Now itās saying every entry i add is in the DB when in fact i know its notā¦ & i cannot work out why. GRRR spent days on this.
Iām quite certain that EngineersName is not a valid html input type:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input
I suppose that i could be wrong.
also, a closing tag is not necessary but xhtml will expect a closing slash:
<input class="form-control" type="text" name="EngineersName" />

Since you have made a number of changes to your code, you should post the current code so that members arenāt trying to solve problems that no longer exist.

yes, please 
In the meantime, start here:
include 'nav.php';
require 'ConnectionDB.php';then be certain that you only process a post request:
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['submit'])) {
$result = create_eng();
}you can filter a post individually or many post values via array:
$eng_name = trim(filter_var($_POST['EngineersName'], FILTER_SANITIZE_STRING));no need to set an empty display message:
$msg = '';
<?php display_msg($msg, $result);?>in fact, you should set $msg to $valid which will hold the return value of the function (true or error):
$valid = validate_eng($eng_name);
if ($valid !== true) { display_msg($valid); }
function validate_eng($post_eng_name) {
if ($post_eng_name === '') { return 'Please enter the engineers name'; }
if (!is_string($post_eng_name)) { return 'Invalid engineers name'; }
return true;
}let a function serve its purpose to perform a duty with a return value/output.
PHP does not have sub procedures but sanitizing post input is not good use of a function.
i have no idea why one would bypass a built-in reset for a a button and javascript:
<button type="input" class="btn btn-primary default" onclick="job_reset()">Reset Form</button>
<script>
function job_reset() {
document.getElementById("job_reset").reset();
}
</script>simply hire the reset input type to do its job:
<input type="reset" value="Reset">https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/reset
Nope, still doesnt workā¦ hereās the code. I am thinking of starting AGAIN.

I hope i have indented each page by 4 spaces to show correctly. thanks for all assistance but didnt think this project would be as difficult should 
My perspective is, you are trying to hard to simplify this into functions when you donāt understand what is needed to begin with.
Try something simple to get it working.
Is this a separate file? Or a continuation of one?
the entire script is a mess. I suggest that you spend time reading about html because you are not implementing valid html. You cannot place div tags inside of the head of an html document. You will have to accept the fact that programming takes time. You are trying to hurry and force the script to work or you are hoping that someone will code it for you, which is unlikely, unless, you hire them to do so.
the first thing that you should do try to understand the post and get requests. Your script needs to be separated into post processing and get request.
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['submit'])) {
require 'ConnectionDB.php';
$result = create_eng();
}
?>
<!--this is what is displayed if $_SERVER['REQUEST_METHOD'] == 'GET'. 'GET' it? -->

<body>
<?php include 'nav.php'; ?>
<div>all of your html code goes here</div>
</body>
</html>
<?php
//you can add all of your functions here
exit;
?>the fact that you are unable to code html correctly means that database handling, error handling and post form processing is out of reach for you at the moment. Start over and take it step-by-step. Build a valid html document with a form. Then add the post processing code and test it. Then continue with the rest of the code.
I donāt have the time right now, but I agree with John.
You are pushing ahead without making any progress, which will just slow you down, as you are seeing.
Start with a basic html page and the form.
Next, do the processing that will insert the data.
You have so much embedded, that you canāt keep track of each section currently. And the process flow is hindered by all of the needless functions, that I think you got the idea you needed to use to simplify things. Rather than simplification, it is making the process more convoluted.

And if you decide to seek a freelancer, then you can post in the freelance section of this site:
https://www.phphelp.com/c/php-freelancing
PHPHelp.com has many highly-skilled programmers (excluding myself. Iām a novice.) I think that the freelance section of this site is useful resource.
Its a continuation of the script
Thnaks of the advice i wont be using a freelancer as this is my project & i dont like being beaten. I will have a look a the html form and start basic.

Thank you i have recreated my code taking in everyoneās comments. I am actually rewriting it ask we speak and will take what you have supplied onboard and re-adjust where needed appreciate all comments given as you all can tell i am a novice.
