JavaScript API

Frontend JavaScript Functions

Publisher includes JavaScript API for frontend interactions:

// Include Publisher JS library
<script src="/modules/publisher/assets/js/publisher.js"></script>

// Check if Publisher object exists
if (typeof Publisher !== 'undefined') {
    // Use Publisher API
}

// Get article data
var item = Publisher.getItem(itemId);
console.log(item.title);
console.log(item.url);

// Get category data
var category = Publisher.getCategory(categoryId);
console.log(category.name);

// Submit rating
Publisher.submitRating(itemId, rating, function(response) {
    console.log('Rating saved');
});

// Load more articles
Publisher.loadMore(categoryId, page, limit, function(articles) {
    // Handle loaded articles
});

// Search articles
Publisher.search(query, function(results) {
    // Handle search results
});

Ajax Endpoints

Publisher provides AJAX endpoints for frontend interactions:

// Get article via AJAX
fetch('/modules/publisher/ajax.php?op=getItem&itemid=' + itemId)
    .then(response => response.json())
    .then(data => console.log(data));

// Submit comment via AJAX
fetch('/modules/publisher/ajax.php', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
    },
    body: 'op=addComment&itemid=' + itemId + '&text=' + comment
})
.then(response => response.json())
.then(data => console.log(data));

// Get ratings
fetch('/modules/publisher/ajax.php?op=getRatings&itemid=' + itemId)
    .then(response => response.json())
    .then(data => console.log(data));

REST API (If Enabled)

API Endpoints

If Publisher exposes REST API:

GET /modules/publisher/api/items
GET /modules/publisher/api/items/{id}
GET /modules/publisher/api/categories
GET /modules/publisher/api/categories/{id}
POST /modules/publisher/api/items
PUT /modules/publisher/api/items/{id}
DELETE /modules/publisher/api/items/{id}

Example API Calls

// Get items via REST
$url = 'http://example.com/modules/publisher/api/items';
$response = file_get_contents($url);
$items = json_decode($response, true);

// Get single item
$url = 'http://example.com/modules/publisher/api/items/1';
$response = file_get_contents($url);
$item = json_decode($response, true);

// Create item
$url = 'http://example.com/modules/publisher/api/items';
$data = array(
    'title' => 'New Article',
    'body' => 'Content here',
    'categoryid' => 1
);
$options = array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-Type: application/json',
        'content' => json_encode($data)
    )
);
$response = file_get_contents($url, false, stream_context_create($options));
