Sample educational css js and html project to add, amend, view, delete records from mysql database usin php / mysqli

I have most of the code and examples, I just need it simplified, explained and commented and a simple demo version - this should not take long, so I dont want to mess around with complicated milestones, just one milestone for payment on completion - do NOT want requests for more money, pay some now, tell me it is completed when it is not. Simple job, do it, i test it, when its ok - i pay agreed amount. I am learning css and js, I am familiar with html and forms but this limits me. For educational purposes (LOW budget) i need a sample scripts to enter, view, edit and delete records (rows) from a mysql table using css and js. I have most of the code and examples but i need them simplified and commented and explained so I can move fields around. My problem is I can use html and forms with tables but i want to learn how to layout a form, with input fields, validation a logo / image and update msql database using php / mysqli. It is a very simple project and good commenting is needed so I can play with the code. I need 6 fields:- id (int) auto increment name varchar 30 index date date field (yyyy-mm-dd) value dec 2 (99.99) email varchar 40 comments ( text box 500 chars that recognises line feeds, enter) also a simple drop down css / js menu I need scripts to :- display the form and enter data enter a name and display the data - no edit enter a name and edit the data enter a name and delete the row the date field should be based on a popup calendar such as datepicker and should update the date field. When you edit the form if you click the date field the calendar should appear again with current stored date highlighted The main thing i need is good comments so I can change field positions, colours, borders etc I can supply database, table, current code that I have i just need a simple i have code for list, update, delete, I have a form with datepicker that already works, i just need someone to use it to poduce a simple commented version for me to learn from.
