If a host does not allow readfile() to access files via URL, then define this in functions.php or any custom plugin:

define('EDD_READ_FILE_MODE', 'header');

When this constant is defined to “header”, Easy Digital Downloads will use header(“location:” . $file_url) for directing the user to download the file. This is not as secure so should only be used when readfile() does not work.

The default position is 15, but if you want to change it, place this in your functions.php or any custom plugin:

define('EDD_MENU_POSITION', 25);

25 is the new position of the menu. Any valid number from this page can be used.

Note: this constant has been removed from v1.0.8.5 and later. The issue does not exist past 1.0.8.4, so this constant is not needed.

By default, EDD chooses PHP sessions as they are typically more performance friendly than database driven session handling, and help avoid issues with some object caching plugins and their shortcomings with the transient option types.

In some cases, servers / hosting may not support PHP sessions, which can cause EDD to not function properly. If that’s the case, you’ll need to override the default by setting EDD PHP Sessions to false. All this does is tell EDD to use a different method to keep track of a user on the site.

Empty Cart

The checkout page reporting Empty Cart when an item should be added is a common symptom of PHP sessions not supported by the server. Please review Shopping Cart Is Empty at Checkout prior to disabling sessions as there are other reasons this could be happening.

If you need to change this default:

Place this constant in your wp-config.php file to disable EDD PHP Sessions:

define( 'EDD_USE_PHP_SESSIONS', false );

If you need to re-enable EDD PHP Sessions, either delete the line above or set it to

define( 'EDD_USE_PHP_SESSIONS', true );

If you are unsure of how to edit your wp-config.php file, please consult the official WordPress help page on editing the file.

Note: you must place this code above the line that says:

/* That's all, stop editing! Happy blogging. */

It is safe to leave the constant in wp-config.php indefinitely.

How do EDD PHP Sessions work?

If this constant is defined, Easy Digital Downloads will use PHP $_SESSION for storing cart data. By default, when the EDD_USE_PHP_SESSIONS constant is not defined, EDD will look to see if the server supports PHP based sessions and choose PHP session handling going forward. If the session_start function is not supported, then EDD falls back to the WP_Session class, which is a combination of browser cookies and database rows stored in the wp_options table.

Place the following code snippet to change the slug of the download post type:

define('EDD_SLUG', 'my-downloads-slug');

The best way to apply the code snippet to your site is with a plugin that allows you to add custom code to your site. To do that, we recommend using WPCode. Click here to learn how to apply the snippet using WPCode.

Note: after doing this, you should resave your permalink structure for the changes to fully take effect.
