By clicking on my Ubmit, the php function is opening my file

Question

I have the following file called teste3.php:

<form action="cadastros.php" method="post">

<label for="latitude" hidden>Latitude:</label>
<input id="latMap" hidden name="latitude"/>

<label for="longitude" hidden>Longitude:</label>
<input id="lngMap" hidden name="longitude"/>

<input type="hidden" name="acao" value="inserir">

<input type="submit">

</form>

When I click on Submit, this function is called in my.php register file.:

if(isset($_POST['acao'])){
    if($_POST['acao'] == "inserir"){
    cadastraLatLong();
  }
}

function abrirBanco(){
    $conexao = new mysqli("localhost", "root", "", "cademeupet");
    return $conexao;
}

function cadastraLatLong(){
  $latitude = $_POST['latitude'];
  $longitude = $_POST['longitude'];

  $banco = abrirBanco();
  $sql = "INSERT INTO marcadores (id, descricao, lat, lng, tipo) VALUES (NULL, 'teste', '$latitude', '$longitude', 'testetipo')";
  $banco->query($sql);
  $banco->close();
  header('Location: teste3.php');
}

When I click on the Submit button, the.php register file opens and shows the following:

Answer 1

The path specified in the address bar is from the file on the machine, so it does not run the file on the server.

You need to use the localhost path defined by xamp.

Example: localhost/cadastre.php
