6、 Implementation of warehouse out management function

One 、 The establishment of database

Still used here yy_textile surface
stay fiber_yy Create... Under database yy_textile surface


Initial database information

Two 、 Page perfection

I won't show you on the login page , The previous blog posts also introduced

shipment Issue management page

main_page The function of the page is improved

3、 ... and 、 Code implementation

demonstration Warehouse out management function

View fabric information

Out of stock 20


retrieval once

When inventory is below 100 Will remind you when , And at this time, you can no longer leave the warehouse , Additional fabric is needed
