Code functionality and fix some issues

I will provide you with a basic database setup and design for a small journal-system that I've made, however there are a lot of things that I cannot do. What I want you as developer to do is to first check the files that already exist if they are secure and correctly setup. After that I need you to code the rest of the system for me that includes: - Creating a post from another related table (*1) - Autoamtic SMS LIST based on the date (*2) - File uploading, for a multiple documents assigned to the customer - Maybe small photo management (not entirely sure yet). ! There might be some more of the tasks to do, but these are the main ones. ________________________________________________________________________________________ *1 - Think that you have a web-form to fill out so the user does not see the post, and when the button is pressed it checks the data and publishes it to the main database and the form returns to it's original phase. *2 - I have some code from the SMS Host on how to send the message but I don't know how to make it happen automatically. I just want a simple list where I can put name and phone and a date, and an sms will be send to that person 1 day before that date.
