EDD_Download

The EDD_Download class is used for getting data about a specific Download, creating new Downloads, and editing existing Downloads.  The public properties that may be managed with this class are:

• $ID = 0;
• $post_author = 0;
• $post_date = ‘0000-00-00 00:00:00’; 
• $post_date_gmt = ‘0000-00-00 00:00:00’; 
• $post_content = ”;
• $post_title = ”;
• $post_excerpt = ”;
• $post_status = ‘publish’; 
• $comment_status = ‘open’;
• $ping_status = ‘open’;
• $post_password = ”;
• $post_name = ”;
• $to_ping = ”;
• $pinged = ”;
• $post_modified = ‘0000-00-00 00:00:00’; 
• $post_modified_gmt = ‘0000-00-00 00:00:00’; 
• $post_content_filtered = ”;
• $post_parent = 0;
• $guid = ”;
• $menu_order = 0;
• $post_mime_type = ”;
• $comment_count = 0;
• $filter;

Note: The above properties are inherited from and identical to the properties in WP_Post.

Creating a Download

To create a new download you first instantiate the class and then run the create() method.

$new_download = new EDD_Download;
$new_download->create();

This will create a single Download with default settings, which are a Draft with the title of ‘New Download Product’.

The create method uses 
wp_insert_post(), so you may pass any arguments to create() that wp_insert_post() can accept.  Something like this would work fine:

$new_download = new EDD_Download;

$download_args = array(
	'post_title'    => 'My eBook',
	'post_content'  => 'This is my eBook. Nice long description.',
	'post_status'   => 'publish',
)
$new_download->create( $download_args );

Loading an Existing Download

This is accomplished simply by passing a Download ID to the class name during instantiation.

Example:

$my_download = new EDD_Download( 1492 );

Data Fetching Methods

EDD_Download has a variety of method for getting data about the Download, manipulating meta data, and testing for various things.

get_price()

This method returns the price of the Download in double format, with no currency symbol.

$download_price = $my_download->get_price();

Returns: a double, like 9.99. Math may be done on this result.

get_prices()

This method returns an array of the variable prices of the Download in double format, with no currency symbol.

$variable_prices = $my_download->get_prices();

Returns an array of prices like this:

Array

        (
            [index] => 1
