试图弄清楚为什么一个sub导致27个条目进入mysql数据库

Question

So I have a subroutine in my software that generates a temporary invoice. I really only need the temporary invoice to then add line items to it and publish the invoice for payment. All works well expect the snip of code causes a number of temporary invoices to be generated. I say a number because one time it will be 27 then the next time will be 26.. 25.. 20... and so on.. I don' see anything on here that would loop the sub to cause this. Typically all db calls are done from a separate file and called via a sub but for reference Ive added it into the sub. ** I have removed parts of the code at a time to see if it was causing it, found no issues. I have also tried adding a temp invoice via the sub call from another page without issue. My issue is in this code somewhere!

Answer 1

Instead of all those selects, do just one??

$sql = "SELECT fname, lname, ...
    FROM customer
    WHERE customer_id = '$customer_id'";

The result is an array of fname, lname, etc.

Answer 2

I ending up figuring out the issue with some help from a user over at reddit. Since Im using mod rewrite apparently items were being called under the link causing the main program to run X extra times and create the random junk entrees. Needless to say it had nothing to do with the script at all!
