Question

is it possible to make a function that takes form data and executes a php file on the spot without having to leave the page? Thanks :))

Answer 1

without an actual submit, but still with a buttonclick you could do it like this:

html:

<form>

  <input type="text" id="name"></input>
  <input type="text" id="age"></input>

  <input id="myButton" type="button"></input>

</form>

javascript:

$('#myButton').click(function(){
  var data = {
    name: $('#name').val();
    age: $('#age').val();
  };

  $.ajax({
    type: 'POST',
    url: 'http://www.mydomain.com/myphpfile.php',
    data: data,
    success: function(){
      alert('done...');
    }
  });
});
