如何为 ZC31B32364CE19CA8ZFCD150A417ECCE5 应用程序创建 WordPress REST API

Question

I am basically android developer, I also work on PHP to create REST APIs for mobile apps. I am working on an android app, I want to create a WordPress-REST-API for my android app to add users into WordPress wp_user's table through the android app.

For this, i created a REST API in PHP and used wp_create_user() method to add a user into WordPress database. I placed API into 'wp-content/themes/mytheme' directory but it's always showing me this error 'Call to undefined function wp_create_user()', i think wp_create_user() function is unavailable in my API.

I asked from my WordPress friend and he said, you have to create a custom page template and have to call that page from android app but this is illogical fro me. How can I resolve this issue?

<?php
if (!isset($_POST['ins_name'])) {
    die("ins_name  is not set");
}

$ins_name = $_POST['ins_name'];

if (!isset($_POST['ins_email'])) {
    die("ins_email is not set");
}

$ins_email = $_POST['ins_email'];

if (!isset($_POST['ins_password'])) {
    die("ins_password  is not set");
}

$ins_password = $_POST['ins_password'];


function addUserIntoWordpressTable($email, $password) {
      $user_id = wp_create_user( $username, $password, $email );
      echo $user_id;
}
addUserIntoWordpressTable($ins_name, $ins_password, $ins_email);

?>

I want to add users's data into WordPress database through REST API.

Answer 1

Wordpress has it's own built in REST API framework where you can use all the existing functions, and extend it in a clean way without having to worry about REST boilerplate or doing ugly things like making a REST page template.

You can read more about it here: https://developer.wordpress.org/rest-api/

Answer 2

For any WordPress functions to work in your custom folder or api folder you have to include the file wp-load.php in your file.

Like:

require_once($_SERVER['DOCUMENT_ROOT'].'/wp-load.php');

You need to include this file at the top of your php file.

Hope it works for you.
