 //TODO:Register

var mysql=require   ('mysql');

var con=mysql.createConnection({
    host:"localhost",
    user:"root",
    password:"",
    database:"progmeet_database"

});





function Register(){
    //Value Takers
    var name_input_value=document.getElementById("Progmeet_register_page_name_and_surname_input").value;
    var username_input_value=document.getElementById("Progmeet_register_page_username_input").value;
    var Phonenumber_input_value=document.getElementById("Progmeet_register_page_phone_number_input").value;
    var DOB_input_value=document.getElementById("Progmeet_register_page_DOB_input").value;
    var password_input_value=document.getElementById("Progmeet_register_page_password_input").value;
    var email_input_value=document.getElementById("Progmeet_register_page_email_input").value;

    //Database appender
    var Insert_into_value="INSERT INTO progmeet_user_info_table (name,username,Phonenumber,DateOfBirth,Password,Email),VALUES('namex','usernamex','Phonenumberx','DOBx','passwordx','emailx')";
    Insert_into_value.replace("namex",name_input_value);
    Insert_into_value.replace("usernamex",username_input_value);
    Insert_into_value.replace("Phonenumberx",Phonenumber_input_value);
    Insert_into_value.replace("DOBx",DOB_input_value);
    Insert_into_value.replace("passwordx",password_input_value);
    Insert_into_value.replace("emailx",email_input_value);
    con.query(Insert_into_value,function(err,result){
        if(err) throw err;
        console.log("suscess!");
    });
    alert("cihantoker")
};

con.connect(console.log("connected!"));
