[Plugin: Polylang] How to query for posts in the page language?

Could you tell me where I can find this theme ?

I would also like to know this!

I am trying to query a custom post type and i only want to return posts of a certain language.

There must be an easy way to do this that i have overlooked.

Please help!

@tuneintokyo,
In your case it’s in fact quite easy. Just query your custom post type together with the language you want like that:

yoursite.com/?post_type=your_custom_post_type&lang=your_language_code

where your_language_code is the 2 characters code you chose for the language.

For berryblue031, it would be a bit more complex as each category is normally affected one unique language.

for custom post type try something like this (for english lang):

<?php
$loop = new WP_Query(array('post_type' => 'YOUR_CUSTOM_TYPE_SLUG', 'lang' => 'en', 'paged' => get_query_var('paged'), 'posts_per_page' => 10));
while ( $loop->have_posts() ) : $loop->the_post(); ?>

	// html here

<?php endwhile; ?>

Brilliant! I knew it should be easy.
@chouby, @yoyurec, thanks so much for your help!

For berryblue031, it would be a bit more complex as each category is normally affected one unique language.

I can easily make a category for each language. But the theme only allows me to input one category via it’s control panel.

So using that approach given a category id
$cat = get_option(THEME_NAME.'_slider_category'); //this returns an integer
How can I get the id of the related category in the language of the current page?

If there is no ‘nice’ way of doing it I guess I will just have to hack into your cookie variable and hardcode the category id based on it’s value. Though I would rather not have to hack it… I already had to make some hacks because the theme I am stuck with depends on a specific permalink format that your language drop down doesn’t respect and my php / wordpress skills aren’t good enough to modify the theme so I went with the easier route.

Ironically I am a professional C++ developer and some how that meant I have the skills and should make a website for my mother-in-laws bed and breakfast :P..

To manually know the id of a given category is easy. Go in your category admin panel, edit the category and look at the address your browser sent you. It’s something like:
yoursite/wp-admin/edit-tags.php?action=edit&taxonomy=category&tag_ID=5&post_type=post
The number after the tag_ID is the category id you are looking for.

Then to get the language of the current page, no need to play with the cookie. You can use get_locale() which returns something like en_US or get_bloginfo('language') which returns something like en-US.

Finally you can hardcode the category id depending on the language page.

However, if the theme is downloadable somewhere, I would be interested to get the link. I would like to see if I can adapt the plugin to such cases.

The theme is available to download you can get it here, it includes documentation about setting the permalinks

The first problem I had with it, is it requires a staic frontpage and uses is_front_page() in header.php to do special stuff on the front page,but when using your plugin there are multiple front pages (one for each language) and is_front_page was returning false on these pages – to get around this I ended up pulling all the code out of the themes front-page.php and putting it in a template called _front.php, then changing the is_front_page() calls to is_page_template(‘_front.php’), ideally is_front_page() would have returned true for all language versions of the front page.

And the second problem was with your language drop down, when I used it the pages didn’t work at all when referenced with /language/da, and the dirty hack I had to do for that was change the all my front pages to be called “en-home.php” , “da-home.php” etc, and then “modify” your Polylang_Widget href to use my naming scheme instead which is really ugly

// $url = home_url('?lang=');
$url = home_url('');
...
if (this.value == '$default')
   location.href = '$home_url';						else
{
   //location.href ='$url'+this.value;
   location.href = '$home_url' + '/' + this.value +'-home/';
}

Back to topic of the category is it really necessary to hard-code the category id (I was hoping to avoid that). I was kinda hoping there would be a function called getAlternateLanguage($cat_id, get_locale()); that would then return the id of the category in the proper language? I have linked the categories together as language alternatives of each other.

I will take your suggestions into account for v0.5. However you gave me an idea and you may prefer using this alternative for now :

// returns the id of the translation of a term (category, post tag or custom taxonomy)
$translate_cat_id = get_metadata('term', $cat_id, '_lang-'.$slug, true);

where $slug is the two characters code you chose for the language. It should normally be accessible with:

$slug = substr(get_locale(), 0, 2);

Ahhh that is perfect! Thank you.
It’s really great how fast you are at responding on the forum ??

To come back on the two problems you mentioned above:

Unfortunately, the way it is coded in WordPress, I believe there is no way to filter is_front_page() so that it returns true for all front pages in all languages, when using a static front page. I will have to create an alternative function in the coming Polylang API.

I know that the few javascript lines I wrote for the dropdown list in the language switcher widget are far from enough. I did that very quickly to answer a user’s request. It’s on my roadmap to improve this, but I did not decide a time schedule yet. Certainly not for the 0.5 for which the list of new features is already quite long.

You know I would have actually preferred to use the list version of the widget instead of the dropdown, but I didn’t know how to make it layout horizontally. Is it possible?

I will have to include this in the documentation. You are the third to ask. Look here.
