Google Blogger PHP client library documentation

Certainly! If you want to interact with the Google Blogger API using PHP, you can use the Google Blogger PHP client library. Below are the steps to get started:

Step 1: Set Up a Google Cloud Project and Enable the Blogger API

Go to the Google Cloud Console.
Create a new project.
Enable the Blogger API for your project.

Step 2: Install Google API Client Library for PHP

You can use Composer to install the required Google API client library for PHP. If you haven't already installed Composer, you can download and install it from getcomposer.org.

In your project directory, create a composer.json file with the following content:

{
    "require": {
        "google/apiclient": "^2.0"
    }
}

Run the following command to install the required library:

composer install

Step 3: Set Up OAuth 2.0 Authentication

Create OAuth 2.0 credentials (client ID and client secret) for your application in the Google Cloud Console. Download the credentials file as JSON and store it securely.

Step 4: Authenticate and Make API Requests

Here's an example of how you can authenticate and use the Blogger API in your PHP application:

<?php

require 'vendor/autoload.php';

// Replace these variables with your credentials and blog ID
$clientID = 'YOUR_CLIENT_ID';
$clientSecret = 'YOUR_CLIENT_SECRET';
$redirectUri = 'YOUR_REDIRECT_URI';
$blogId = 'YOUR_BLOG_ID';

$client = new Google_Client();
$client->setApplicationName('Blogger API PHP');
$client->setScopes('https://www.googleapis.com/auth/blogger');
$client->setClientId($clientID);
$client->setClientSecret($clientSecret);
$client->setRedirectUri($redirectUri);

// If the user has not authenticated, redirect them to the OAuth 2.0 login URL
if (!isset($_GET['code'])) {
    $authUrl = $client->createAuthUrl();
    header('Location: ' . filter_var($authUrl, FILTER_SANITIZE_URL));
} else {
    // If the user has authenticated, exchange the authorization code for an access token
    $client->authenticate($_GET['code']);
    $accessToken = $client->getAccessToken();

    // Store the access token securely (e.g., in a database)

    // Set the access token to make API requests
    $client->setAccessToken($accessToken);

    // Create a Blogger service object
    $bloggerService = new Google_Service_Blogger($client);

    // Example: Get the list of posts from the specified blog
    $posts = $bloggerService->posts->listPosts($blogId);

    // Process and display the list of posts
    foreach ($posts->getItems() as $post) {
        echo 'Title: ' . $post->getTitle() . '<br>';
        echo 'Content: ' . $post->getContent() . '<br>';
        echo '------------------------<br>';
    }
}

Remember to replace 'YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET', 'YOUR_REDIRECT_URI', and 'YOUR_BLOG_ID' with your actual credentials and blog information.

This example demonstrates how to authenticate with OAuth 2.0 and retrieve a list of posts from a specified blog. You can modify and expand this code to perform other actions supported by the Blogger API, such as creating new posts or updating existing ones.

Please note that handling access tokens securely is crucial, especially in production applications. This example does not cover token storage best practices for simplicity. In a real-world application, you should store access tokens securely and implement appropriate error handling and token refreshing mechanisms.

In the Google Blogger PHP client library, the Google_Service_Blogger_Post class provides various methods to set different properties of a blog post. Here are some commonly used methods similar to $post->setTitle($title):

Title: Set the title of the post.
```
$post->setTitle($title);
```
Content: Set the content/body of the post.
```
$post->setContent($content);
```
Labels (Tags): Set the tags or labels for the post. Tags should be provided as an array.
```
$post->setLabels(['tag1', 'tag2', 'tag3']);
```

Summary: Set a summary or excerpt of the post.

$post->setCustomMetaData('summary', $summary);

Slug: Set the slug or URL-friendly version of the post title.
```
$post->setCustomMetaData('slug', $slug);
```
Publish Status: Set the publish status of the post (draft, live, or scheduled).
```
$post->setCustomMetaData('publishStatus', 'live');
```
Published Date: Set the published date and time of the post (in RFC 3339 format).
```
$post->setPublished(date('c'));
```
Updated Date: Set the last updated date and time of the post (in RFC 3339 format).
```
$post->setUpdated(date('c'));
```
Author Display Name: Set the display name of the post author.
```
$post->setAuthor(['displayName' => 'Author Name']);
```

Images: Set images for the post. Images should be provided as an array of image URLs.

$post->setImages(['https://example.com/image1.jpg', 'https://example.com/image2.jpg']);

URL: Set the URL of the post (useful for updating existing posts).
```
$post->setUrl('https://example.com/post-url');
```

Remember, these methods are specific to the Blogger API and the PHP client library. You can refer to the official Google API PHP Client documentation for more details on the methods available for different services and resources.
