Wordpress Filters

I have attempted to ask this question before but I don't think I was being clear enough and I also know just enough to make me dangerous!
I want to create a Wordpress Filter to change a line of code within a Core Function in Wordpress / Woocommerce.

The Worpress / WooCommerce function is as follows:

	public function edit_columns( $existing_columns ) {
		$columns = array();

		$columns['cb']               = '<input type="checkbox" />';
		$columns['order_status']     = '<span class="status_head tips" data-tip="' . esc_attr__( 'Status', 'woocommerce' ) . '">' . esc_attr__( 'Status', 'woocommerce' ) . '</span>';
		$columns['order_title']      = __( 'Order', 'woocommerce' );
		$columns['order_items']      = __( 'Purchased', 'woocommerce' );
		$columns['shipping_address'] = __( 'Ship to', 'woocommerce' );

		return $columns;
	}

Open in new window

I have followed the directions offered by Wordpress but it is not working for me. I want to Replace The Word "Order" with the words "My Number" on line: 6

Here is what I have that is not working. (This filter is my Custon-Functions.php file)

function filterAdminLabels( $existing_columns ) {
	$labels = array('Order');
	$existing_columns = str_ireplace($labels, 'My Number', $existing_columns);	
}
add_filter ( 'edit_columns', 'filterAdminLabels', 2 );

Open in new window

eemit

Add this line:

return $existing_columns;

Open in new window

after the line:

$existing_columns = str_ireplace($labels, 'My Number', $existing_columns);

I tried that and nothing Changed. However, I did discover I was trying to hook into the wrong function. Here is the correct function and I want to replace the word Order with My Policy:
Wordpress Function

	public function shop_order_columns( $existing_columns ) {
		$columns                     = array();
		$columns['cb']               = '<input type="checkbox" />';
		$columns['order_status']     = '<span class="status_head tips" data-tip="' . esc_attr__( 'Status', 'woocommerce' ) . '">' . esc_attr__( 'Status', 'woocommerce' ) . '</span>';
		$columns['order_title']      = __( 'Order', 'woocommerce' );
		$columns['order_items']      = __( 'Purchased', 'woocommerce' );
		$columns['shipping_address'] = __( 'Ship to', 'woocommerce' );
		$columns['customer_message'] = '<span class="notes_head tips" data-tip="' . esc_attr__( 'Customer Message', 'woocommerce' ) . '">' . esc_attr__( 'Customer Message', 'woocommerce' ) . '</span>';
		$columns['order_notes']      = '<span class="order-notes_head tips" data-tip="' . esc_attr__( 'Order Notes', 'woocommerce' ) . '">' . esc_attr__( 'Order Notes', 'woocommerce' ) . '</span>';
		$columns['order_date']       = __( 'Date', 'woocommerce' );
		$columns['order_total']      = __( 'Total', 'woocommerce' );
		$columns['order_actions']    = __( 'Actions', 'woocommerce' );

		return $columns;
	}

Open in new window

My Function:

function filterAdminLabels( $existing_columns ) {
	$labels = array('Order');
	$existing_columns = str_ireplace($labels, 'Policy Number', $existing_columns);	
	return $existing_columns;
}
add_filter ( 'shop_order_columns', 'filterAdminLabels', 2 );

I followed the instructions but nothing happens. What do you think I am doing wrong?

eemit

I think you should use the filter: 'manage_edit-shop_order_columns'

eemit

add_filter ( 'manage_edit-shop_order_columns', 'filterAdminLabels', 2 );
