Add php log-in script to html page.

You most certainly need a script page for database connectivity if you have a user database which could be a database server, text file or xml file .
Option for script could be a php or javascript.
A simple example using php is
http://www.html-form-guide.com/php-form/php-login-form.html
where as if you wants to use javascript

This article is my teaching example that shows all the essential moving parts.  Have a read and let me know if you have any questions.

Going forward in your web experience, just "forget" about HTML pages and think "100% PHP" forever.  PHP is a server-side language that generates HTML.  If you're smart about it, you will write much less HTML and much more PHP because PHP promotes reuse of data objects, including HTML documents.  For your existing HTML pages, you can add the PHP capability by simply parsing HTML documents through PHP.  The parser will ignore anything that is not captioned with <?php start tag, and if you want to add PHP at any time, the parser will use the PHP instructions.

Here is a sample of a web page showing how PHP can make your coding more efficient.
http://www.landonbaseball.com/basic.php
The entire PHP document is here:

<?php // landonbaseball.com/basic.php
require_once('_config.php');
require_once('_header.php');

echo '<p>Hello World</p>' . PHP_EOL;

require_once('_footer.php');

Best regards, and welcome to PHP, ~Ray

greetings KLM56 , , as said already, you really should take some time and learn the basics of PHP, not just reading about it, but doing very many "Test" scripts (php files on your server), this is particularly important for the database access in PHP code. Setting up database tables with useful and proper columns (fields) and then use INSERT, SELECT and UPDATE  SQL statements to change and get info on database will not happen in a few days of study. But there are hundreds of PHP tutorial web sites and pages available. One of  a php developer's greatest help is learning how to google (yahoo, bing) search for the code examples that you need for a particular project, there's not much in PHP development that has NOT been done already many times.


Maybe this can help you, some "for real" MySQLi (improved) code, many times most of the "Old" MySQL coders do not understand the new coding setups of the Improved version.

$mysqli = new mysqli('localhost', 'user', 'passw', 'DB_name');
	if (!mysqli_connect_errno()) {
		$query = 'INSERT INTO coolo (name1, user1, asoc1, belong2, noton1) VALUES (?,?,?,?,?)';
// IMPORTANT use PREPARE for ALL user input (From POST or GET)
		$stmt = $mysqli->prepare($query);
// execute will READ the REALTIME values of the bind_param variables when execute is called
		$fname = 'Loco Menendez';
		$uname = 'Loco';
// Comma-separated values  CSV data
		$asoc1 = 'TVA,NRA,CCA,DDT,GDC,USA';
		$belong = 533;
		$ton1 = 'DDT';
// IMPORTANT, you MUST Bind the Variables to the the $stmt
		$stmt->bind_param("sssis", $fname, $uname, $asoc1, $belong, $ton1);
		if(!$stmt->execute()) echo 'execute has failed<br>'; else echo 'Rows Inserted '.$stmt->affected_rows.'<br>';
// You can Call $stmt->execute() as many times as you need, just CHANGE the variables for different inserts
		$fname = 'fuffy pink';
		$uname = 'pinky';
		$asoc1 = 'OOH,WOW,HOW,PRE,TTY';
		$belong = 121;
		$ton1 = 'HAT';
// this execute will read the NEW values of the BIND variables
// this is NOT at all like the OLD MySQL function calls
		if(!$stmt->execute()) echo 'execute has failed<br>'; else echo 'Rows Inserted '.$stmt->affected_rows.'<br>';
		$stmt->close();
	echo '<br>Stats : '.$mysqli->stat().'<br>server info : '.$mysqli->server_info.'<br><br>';

// use $mysqli->query just like the OLD MySQL code setups, But it does NOT offer any improved security
	if ($result = $mysqli->query('SELECT * FROM coolo')) {echo 'Number returned rows: '.$result->num_rows.'<br>';
		while ($row = $result->fetch_object()) {echo 'ID: '.$row->id.' user1 '.$row->user1.' name1 '.$row->name1.' asoc1 '.
			$row->asoc1.' belong2 '.$row->belong2.' noton1 '.$row->noton1.'<br>'; 
		}
		mysqli_free_result($result);
		} else echo $mysqli->error;
	$mysqli->close();
	} else echo '<b>BIG mysqli ERROR - did NOT create the mysqli Object '.mysqli_connect_error().'</b>';

you might do well to learn the improved mysqli instead of MySQL or the "wrapper" PDO stuff.
