I finally got some of the kinks out, obviously I had my paths crossed lol .. 

anyway now I need to figure out why all my fields are not showing values, and my update and insert are not working.. 

Here is the code

<? ob_start(); ?>
<?php
        /*
                Allows the user to both create new model and edit existing model
        */

        // connect to the database
        include("connectme.php");

        // creates the new/edit record form
        // since this form is used multiple times in this file, I have made it a function that is easily reusable
        function renderForm( $infantPatientid ='', $roomNumberId = '', $patientFirstname = '', $patientLastname = '', $patientAddress = '', $patientPhone = '', $patientEmergencycontact = '', $error = '', $patientId = '')
        { ?>

I have changed the "s" to an "i" for the emergency contact, I am not sure if BIGINT is an "s" or an "i" also I am not sure if that is what I am supposed to use for phone numbers? I am new to this trying to learn.. anyway I have to do a lunch meeting, I will check back for more advice

I have changed the "s" to an "i" for the emergency contact, I am not sure if BIGINT is an "s" or an "i" also I am not sure if that is what I am supposed to use for phone numbers? I am new to this trying to learn.. anyway I have to do a lunch meeting, I will check back for more advice

s is for strings (char, varchar, text datatypes etc)

i is for integers (int, tinyint, bigint datatypes etc).

 

Int datatypes only allow positive/negative numbers and nothing else. if you are allowing spaces/dashes in your phone numbers (eg 1234 555 666 or 1334-555-666) then you need change the column type from an int to a varchar. Then you'd use s for bind value.
