creating parts of a website stocklist

i had to shorten project description. please see full description in text file attached. Linuxbased web-server to test, later website will run on windows server2012 (keep care of upper/lower letters and so on), MySQL Database, Domain, bootstrap template you have to use php framework cakephp you have to use bootstrap html framework I WANT: - clear and struktured programming using classes and subclasses - everything only in good and plain english - easy understanding of the code: use comments - later i want to be able to use the code by myself and insert it into own intrasite. - seperate design, css and code like php, java and so on. Clear Filestrukture where i can find easy what i need to find! what i need. Functions to manage articles in stocklist. Its a little bit complex: functions i thought of: create new article edit existing article delete article function to upload one ore more images of the article function to generate a barcode lable to print out (barcode with article number the article name and some more information of the article) function to add article into a stock shelf (each shelf has its unique number) create new warehouse edit warehouse create shelf and connect with warehouse (unique numbers) edit shelfs create new article_menuepoint edit article_menuepoint delete article_menuepoint create options for article edit options for article subfunctions: generate articlenumber articlelist_menue: should be a tree where i can sort article into different menuepoints for example i want to have a menue something like this: root laserprinter HP Color laserjet 3800 Kyocera KM-2602 KM-2104 TFT 24inch Fujitsu HP 22inch Dell HP Brother now its getting complex and tricky: i need different options for different articles in different menuepoints / variable variables: for example everything which is below the menue point laserprinter: i need the filds for "Toner black" = 20(%) (Header and numeric value) "Condition consumables" = A+ (header and predefined value = A+, A , B, C) "USB" = YES/ No (header and 1 or 0) "optional things" = "text" header and textfield) "more things" = "word" (header and input field varchar) for menuepoint TFT i don't need the values of laserprinter but i need "inch size" = "22" (numeric field) I want to define the options when i crate a new menuepoint. All child menue points should adopt field of the parent menue point and i should be able to add more field to the child menuepoints For exampe manue point root->laserprinter->HP should have all the field of root-> laserprinter plus field "Someotherfield" = "test" (textfield) It should be also possible to lock some values so that i can pre define a value and user can not change the value. for example weight, size... (menue menue points have the same printer model but just slightly different, so weight will always the same) An it shopuld be possible to mark fields as "necessarry". So user has to fill them out practical site: lets do some practical example: see file attached After i finished system will lead me to stocklist . Later i will have user right function. so i will have a logged in user and rights. thats not ready yet. we will insert this later. user will get rights for add, delete and edit article,add, delete edit menuepoints, add edit warehouse and shelfs. for now plase make a markout placeholder like #########CHECK FOR RIGHT ############## define what happend if user has right and what will happen if user has no right (error message or that menue point is not seen by user).
