I am trying to have a button on the users Profile > Cover Image page that says simply "Remove Cover Image". The theme they are using does a template override of the cover image as seen here: http://pastebin.com/XQPpiVYs
I know Buddypress has this option once a user has uploaded a cover image, then the option to delete it is available immediately after upload but how can I add a button in that allows them to delete the cover photo at anytime instead of directly after upload?
I know I dont want to edit the core but I found the action responsible for this. Is there a way I can create a button that will call this action and remove the users cover photo?
in buddypress/bp-core/bp-core-attachments.php:
/**
* Ajax delete a cover image for a given object and item id.
*
* @since 2.4.0
*
* @return string|null A json object containing success data if the cover image was deleted
* error message otherwise.
*/
function bp_attachments_cover_image_ajax_delete() {
// Bail if not a POST action.
if ( 'POST' !== strtoupper( $_SERVER['REQUEST_METHOD'] ) ) {
wp_send_json_error();
}
$cover_image_data = $_POST;
if ( empty( $cover_image_data['object'] ) || empty( $cover_image_data['item_id'] ) ) {
wp_send_json_error();
}
// Check the nonce
check_admin_referer( 'bp_delete_cover_image', 'nonce' );
// Capability check
if ( ! bp_attachments_current_user_can( 'edit_cover_image', $cover_image_data ) ) {
wp_send_json_error();
}
// Set object for the user's case
if ( 'user' === $cover_image_data['object'] ) {
$component = 'xprofile';
$dir = 'members';
// Set it for any other cases
} else {
$component = $cover_image_data['object'] . 's';
$dir = $component;
}
// Handle delete
if ( bp_attachments_delete_file( array( 'item_id' => $cover_image_data['item_id'], 'object_dir' => $dir, 'type' => 'cover-image' ) ) ) {
// Defaults no cover image
$response = array(
'reset_url' => '',
'feedback_code' => 3 ,
);
// Get cover image settings in case there's a default header
$cover_params = bp_attachments_get_cover_image_settings( $component );
// Check if there's a default cover
if ( ! empty( $cover_params['default_cover'] ) ) {
$response['reset_url'] = $cover_params['default_cover'];
}
// Finally send the reset url
wp_send_json_success( $response );
} else {
wp_send_json_error( array(
'feedback_code' => 2,
) );
}
}
add_action( 'wp_ajax_bp_cover_image_delete', 'bp_attachments_cover_image_ajax_delete' );
and lastly I know that cover images are usually stored in the members/{id}/cover-image/ folder, Worse case scenario is when they click the button it just grabs their user ID and deletes the appropriate file or directory?
