[Plugin: Web Invoice – Invoicing and billing for WordPress] PHP Warning on payment methods convert t

  • There is PHP Warning occurred when trying to create invoice from template:
    Warning: join() [function.join]: Invalid arguments passed in /home/smth/public_html/smth/wp-content/plugins/web-invoice/Functions.php on line 2290
    web_invoice_payment_methods meta value, that plugin gets from DB, is stored as string. But plugin use join when trying to convert them to array:
    $web_invoice_payment_methods = join(',', $_REQUEST['web_invoice_payment_methods']);
    You are wrong. You need to use explode, not join :).

    UPD. When creating new invoice – the data is returned in array. But when creating invoice from template – the data in returned as string with commas. You need unify the returned data.
