I have a simple form and I run my script without any errors. I click my btn and I would like to see my echo errors but no errors show up when I have no value in textboxes. I have tried if(isset($_Post["submit"])) and if($_SERVER["REQUEST_METHOD"] == "post") What I think is nether of there ifs are becoming valid on my btn click.

<?php
$nameerror = $twoerror = $errormsg = "";
// PHP Procedural MYSQLi
// connect to mysql database with phpmyadmin
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "test";

$connection = new mysqli($servername, $username, $password, $dbname);
//if(isset($_Post["submit"]))
if($_SERVER["REQUEST_METHOD"] == "post")
{
    if(empty(trim($_Post["name"]))) {
        $nameerror = "Name is required";
    }
    else {
        $namesafe = mysqli_real_escape_string($connection, $_Post["name"]);
    }
    if(empty(trim($_Post["two"]))) {
        $twoerror = "Two is required";
    }
    else {
        $twosafe = mysqli_real_escape_string($connection, $_Post["two"]);
    }

    if($namesafe != "" && $twosafe != "") {
        $sqlInsert = "INSERT INTO tester(name, two) " .
          "VALUES('". $namesafe ."','". $twosafe ."')";

          if(mysqli_query($connection, $sqlInsert)) {
              echo "Successfully entered.";
          } else {
              echo "NOT successful error: " . $sqlInsert . "<br>" . mysqli_error($connection);
          }
    } 
}
mysqli_close($connection);
?>
<?php

      if(!$connection) {
        die("Connection Failed! " . mysqli_connect_error());
      }
      echo "Connected Successfully@!";

                <?php
                    if(isset($errormsg)) {
                    //  echo "<div><span>";
                      echo $errormsg;
                    //  echo "</span></div>";
                    }
                 ?>
                <div>
                    <div class="form-group">
                        <input type="text" class="form-control" id="txtName" name="name" />
                        <label for="txtName">Name </label>
                        <?php if(isset($nameerror)) { echo '<span class="error">' . $nameerror . '</span>'; } ?>
                        <!-- ? php//if(isset($_Post["name"])) echo htmlspecialchars($_Post["name"]); ? >" /> --->
                        <!-- <span class="error"><?php //echo $nameerror; ?></span> -->

                        <?php if(isset($twoerror)) { echo '<span class="error">' . $twoerror . '</span>'; } ?>
                    </div>
                </div>
                <button type="submit" class="btn btn-lg btn-primary btn-block" name="submit">Click</button>

What I have tried:

I have been trying with internal php files and external php I just want to ...
This is basically my whole file without the bootstrap CDNs
I can run my page and I get no errors I tried to setup php-debug and xdebug on atom and chrome I cant count how many tutorials I have used and tried but for some reason my breakpoints will not turn green on atom. and stop to the IDE when i run the page.

I would refresh the page and in the network tab I would see my .php file and if i had somekind of error like at first it says no function mysql_connect so i realized i needed to use mysqli_connect

I use xampp with myphpadmin to connect to mysql.

I just want to do these simple check if row exists in db and create in db then ill do a login and crud and shopping cart etc.. but i been having troubles just setting up the debugger if i had that i know everything would be easier so i can see exactly whats going on
