Good.
What is the best way to pass an input value to a session variable in php without reloading the page?
For example, with this method the page does the reload:
<form method="post">
<input type="text" name="valor1" onchange="submit()">
</form>
<?php
session_start();
if($_POST['valor1']){
$_SESSION['valor1'] = $_POST['valor1'];
}
?>
How can I get the same result without reload?
Using asynchronous loading, using Ajax.
Example with jQuery:
Form.php Page
<html>
<body>
<form>
<form method="post">
<input type="text" name="valor1" id="valor1">
</form>
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><script>$("#valor1").change( function(){
$.ajax({
type: 'POST',
url: "salvarNaSessao.php",
data: 'valor' + $("#valor1").val()
}).done(function() {
alert('dados enviados');
});
});
</script>
</body>
</html>Page saveNaessess.php
<?php
session_start();
if(isset($_POST['valor1'])){
$_SESSION['valor1'] = $_POST['valor1'];
}
?>
