Glad to know this can be done without too much hassle. I appreciate the help, Ben.
However… I have tried this in several different places and looked for php tags that needed tending… I cannot get this to work.
I just keep getting the white screen.

I edit the relocated /dashboard/product-edit.php template, correct?

It seems like there is one too many or one too few <?php and/or ?> but I cannot tell where….

Here is what I have done:

<?php
/**
 * The template for displaying the Product edit form  
 *
 * Override this template by copying it to yourtheme/wc-vendors/dashboard/
 *
 * @package    WCVendors_Pro
 * @version    1.2.0
 */
/**
 *   DO NOT EDIT ANY OF THE LINES BELOW UNLESS YOU KNOW WHAT YOU'RE DOING 
 *   
*/

$title = 	( is_numeric( $object_id ) ) ? __('Save Changes', 'wcvendors-pro') : __('Add Product', 'wcvendors-pro'); 
$product = 	( is_numeric( $object_id ) ) ? wc_get_product( $object_id ) : null;

// Get basic information for the product 
$product_title     			= ( isset($product) && null !== $product ) ? $product->post->post_title    : ''; 
$product_description        = ( isset($product) && null !== $product ) ? $product->post->post_content  : ''; 
$product_short_description  = ( isset($product) && null !== $product ) ? $product->post->post_excerpt  : ''; 

/**
 *  Ok, You can edit the template below but be careful!
*/
?>
<?php
$access_token = get_user_meta( $vendor_id, '_stripe_connect_access_key', true );
if ( empty( $access_token ) ) {
   // BEGIN PRODUCT FORM

   // Put the ENTIRE add/edit product form here.  Keep in mind if you need to close/open PHP tags at the beginning or end of the product form.

<h2><?php echo $title; ?></h2>

echo 'Before you can add or edit products, you must connect to STRIPE, so you can receive the funds from your sales.  To connect to Stripe, <a href="/dashboard/settings/">visit the seller dashboard</a> and click the PAYMENTS tab.';
}
?>

I’ve tried moving both ends of the code around, and I just can’t get it to work. I’m probably doing something wrong with the <?php and ?> but I cannot figure out where.

Thanks, Ben!
That’s a nifty tool- thanks for sharing that site. It will help me in the future.

I definitely see what I did. I danced around the right opening/closing tags … didn’t quite get it.

HOWEVER… so far in my testing, a vendor that has not yet connected with Stripe is still able to add products. ? I’ll keep testing, but this code does not seem to be working at this point.

Thanks, Ben.

I followed your directions, and there are no access token numbers showing.
I logged in as both a vendor with and then a vendor without a stripe account connected.
