WordPress Remote Posting with PHP

To remotely write or post content to a WordPress.com site using PHP, you can leverage the WordPress REST API. Below is a PHP example that shows how to remotely write or create a post on a WordPress.com site.

Prerequisites:

1. You must have a WordPress.com account.
2. You need to get a WordPress.com API key or OAuth2 token for authentication.
3. The Jetpack plugin must be installed and connected on a self-hosted WordPress site if you're posting to a self-hosted site.

Steps:

1. Get API Token:
   • Go to WordPress.com Developer page and create an application to get the OAuth2 credentials.
2. Use PHP cURL to Make API Requests:
   The example below shows how to create a new post.

PHP Example:

<?php

// Your WordPress.com OAuth2 token (get this from WordPress Developer console)
$access_token = 'your_access_token';

// The WordPress.com blog/site ID (or you can use the domain)
$site_id = 'your_site_id';

// The REST API endpoint for creating a post
$api_url = "https://public-api.wordpress.com/wp/v2/sites/$site_id/posts";

// Post data
$post_data = array(
    'title'   => 'Remote Post Title',
    'content' => '<p>This is the content of the post created via PHP remotely.</p>',
    'status'  => 'publish' // 'draft' for draft post or 'publish' to publish immediately
);

// Setup cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post_data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer ' . $access_token,
    'Content-Type: application/json'
));

// Execute the request
$response = curl_exec($ch);

// Check for cURL errors
if(curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
} else {
    // Decode the response
    $response_data = json_decode($response, true);

    // Output the post ID and URL of the newly created post
    echo "Post ID: " . $response_data['id'] . "\n";
    echo "Post URL: " . $response_data['link'] . "\n";
}

// Close cURL session
curl_close($ch);

?>

Explanation:

• $access_token: The OAuth2 token you get after registering your application on WordPress.com.
• $site_id: This is either the WordPress.com site ID or the domain name (e.g., example.wordpress.com).
• $api_url: The endpoint for posting new content. For a self-hosted site, the URL would be different.
• curl_setopt: This configures the cURL request. The Authorization header includes the Bearer token for authentication.

Notes:

• Replace the your_access_token and your_site_id with the actual values from your WordPress.com account.
• You can also modify the status parameter to draft if you don’t want the post to be published immediately.

This will remotely create a new post on your WordPress.com site using PHP.

Below is another example based in Linux CLI:

curl -X POST https://public-api.wordpress.com/wp/v2/sites/<your_site_id>/posts \
-H "Authorization: Bearer <your_access_token>" \
-H "Content-Type: application/json" \
-d '{
  "title": "Post Title from CLI",
  "content": "<p>This is the content of the post created using Linux curl command.</p>",
  "status": "publish"
}'
