4、 Improvement of warehousing management function

One 、 Database creation

stay fiber_yy Create... Under database yy_textile surface

Just add a few pieces of data

Two 、 Page perfection

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

warehousing Warehousing page

main_page The function of the page is improved

3、 ... and 、 Code implementation

warehousing page
