[WebERP-developers] PHP help for PO_PDFPurchOrder.php

[Ricard A. <pak...@gm...>]

Hi all:

I need to modify the line 261 of PO_PDFPurchOrder.php as sometimes,
suppliers_partno is not included in itemdescription (depending on the order
of data entry). Sometimes PO gets prepared first and then we realize some
data is missing in purchdata. Once we fill it up it does not show on the PO
again.

So, I would like to check if suppliers_partno is already included
itemdescription strings, to avoid the duplication. I checked the PHP
documentation but I've got confused.

Which is the correct PHP function to check if string A is included (a part
of) string B?


Regards,
Ricard
