How to Pass JavaScript Variables to PHP Variables to Preserve Google Maps Data

Passing JavaScript Variables to PHP Variables: A Solution for Preserving Google Maps Data

In certain scenarios, developers may encounter the need to transfer data from JavaScript variables to PHP variables. A compelling instance of this is when obtaining coordinates from Google Maps and aiming to store them within a MySQL database.

Consider a JavaScript variable named lugar that holds latitudinal and longitudinal coordinates. To pass this value to the PHP variable of the same name ($lugar), a seamless approach can be achieved through jQuery's Ajax capabilities.

The Ajax Method

1. Prepare the Database Save Script: Create a PHP script (e.g., "save.in.my.database.php") designed to receive $_POST['lugar'] data and save it in the MySQL database.
2. AJAX Transmission: The HTML script below initiates the AJAX transmission.

<code class="html"><script>
  $.ajax({
    url: "save.in.my.database.php",
    type: "post",
    dataType: "json",
    data: { lugar: results[0].geometry.location },
    success: function(data) {
      alert('Saved!');
    },
    error: function() {
      alert('Error encountered.');
    }
  });
</script></code>

This script transmits the lugar variable to the PHP script, which then handles the database saving process.
