WordPress Amazon S3 Plugin

安裝方式

1. Copy plugin files to WordPress wp-content/plugins folder
2. Make sure you create a folder named ‘s3temp’ in your media upload folder and make it writable.
3. Activate the plugin
4. Go to Amazon s3 page under plugins and set up your Amazon S3 credentials
5. This plugin will not create any S3 buckets. You have to create the bucket with public read access and use the same
6. The plugin will not work until all the configs are completed
7. If anything goes wrong just de-active the plugin and blog should go back to its old state

Theme & Plugin Developers can use these examples to make their theme / plugin assets load from CDN

To scan a full HTML Block for images, upload to CDN and replace them if uploaded.

<?php
if(class_exists('S3Plugin')){
    $output = S3Plugin::scanForImages($output);
}
?>

To check if a single media needs to be uploaded to CDN and replaced if uploaded.

<?php
if(is_singular()){
    $attachmentDetails = &get_children( "numberposts=1&post_type=attachment&post_mime_type=image&post_parent=" . get_the_ID() );
    if(!empty ($attachmentDetails)){
        $attachmentDetails = array_shift($attachmentDetails);
        $postImage = array_shift(wp_get_attachment_image_src($attachmentDetails->ID,'thumbnail'));
        if(class_exists('S3Plugin')){
            $cdnImageURL = S3Plugin::getCDNURL($postImage);
            if($cdnImageURL!==FALSE){
                $postImage = $cdnImageURL;
            }
        }
    }
}
?>
