How to navigate and get a specific json object in URL?

Question

I getting a json from a url but it has lots of objects, how would I only get the slugs giving the json provided below?

I don't mind it either in php or js, I mean on the one hand I need to know how to get what object I want using php or js, on the other hand I am wondering if we can get an object providing a parameter in the url

[

      "name":"AMICI",
      "slug":"amici",
      "taxonomy":"category",
      "parent":184,
      "meta":[

How would I get a list of all "slug":" with their value like "slug":"amici" in a url?

Like http://example.com/ing/wp-json/wp/v2/categories/names

Are you referring to the property in each object named "slug"? — guest271314

In JavaScript you can use Array.prototype.map() and destructuring assignment

let res = data.map(({slug}) => slug)

rob.m Over a year ago

where would you define the URL and what Is it {slug}, didn't know about that

guest271314 Over a year ago

@rob.m What URL? What do you mean by "define"? See developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

rob.m Over a year ago

yeah I mean the DATA, I need to get data from a url from another web site with REST api

guest271314 Over a year ago

@rob.m What data? This is the question at OP "how would I only get the slugs giving the json provided below?"

guest271314 Over a year ago

@rob.m Not following what you mean. The code at the answer gets all values of properties named "slug" and returns an Array containing those values

You can use map and destructuring assignment

let data = [{"id":580,"count":0,"description":"qwer","link":"http:\/\/example.com\/ing\/category\/persone\/414qwer1324r-qewr1233423\/","name":"414qwer1324rqewr1233423","slug":"414qwer1324r-qewr1233423","taxonomy":"category","parent":183,"meta":[],"_links":{"self":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories\/580"}],"collection":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/taxonomies\/category"}],"up":[{"embeddable":true,"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories\/183"}],"wp:post_type":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/posts?categories=580"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}},{"id":586,"count":1,"description":"asdfasd","link":"http:\/\/example.com\/ing\/category\/persone\/add-person\/","name":"Addperson","slug":"add-person","taxonomy":"category","parent":183,"meta":[],"_links":{"self":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories\/586"}],"collection":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/taxonomies\/category"}],"up":[{"embeddable":true,"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/categories\/183"}],"wp:post_type":[{"href":"http:\/\/example.com\/ing\/wp-json\/wp\/v2\/posts?categories=586"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}]

let op = data.map(({slug})=> slug )

console.log(op)

In PHP you can do it with array_column function:

$slugs = array_column($posts, 'slug');

i mean are you suggesting to get the json as a url like $posts = myUrl and then run that?

Andrii Filenko Over a year ago

You can try $posts[array_search('yourUrl', array_column($posts, 'slug'))] to get needed post. To decode your string to $posts array, use $posts = json_decode($_POST['posts'], true);
