All a bit new to HTML, PHP and phpMyAdmin link up. Was having trouble sending form information from HTML to PHP.
My HTML code Login.html:
<form role="form" action="insert.php" method="post">
                        <div class="row">
                            <div class="col-xs-6 col-sm-6 col-md-6">
                                <div class="form-group">
                        <input type="text" name="fn" id="fn" class="form-control input-sm" placeholder="First Name">
                                </div>
                            </div>
                            <div class="col-xs-6 col-sm-6 col-md-6">
                                <div class="form-group">
                                    <input type="text" name="ln" id="ln" class="form-control input-sm" placeholder="Last Name">
                                </div>
                            </div>
                        </div>
                        <div class="form-group">
                            <input type="location" name="loc" id="loc" class="form-control input-sm" placeholder="Location">
                        </div>
                                                <div class="form-group">
                            <input type="email" name="email" id="email" class="form-control input-sm" placeholder="Email Address">
                        </div>
                                                <div class=" form-group">
                          <h4 >Gender</h4>
                          <input type="radio" name="gender" value="male"> Male 
                          <input type="radio" name="gender" value="female"> Female
                        </div>
                    <input  type="submit" value="Register"  onClick="signup();" class="btn btn-info btn-block">
                    </form>
My PHP code insert.php
<?php
 $dbhost = "localhost";
 $dbuser = "root";
 $dbpass = "1234";
 $db = "client";
/*
$first=$_GET("fn");
$last=$_GET("ln");
$location=$_GET("loc");
$email=$_GET("email");
*/
$connect = mysqli_connect($dbhost,$dbuser,$dbpass, $db);
mysqli_query($connect, "insert into client () values($_POST[fn]', '$_POST[ln]', '$_POST[email]', '$_POST[loc]')"); 
/*mysqli_query($connect, "insert into client values('user','name','afggei@ggwp.com','tumbartk')");  */
?>
The Error I receive:
Notice: Undefined index: fn in C:\xampp\htdocs\marion\insert.php on line 14
Notice: Undefined index: ln in C:\xampp\htdocs\marion\insert.php on line 14
Notice: Undefined index: email in C:\xampp\htdocs\marion\insert.php on line 14
Notice: Undefined index: loc in C:\xampp\htdocs\marion\insert.php on line 14
The connection does establish and work as I've tested the below code.
mysqli_query($connect, "insert into client values('user','name','afggei@ggwp.com','tumbartk')");
