    Mac & Req,

    Here is the full script. Not finished yet. Especially, html form part.

    ISSUE: 1.
    I am having one problem.
    When user inputs wrong user details and clicks "Log-in" button, then he gets shown a complete blank page with error message:
    "Incorrect log-in details". 
    Login form disappears from the page.
    This is due to the "exit()" on this lines 59-63: 

    
if (!password_verify($login_password,$db_password)) 
    { 
        echo "Incorrect log-in details<br>"; 
        exit(); 
    } 

    Now, if I remove the "exit()", then user gets the same error if his login details are incorrect but the login form still remains on the page. This is what I want so user not have to click BACK button on his browser. But, keeping the "exit()" still runs the script. Waste of bandwidth and/or cpu usage.

    Shall I replace it with die() to achieve what I want or do something else ?

    Q1a.
    How to solve this so script halts but user still sees the login form. And, I want his input to still remain in the form fields and so why don't they especially when I have echoed the form inputs variables like so: 

    
<h2><p align="center"><?php echo "$site_name Member Login Form";?></p></h2> 
<form name = "login_form" method = "post" action="" enctype = "multipart/form-data"> 
    <fieldset> 
        <label for="login_name">Username/Email:</label> 
        <input type="text" name="login_username_or_email_or_domain" id="login_name" required [A-Za-z0-9] autocorrect=off value="<?php if(isset($_POST['login_username_or_email_or_domain'])) { echo htmlentities($_POST['login_username_or_email_or_domain']); }?>"><br> 
        <label for="login_pass">Password:</label> 
        <input type="password" name="login_password" id="login_pass" required [A-Za-z0-9] autocorrect=off value=""> 
    </fieldset> 
    <div class="SubmitsAndHiddens"> 
        <label for="login_remember">Remember Log-in Details:</label> 
        <input type="checkbox" name="login_remember" id="login_remember" /> 
        <br> 
        <p align="left"><input type="submit" class="btn btn-default" name="submit" value="Log-in!"></p> 
        <br> 
        <a href="login_password_reset.php">Forgot your password ? Reset it here!</a> 
        <br> 
        <a href="register.php">Don't yet have an account ? Register here!</a> 
    </div> 
</form> 

    Note the "value=" in the input field: 

    
<input type="text" name="login_username_or_email_or_domain" id="login_name" required [A-Za-z0-9] autocorrect=off value="<?php if(isset($_POST['login_username_or_email_or_domain'])) { echo htmlentities($_POST['login_username_or_email_or_domain']); }?>"><br>         

    Q1b.
    Should I do the same echoing of the variable in the "Password" input field or not  ? Like so: 

    
<input type="password" name="login_password" id="login_pass" required [A-Za-z0-9] autocorrect=off value="<?php if(isset($_POST['login_password])) { echo htmlentities($_POST['login_password']); }?>">    

    ISSUE: 2.
    Look at this form I found here:
    https://www.tutorialrepublic.com/php-tutorial/php-mysql-login-system.php
    Why is it echoing in "action=" like this: 

    
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">

    Q2a.
    Why not like so: 

    
<form action="" method="post">

    
	<!DOCTYPE html>

	<html lang="en">

	<head>

	    <meta charset="UTF-8">

	    <title>Sign Up</title>

	    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.css">

	    <style type="text/css">

	        body{ font: 14px sans-serif; }

	        .wrapper{ width: 350px; padding: 20px; }

	    </style>

	</head>

	<body>

	    <div class="wrapper">

	        <h2>Sign Up</h2>

	        <p>Please fill this form to create an account.</p>

	        <form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">

	            <div class="form-group <?php echo (!empty($username_err)) ? 'has-error' : ''; ?>">

	                <label>Username</label>

	                <input type="text" name="username" class="form-control" value="<?php echo $username; ?>">

	                <span class="help-block"><?php echo $username_err; ?></span>

	            </div>    

	            <div class="form-group <?php echo (!empty($password_err)) ? 'has-error' : ''; ?>">

	                <label>Password</label>

	                <input type="password" name="password" class="form-control" value="<?php echo $password; ?>">

	                <span class="help-block"><?php echo $password_err; ?></span>

	            </div>

	            <div class="form-group <?php echo (!empty($confirm_password_err)) ? 'has-error' : ''; ?>">

	                <label>Confirm Password</label>

	                <input type="password" name="confirm_password" class="form-control" value="<?php echo $confirm_password; ?>">

	                <span class="help-block"><?php echo $confirm_password_err; ?></span>

	            </div>

	            <div class="form-group">

	                <input type="submit" class="btn btn-primary" value="Submit">

	                <input type="reset" class="btn btn-default" value="Reset">

	            </div>

	            <p>Already have an account? <a href="login.php">Login here</a>.</p>

	        </form>

	    </div>    

	</body>

	</html>
