Custom Queries

[daslicht]

Hi,
I have created several projects with different categories.

Lets say I like to get all projects with the category work.

I have tried something like this:

    $posts = new WP_Query(array( 'category_name' => 'work' ));

or:

    $args = array(
            'category_name' => 'work', 
        );
    $posts = get_posts($args) ;

However in the result i get anytime all posts?

What am I missing, please?

Selecting by id works :

$args = array(
	    'post_type' => 'post',
	    'category' => '1', 
    );

well lay theme is fetching content using wp api http://v2.wp-api.org/, most of the frontend is a javascript application (minified). I'm not sure if you can do much with php here.

Let's say you have a page with an id of 1, and you visit it, then this code would fetch all projects. If you want to fetch only projects of a certain category use "http://yourwebsite.com/wp-json/wp/v2/posts?filter[category_name]=home" as your url

http://laytheme.com/documentation.html#custom-javascript

<script>
Frontend.GlobalEvents.on("newpageshown", function(layoutObj, type, obj){
	if(type == "page" && obj.id == 1){
		//fetch all projects
		jQuery.ajax({
		  url: "http://yourwebsite.com/wp-json/wp/v2/posts"
		}).done(function(result) {
		  console.log(result);
		});
	}
});
</script>

Thank you for the info !

Is there a way to get also the author when using something like this please?

"http://yourwebsite.com/wp-json/wp/v2/posts?filter[category_name]=home"

Or do I need a second query for this ?

[arminunruh]

Good question, if the author is not part of the /posts response, you can add the author by modifying the response.

Here is an example:

Hey you could extend the post response with a field like "categories" that contains the posts categories using that function for example: https://developer.wordpress.org/reference/functions/get_the_category/

here's how to extend the response

Thank you !

When I try to add RE$ST fields I get:

Fatal error: Call to undefined function register_rest_field()

Do I need to include something ?
Do I need to install the WP-api plugin ?

[arminunruh]

Ahw, yeah try:

register_api_field instead of register_rest_field, just change the name.
i have to update the wpapi that comes bundled with lay theme, then register_rest_field will work. until then use register_api_field, its the same function
