages/images/mypdf.pfp) will be replaced by <a href="/user/pages/images/mypdf-en.pdf">PDF</a>

All pdf files are stored in /user/pages/images and are named mypdf-en.pdf, mypdf-cz.pdf etc.

public function onPageContentRaw(Event $e)
{
    $content = $e['page']->getRawContent();
    // Regex of Markdown url pattern
    $needle = '/\[(.*?)\]\((\/user\/pages\/images\/mypdf)\.pdf\)/';
    // Regex of replace pattern
    $replace = '<a href="$2-' . $e['page']->language() . '.pdf">$1</a>';
    $content = preg_replace($needle, $replace, $content);

    $e['page']->setRawContent($content);
}

This code will only be called once when the page is being processed. Thereafter the page will be fetched from cache.

hey, this one seems really elegant, but doest it really work for you exactly like this? I get 404 as I try it this way ///
my site.yaml:

redirects:
/en/gdpr: /GDPR_OKTOURS_EN.pdf
/cs/gdpr: /GDPR_OKTOURS_CZ.pdf

is it like this?


#15

This actually isn’t that bad of an idea :slight_smile:
If you’d need to link different files (same files but other language…)
You could even do it by using the page.language in an if statement if you’d really want to,

  {% if page.language == "en" %}
    href = someaddress.com/en/en_file.ext
  {% elseif page.language == "cs"
    href = someaddress.com/cs/cs_file.ext
  {% else %}
    href = provided_default.ext
  {% endif %}

Hope it helps you some way :slight_smile:


#16

oh man, this is really cool but i need actually to serve the redirect, and this just process afterwards, you know, client have some address which is exactly the same … e.g. mysite.com/en/gdpr … and afterwards i can use your simple answer…eh


#17

I was able able to define and test this configuration:

redirects:
/de/read-de: /externals/doc-de.pdf
/cz/read-cz: /externals/doc-cz.pdf

The de and cz language was added to system.yaml as a supported language. It works with ‘Include default language’ enabled or not.

There are always a few possibilties to solve a problem, in the end it doesn’t really matther how you do it, it’s good if it works :slight_smile:
